CHAIR’S MESSAGE
Dr. RICHARD DICKINSON CHAIR, DEPARTMENT OF CHEMICAL ENGINEERING
Greetings from Gainesville! As the 2015-16 academic year comes to a close, we wish hearty congratulations to our new Chemical Engineering BS, MS, and PhD graduates!
AS YOU KNOW, GATOR CHEME GRADUATES ARE HIGHLY SOUGHT AFTER from industr y and academia. The vast majority of our graduates already had job offers lined up by the time of graduation from outstanding companies around the nation such as Ex xonMobil, Dow, Kraft-Heinz, Intel and Michelin, as well as great Florida companies such as Anheuser-Busch, Tropicana and Johnson & Johnson Vision Care. Several of our new graduate school bound students ended up at top Chemical Engineering PhD programs, including Caltech, University of Minnesota, University of Texas-Austin and the University of Michigan. I was privileged to conduct exit interviews with all 116 spring B.S. graduates, and ever y class is even more impressive than the last. What do students appreciate most about our program? The excellent, caring faculty and the camaraderie and friendships they enjoyed with their fellow students—something they will always carr y with them into the future as part of the greater Gator Nation. These are exciting times for Gator engineering! The College received a ver y generous gift of $50 million from the Herbert Wertheim family, which will lead a $300 million investment into the newly named Herbert Wertheim College of Engineering. The Wertheim transformation will lead a new building, state-of-the-art new facilities and several new faculty positions. Among these, we anticipate growth of Chemical Engineering from 21 currently to 25 faculty in the next few years. In particular, we will build on our research strengths in chemical energy systems, bioengineering, nanotechnology and multiphase fluid dynamics. Our faculty continue to be leaders in their research fields, generating high-profile research publications this year in prestigious journals such as Advanced Materials, Angewante Chemie, and the Proceedings of the National Academy of Science.
Our success is supported largely by the tremendous financial support from the friends, faculty and alumni of Gator Chemical Engineering. In the last four years, bequests, commitments and cash gifts have exceeded a remarkable $11 million, ensuring a ver y bright future for Gator Chemical Engineering! We now have seven endowed faculty positions in the department, up from two only a few years ago. Endowed faculty positions honor and help support the research and education activities of those faculty who bring great prestige to our department and have the greatest positive impact on our reputation and on the students. The most recent endowed position is the Dinesh O. Shah Distinguished Faculty Fellow in Surface Science, which was awarded to Professor Anuj Chauhan. Congratulations, Anuj! Our graduate program now enjoys two annual endowed lectureships, one in Fluid Mechanics on the Dinesh O. Shah Lectureship in Surface Science. These serve to honor and bring to campus the most distinguished researchers in these respective research areas.
WE HOPE TO SEE YOU NEX T FALL AT HOMECOMING OR OTHER ALUMNI EVENTS. IF YOU ARE IN SAN FR ANCISCO AT THE ANNUAL AICHE MEETING, PLEASE STOP BY AND VISIT US AT OUR ANNUAL DESSERT AND COCKTAIL RECEPTION ON TUESDAY, NOVEMBER 15TH. 2 Powering The New Engineer

PAPERS & PUBLICATIONS
RESEARCH FEATURED AS A FRONTISPIECE OF ANGEWANDTE CHEMIE Research performed as collaboration between Professors Helena Hagelin-Weaver in Chemical Engineering and Clifford Russell Bowers in Chemistry has been featured as a frontispiece in a recent issue of Angewandte Chemie. In this work, the hydrogenation of propene to propane was investigated over CeO2 nanocubes, nanorods and nano-octahedra using parahydrogen induced polarization (PHIP) nuclear magnetic resonance (NMR). PHIP-NMR is a unique method which can identif y if the two hydrogen atoms added across the double-bond of propene originate from the same molecule (pair-wise addition of hydrogen) or is the result of random addition, and can thus give insight into the mechanism of hydrogenation reactions. The highlighted research reveals that while the hydrogenation of propene over CeO2 is strongly dependent on the CeO2 surface structure (and thus also CeO2 shape), the pair-wise addition of hydrogen is not. This research collaboration has also resulted in the JACS paper below.
JOURNAL OF THE AMERICAN CHEMICAL SOCIET Y PAPER ON ALKENE HYDROGENATION In a recent paper published in Journal of the American Chemical Society, Professors Helena Hagelin-Weaver (Chemical Engineering) and Clifford Russell Bowers (Chemistry) investigated the hydrogenation of propene to propane over titania-supported platinum (Pt/TiO2) catalysts using parahydrogen induced polarization (PHIP) nuclear magnetic resonance (NMR). Using PHIP-NMR, a small amount of propane product resulting from the pair-wise addition of hydrogen over the supported metal catalyst was observed. Furthermore, PHIP signal was observed also on the propene reactant. It was shown that this is the result of a previously hidden pathway of pairwise replacement, i.e. dehydrogenation and pairwise rehydrogenation, over this catalyst.
RECENT PAPER FEATURED AS HIGHLIGHT AND COVER ART OF JOURNAL OF CELLUL AR PHYSIOLOGY Research performed by Qiao Zhang and his coworkers was recently selected to be a highlight article and cover art by the Journal of Cellular Physiology. Despite being densely packed with DNA, nuclear bodies and a nucleoskeletal network, the nucleus is a remarkably dynamic organelle. Chromatin loops form and relax, RNA transcripts and transcription factors move diffusively, and nuclear bodies move. Zhang’s work shows a new type of motion of RNA splicing speckles in the cell nucleus. Small speckles move to larger speckles with which they fuse in an ATP and RNA polymerase II dependent manner. The random motion of speckles is regulated by both intra- and extra-nuclear forces. Qiao and his coworkers also devised a novel method to create a pressure gradient flow inside the nucleus. Speckles moved and deformed along curvilinear paths in respond to the pressure flow, suggesting the presence of channels with a low mechanical resistance to motion through which the speckles can move.
SMART SHAPE MEMORY POLYMERS PUBLISHED IN NATURE COMMUNICATIONS Shape memory polymers are a class of smart materials that can memorize and recover their permanent shape in response to an external stimulus, such as heat, light, and solvent. They have been utilized in a wide spectrum of applications ranging from biomedical devices to aerospace morphing structures. Led by a Chemical Engineering graduate student Yin Fang, Prof. Jiang’s group has recently pioneered a new type of shape memory polymer that can be instantaneously triggered by applying an external pressure or by exposing to a large variety of vapors, such as acetone and toluene. These unconventional stimuli induce an easily perceived color change of the special polymer. This striking chromogenic effect could find important applications in reconfigurable/rewritable nanooptical devices for all-optical integrated circuits, reusable and inexpensive chromogenic vapors sensors for homeland security and environmental monitoring (e.g., detecting explosives and toxic vapors in buildings), novel biometric and anti-counterfeiting materials, and healthcare screening. The results have recently been published in Nature Communications (doi: 10.1038/ncomms8416) and Advanced Materials (doi: 10.1002/adma.201500835). Dr. Curtis Taylor from UF Department of Mechanical and Aerospace Engineering and Dr. Vito Basile from National Council of Research, Italy are major collaborators of the work. DTRA, NASA, and NSF sponsored this discovery.

CHEMICAL COMMUNICATIONS PAPER ABOUT CO-SURFACTANT STATES AROUND CARBON NANOTUBES Research performed by Chemical Engineering Ph.D. student, Yang Zhao, under the advisement of Dr. Kirk Ziegler was recently published in Chemical Communications. Single wall carbon nanotubes (SWCNTs) contain a mixture of nanotubes with different chiralities known as (n,m) types. This work reports the formation of thermodynamic co-surfactant states around SWCNTs. The stability of these thermodynamic states enables high-fidelity separations of specific SWCNT (n,m) types based on their selective desorption from hydrogels. By modulating the surfactant concentration of sodium dodecyl sulfate (SDS) and sodium deoxycholate (DOC), the Ziegler group found a very specific co-surfactant ratio that elutes a high-purity (90%+) fraction of (6,5) SWCNTs. The elution of only one (n,m) type at a specific co-surfactant ratio while other types are exposed to more surfactant suggests that each (n,m) type forms a thermodynamically-stable structure in the co-surfactant solution. These findings provide a promising foundation for the development of large-scale, high-throughput chromatographic separations that can collect each (n,m) type sequentially. This work was performed in collaboration with the Dr. Jean-Claude Bonzongo group (Environmental Eng. Sciences Department, UF).
RESEARCH FEATURED AS A FRONTISPIECE OF ADVANCED OPTICAL MATERIALS The research conducted by a Chemical Engineering graduate student, Yin Fang, with Professors Jiang and Taylor (UF Aerospace and Mechanical Engineering) was featured as a frontispiece in the recent issue of Advanced Optical Materials. This work explores a new type of smart nanooptical coatings with bistable optical states using thermoresponsive shape memory polymers. The heat-triggered transition between a disordered temporary state and a 3-D ordered permanent state leads to an easily perceived color change, which provides a unique mechanism for developing reconfigurable nanooptical devices for all-optical integrated circuits.
PAPER CHOSEN AS EDITOR’S PICK IN JVST B The “Elevated Temperature Performance of Si-implanted Solar-Blind beta-Ga 2 O 3 Photodetectors” Paper by Professors Fan Ren and Stephen Pearton et al has recently been selected as Editor’s pick in the Journal of Vacuum Science & Technology B. High temperature (up to 350ºC) performance of planar, solar-blind β-Ga 2 O 3 photodetectors fabricated on thin films were investigated. There is strong interest in the development of deep ultraviolet (UV) photodetectors that exhibit cut-off wavelengths of 280 nm or below and are therefore solar-blind, enabling detection of UV wavelengths in military applications and flame sensing in the presence of the solar radiation that can penetrate the Earth’s atmosphere. There are a number of wide bandgap semiconductor materials systems that are potentially suitable for these applications, including the high Al-content AlGaN alloys, BN, SiC, diamond, ZnSe, ZnS and ZnMgO. All of these have shown promising and even excellent results in some cases, but all have some limitations, such as the persistent photoconductivity in AlGaN, the indirect gap of SiC, the environmental sensitivity of ZnO-based materials and the cost, lack of availability of high quality films/substrates and lack of doping technology for some of the other materials.
ANGEWANDTE CHEMIE PAPER ABOUT ALK ANE ACTIVATION The Weaver group recently published a paper in Angewandte Chemie that reports the first vibrational spectra of a “pre-activated” alkane adsorbed on a solid surface. A strong interaction between propane and the metal atoms of a palladium oxide surface causes the activated C-H bonds to undergo a large downshift in their stretching frequencies which the Weaver group could measure using surface infrared spectroscopy. By using partially deuterated propane compounds, Weaver and his students were able to show that the adsorbed propane molecules adopt highly specific configurations in which the primary C-H bonds are selectively activated by the metal oxide. Their work demonstrates that geometrical registry between the molecules and the surface plays a decisive role in determining the preferred bonding configurations of alkanes adsorbed on metal oxides. These findings can provide guidance to future efforts aimed at designing catalyst structures with potential to achieve selective alkane conversions.

STUDENT NEWS & AWARDS
Italian Technology Award in Packaging Josh Diblin ChemE Undergrad, Minor in Packaging ChemE Packaging Engineering student, Joshua Diblin, has been awarded an Italian Technology Award in Packaging, which includes an all-expenses paid trip to Italy. The Italian Trade Agency (ITA), in partnership with UCIMA (the Italian Packaging Machinery Manufacturers Association) developed this award for a group of US students and professors to gain firsthand knowledge of Italian machinery and technology for the machinery manufacturing in packaging. This opportunity is provided through the “Italian Technology Awards” (ITA) – Packaging Sector program—an essay writing competition for packaging students at selected academic institutions organized by the ITC and UCIMA. The Italian Trade Agency-ICE is the Government agency that supports the globalization of Italian firms, implementing the strategies of the Ministry of Economic Development. Italy has long been recognized as an industry leader in the packaging sector, and is known for its innovation and flexibility. The Italian packaging machinery industry is noted for holding significant global market shares—Italian packaging machinery manufacturers provide one of every four machines worldwide. Most of the packaging machinery produced is absorbed by the food sector (which accounts for around 60% of the industry’s sales) and pharmaceuticals, cosmetics and toiletries (just under 25%). The remaining is targeted toward other sectors, particularly tobacco, where the Italian machinery industry has a long tradition, chemicals/petrochemicals and tissue. Josh is on his second packaging engineering co-op (Kraft and Wrigley’s), is from Gainesville and attended St. Francis Catholic High School.
At the 2015 MRS Fall meeting in Boston, graduate student Yin Fang won the Silver MRS Graduate Student Award for his talk on novel multi-stimuli-responsive shape memory polymers. Yin is the second UF recipient of this prestigious award in the past 14 years.
