Editorial Singular, incredible, unforgettable. After almost 100 years, this was the first time South America hosted the IUPAC World Chemistry Congress. Around 700 scientific activities were held, incorporating all areas of chemistry, with the participation of more than 3,500 people from 66 countries around the world. Among several innovations, we introduced a ground-breaking 360° stage system that captivated the participants. With up to 8 conferences taking place simultaneously in a single space, without separate rooms or dividing walls, the audience managed to watch one or more activities without having to move around. At such a special moment, during the 40-year anniversary celebrations of the SBQ, we were the world capital of Chemistry. It is impossible not to be overwhelmed when recalling the extraordinary conference of current Nobel Prize winner Sir Fraser Stoddart who, with his eyes welling up and his voice breaking, described the fascinating world of nano-machines and demonstrated some of the determining factors in achieving personal and professional success. Among those present, the atmosphere was of pure harmony and euphoria. In their smiles and enthusiastic participation, their pride of hosting the most global event of the Chemical Sciences was palpable. Together we have built a beautiful history, which fills us with joy and has made these last 7 years of dedication and work all worthwhile. Brazil and South America already have their places guaranteed on the world map of Chemistry. IUPAC-2017 is leaving us with a tangible legacy, which should be in favor of our society, our researchers, professors and, especially, our young students, who represent our future. Congratulations to the SBQ and to all who have helped us make this dream come true! Adriano D. Andricopulo Rossimiriam Pereira de Freitas
Globalized Chemistry Rajesh Pandit was the sole representative from Nepal at the World Chemistry Congress. He is a physicist and chemist who specializes in polymers and is the deputy head of the Tri-Chandra campus of Tribhuvan University in Kathmandu, as well as being a director of the Nepalese Polymer Institute. “Our chemistry course is 50 years old and the university attracts 3,000 students to our science and technology courses each year”, Pandit said. “We are developing the research and science environment in Nepal.”

The Science, Life and Charisma of Sir Fraser Stoddart Nobel Prize winner for Chemistry in 2016 tells us about his nano-machines and is treated like a popstar, taking hundreds of selfies and signing autographs
If IUPAC-2017 brought the cream of the crop of world chemistry to Brazil, the event will have left nothing but good memories for Scotsman Sir Fraser Stoddart, winner of the 2016 Nobel Prize in Chemistry. The afternoon after his conference, Sir Fraser spent around three hours taking photos and signing autographs, receiving the full popstar treatment from the young and enthusiastic crowd. “I’m overwhelmed, this is the first time this has happened in my life”, he said, between autographs. “I wasn’t aware of his work, and it was great to learn about it. Besides the scientific aspects, he also showed his humble, human side and came here to be closer to us”, remarked Helena Mannochio Russo, who is taking a Master’s Degree in natural product chemistry and was taking part in an SBQ event for the first time. Sir Fraser had already tugged on the audience’s heartstrings that morning, when he was visibly moved during his conference, speaking about love, family,
freedom, politics, creativity, art and chemistry. A chemistry so advanced – his nano-machines based on mechanical bonds – that he compared it to aviation in 1927. “The Nobel Prize was an acknowledgment of the basic research. Before Charles Lindbergh flew across the Atlantic we didn’t know where aviation could take us. Today we know that mechanical bonds will change the world, but we have no idea about the different applications which will come from them, besides the most obvious ones such as in medicine and in the information technology industry.” In 1991, the researcher managed to thread a molecular ring onto a molecular axle and then demonstrated he was able to control the movement of the ring along the axle, thus establishing a whole new field of chemistry. He has published more than 1,200 papers and trained over 400 PhD students and postdoctoral researchers. An only child, he was raised on a farm close to the city of Edinburgh “without electricity until 18 years old, with lots of love and
46th WOrlD CHemIsTry COnGress
support from parents, rewards for effort and a great incentive to the risk of discoveries.” He encouraged researchers to persevere with their ideas, even in the face of criticism or a lack of attention from the scientific community. “Those on the outside do not have the answers you are searching for. I’ll repeat something I was told by one of my teachers: find a large problem and pursue your solution”, he advised. By quoting a paper by Jean-Pierre Sauvage (his Nobel laureate colleague in 2016, along with Bernard Feringa), he encouraged chemists to publish good papers in Portuguese. “Good papers will be read and they will make an impact, regardless of which language they are written in. Try it in Portuguese.” The 46th World Chemistry Congress also included conferences from Nobel Prize winners Robert Huber (1988) and Ada Yonath (2009).
Religion and Nationalism are Two Albatrosses of Humanity At a time in which social conflicts are being exacerbated across all continents, and nationalist and religious leaders are emerging in politics, Sir Fraser Stoddart left us with a warning. “Religion and nationalism are the two biggest albatrosses of humanity, which will be very hard to free ourselves from”, he told to SBQ, commenting upon Albert Einstein’s famous aphorism from his essay “On Science and Religion”: “Science without religion is lame, religion without science is blind.” “I think that over the course of time, human beings will be able to answer the questions about where they
came from and what they should be striving for, and I don’t think that religion will show this path, as they take shortcuts for explanations which are bizarre”, he observed. “If we didn’t have religion and nationalism in our lives, we would be going into a much more peaceful era. We are still paying the price for an ancient religious conflict with many wars.” Active on Twitter, where he defines himself as someone who “mingles art with science”, Sir Fraser expressed his dismay on social media at the walls and barriers that separated the business class passengers on his flight to São Paulo. “We need to break down the barriers that keep people apart. The very notion of countries does not fit into an ideal world”, said the Nobel laureate. The researcher defends the importance of a minimal scientific knowledge for all citizens in order to improve the development of society. “I think we need to re-evaluate our notion of democracy. If it means that people with increasingly distinct levels of knowledge have the same representation in the polling booth, then I think it doesn’t work. Perhaps it would be a case of evaluating whether citizens require a minimal level of knowledge before they can vote. See what happened recently in the United States and the United Kingdom (the victory of Donald Trump and Brexit). These decisions were very harmful to these populations”, he opined. On his part, Sir Fraser says he has done the best he can in regard to communicating with people from different countries, in particular, young people. “I’m happy to be on Twitter and see that people are interested in knowing what I have to say.”

SBQ Announces Foz do Iguaçu 2018 and Increase in Publications The success of the 46th World Chemistry Congress was an unforgettable 40th anniversary present for the SBQ. With more members than last year, their accounts approved, praise from the IUPAC board about the event and the certainty that Brazilian chemistry has been taken to another level, they now have the challenge to hold the 41st Annual Meeting in Foz do Iguaçu in 2018. “The 40 years of the SBQ had its high point with the conference of Sir Fraser Stoddart. It has been a while since we have had a current Nobel Prize winner with us, and his empathy with the audience was sensational. We have reached the peak of our internationalization, we are on top and we can’t let this fall”, declared the president of the SBQ, professor Aldo Zarbin. Norberto Peporine Lopes, Zarbin’s successor as of May 2018, highlighted the presence of young people and women at the event. “This was remarkable. The IUPAC board were impressed with the motivation of the young people
of Brazil”, he stated during the organization’s ordinary general assembly. The secretary general of the SBQ , professor Rossimiriam Freitas (UFMG), presented figures from the event and announced Foz do Iguaçu as the host for the next Annual Meeting, scheduled for May 20 to 24, 2018. “The positive feedback from the participants was incredible, everyone was very enthusiastic. All of us who have actively participated in the organization of this grand event are very happy with the results. Myself in particular, as I was in direct contact with hundreds of the participants during the organization phase”, she declared. Professor Luiz Henrique Catalani highlighted the internationalization and also the significant presence of the chemical industry (who held a symposium and a seminar) at the event. “It is a partnership which has been built with more enthusiasm in the last four years, and one which we must foster”, he stated.

The board of directors praised the work of the previous boards who laid the path for IUPAC 2017 to be held in Brazil. The idea appeared and was developed during the administration of César Zucco, the hosting bid was made official during the administration of Victor Ferreira, Brazil was awarded the event during the administration of Adriano D. Andricopulo and was then organized by the current administration. “We must also mention professor Fernando Galembeck, one of the first people from the SBQ to make contact with IUPAC”, stressed professor Vanderlan Bolzani, Brazil’s representative at IUPAC. In a year of economic crisis, the Assembly celebrated the fact the World Chemistry Congress resulted in profit, the result of the large coordinated effort of the organizers. The organization’s balance sheets showed an increase in revenue from new memberships and publications, which are becoming even more important in the funding of SBQ activities. “Our members realized the importance of being part of a strong and representative scientific community such as our own, as well as submitting papers to our publications”, highlighted Zarbin.
SBQ Board of Directors
The Importance of Presenting Papers The 40th Annual Meeting of the SBQ, held during the World Chemistry Congress, highlighted the value of the traditional coordinated sessions of scientific divisions. In total there were 12 sessions with 96 presentations from undergraduate and post-graduate students, as well as researchers, held on the same day as the conference of Nobel Prize winner Sir J. Fraser Stoddart. The papers were selected by the members of the SBQ. Giulia Murbach de Oliveira, 20 years old and attending her third year of an undergraduate course at the Federal University of São Paulo (Unifesp), was ready to present her paper about the diffusion of ionic liquid in charged clefts, during the poster session. She had been preparing for a long time for her first large scientific event when she received a surprise invite from the SBQ to present her work at the Physics-Chemistry/Theoretical Chemistry coordinated session. “It was a surprise because I never thought I would be chosen”, she said. “I’m very critical [of my own work] and I got a bit agitated during the presentation, but my colleagues told me I did well. It was a really gratifying experience.” Giulia said she had studied the diffusion of ionic liquids for around a year with her professor, José Leonardo Amaral de Siqueira. “It is a work which aims to study the efficiency of different materials for use in supra-capacitators. In practice we are talking about better ways to store energy”, she explained. The 40th anniversary of the SBQ also held special significance for chemist Danilo Pereira de Sant’ana, who

graduated from UFRJ, with a PhD from Unicamp and post-doctoral research in Berkeley. His work was chosen for the World Chemistry Congress’ organic synthesis symposium. “It’s a fantastic experience. While there is a certain apprehension in presenting to the international community, in English, it’s really gratifying to have my work chosen out of so many others”, he said. He is a member of the SBQ since his graduation and considers the scientific meeting incredibly important in the career of all chemists. “It was at an Annual Meeting where I met my post-doctoral supervisor. Meeting other chemists from around Brazil and abroad is an opportunity everyone should make use of.”

DISCUSSION PANEL
IN SEARCH OF A SUSTAINABLE PLANET The world is changing. Resources are showing signs that they are running out and, more importantly, society has begun to understand that this is a problem. Chemistry is a key player in this search for solutions. This was the overbearing message of the first panel of the 46th IUPAC World Chemistry Congress, where representatives from industry and chemical societies from seven countries debated the future of chemistry. “Twenty years ago, the understanding was that climate change did not exist”, said IUPAC president, professor Natalia Tarasova. “Ten years later, we understood that there was a problem, but that we weren’t a part of it. Today we are fully experiencing these changes, but it is too late to stop them.” Tarasova mentioned the United Nations sustainable development goals. Zero hunger, clean water and sanitation, and responsible consumption and production are some of these goals – “and chemistry is present in all of these”, she pointed out. “These are global problems, for which we also need a global approach”, said professor Aldo Zarbin (UFPR), president of the Brazilian Chemical Society (SBQ). Zarbin spoke about the internationalization of the scientific community – “cultural diversity is just as important as diversity in the subjects being researched”, he said. According to Zarbin, 30% of scientists work outside of their home country and since 2015 there have been 25% more papers authored by researchers of different nationalities. Diversity was another matter which was extensively addressed. “Diversity brings innovation”, said John Biggs, P&D director of Dow in Latin America, who represented the Brazilian Chemical Industry Association (Abiquim). According to him, the search for individuals of different genders, ethnicities and sexual orientations is heavily emphasized in all large companies in the sector. Ingrid Montes, director of the American Chemical Society (ACS), presented figures which show that the participation of women in science is still low.
“Sustainable chemistry depends on talent, and we have to attract young people if we want to guarantee to have the talent of the future. Science is changing, we have to change education too.” – John Holman, Royal Chemical Society “The proportion of men to women in the world is 1 to 1, but in science, 74% are men”, she said. Of the patents registered in the United States, 93% belong to men, and at the leadership positions in companies, female representation is also restricted – out of senior professionals, only 9% of CEOs are women. Also took part in the panel Thisbe Lindhorst, president of the German Chemical Society, Zhigang Shuai, general secretary of the Chinese Chemical Society, Sir John Holman, president of the Royal Chemical Society, and Richard Hartshorn, general secretary of IUPAC. The panel was coordinated by professor Paulo Cezar Vieira (UFSCAR), former president of the SBQ.

IUPAC General Assembly
Montreal Is
Chosen For 2021
In 2019, in Paris, around 8,000 chemists are expected to attend
The hospitality and the vivacity of the young students are some of the things the members of IUPAC and the attendees from 66 different countries will take with them from their six days in São Paulo during the 46th World Chemistry Congress. “There was a certain skepticism when Brazil made their candidature (to host the event)”, said Natalia Tarasova, president of IUPAC. It was the first time the country had appeared among the list of hosts, the mood was uncertain and the location was very far from the Europe-North America axis where most of the meetings take place. “But we are really satisfied. The organization was perfect, carried out with a lot of effort and skill”, she noted. Now, work begins in preparing for future editions. The IUPAC General Assembly always takes place parallel to the congress, bringing together the leadership of the association with a view to planning their guidelines for the next few years. The future president, council and committee members are all chosen during the assembly, as well as the host cities of future congresses. Canada was chosen to host the 2021 edition, given the responsibility of holding the largest chemistry event in the world in the city of Montreal. “We’ve hosted the event twice already, in 1981 and 2003 in Vancouver and Ottawa”, said Neil Burford, director of the Canadian Society of Chemistry (CSC) and Canada’s representative in IUPAC. The Canadians were up against China, Thailand and Israel for the right to host the 2021 congress. The Hague was chosen as the host city for 2023, overcoming four other candidate countries. Just like Brazil, the Netherlands will host the world congress for the first time in their history. It is estimated that from the preparation of the bid to the event itself, six years of work are required, including financial analyses, drawing up a scientific agenda, sending invites and registrations, accommodation,
adapting infrastructure, number of rooms, access routes and a dozen other responsibilities closely watched over by IUPAC. Burford said that only preparing Canada’s candidature took three years’ work: “It’s a great privilege for us, as we greatly value international collaboration and IUPAC is the best stage for this”, he said. Since 2013 it has been decided that Paris will host the 2019 edition of the congress, as it was there in 1919 that the IUPAC was founded. “It’s our centenary year”, highlighted Lynn Soby, executive director of IUPAC. “And it will be completely atypical. While we usually count on having around 3,000 participants, in Paris we will have around 8,000.”
Christopher Brett Enters the Line of Succession Another important decision made at the 2017 IUPAC General Assembly in São Paulo was the election of the organization’s future president. Christopher Brett, a British chemist based in Portugal, was chosen for the role. Emeritus professor of the Chemistry Department of the University of Coimbra, Brett will take over the vice-presidency for the biennium of 2019-2020, and will then assume the presidency in 2021 and 2022. This is because IUPAC has a very particular way of defining its board. Presidents are first elected to a two-year term as vice-presidents, then automatically stepping up to the presidency. On January 1, 2018, vicepresident Qi-Feng Zhou of China will take over from the current president, Natalia Tarasova. “I understand that, when we are young, we receive a lot of support from the chemistry community”, said Brett, about what this new role means to him. “When we get older, it becomes our turn to help the community.”

Heavy Metals Ratified This year, the IUPAC general assembly had another extraordinary task: ratifying the addition of four new elements to the periodic table. “It is a process that takes between six and seven years, or even longer, from the moment the discovery is claimed”, said the executive director of IUPAC, Lynn Soby. Once a group of researchers believes they have discovered a new element, they must first notify IUPAC and wait for evaluation. The discovery then needs to be published and revised by the world’s leading scientific journals. The evaluation is long, careful and led by an extensive team of scientists who are not only connected to chemistry, but also to physics. “The first frenzy is announcing the discovery. Then there is the frenzy of choosing names”, says Soby. The laboratories responsible for the discovery get to suggest the name and the two-letter symbol to denote the element, by way of a process which is also open to collaboration from society. Approved in December 2016, the new elements, discovered by researchers from the United States, Russia and Japan, have been named nihonium (Nh), moscovine (Mc), tennessine (Ts) and oganesson (Og), respectively occupying positions 113, 115, 117 and 118 of the periodic table. All are part of the so-called “heavy metals” group, which are isotopes created artificially by bombarding atoms and which last for few seconds before dissipating. It is worth noting that this is the first time in history four elements have been named at the same time and the confirmation was made in Brazil, a gift for the 40 years of the Brazilian Chemical Society.
