Of course, he also looks forward to reminiscing about the great times he had here as a graduate student, spending late nights and early mornings with punch cards at the computing center, and when he met his wife Karen and got married. Karen will be joining him during his sabbatical.

Geoff D. Moggridge will join the department in November as a Piercy Professor. Dr. Moggridge has been a lecturer since 1995 at the University of Cambridge in the Department of Chemical Engineering.

His research interest is in the area of structured materials, specifically detergent structure, anatase precipitation, carbon adsorbents, silver bullets for Zebra mussels and chemical product design. There are two areas of research he would like to develop during his time in Minnesota. The first is barrier membranes work in collaboration with Professor Ed Cussler. The applications he has in mind are oxygen barriers for polymer electronics, odor barriers, and a water-soluble water barrier for detergents. He is interested in producing reactive barrier membranes using equilibrium reactions, perhaps including adsorbents such as carbon. The second area is to explore the possibility of using diblock copolymers as precursors for controlled pore size mesoporous materials in collaboration with Marc Hillmyer (Chemistry) and Frank Bates. He has done some preliminary experiments in Cambridge using diblock samples prepared in Minnesota and the use for ozonolysis looks promising. He also hopes to make some useful contacts for his zebra mussel project while residing in the Great Lakes/Mississippi area.

Xiaoxia Sheng, Taesung Jung, Jeffrey A. Wesson, Michael D. Ward have a paper "Adhesion at calcium oxalate crystal surfaces and the effect of urinary constituents" in the Proceedings of the Nataional Academy of Sciences. Xiaoxia is now a postdoc at MIT; Taesung Jung was a Brain Korea-21 visiting student, and Jeff Wesson is a collaborator at the Medical College of Wisconsin.

Note: This paper was preceded by one in Langmuir, which also featured the work as a cover. Taesung Jung was the first author on that paper.

Abstract: Kidney stones, aggregates of microcrystals, most commonly contain calcium oxalate monohydrate (COM) as the primary constituent. The aggregation of COM microcrystals and their attachment to epithelial cells are thought to involve adhesion at COM crystal surfaces, mediated by anionic molecules or urinary macromolecules. Identification of the most important functional group-crystal face adhesive combinations is crucial to understanding the stability of COM aggregates and the strength of their attachments to epithelial cell surfaces under flow in the renal tubules of the kidney. Here, we describe direct measurements of adhesion forces, by atomic force microscopy, between various functional groups and select faces of COM crystals immersed in aqueous media. Tip-immobilized carboxylate and amidinium groups displayed the largest adhesion forces, and the adhesive strength of the COM crystal faces decreased in the order (100) > () > (010), demonstrating that adhesion is sensitive to the structure and composition of crystal faces. The influence of citrate and certain urinary proteins on adhesion was examined, and it was curious that osteopontin, a suspected regulator of stone formation, increased the adhesion force between a carboxylate tip and the (100) crystal face. This behavior was unique among the various combinations of additives and COM crystal faces examined here. Collectively, the force measurements demonstrate that adhesion of functional groups and binding of soluble additives, including urinary macromolecules, to COM crystal surfaces are highly specific in nature, suggesting a path toward a better understanding of kidney stone disease and the eventual design of therapeutic agents.

Julia Deneen, graduate student advised by C. Barry Carter, has made it to the MRS Awards for the Spring meeting! The MRS Meeting is April 17 - 21 in San Francisco, CA. The final will be very tough since we can see that the other finalists are at UC Berkeley, Caltech, Northwestern, Harvard, Cambridge, KAIST, Columbia and MIT but making it to the Finals is a great achievement.

Julia Deneen was awarded both an MRS Best Poster Award and a Silver Graduate Student Award for her work entitled "Transmission Electron Microscopy Study of the Mechanical Behavior of Nanoscale Materials" at the MRS 2006 Spring Meeting. The poster award was selected from all the posters presented at the meeting on the basis of the poster's technical content, appearance, graphic excellence, and presentation quality. Julia received a $500 cash prize and her poster was on display throughout the meeting. For the Graduate Student Award, finalists are chosen based on their outstanding performance in the conduct of the project and promise for future substantial achievement in materials research. The award consists of complimentary conference registration, an award certificate, and another cash prize.

The AIChE Chem-E-Car from the University of Minnesota won "Most Creative Drivetrain", was second place in the poster competition and of course placed first in the Car Competition. This particular car was special because it created from scratch in about 2 months and had never competed in a competition before.

The car was powered by a baking soda and vinegar reaction. The gas produced from the reaction created pressure in a closd vessel, and this power was harnessed by connecting it to a piston, whish was then attatched to the car's axel. The car was required to travel 60 feet and stop. After the first run, it was 4 feet away from the 60 feet mark. Then, a few modifications were made to the amounts of reactants added to the vessel, and after the second run the car was zero inches away from the 60 feet mark.

The competition was held at Purdue University in West Lafeyette, Indiana on April 1st. Our team traveled to Purdue for the weekend of March 31st to April 2nd. People involved on the team were Brett Heffelbower, Andrew Larson, Nate Craig, Mike Welch, Jon Seppelt, Ryan Miller, Josh Allen, Kyle Hubbs, Jenna Van Dellen, Matt Rauschke, Greg Hangii, Zack Wilcock, Justin Woo, and Elizabeth Borguson.

Ken Keller will be the Director of the John Hopkins University School of Advanced International Studies, Bologna Center in Italy. Ken will begin his new position in August, 2006.

Joel Bell, a fourth year PhD candidate working with Professor Chris Macosko, will present two papers at the Polymer Processing Society’s international meeting in Yamagata, Japan. The papers are titled "Cocontinuous Polymer Blends: Effect of Block Copolymer on Morphology” and "Imaging of Cocontinuous Polymer Blends."

Cocontinuous morphologies are formed by the interpenetration of two immiscible polymers. Due to their enhanced interfacial area and unique combination of properties, they are used commercially to enhance conductivity, mechanical, absorption, and processing performance of polymers. Yet, cocontinuous blends haven’t been studied to a great degree and offer a fertile area for research. The right combination of mixing flows, component properties, and concentration needed to generate fine interconnected morphology are still to be discovered. A fundamental problem is that cocontinuous blends are inherently unstable as interfacial tension fights to coarsen the morphology. It has been shown that adding a small amount (1% by weight) optimal diblock copolymer (bcp) decreased the initial pore size and nearly stopped coarsening during annealing in PS/PE cocontinuous blends. It appears that the bcp acts to lower the interfacial tension and hinders coarsening. These results along with the effect bcp has on the range of cocontinuity will be discussed at the upcoming PPS conference.

Two dimensional scanning electron microscopy (SEM) has been used to characterize the polymer blends, but in collaboration with Professor Jung Ho Je’s group at Pohang University (POSTECH), South Korea, Bell and coworkers have also developed a novel synchrotron x-ray microtomography method to visualize cocontinuous morphologies in 3D (similar to a “CAT-scan” used for biological imaging). This new tool gives the ability to characterize cocontinuous morphologies in 3D without extracting or staining one of the phases. The technique was used to measure the surface area and changes in pore size during annealing of 50/50 PS/PE blends. Results will also be discussed at the upcoming PPS conference.

Lanny Schmidt was the Julian C. Smith Lecturer at Cornell University School of Chemical and Biomelecular Engineering on April 10 and 11th. Lanny discussed topics on renewable energy.

Chris Leighton had a recent paper in Physical Review Letters: "Exchange Bias as a Probe of the Incommensurate Spin-Density Wave in Epitaxial Fe/Cr(001) with J.S. Parker, L. Wang, K. A. Steiner, P.A. Crowell (Phys. Rev. Lett. 97 227206 (2006)).

Magnetism in metallic films and interfaces has been intensively studied since the discovery of Giant MagnetoResistance (GMR) in the late 1980’s. This effect enabled fabrication of high sensitivity magnetic field sensors for the read heads in magnetic hard disks, revolutionizing magnetic recording. GMR occurs in structures where an ultra-thin “non-magnetic” film is sandwiched between two magnets, Fe / Cr / Fe being a popular example. Although often ignored, the weak magnetism of the Cr film is fascinating in its own right. As in all magnets, this magnetism originates from the arrangement of the spin magnetic moments of the electrons. Cr has one of the most extraordinary spin arrangements that can be found in the entire periodic table. The spins form a structure that is referred to as an antiferromagnetic Incommensurate Spin Density Wave. As shown in the figure, this involves a periodic modulation of the Cr spin, with a wavelength that does not match (i.e. is incommensurate with) the atomic periodicity. Postdoc Jeff Parker, working with graduate student Lan Wang, undergraduate Kim Steiner, and Professors Leighton and Crowell have used a well-known effect in thin film magnetism to directly probe this spin structure even in very thin films where other techniques cannot be applied. The work is based on the concept of interfacial exchange coupling between neighboring layers, using an effect called exchange bias. Exchange bias is an easily measurable perturbation of the properties of a ferromagnetic film due to proximity to an antiferromagnet like Cr. Its great sensitivity to the interface spins in the antiferromagnet means that in Fe/Cr thin film layers one can use the exchange bias in the Fe to probe the spin arrangement in the Cr. In particular, the wavelength of the Cr spin density wave varies with temperature, leading to an oscillation in the Cr surface spin magnitude, and therefore an oscillation in the strength of the coupling to the Fe, with temperature. By measuring these oscillations they were able to determine, in a unique way, important and detailed information on the spin density wave, such as the extent of the wavelength change with temperature, and the critical temperatures at which the nature of the spin density wave changes. The experiment required not only the fabrication of high crystalline perfection epitaxial Fe/Cr films (with very smooth interfaces) but also measurement of the exchange coupling strength to very high accuracy due to the small magnitude of the oscillations.

Kevin Dorfman was awarded a National Science Foundation CAREER award for research on the "Dynamics of DNA during Electrophoresis in Artificial Sieving Matrices".  NSF bestows this award to support the early career-development activities of outstanding young faculty.  Professor Dorfman and his research group are going to use microfabrication to make very precise arrays of pillars for DNA separations.

These "artificial gels" promise to be much better than conventional gel electrophoresis of long DNA, reducing the separation time from hours to minutes and increasing the reproducibility. The problem is that, although there is now pretty good data for the interactions of long DNA and a single isolated obstacle, they do not have a good model for the dynamics of DNA as it moves through an array of many obstacles. They are going to observe these dynamics at the single-molecule level and then use coarse-graining techniques to develop models for the separation process. If successful, the project would yield design equations for the separation.

Research from Renata Wentzcovitch and her group was highlighted in Eos. The article "Spin transition in Magnesiowüstite in Earth’s lower mantle" by T. Tsuchiya, R.M. Wentzcovitch, S. de Gironcoli appeared in Physical Review Letters in 2006.

Electronic spin is a quantum property of every electron, associated with its intrinsic angular momentum. The electronic structure of iron in minerals is generally such that valence electrons will more abundantly occupy different spatial orbitals and maintain the same spin than occupy the same spatial orbital and assume opposite spin, called ‘spin-paired.’ To the astonishment of mineral physicists, pressure-induced electronic spin-pairing that were predicted in iron nearly 50 years ago recently have been detected in ultrahigh-pressure experiments.

The Berkeley Lecturer is an outstanding academic or industrial researcher who presents two lectures over a three day period of time.

Martin Kenward, a postdoc with Kevin Dorfman, won a supercomputing research scholarship from the MSI for the coming fiscal year (July-June). The title of the project is: "Biophysical mechanisms underlying DNAzyme catalysis." DNAzymes are short sequences of single-stranded DNA that act as catalysts when folded in the presence of a cofactor. The most promising DNAzyme, which catalyzes chain scission of mRNA at the start codon, has spawned an active area of clinical research. To date, all DNAzymes have been discovered in the laboratory by directed evolution. Current directed evolution techniques limit DNAzymes to approximately 20 bases, and changing a single base can reduce the catalytic rate by several orders of magnitude. Thus, relating a particular DNAzyme’s sequence to its structure (and fluctuations around that structure) is crucial to understanding their biochemistry, and will aid in the first-principles discovery of new, more powerful enzymes for biotechnology and clinical applications. The specific aim of this project is to correlate insights gained from statistical physics with available biochemical rate data in order to determine the structural features that give rise to stable, highly active DNAzymes.

Efie Kokkoli received a 2007 Camille Dreyfus Teacher-Scholar Award.  The Camille Dreyfus Teacher-Scholar award is based on research accomplishments and potential as well as teaching quality.  Efie is being honored for her research on biomimetic approaches for the design of materials and therapeutics.

Her group focuses on synthesizing and characterizing bioactive peptide-amphiphiles for the design of receptor targeted therapeutics. They attempt to compare and link measurements that address widely different length scales and dynamics, ranging from the single-molecule level all the way to the cell. Different peptide-amphiphiles designed in Efie's lab are further evaluated in their ability to provide targeting functionality to drug delivery systems. Biomimetic peptide-amphiphiles also hold promise for the creation of functional nanostructures and a future goal is to use them for templated materials synthesis.

Prof. Yiannis Kaznessis

The National Science Foundation recently awarded CEMS faculty member Yiannis Kaznessis the NSF CAREER Award, one of its most prestigious awards for new faculty members.  The CAREER program recognizes and supports the early career-development activities of those teacher-scholars who are most likely to become the academic leaders of the 21st century.  Yiannis will receive $400,000 in research funds over the next 5 years.  The topic for Yiannis' proposal was "Mathematics for Biological Engineering".

The current rapid expansion of biological knowledge offers a great opportunity to rationally engineer biological systems that respond to external signals. Indeed, the ambitious idea of engineering biological cells that function as miniature factories has given rise to a new, exciting field of research, synthetic biology.

The inherent complexity of living organisms warrants a quantitative perspective for rationalizing the construction of synthetic biosystems. Professor Kaznessis and his group focus on the development of statistical mechanical theories and accurate mathematical models of biomolecular events that provide insight into the dynamic behavior of biological systems. They also work on designing and experimenting with synthetic biological systems, such as protein devices, inducible gene networks and bio-logical AND gates, with applications in biofuels, biosensors and gene therapies.

Efie Kokkoli

Efie Kokkoli has been awarded a National Science Foundation CAREER award for her work on "Design and Characterization of Aptamer-Amphiphiles for Selective Binding". The CAREER is the National Science Foundation's most prestigious award in support of junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research.

Efie proposes the design and characterization of a novel tool, "aptamer-amphiphiles", based on the expectation that by changing their structural segments one can control their morphology, surface chemistry, and function. A comprehensive characterization of secondary structure, amphiphilic and self-assembly properties, and the link between these properties and the engineering of targeted delivery vehicles is proposed by Efie for the first time. By choosing aptamers that bind to fractalkine as the model system, Efie�s work outlines a logical approach that can be applied to the future design of aptamer-amphiphiles that can functionalize nanoparticles and increase the particle�s specificity and affinity for fractalkine, thus having great therapeutic potential and significantly benefiting society.

The University of Minnesota Department of Chemical Engineering and Materials Science has entered into a partnership with the Petroleum Institute, located in Abu Dhabi, United Arab Emirates, to establish the Abu Dhabi-Minnesota Institute for Research Excellence (ADMIRE). This $6.1 million grant over the next three years will promote joint research projects between the two institutions and foster the continued development of academic programs of the Petroleum Institute, specifically their programs in chemical engineering and materials science and engineering.

A primary goal of the partnership is to establish thriving research projects with an emphasis on energy-related topics. Inter-institutional research groups have been established in the areas of hydrocarbon processing, modeling and simulation, polymer processing, and materials science. Recognizing that petroleum resources will play a vital role in the world's energy portfolio over the next decades, ADMIRE will be at the forefront of making the best use of these limited and increasingly precious resources, while also pursuing innovative projects in the search for energy alternatives of the future.

Through these research projects, faculty and student exchange programs will be established, so that both institutions may benefit from in-residence visits of graduate students, post-doctoral associates, and faculty. About 15 to 20 faculty and a comparable number of graduate students and post-docs from each institution will be involved in the research.

Another significant goal of the partnership is to broaden the interaction between the two programs in undergraduate and graduate education, curriculum development, faculty development, and accreditation activities.

The Petroleum Institute was created in 2001 with the goal of establishing itself as a world-class institution in engineering education and research in areas of significance to the oil and gas and the broader energy industries. Other university partners include the University of Maryland, Colorado School of Mines, Johannes Kepler Universitat Linz in Austria, and Montanuniversitat Loeben in Austria. The Petroleum Institute�s sponsors and affiliates include Abu Dhabi National Oil Company (ADNOC) and four major international oil companies, including Shell and BP. The campus has modern instructional laboratories and classroom facilities and is now in the planning phase of three major research centers on its campus in Sas Al Nakhl, Abu Dhabi.

Prof. Jeffrey Derby will serve as the Director of ADMIRE. Connie Galt will serve as Assistant to the Director, and Prof. Ed Cussler will serve as Chair of the Academic Advisory Board. The points of contact in Abu Dhabi are Prof. Saleh Al Hashimi of the Chemical Engineering Program and Dr. Michael Ohadi, Provost and Acting President, of the Petroleum Institute.

The Office of Emerging Frontiers in Research and Innovation (EFRI) of NSF announced the award of 20 grants in FY 2009, including eight on the topic of Hydrocarbons from Biomass (HyBi). One of the 8 HyBi awards was given to a team of 3 CEMS faculty (Bhan, Schmidt and Tsapatsis) and collaborators from Princeton (Floudas) and the University of Delaware (Vlachos).

The NSF announcement (http://www.nsf.gov/eng/efri/fy09awards_HyBi.jsp) states: "Cooking up hydrocarbons in a unique “pot” The project “Conversion of Biomass to Fuels using Molecular Sieve Catalysts and Millisecond Contact Time Reactors” (0937706) will be led by Michael Tsapatsis of the University of Minnesota. He will collaborate with Aditya Bhan and Lanny Schmidt of the University of Minnesota, Christodoulos Floudas of Princeton University, and Dionisios Vlachos of the University of Delaware. The team’s daring research objective is to develop a fast, continuous, and scalable process for the conversion of lignocellulosic biomass to fuels in only one “pot” — a stratified reactor. They will engineer both the biomass vaporization reaction and the catalytic reactions for removal of oxygen and for building larger, desired hydrocarbons to take place in the same reactor. The researchers believe that their recent advances in controlling thin-film catalysts and modeling reactions and reactor designs will enable them to produce hydrocarbons in this economically attractive way."

The University of Minnesota announced that the Board of Regents approved naming the Electrical Engineering/Computer Science Building in honor of former University president and chemical engineering and materials science professor Kenneth H. Keller. The building was completed during Keller's presidency and is located next to his departmental home of Amundson Hall.

The building will officially be called Kenneth H. Keller Hall, but in more common usage will be referred to as Keller Hall. The naming will be effective July 1, 2010, and the formal dedication ceremony will take place in the fall. The Electrical Engineering/Computer Science Building, located at 200 Union St. S.E., is one of the University's largest academic buildings at more than 336,000 square feet, and is home to the Department of Electrical and Computer Engineering, the Department of Computer Science and Engineering and the Nanofabrication Center. Kenneth H. Keller joined the University of Minnesota chemical engineering faculty in 1964. He subsequently became chair of the Faculty Consultative Committee, acting dean of the Graduate School, and vice president for academic affairs. In 1984, Keller was chosen to be acting president, and in 1985 was named University of Minnesota president, serving the University in that role until 1988. After two years at Princeton University and seven years as a senior fellow at the Council on Foreign Relations in New York, Keller returned to the University of Minnesota in 1996 as the Charles M. Denny, Jr. Professor of Science, Technology, and Public Policy in the Hubert H. Humphrey Institute of Public Affairs. Keller was designated President Emeritus by the Board of Regents in 2006 and is currently director of the Bologna Center of the Johns Hopkins School of Advanced International Studies, a multidisciplinary graduate program in international affairs enrolling students from 35 to 40 countries each year.

Nature always seems to limit our ability to convert energy to useful forms like electric energy. One example is in solar cells where energetic electrons created by absorption of light always lose some of their energy as heat instead of generating electric current. This limits the theoretical efficiencies of traditional solar cells to ~31%. In this week's Science, an article by CEMS graduate student, Will Tisdale, describes how these energetic, "hot," electrons can be captured before they lose their energy. Coadvised by Professors Aydil and Norris in CEMS and Professor Zhu in the Chemistry department (now at U.T. Austin), Will showed that hot electrons created in quantum dots can be transferred to another semiconductor in less than 50 femtoseconds. This is the necessary first step in surpassing the 31% solar cell efficiency on the way towards 66% efficient solar cells, nature's next limit.

We are deeply saddened to learn that Neal Amundson passed away on February 16, 2011.  He joined the Department of Chemical Engineering at the University of Minnesota in 1947, and two years later became the department head.  His innovations in both research and administering the department made him a legend in Minnesota.  The building that houses the current Chemical Engineering and Materials Science department was renamed Amundson Hall in 1979.  Amundson was lovingly referred to as "The Chief".

The University of Houston Department of Chemical and Biomolecular Engineering will host a memorial tribute for Neal R. Amundson on March 14 from 9 a.m. to 12:30 p.m.  To view a live stream of this memorial, look for the link on their departmental home page

Program for University of Houston Memorial to Neal Amundson

When Amundson arrived at Minnesota, Chemical Engineering was essentially taught as an industrial discipline.  He introduced the notion of mathematics to describe and solve reactor and other complicated systems, and continued this trend by becoming one of the first to use early computers to solve complex differential equations.  In doing so he brought science to what was then the "art" of distillation and other solid-fluid interactions.  One of his main research contributions was a 12 part series of papers on the stability and control of chemical reactors in Chemical Engineering Science.

Amundson returned from Cambridge University in 1955 with a vision for making his department the most dynamic in the country.  He wanted faculty with diverse backgrounds, but all well-versed in mathematics.  He proceeded to hire faculty from areas such as chemistry, biology, mathematics, and materials.  His first inspiration was bringing Rutherford "Gus" Aris from England to Minnesota, and this duo went on to establish the mathematical foundation to modern chemical engineering.  Henry Tsuchiya, Bill Ranz, Arnie Fredrickson, John Dahler, Skip Scriven, Ted Davis, and Ken Keller joined the department between 1959 and 1964, and were followed the next year by Lanny Schmidt and Bob Carr.  When chemical engineering and materials science programs merged, Amundson hired polymer chemist Chris Macosko.  With Amundson's leadership, these and others made the Chemical Engineering and Materials Science department the best in the country.

The Chief stepped down as had of the department in 1974, and joined the Department of Chemical Engineering at the University of Houston in 1977, and had a very prominent effect there.  He served as Provost of the University of Houston, and retired as the Cullen Professor of Chemical & Biomolecular Engineering and Mathematics.

Two of his former graduate students in CEMS, Arvind Varma and Dan Luss, have collaborated to write a very nice obituary for The Chief:

The paper "Spin-State Crossover and Hyperfine Interactions of Ferric Iron in MgSiO3 Perovskite", authored by Han Hsu, Peter Blaha, Matteo Cococcioni and Renata Wentzcovitch was featured on the cover of the March 18th issue of Physical Review Letters. Their work is also the subject of a feature in Physics Today.

The total electron spin of a transition metal ion in a solid can vary with pressure, stress, temperature, etc. In addition to its technological potential, this phenomenon, spin-state crossover, also plays a crucial role in geophysics. As the pressure and temperature increase with depth in the Earth, the total electron spin of iron incorporated in minerals can change accordingly. This leads to changes in elastic and thermodynamic properties of the host phases.

Since 2003 it has been known that the major phases of the lower mantle undergo such a crossover. While the spin-state change of iron in periclase (MgO), constituting ~20 vol% of the lower mantle (660-2890 km depth), is now well understood, iron spin states in magnesium silicate (MgSiO3) perovskite, the major mineral phase (~75 vol%) in the same region, have been highly controversial. Such controversy was recently clarified by Hsu et al. (1) via a series of calculations showing that while ferrous iron in MgSiO3 retains its electronic spin throughout the lower-mantle pressure range, ferric iron substituting silicon in the octahedral site does undergo a spin-state crossover and leads to elastic anomalies in MgSiO3. This new finding, combined with previous studies of iron in MgO, provide a more complete picture of how iron spin states affect mantle properties.

The geophysical consequences of this phenomenon are yet to be clarified, but one can anticipate they are profound. At least two major effects, which will trickle down to others, are expected: i) spin crossovers invigorate deep mantle convection increasing the rate of heat extraction from the core and ii) alter the interpretation of observed seismic velocities in the lower mantle in terms of temperature and possibly mineral composition.

These studies illustrate the power of applications of state-of-the-art first principles techniques from computational condensed matter physics to minerals to investigate the interior state and evolution of Earth and other planets.

Alternative carbon sources such as biomass and natural gas will be critical in supplying the planet with energy carriers and other petroleum substitutes in the future. The advantage of using C1 intermediates such as methanol for this conversion is that it does not depend on the source of carbon and it offers a high degree of flexibility in the choice of products. The underlying challenge in this chemistry is to grow carbon chains selectively from C1 precursors to make desired gasoline range hydrocarbons. The Bhan group proposes to develop detailed mechanistic understanding of methanol conversion on zeolitic acids and to exploit the co-catalytic organic "hydrocarbon pool" in MTH systems to tune selectivity for carbon-chain growth reactions. If successful, this research will provide new catalytic routes for converting any carbon source to specific fuel or chemical products

Maria Torija, Manish Sharma, and Josh Schmitt from Chris Leighton's group, working in collaboration with Oak Ridge National Lab, and the National Institute of Standards and Technology have recently cast new light on a central problem in oxide electronics.

Complex oxides are widely recognized as holding enormous potential for many types of electronic devices, such as ultra-fast computer chips, high performance memory, and clean-burning fuel cells. Interfaces between oxides are critical to the performance of these devices however, and the electronic and magnetic properties of the oxides tend to degrade dramatically at interfaces, posing a serious problem. Work published online on April 21st in Advanced Materials reported a breakthrough in the understanding of the origins of this effect. Using a specific cobalt oxide as an example, the group was able to demonstrate that the deteriorated magnetic and electronic properties arise due to a surprising tendency of the materials to break up into nanoscopic magnetic clusters. Atomic resolution microscopy shows this to be due to chemical effects near the interface, primarily related to an unusual interplay between strain and oxygen vacancy formation. Oxygen vacancies form a superstructure in these materials, which was also found to have a profound effect on the Co spin state, as reported in Nano Letters. The work demonstrates that careful engineering of the interface atomic structure could minimize, or even eliminate, this roadblock to development of oxide-based technologies.

A CEMS team described the synthesis of suspensions containing zeolite nanosheets (precisely structured porous layers, few atoms thick and thousand atoms wide). Due to the molecular sized pores crossing the film thickness, the nanosheets can act as selective flakes at the molecular level. High performance membranes were synthesized by simply packing these selective flakes. The paper was published on the October 7 issue of Science (K Varoon et al, Science, 2011, 334, 72 (DOI: 10.1126/science.1208891)). A commentary can be found here .

In an invited Perspective (Science, 334, p.767 (2011)), Michael Tsapatsis discusses an emerging new methodology to fabricate ultrathin (few nanometer thick) molecular sieve membranes. This technology appears now feasible due to several notable developments demonstrated by his research team and collaborators: control of preferential orientation (Science, 300, p. 456 (2003)) , elimination of grain boundary defects (Science, 325, p. 590 (2009)) and synthesis of nanosheet seed crystals (Science, 333, p. 72 (2011)). Commercialization of this technology could lead to significant energy savings in the chemical process industry.

Nanometer-scale semiconductors that contain a few intentionally added impurity atoms can provide new opportunities for controlling electronic properties. However, since the physics of these materials depends strongly on the exact arrangement of the impurities, or dopants, inside the structure, and many impurities of interest cannot be observed with currently available imaging techniques, new methods are needed to determine their location.

Mkhoyan group in collaboration with David Norris's group from ETH Zurich combined electron energy loss spectroscopy with annular dark-field scanning transmission electron microscopy (ADF-STEM) to image individual Mn impurities inside ZnSe nanocrystals. Thus, a general path is demonstrated for atomic-scale imaging and identification of individual dopants in a variety of semiconductor nano structures. The paper was published in Nano Letters ( A.A. Gunawan et al., Nano Lett. 11, 5553 (2011) ) and highlighted in February 2012 issue of Nature Chemistry.

Professor Cococcioni has recently received a National Science Foundation's CAREER award. This award is conferred to junior faculty members to recognize and support outstanding research activities and their integration with excellent educational programs. Matteo's project, entitled "Efficient DFT-based computational approach for correlated systems", proposes to develop, validate and disseminate a flexible and versatile Density Functional Theory - based computational scheme to perform ab initio calculations on correlated and non correlated systems at a higher level of accuracy, yet at approximately the same computational cost of current DFT functionals.

Strongly correlated systems (e.g., many transition metal and rare earths compounds) are involved in applications of unquestionable scientific and technological relevance, including homogeneous and heterogeneous catalysis, solar cells, sensors, actuators, energy conversion and storage devices, spintronics, superconductivity, etc. Available ab initio computational approaches are either not accurate or not efficient enough to treat correlated systems of realistic complexity. The research work Matteo proposes consists in developing corrective terms to the DFT total energy that, inspired by the Hubbard model, will be designed to act on a selected subgroup of the electrons of a system (typically, strongly localized ones) and to reintroduce specific aspects of the many-body character of the electronic wave function, normally lost in common approximate functionals. If successful, this research will define a new paradigm to perform ab initio calculations, whose unique combination of accuracy and numerical efficiency will disclose unprecedented possibilities to effectively use computational modeling to control the properties of materials in this class through design, and to efficiently screen and optimize optimal candidates for target applications.
