Message from Director
Prof. Sunil Kr Sarangi, FNAE Director
Scholarship thrives for communication; Institutes of higher learning prosper when faculty and students share their thoughts with each other. While conversation among faculty and students continue to be scientifically productive, more formal communication channels benefit everyone in the community. These formal channels include conferences, symposia, institute and departmental seminars, journals and magazines. Those are the category of communication media that give more effective sharing of thoughts among scientists around the globe. Departmental magazines in particular are good compromise between informal communication among closely related colleagues, and formal communication between professional peers over wider areas. Departmental magazines may be in print, in electronic media or even be pasted on the wall. They substantially enrich the scientific and cultural life of a department. These magazines give opportunity to everyone in the department, from senior-most professor to the youngest student to express his or her creative thoughts. I am indeed happy to learn that the faculty and students of our Chemistry Department have floated their departmental magazine. I am confident that with the support and cooperation of all faculty and students in the department, this magazine will grow from strength to strength with time. I congratulate the Head of the Department Professor B. G. Mishra, his team of young faculty colleagues and students of the Department for taking up this venture. I wish them all success in serving the Institute community interested in various aspects of chemistry.
Prof. Sunil Ku Sarangi
Editorial…..
Like an age old banyan tree; deep rooted in soil and numerously branched above the ground to arise as a symbol of growth and serene existence, our department of chemistry in NIT Rourkela has come across a long way since its inception in 1961 and standing taller than ever in 2012. Started as a sapling planted under the guidance of Prof. D. V. Ramana Rao, this department has truly embodied a grown up tree that patrons sixteen faculty members, 00 staffs, 00 students and 00 research scholars. Indeed, we are a part of a big family now. Complementing with the chemistry department’s existing academic heritage, we realize that it is the time to add a cultural perspective that is characteristic to every traditional family. On this note we felt that there should be a platform to express our thoughts, feelings and intellect in terms of words. It is our utmost pleasure to present you the first issue of our own departmental magazine ‘Chemunion’, where students and faculties can have their voices and literary talents shared. This magazine would be published annually. In general, it would include the updated faculty profiles and latest academic as well as cultural happenings of the department. Additionally there will be a group photo of all outgoing students of MSc (both 2 yr and integrated) batches so that Chemunion stays as a long lasting
memory for these students. Besides, there will be several literary and scholarly articles from faculties as well as students in each issue. Along with hardcopies, there will be an online edition of this magazine for general access. I consider myself extremely fortunate to be an active part of this departmental magazine. I would personally like to thank Anurag, Sandeep and every other integrated MSc student of the chemistry department for their hard work in making this project coming through. We are indebted to all the faculties of this department, especially Prof. B. G. Mishra for the helpful suggestions and guidance. Finally, we would like to thank our honourable Director, Prof. S. K. Sarangi for his support and best wishes that has propelled our magazine forward. We believe that Chemunion would one day become an indispensable part of the rich cultural tradition of NIT Rourkela and like a legacy it would continue for a long time in future.

Fe-Catalyzed One-Pot Synthesis of 1,3-Di- and 1,3,5-Trisubstituted Pyrazoles from Hydrazones and Vicinal Diols Abstract: Substituted pyrazoles are privileged structural units in many blockbuster drugs, pesticides, functional materials including optical brighteners, ultraviolet stabilizers etc. The rising usage of pyrazoles stimulates the development of new and complementary methods for their synthesis. The existing methods on synthesis of pyrazole often suffer from limitation on regioselectivity, explosive nature and sometimes multistep access of starting materials restricts their wide use. Furthermore use of expensive halides, transition metals poses the subsequent draw backs. In this context, recently we have developed an iron-catalyzed route for the regioselective synthesis
of
1,3-
and
1,3,5-substituted
pyrazoles
from
the
reaction
of
diarylhydrazones and vicinal diols. This method was found to be practical with wide substrate scope. Ref: N. Panda, A. K. Jena, J. Org. Chem. 2012, 77,9401-9406.
Stereo selective Synthesis of Enamides by Pd-Catalyzed Hydroamidation of Electron Deficient Terminal Alkynes Abstract: Pd-catalyzed hydroamidation of electron-deficient terminal alkynes by amides has been developed for the stereo selective synthesis of Z-enamides. The possible intramolecular hydrogen bonding between the amido proton and carbonyl oxygen of ester group provides the extra stability to the Z-isomer of vinyl-palladium complex, which subsequently undergoes protodepalladation and leads to the Zenamide selectively. This process is found to be mild and operationally simple with broad substrate scope. Ref: N. Panda, R. Mothkuri, J. Org. Chem. 2012, 77, 9407-9412.

Diverse field of Organometallic chemistry: Challenges and Opportunities Beginning of organometallic chemistry took place in the year 1760, with the synthesis of organoarsenic compound or Cadet’s “funming liquid” or “Cacodyl” by Louis Cadet de Gessicourt and later identified by Robert Bunsen as tetramthyldiarsine (Me 4 As 2 ) or its oxide (Cacodyl oxide). Thereafter, a series of development occurred with the synthesis of a variety of important organometallic compounds like Zeise salt 2 [KPtCl 3 ( -C 2 H 4 )] in 1827, Metal alkyls in 1850-1860, binary metal carbonyls in 1890-
91 and Grignard reagent at the beginning of the 20th century. The emergence of a major application in organometallic chemistry in catalysis evolved in the first half of 20th century. Among the most important were the heterogeneous hydrogenation of olefins using nickel by P. Sabatier, Fischer-Tropsch syngas (CO +H 2 ) catalysis, hydroformylation
of
olefins
by
dicobaltoctacarbonyl
(oxo
process),
Reppe’s
trimerization and tetramerization of alkynes, Ziegler-Natta polymerization catalysis etc. The discovery of the first sandwich complex, ferrocene, came much later in 1951 by Pauson and Miller, which opened almost a new branch of ferrocenyl chemistry and later their application as sensors made them an important molecule in optoelectronics and biological research. Silently and without much notice, another application of organometallic was slowly evolving along with catalysis. That was the development of bioorganometallic chemistry or medicinal organometallic chemistry. Paul Ehrlich’s discovery of salvarsan for the treatment of syphilis and structural analysis of Vitamin B 12 coenzyme by D. Crowfoot-Hodgkin are the beginning of modern medicinal organometallic chemistry. Research on bioorganometallic chemistry took momentum in 1990s and now a large number of researches are concentrated on compounds like metallocenes, half-sandwich complexes, metal carbonyl complexes, gold complexes etc. for their active role in antibacterial, antimalarial, anticancer, CO releasing agents, diagonistic and other biological activities. Organometallic compounds have also been found to possess potential for their use as photosensitizers in solar cells. A lot of research is going-on on that front as well.
The man who has confidence in himself gains the confidence of others.

For the last five years at NIT Rourkela, we have been concentrating on two main research on organometallic chemistry, first is the synthesis of transition metal cluster for the application in catalysis and nanoparticle synthesis and the second, in the area of bio-organometallic chemistry. In transition metal cluster two or more metal atoms are bound together by direct and substantial metal�metal bonds to form a three dimensional polyhedral geometry. A large variety of organometallic transition metal clusters are known containing homo or hetero metal atoms, a range of terminal and bridging ligands and with numerous unique structural geometry. Transition metal cluster chemistry has gained current attention due to their properties related to catalysis, optoelectronic materials and biological processes. In the last two decades, varieties of synthetic methodology have been developed for the synthesis of metal clusters with unique structural features and properties. Recent studies have shown that several heteronuclear metal clusters have been used as precursors for nanoparticle synthesis and heterogeneous catalysis. Our studies have been focused to develop methodologies for obtaining novel mixed metal clusters of desired structural and reactivity features. However, synthesis of metal cluster is a real challenge and their stability is one of the main concern. Therefore, a bunch of different strategies has been employed to synthesise higher nuclear metal clusters.
One of the strategies includes incorporation of main group atoms into
transition metal clusters which plays a key role in stabilizing the bonding network in the transition metal, non-metal clusters. In addition, attaching electro-active groups like ferrocene in transition metal clusters has been one of the approaches to tune the properties of the cluster molecule. Recently, we have been focussing our studies on transition metal phosphine cluster to modify, functionalize, tune and design higher nuclear metal clusters for nano-material studies and other materialistic properties.. Molecular compounds containing organometallic tags have been found to be potential therapeutics against major diseases and can play a vital role as tracers in immunological

bioorganometallic chemistry and is increasingly drawing much interest due to the development of a new class of organometallic compounds and their ability to play a leading role in the field of biology. The use of ferrocenyl derivatives as bioactive molecule has been established recently and several reports show that a large number of ferrocene containing compounds display interesting cytotoxic and DNA cleaving activities.
These new evaluations on the biological properties of organometallic
compounds are increasingly drawing much interest due to their distinctive properties and features concerning both organometallics and co-ordination chemistry. In view of the enormous opportunities in this area of bioorganometallic chemistry we have been engaged in designing several [(Ρ5-C 5 H 4 R)M] based organometallic compounds and investigate their reactivity and study their biological properties. While most of the global research is concentrated on ferrocene based system, we are exploring the possibility of other Cp based organometallic fragments for their role in biological properties. Although, the opportunities in this area of biorganometallic research are vast, there are formidable challenges not only to synthesise and design organometallic compound but also to understand the mechanism of action of organometallic drugs in the biological processes.

Electrospun Nanofibers: Fabrication, Functionalization and Environmental Applications. Summary: Although there are many methods of fabricating nanofibers, electrospinning is perhaps the most versatile process. Materials such as polymer, composites, ceramic and metal nanofibers have been fabricated using electrospinning directly
or
through
post-spinning
processes.
However,
what
makes
electrospinning different from other nanofiber fabrication processes is its ability to form various fiber assemblies/morphologies as shown in the figure below. In electrospinning process polymer nanofibers (with diameter 50 nm to 1Âľl and lengths up to meters) can be produced using an electrostatically driven jet of polymer solution (or polymer melt). These nanofibers produced are useful in a wealth

Presently, my group research activities are on the synthesis of alumina-iron oxides ceramic nanofibers by electrospinning method and its application for removal of toxic metal ions such as As, Hg, Cd, Pb etc. from aqueous stream via adsorption/ chemisorptions process. Apart from this, we are also focusing on the functionalization of hydrophobic & hydrophilic polymer nanofibers surface by metallic nanoparticles and other functional groups.

Carbon Trading: Challenges and Perspective Natural calamities like floods, hurricanes, forest fire and drought are becoming the regular practice of happening all over the globe at different period of time. The latest one is the sandy which has made havoc in USA, the mightiest country of the world. With all the modern technology and information available, the humane being could not stop the happenings of hurricanes. There may be various reasons but definitely the degradation of environment may be one of the important reasons of such natural calamities. When the degradation of environment is considered, there are issues like local, regional and global which creates problems to environment. All these problems are important parameters for environment and concerned to everybody. But when the problems related to global scale is thought, it comes the global warming which is related to many other such problems. Global warming is nothing but average increase in the atmospheric temperature. Almost everybody knows about the effect of global warming on environment and human being. Global warming has created a new activity of trading the environmental services which basically termed as the carbon trading. This economic activity involve the buying and selling of services including the removal of greenhouse gases from the atmosphere. The element carbon is the common element in all the polluting gases which causes the global warming. Among all the greenhouse gases carbon dioxide is responsible for retaining about half of the atmospheric heat. It is known that this gas is generated primarily by burning the fossil fuel. The situation becomes worst due to deforestation along with the burning and biodegradation of biomass. The reports indicate that the concentration of carbon dioxide was 260 ppm during the pre-industrial period, but now the level is around 385 ppm. This increase in the level of carbon dioxide occurs in the last 100 years. It is also reported that in the year 2010 the emission was very high than the estimated emission. If suitable efforts are not put in this regard by the world community, then the level may reach 1000 ppm by the end of
Abundance is, in large part, an attitude.

current century. This situation will be very dangerous for the environment and the society. It may create havoc for the entire living creature on earth. What should be done? The solution lays in the conservation of energy, the reduction of consumption, a more equitable use of resources and equitable development and distribution of clean and renewable low impact energy sources, Than who will be doing all the above. It is definitely a herculean task and requires the involvement of everybody starting from a common man to the highest representative of the people. This cannot be done by a single or a group of country but by all the countries of the world. Back ground of Carbon Trading: After the Kyoto Protocol cane into force on 16th February 2005, the idea of carbon trading comes in to the focus. Subsequently the idea was more focused when 191 countries have signed and ratified the protocol in September 2011. As per the agreement of Kyoto protocol, the industrialized countries have to
reduce the emission of
greenhouse gas by 5.2 % lower than the level of 1990 between 2008-2012.The trading is almost similar to the trading of commodities or goods in a market place. An economic value is provided to the carbon which allows the people, companies or a nation to do trading. When anybody purchased the carbon, then he got the rights legally to burn it. Similarly, when somebody is selling the carbon, then he is giving up the rights to burn. And the value of carbon is based on the ability to store it or to prevent it from releasing to the environment. Trading facilities are created to provide the rights for buying and selling of the rights to emits greenhouse gases. The nation or company who has no means to reduce the emission, they can buy the rights to emit these gases from other nation or company who produces less amount of these gases or having technology to reduce the emission. This trading is possible as the Kyoto protocol provide the provision of reducing the emission of greenhouse gases as a collective responsibility. If this trading goes well than greenhouse gases will be reduced and some countries and companies will be benefited economically. There are many contradictory ideas being floated in support and against the
In theory, there is no difference between theory and practice.But in practice, there is. 25
idea. But the trading have its own merits but suggestion in various level should be incorporated from time to time as it require a compromise between profit, equality and ecology. International trends in carbon dioxide emissions: The emission of carbon dioxide is increasing continuously even after all the provision with all the old polluter along with some new one. The figure-1 provides an idea about the increasing trend of carbon dioxide. The two most populated developing countries of the world China and India have started increasing the emission due to the economic growth. This trend will further increase in future years. It is reported that there is an increase by 2.5 % annually in the level of CO 2 emissions and about two-thirds of this increase are from low and middleincome countries like India and China. The energy sector releases 80 % of the total emission and the rest 20 % credited to the agricultural sector. Coal is used as the main source of energy for electricity generation, The emission of few countries are presented in Figure-1: Recent global mean carbon dioxide

Kyoto Protocol: All countries are vulnerable to climate change but the poorest countries are worst sufferer as they have little means to adopt the changes. The Kyoto Protocol is a framework of United Nations Conference on Climate Change (UNFCCC) which has resolved to mitigate the climate change due to accumulation of more greenhouse gases in atmosphere. This is an international agreement, which legally binds, developed nation to reduce worldwide emissions of greenhouse gases. The Kyoto Protocol has come up with three clear cut mechanisms to reduce the targeted emission. They are called the Kyoto mechanism. The three mechanisms are 1. Joint Implementation 2. Clean Development mechanism and 3, Emission trading 1. Joint Implementation: This mechanism provide rights to a developed or rich countries to meet the Kyoto commitment by not directly reducing the targeted amount in their own country but applying the emission reducing project or by enhancing the removal by sink in the territory of another developing countries and can count this reduction as the reduction of that implementing countries.
I find that the harder I work, the more luck I seem to have.
27
2. Clean Development mechanism: As per the provision of this
mechanism
governments or any company from developed countries or any other countries can set up projects in any developing countries which reduces the emission and for that they get credit as certified emission reductions (CER's) The CDM provide sustainable development in developing countries, and earn emissions credits from the investments in the projects. The process flow of CDM projects are Complicated and actual which starts with. Project Design, Letter of Approval, Validation, Registration,, Implementation & Monitoring of Project performance, Verification and Certification of achieved emission reduction, Emission Reduction Certificates and Use under CDM 3, Emission trading: It provide provision to countries to involve in international emission trading. As per the provision, countries or company can go on trading by buying and selling of reduction emission certificates best on the cost of the projects. If the cost of reduction in one country is more than that countries can meet the target by purchasing the certificates where the cost is less. Carbon Trading: It is a system of trading in which a company or a country can meet the emission target by buying from another country or company who have the necessary certificates of reduction of emission. By doing so, a country or company allows to meet the carbon dioxide emission reduction target as per the requirement of Kyoto agreements. It is the trading of certificates representing different technique in which emission reduction targets may be fulfilled. The concerned parties can trade contractual commitments or a certificate which indicates that a fixed amount of carbon related emissions are allowed to be emitted or reduces the emission by using new technology, efficiency in energy consumption and renewable energy or by sequestration of carbon. This trading is going on as it is one of the ways of reducing the level of carbon dioxide emission with an assumption that the transaction cost involved in the trading are kept at reasonable rate. The process will be effective as the sellers have created a technique which reduces their own emission and obtained a certificate, and certainly it will be effective when it is purchased by

any other buyer. In fact there are two types of trading namely emission trading and project based credits trading .When both the trading are mixed than they are called hybrid trading. Prospective: If all the signatory countries will participate in the process definitely some reduction in emission will takes place. Some countries developing countries have adopted the process of trading. Many research groups throughout the globe are working for development of technology or process for the reduction of emission. If this process will be focused by the developed or reach nation this will give a good results. As this process is the trading of first environmental services in future similar services can be extended in other polluting substances Challenges: There are many challenges, among them the most important one is: the Kyoto protocol will be terminated this year but there is no common agreement by the member countries either extending the treaty or replacing the old one with a new one. The main reason is the conflict of interest between the developed and developing countries. But at the same time the challenges before the scientific communities is to create new technology or process to reduce the emission of greenhouse gases. We can hope to get a better future of environment and so city. This article is published to make awareness among the student to think and act to mitigate the increasing trend of global warming.

Chemistry and Computers: Friendship between Two “C”s After rejecting too many requests from our 2nd Yr. integrated M.Sc. student, Soumitra, I thought of writing for the first time in my life for our departmental magazine. In this write-up, in very few words I have focused how computers can be used as a tool to solve chemical problems. In my early days of Ph.D., I was totally unaware what computational chemistry belongs to. Later I came to know that it is possible to solve the chemical and physical problems using computers and the results can be correlated with the experimental findings. Surprisingly, for the first time I came to know that rather than mixing solutions in test-tubes it is also possible to mix them computationally. In broad sense computational chemistry is based on quantum and statistical mechanics and the terms popularly related to this area are theory, modelling and computation. All of us are comfortable with the term 'theory'. Next comes 'model' which is typically “involves the deliberate introduction of simplifying approximations into a more general theory so as to extend its practical utility.” The term 'computation' is the “use of digital technology to solve the mathematical equations defining a particular theory or model.” Computational chemistry relates not only in handling problems to chemical aspects but also in writing improved algorithm to solve difficult equations, developing new ways to visualize data etc. Another very well-known term in computational chemistry is “simulation”. The technique is popularly known as computer simulations. Simulation has dual role. It acts as 'connector' between theory and experiments. Because of such role the technique is known as 'computer experiments'. It provides a detail microscopic information of a system to macroscopic properties of experimental interests, e.g. the equation of states, transport co-efficients, order parameters etc. The information is not only of academic interest but also of technologically useful. In case of materials,

sometimes experimentalists find difficulties to carry out experiments at extreme pressure and temperature but a computer simulation of material, e.g. a high-temperature plasma, a nuclear reactor etc. are perfectly feasible. Besides, in case of molecules, experimentally it is difficult to probe fast ion conduction, enzyme action etc. but can be easily obtained from a computer simulation. In present days, in our daily life we can't think without computers. Similarly, modern advanced chemistry stops working without computers. Still people believe that chemistry is nothing but related to some reactions, mixing of solutions etc. but beyond their imagination there is some other way to explore chemistry. In this context I should mention that the Nobel Prize in Chemistry 1998 was divided equally between Walter Kohn "for his development of the density-functional theory" and John A. Pople "for his development of computational methods in quantum chemistry".

Use of Significant Figures (aka) Sig Fig in Chemistry This is what I mostly heard not only among the chemistry graduates but also to some extent among other graduates in our campus. Therefore, it is highly essential to train our students about the importance of sig figs in their calculations and measurements. Please remember that, in science, all numbers are based upon measurements (except for a very few that are defined). Since all measurements are uncertain, we must only use those numbers that are meaningful. Not all of the digits have meaning (significance) and, therefore, should not be written down. In science, only the numbers that have significance (derived from measurement) are written. The objectives of this write-up are: •
Explain the concept of significant figures.
•
Define rules for deciding the number of significant figures in a measured quantity.
•
Define rules for determining the number of significant figures in a number calculated as a result of a mathematical operation.
•
Explain rules for rounding numbers.
•
Present guidelines for using a calculator.
•
Provide some exercises to test your skill at significant figures. What is a "significant figure"? The number of significant figures in a result is simply the number of figures that are known with some degree of reliability. The number 13.2 is said to have 3 significant figures. The number 13.20 is said to have 4 significant figures. Rules for deciding the number of significant figures in a measured quantity:
He who has a 'why' to live, can bear with almost any 'how'.
63
(1) All nonzero digits are significant: 1.234 g has 4 significant figures. 1.2 g has 2 significant figures. (2) Zeroes between nonzero digits are significant: 1002 kg has 4 significant figures, 3.07 mL has 3 significant figures. (3) Leading zeros to the left of the first nonzero digits are not significant; such zeroes merely indicate the position of the decimal point: 0.001 oC has only 1 significant figure, 0.012 g has 2 significant figures. (4) Trailing zeroes that are also to the right of a decimal point in a number are significant: 0.0230 mL has 3 significant figures, 0.20 g has 2 significant figures. (5) When a number ends in zeroes that are not to the right of a decimal point, the zeroes are not necessarily significant: 190 miles may be 2 or 3 significant figures, 50,600 calories may be 3, 4, or 5 significant figures. The potential ambiguity in the last rule can be avoided by the use of standard exponential, or "scientific," notation. For example, depending on whether the number of significant figures is 3, 4, or 5, we would write 50,600 calories as: 5.06 Ă— 104 calories (3 significant figures) 5.060 Ă— 104 calories (4 significant figures) or
Talent does what it can; genius does what it must.
64
5.0600 Ă— 104 calories (5 significant figures). By writing a number in scientific notation, the number of significant figures is clearly indicated by the number of numerical figures in the 'digit' term as shown by these examples. This approach is a reasonable convention to follow. Rules for mathematical operations In carrying out calculations, the general rule is that the accuracy of a calculated result is limited by the least accurate measurement involved in the calculation. (1) In multiplication and division, the answer must contain the same number of significant figures as the term with the least number of significant figures. Example: (16.79) (14.6) = 245.134. The answers should be reported as 245.00. Why? Because the term with the least number of significant figures = 14.6 has only 3 significant figures. (2) In addition and subtraction, the answer must contain the same number of decimal places as the term with the least number of decimal places. Example: 18.02 12.2 328.445 358.665 Rules for rounding off numbers (1) If the digit to be dropped is greater than 5, the last retained digit is increased by one. For example, 12.6 is rounded to 13.
Against stupidity, the gods themselves contend in vain.
65
(2) If the digit to be dropped is less than 5, the last remaining digit is left as it is. For example, 12.4 is rounded to 12. (3) If the digit to be dropped is 5, and if any digit following it is not zero, the last remaining digit is increased by one. For example, 12.51 is rounded to 13. (4) If the digit to be dropped is 5 and is followed only by zeroes, the last remaining digit is increased by one if it is odd, but left as it is if even. For example, 11.5 is rounded to 12, 12.5 is rounded to 12. This rule means that if the digit to be dropped is 5 followed only by zeroes, the result is always rounded to the even digit. The rationale for this rule is to avoid bias in rounding: half of the time we round up, half the time we round down. -

Morning When the deep sun rays touches the earth, And the nature looks very fresh, With a foreword for the new race, Morning comes without a little trace. Butterflies with their coloring spray, Enjoy the warmth of falling ray. Kissing flowers once and once, Share their love in natural way. Morning wishes of the singing bird, Flowers wrapped in green and gold, Tiny dew drops on the glossy bed, Makes the heart deep and glad. The silence of city breaks with time. Again being busy when the clock is nine. The new morning is a lovely gift of God Comes hoping hatred to be replaced by love In the dreamt world. -

Chemistry- The King of Subjects An omnipotent, omnipresent and omniscient science Chemistry is one of the disciples of science which deals with the characteristics of substances and the changes they undergo when they are mixed with one another. It can also be defined as the science of matter and its transformation. Matter is made up of atoms and molecules. Hence, Chemistry is also well known as the science of atoms and molecules. Chemistry is involved in some way with almost everything we do or use. It is central to most of science and technology, blending at one extreme with Physics, Mathematics and engineering and at the other into the earth and lifesciences. So Chemistry in itself is a complete science which has several branches and each branch has its own importance and significance in diverse field. Understanding Chemistry helps us in knowing the world around us. From morning till night whatever we use are the products of Chemistry, the toothpaste in the early morning, medicines, petroleum products, food stuffs, fertilizers, preservatives and synthetic fibres are all golden products of Chemistry. Everything we touch, smell or hear is a chemical. Chemistry also provides answers to many questions which are related to our day to day life activities like Why laundry detergents work better in hot water? How baking soda works? Why not all pain-relievers work equally well on headache? Is this food fit for consumption? How can we develop new products from existing resources? Thus Chemistry is a blessing for we human beings to lead a more comfortable and luxurious life.
Confidence is contagious. So is lack of confidence.
68
Knowing all the above facts about Chemistry it can be easily concluded that Chemistry is the “King of subjects”. Beauty of Chemistry lives in its ability to simplify a seemingly terrifying complex universe, where everything is constantly changing on one time scale or another, into a few fundamental principles that enable us to understand, appreciate and change our world. Thus, “Chemistry is in the entire World and the entire World is in Chemistry”. -

The Periodic Table Expands Yet Again.... They exist for only seconds at most in real life, but they have gained immortality in chemistry: two new elements that have been added to the periodic table-Flerovium and Livermorium. They were earlier knwown by the temporary monikers ununquadium and ununhexium.The International Union of Pure and Applied Chemistry officially approved names for the elements – which sit at slot 114 (Flerovium) and 116 (Livermorium). Both elements are man-made, what used to be element 114 is now Flerovium, honoring the Flerov Laboratory of Nuclear Reactions in Dubna, Russia, where it was created. Element 116 is now Livermorium, for the Lawrence Livermore National Laboratory in Livermore, California, home of a scientific team that participated in its creation in Dubna. The chemical symbols are Fl and Lv respectively. The elements were created by smashing calcium ions (with 20 protons) into curium targets (which have 96 protons), combining to form element 116, Livermorium. This element decayed almost immediately into Flerovium, with 114 protons. In contrasts to more familiar elements like carbon, gold and tin, the new ones are short-lived. Atoms of 114 disintegrate within a few seconds, while 116 disappears in a fraction of a second. So, you won’t find these materials lying around. Once made, these atoms decay within seconds. -

The Improbable Reality The immediate assumption one has on hearing that an academic has won the Nobel Prize is that he must always have been a brilliant and hard-working individual who was marked out for golden success. It may be tough to believe buts it’s true. Sir John Gurdon, Nobel Prize in the year 2012 in psychology/ medicine winner was very weak at science..!! Gurdon attended Eton College, where he ranked last out of the 250 boys in his year group at biology, and was in the bottom set in every other science subject. A schoolmaster wrote a report stating "I believe he has ideas about becoming a scientist; on his present showing this is quite ridiculous. If he can’t learn simple biological facts he would have no chance of doing the work of a specialist, and it would be a sheer waste of time, both on his part, and of those who have to teach him.” Gurdon’s work was ‘far from satisfactory’. One effort ‘scored two marks out of a possible 50’. In a class of 18 at Eton College, this master placed Gurdon 18th. Some children could neither spell, nor write grammatically, or remember the books they had been studying, was greeted with howls of outrage and even cruel. The truth is that in state schools, proper school reports are a thing of the past. The old cliché — ‘could do better’ — is no longer allowed. It’s considered too harsh for the poor dears. But the fact is that unless someone tells a young pupil that they could do better, they never will do better. They are left with the lie that they could not improve even if they tried real hard. Indeed, many students receiving such a rebuke today would probably need counselling, or their parents would write off to a solicitor seeking redress. For his part, John Gurdon became a great scientist, not because he was a conceited, lazy boy, who thought he knew it all, when he did not. He became a great scientist when he stopped being that boy, and learned the tough lessons that his biology master wanted to teach him get your facts right, apply yourself, learn to be humble in respect of facts as well as to work hard.
That which does not kill us makes us stronger.
71
Sir John B Gurdon has won the Nobel Prize in Physiology or Medicine 2012 for his discovery at the University of Oxford that the specialization of cells is reversible, challenging the dogma that mature cells are irreversibly committed to their fate. He wins the award jointly with Shinya Yamanaka for the discovery that mature, specialized cells can be reprogrammed to become immature cells capable of developing into all tissues of the body. ”Their findings have revolutionized our understanding of how cells and organisms develop, said the Nobel Assembly at The Karolinska Institute in a press release while announcing the Nobel award”. Gurdon was made a Fellow of the Royal Society in 1971, and was knighted in 1995. In 2004, the Welcome Trust/Cancer Research UK Institute for Cell Biology and Cancer was renamed the Gurdon Institute in his honour. He has also received numerous awards, medals and honorary degrees. In 2005, he was elected as an Honorary Member of the American Association of Anatomists. He was awarded the 2009 Albert Lasker Basic Medical Research award. Gurdon's recent research has focused on elucidating the mechanisms involved in reprogramming the nucleus in transplantation experiments, including the role of histone variants, and DE methylation of the transplanted DNA. Gurdon later had the college report framed and he told a reporter, "When you have problems like an experiment doesn't work, which often happens, it's nice to remind yourself that perhaps after all you are not so good at this job and the schoolmaster may have been right." Speaking after learning of his award in London on Monday, Sir John revealed that his school report still sits above his desk at the Gurdon Institute in Cambridge, which is named in his honour. In the words of the great researcher Chris Graham “People had talked about cloning a good deal but with John Gurdon’s work it became a reality.” Thus the true flavour of character matters more than the grades on the sheet. -

Temporary Storage for Electrons In a HydrogenProducing Enzyme Scientists at the Max Plank Institute for Chemical energy Conversion (MPI CEC) and the Ruhr-Universidad Bochum (RUB) have found through spectroscopic investigations on a hydrogen- producing enzyme that the environment of the catalytic site acts as electron reservoir in the enzyme. Thus it can efficiently produce hydrogen, which has a great potential as a renewable energy so producing hydrogen with enzymes the system analyzed constitutes an enzyme that catalyzes the formation and conversion of hydrogen. In its center it has a double-iron core, and is therefore also called [FeFe] hydrogenase. Hydrogenases are of great interest for energy research, since they can efficiently produce hydrogen. However, new catalysts can only be developed given a deep understanding of their mode of action. In hydrogen production, two electrons get together with two protons. The research team showed that, as expected, the first electron is initially transferred to the iron centre of the enzyme. The second transfer on the other hand is to an Iron-Sulphur cluster that is located in the periphery. It thus forms a temporary storage for the second electron. This "super-reduced" state may be responsible for the extremely high efficiency of the hydrogenase. Subsequently both electrons are transferred in one step from the enzyme to the protons, so that hydrogen is generated. "Only the use of two different spectroscopic techniques made the discovery possible," says Agnieszka Adamska, a doctoral student at MPI CEC who carried out the spectroscopic studies source.

A Noble Discovery Here' a look at the most amazing award in the world. Yes, we are talking about THE NOBEL PRIZE. As you must know that it is given to the most intellectual and dedicated people in the field of physics, chemistry, physiology, medicine, literature and peace. And this time the pride of receiving this astonishing award for Chemistry has gone to Brian Kobilka (Stanford) and Robert Lefkowitz (Duke) for their work on the G-Protein-Coupled Receptors (GPCRs). So, let's make you explore the discovery made by them. GPCRs are proteins located in the plasma membrane. The name GPCR refers to a common mode of receptor signalling via GTP-binding proteins on the inside of the cell. So, they are essentially both the gatekeepers and molecular messengers of. The cell transmits signals from inside to outside. The GPCRs are also called seven-Trans membrane (7TM) receptors. This is because like every protein they have polypeptide chain, but their polypeptide chain passes seven times through the plasma membrane which is connected by three loops, three on the intracellular side and three on the extracellular side. In this way they span the cell membrane in the form of seven Trans-membrane helices. The six loops on a GPCR are: -
Particularly floppy and they also turn out to be particularly important determinants of molecular binding.
-
They act as a mediator, virtually for a wide range of physiological signals, from immune system function to taste and smell.
-
Response to the fight-or-flight situations in humans, which are coming from outside the cell.
-
The signal can be a change in concentration of peptides, hormones, lipids, neurotransmitters, ions, odorants, tastants, etc., or an influx of photons to the eye.
-
Reactions involving other proteins, nucleotides and metal ions, which eventually deliver a message and an appropriate.

Cellular and physiological response. The signal can consist of an amazing variety of stimuli, from photons (light) to Neurotransmitters to hormones. GPCRs can also exist in two states: an active state and an inactive state. Molecules that bind to these proteins come in three flavours: i) Agonists activate the receptor. ii) Inverse agonists completely shut it down. iii) Antagonists prevent agonist binding but don’t shut the protein down. A small molecule like a drug binds to one of the GPCR helices on the outside and these results in a complex series of motions of the helices that result in the dissociation of one of the G protein subunits. After dissociating, the G protein can interact with a variety of other proteins, including proteins called kinases which attach and detach phosphate groups and control cell signalling. The end result of this process is usually the activation of a so-called second messenger, a small molecule like cyclic. The GMP (cGMP) goes into the nucleus of the cell and brings about specific gene expression and attendant physiological responses. The binding of a small agonist molecule to the protein causes a crucial movement of the helices, resulting in interactions with intracellular G proteins and transmission of the external stimulus inside the cell. GPCRs are also immensely important in medicine and are the target of about 30% of all drugs. Naturally occurring small molecules which bind to GPCRs include adrenaline, prostaglandins, dopamine, somatostatin and adenosine. Drug-like small molecules which bind to GPCRs include caffeine, morphine, heroin and histamine.
If you can't explain it to a six year old, you don't understand it yourself.
75
This discovery has opened the way to not only a detailed dissection of the mechanism of GPCR function but also to structure-based drug design. In addition they have struck a blow to the belief that GPCRs cannot be crystallized. Most crystal structures of the GPCRs come with drugs attached to them and therefore they are invaluable starting points for designing more potent drugs with better safety profiles. The morphine-bound structures are particularly promising in this regard since finding a safe alternative to morphine has for decades been a kind of medical crusade with many corpses.

REALITY BEYOND IMAGINATION!!! Cholerophobia Town:While people in the town of Anderslöv, Sweden were suffering from a strange epidemic of green hair! People all over started complaining that their hair was turning green. When confronted with sudden hair changes, people are inclined to blame the drinking water. Environmental hygiene engineer Johan Pettersson. He and a team took samples of the local drinking water from several houses. They immediately suspected ample amount of copper, which turns thing green. Shiny bright new COPPER piping. When the water sat overnight in the pipes, and was then exposed to heat from the water heater for showers in the morning…hello green..!! Pettersson was incredibly proud to get Ig Noble Prize in 2012 in Chemistry for solving this mystery. And became a local HERO..!
Miscibly Immiscible We were always taught that oil and water can never mix. But recently it’s not true. Eric Adams, lecturer and senior research engineer in the Department of Civil and Environmental Engineering, and his co-investigators Scott Socolofsky and Stephen Masutani were awarded the 2010 Ig Nobel Prize in chemistry for disproving the adage that oil and water don’t mix. They demonstrated that most oil from a spill in the deep ocean, would in fact mix with water, rather than rise directly to the surface. The research for which Adams and his coinvestigators won the prize was part of the Deep Spill Joint Industry Project. In these tests, oil mixed with methane was released near the seafloor at a depth of 840 meters off the coast, and monitored with an array of instruments including remotely operated vehicles. The results demonstrated what Adams and Socolofsky’s laboratory experiments conducted earlier in the project had already shown. Rather than form a simple plume that would carry the oil directly to the surface, most of the oil would mix with seawater and stratify into

Test your taste..! Japanese researchers have succeeded in making the sweet smell of vanilla come out of the last thing people could imagine -- cow dung. In a world-first recycling project, a one-hour heating and pressuring process allows cow feces to produce vanillin, the main component of the vanilla-bean extract, according to researcher Mayu Yamamoto. The vanillin extracted from the feces could be used in products such as shampoo and aromatic candles but not in food, said Yamamoto, who works for the Research Institute of the state-run International Medical Center of Japan. Compared with usual vanilla, "this component is exactly the same but it would be difficult for people to accept it in food, given the recent rules of disclosing the origins of ingredients," she said. The production cost using dung is less than a half of making vanillin out of vanilla beans, she added. Yamamoto also awarded Ig Noble prize for this in 2007.
Swimming in syrup is as easy as in water. It's a question that has taxed generations of the finest minds in physics: do humans swim slower in syrup than in water? And since you asked, the answer's a big NO. Scientists have filled a swimming pool with a syrupy mixture and proved it. Edward Cussler and Gettelfinger got Ig Noble Prize in chemistry for this in the year 2005. He took more than 300 kilograms of guar gum, an edible thickening agent found in salad dressings, ice cream and shampoo, and dumped it into a 25-metre swimming pool, creating a gloopy liquid twice as thick as water. "It looked like snot," says Cussler. The pair then asked 16 volunteers, a mix of both competitive and recreational swimmers, to swim in a regular pool and in the guar syrup. Whatever strokes they used, the swimmers' times differed by no more than 4%, with neither

Statue that repelled pigeons: If you want your statues clean (and your pigeons healthy), you just need to make them of bronze laced with arsenic. In the Kenroku garden in the city of Kanazawa, Japan, stands a statue of the legendary hero Yamato Takeru no Mikoto. There are many things to admire about the statue, but as a scientist, Professor Hirose was fascinated by how pristine the figure is. Birds rarely visit it, and seldom bestow the kind of personal gifts they often lavish on statuary. Hirose analyzed a small sample of the metal. Its composition turns out to be unusual. The alloy contains copper and lead, which are not uncommon in statues – but also another element that seems very out of place. The statue's old bronze is laced with arsenic which repelled crows and pigeons. “When I gave my lecture, the audience were killing themselves laughing. I still don’t understand what’s funny about my investigation, “said Hirose when he was awarded the Ig Noble Prize for the invention of this amazing pigeon repellant alloy.

Hope That Makes A BIG Change In You The Professor began his class by holding up a glass with some water in it. He held it up for all to see & asked the students “How much do you think this glass weighs?”
’50gms!’….. ’100gms!’ …..’125 Gms’ …the students answered. “I really don’t know unless I weigh it,” said the professor, “but, my question is: What would happen if I held it up like this for a few minutes?”…. . ‘Nothing’ …..The students said. ‘Ok what would happen if I held it up like this for an hour?’ the professor asked. ‘Your arm would begin to ache’ said one of the students “You’re right, now what would happen if I held it for a day?” “Your arm could go numb; you might have severe muscle stress & paralysis & have to go to hospital for sure!” ….. Ventured another student & all the students laughed “Very good. But during all this, did the weight of the glass change?” Asked the professor. ‘No’…. Was the answer. “Then what caused the arm ache & the muscle stress?” The students were puzzled. “What should I do now to come out of pain?” asked professor again. “Put the glass down!” said one of the students
The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom. 83
“Exactly!” said the professor. Life’s problems are something like this.Hold it for a few minutes in your head & they seem OK. Think of them for a long time & they begin to ache. Hold it even longer & they begin to paralyze you. You will not be able to do anything. It’s important to think of the challenges or problems in your life, But EVEN MORE IMPORTANT is to ‘PUT THEM DOWN’ at the end of every day before you go to sleep… That way, you are not stressed, you wake up every day fresh &strong & can handle any issue, any challenge that comes your way! Moral So, when you start your day today, Remember friend to ‘PUT THE GLASS DOWN TODAY!’ -

Chocolate You guys must be wondering what this column on chocolate has to do with the chemistry dept. Magazine. Well to be true chocolate is one such consumable chemical that has got a beautiful chemistry about itself. Our world is filled up with chocolates all around and so now’s the time to take in a dip and indulge ourselves in knowing a bit more about it. The very word ‘chocolate’ almost has a magic about it and those who love it agree unanimously that the taste is quite definitely magical. The remarkable story of chocolate dates back to 7th century when the cocoa tree,’Theobroma Cacao’, was cultivated by the Maya civilization of Central America. This ancient civilization established a flourishing trade, even using the cocoa bean as a currency. The explorer Christopher Columbus took the cocoa bean to Spain in 1502, and Herman Cortes, who conquered Mexico for Spain, soon afterwards got an idea of what to do with this curious object when the Aztec emperor Montezuma introduced him to xocatlatl, a drink made of crushed, roasted cocoa beans and cold water. This bitter tasting brew soon evolved into something more pleasant when it was served hot with a flavouring of vanilla, spices, honey and sugar. By the late 17th century, Europe and beyond had fallen under the spell of the ‘Hot Chocolate’ drink. But it is a 19th century Dutch chemist, Coenraad Van Houten, whom we have to thank for chocolate that we can eat. This veritable hero invented a method of producing pure cocoa butter and a hard ’cake’ that could be milled to produce cocoa powder for flavouring. Within a very short time, the chocolate industry was founded, going from strength to strength as different countries began to produce smooth, melt in the mouth chocolate bars. Today to our delight-there is no end to the creative ways in which chocolate is used in cooking, puddings, cakes, biscuits, chilled desserts and ice-creams. They all seem to have extra appeal when they include chocolate.
Nothing is impossible, the word itself says 'I'm possible'!
85
If you are one of the world’s one of the many chocoholics, then after pondering over this article for the past five minutes you would want to make a fruitful use of your next upcoming five minutes by trying to grab one chocolate and indulge yourself in its beautiful feel.

Wake to Sleep I wake to sleep, and take my waking slow. I feel my fate in what I cannot fear. I learn by going where I have to go. We think by feeling. What is there to know..............? Waking (and sleeping) occurs under the influence of our brain’s circadian clock. The clock is called the suprachiasmatic nucleus. The nucleus is located in the hypothalamus, one on each side, deep in the brain, low behind the ear. By the shift from night to day and back to night as the earth turns. During sleep the brain energetically nixes consciousness and sensory perception .The thing about sleep, it’s involuntary. A person cannot will himself or herself to stay awake, even if life depends on it. For us mammals, sleep deprivation is torture, resulting in death if forced to continue. Sleep starts with non-Rapid Eye Movement. At first brain waves slow down, down, down until they arrive at Delta waves, long and slow. Heart rate slows, respiration slows, blood pressure sinks. But, dreaming, we are blind. Even when researchers open a sleeper’s eyelid and place objects in front of the eyeball, the dreamer cannot see. Sleep disorders such as sleepwalking are the dangerous syndromes in which the dreamer gets out of bed and bodily enacts the dream are brain disorders. Everyone dreams, even if everyone does not remember those dreams. During REM dreaming, the brain is more active than when awake. Neurons firing in the pons (located in the brainstem) set off REM sleep, during which the muscles are paralyzed: it is impossible to move. But the visual association areas and the limbic lobe—that seat of feeling—are active. So we have vivid dreams, at times full of feeling. Sleep turns us inward. It relieves us of cognizance and vigilance. Sleeping, we are deaf. But we may hear our being “dance from ear to ear.” -

The Chemistry of Love…… Ah, love. In the heady days of a mutual crush, pulses race, knees go weak, and heads reel. So strong are these feelings, they’ve launched a thousand songs and poems. When you say you and a romantic partner 'have chemistry' you're right! There is a lot of chemistry involved in feeling attachment, sweaty palms, butterflies in your stomach, etc. Have you ever wondered exactly what chemicals are involved in feeling love? Hormones converge for the people in love. We already know that falling in love is a bit like going crazy. Donatella Marazziti of the University of Pisa in Italy showed in 1999 that levels of the neurotransmitter serotonin, which has a calming effect, dip below normal in those who say they are in love as well as in people with obsessive compulsive disorder. Both groups spend inordinate amounts of time obsessing about something or someone. When we fall in love, dopamine is released, making couples feel elated and energetic about each other. "That someone takes on special meaning to you and you focus on this individual because the dopamine system has been activated," says Helen Fisher, PhD, a biological anthropologist. “It is what triggers very goal oriented behaviour, where no one else matters but your new partner.” Dopamine can be present in both early-stage and long-term romantic love Another possible ingredient in the love potion is norepinephrine. (It’s still being studied). This stress hormone increases the heart rate, and may be the reason you feel hot and flustered when that special person notices you. It also be responsible for that butterflies-in-your-stomach sensation. “It can cause that awkward feeling,” and the Sweaty palms, dry mouth as well as fumbling words. The major histocompatibility complex (MHC) is a set of genes that controls cellsurface molecules, which the body uses to tell self from foreign invaders. Our bodies exude MHC levels through sweat and body odour, as well as saliva. There are a wide variety of MHC types, but they tend to more closely match in people who are related. Based on scent and taste, studies suggest we can pick up on MHC levels in other people, and it’s thought that the more you differ in MHC, the
I find television very educating. Every time somebody turns on the set, I go into the other room and read a book.

stronger the attraction relationship-related obsessions aversion to particular numbers and nervous rituals. Although testosterone is thought of as a macho hormone, it helps stoke the fire in both sexes. Oxytocin is an essential chemical that calms and bonds couples together by promoting intimacy. Donatella Marazziti was awarded the Ig Noble Prize for the discovery that, biochemically, romantic love may be indistinguishable from having severe obsessive-compulsive disorder. Well, the next time we are with our romantic partner, it’s just more than the affectionate, caring and emotional feeling we have.

Award(1957)
also
made
foundational
contributions in the field of Chemistry, pioneering his career with the formula for the difference of any two hydrogen energy levels. Niels Henrik David Bohr, born in Copenhagen on October 7, 1885 grew up in an atmosphere most favorable to the development of his genius mind. His father, Christian Bohr, an eminent physiologist was responsible for boosting up his intellect. He joined the Copenhagen University after his matriculation, and under the guidance of Professor C Christiansen he took his Master's degree in physics in 1909 and Doctor's degree in 1911. In the year of 1911, he assisted Sir JJ Thompson and Professor Rutherford in their experimental work in the Cavendish laboratory at Manchester. His further analysis on the Rutherford theory of atomic nucleus made him successful in improving it. In 1913-1914, Bohr joined as a lecturer in Physics at Copenhagen University and later joined at Victoria University, Manchester. In 1916 he was appointed as the professor of Theoretical Physics at Copenhagen University and from 1920 until his death he served there as the head of Institute of Theoretical Physics. Earlier in 1912, Bohr married Margrethe Norlund. He laid the foundation for the very famous Quantum Theory. Niels Bohr proposed a model for the hydrogen atom where the negatively charged electron is attracted to the positively charged proton. Niels Bohr's greatest contribution to chemistry was, arguably, to be the first to develop a physics-based model of the atom. He explained that how spectral series emerge. When an atom is heated up, it begins to emit energy, but only at

particular frequencies. Bohr's activities in his Institute were more and more directed to research on the constitution of the atomic nuclei, and of their transmutations and disintegrations. He pointed out that in nuclear processes the smallness of the region in which interactions take place, as well as the strength of these interactions, justify the transition processes to be described more in a classical way than in the case of atoms. A liquid drop would, according to this view, give a very good picture of the nucleus. This so-called liquid droplet theory permitted the understanding of the mechanism of nuclear fission, when the splitting of uranium was discovered by Hahn and Strassmann, in 1939, and formed the basis of important theoretical studies in this field. In September 1943, Bohr entered upon a new venture, Manhattan project at Los Alamos Laboratory in New Mexico. In this project he was basically focused upon his social ethics regarding the 'nuclear arms race'. Thus, the intellectual legacy of this genius scientist was passed on after his death in 1962, in Copenhagen as a result of heart failure and was buried in Assistens Kirkegard in Copenhagen. Among Professor Bohr's numerous writings (some 115 publications), three appearing as books in the English language may be mentioned here as embodying his principal thoughts: The Theory of Spectra and Atomic Constitution, University Press, Cambridge, Atomic Theory and the Description of Nature, University Press, Cambridge, The Unity of Knowledge, Doubleday & Co., New York. Bohr was very much influenced by the works of Sir Albert Einstein and hence spent some of his years working with him. The discussions between Bohr and Einstein are famous all over and referred to as the Einstein-Bohr Debates. During the Nazi occupation of Denmark in World War II, Bohr escaped to Sweden and spent the last two years of the war in England and America, where he became associated with the Atomic Energy Project. Until the end, Bohr's mind remained alert as ever. During the last few years of his life he had shown keen interest in the new developments of molecular biology. The latest formulation of his thoughts on the problem of Life appeared in his final (unfinished) article, published after his death: "Licht und Leben-noch einmal", (in English: "Light and Life revisited").
