Engineered surfactants for water treatment

High internal phase emulsion polymer foams are a unique type of adsorbent that can be easily controlled and tailored to improve water quality in many different environments. While a lot of work has gone into using different types of polymers for the foam itself, little work has focused on the surfactant that is required to stabilize the initial emulsion. Not only could an improved surfactant enhance the water treatment properties of the material and make it more suitable to different flow environments, but the surfactants can also pose an environmental challenge of their if not treated properly. This work will focus on making new surfactants that have improved covalent interactions with the polymer adsorbent to reduce the environmental a...

computational catalysis

The control of chemical transformation via catalysis is both an exceptional intellectual challenge and critically important to the Nation. Catalysis is central to energy production and utilization, to chemical manufacturing, to the minimization of environmental impact, and it has been arguably the single most important agent for sustainable development in the developing world. The revolutions in nanotechnology and high performance computing provide unprecedented new opportunities to elucidate the fundamental principles governing the control of chemical transformation by catalysts. Indeed, the coupling of theory, modeling and simulation with experiment will provide the most profound insights into catalyst behavior and thus enable the design ...

Bioinorganic chemistry of chromium/new drugs for diabetes

Elucidation of the structure, function, and mode of action of metallobiomolecules.The elucidation of the structure, function, and mode of action of metallobiomolecules via: 1) spectroscopic, magnetic, kinetic and biochemical studies of the natural systems and 2) the synthesis and characterization of biomimetic inorganic complexes. Our research applies biochemical and synthetic and physical inorganic methods to characterize the function and properties of metallobiomolecules (naturally occurring molecules such as proteins, nucleic acids, sugars, etc. that contain tightly bound metal ions). The presence of the metal ions gives these species unique magnetic and spectroscopic properties (such as color) that provide avenues (not available to t...

Computational peptide chemistry

Advanced computational electronic structure methods will be used to calculate the geometries, vibrational frequencies, energetics, and excited state properties of important compounds of biological interest. Both correlated molecular orbital theory and density functional theory will be used. The focus of the work is on charging of peptides for explaining mass spectrometry results for both cationic and anionic peptides. The cationic work will focus on transition metal ion charging. Both types of studies are relevant to the study of the Human proteome....

Computational heavy element chemsitry

We are interested in developing a fundamental and predictive understanding of actinide chemistry in aqueous solution under conditions relevant to nuclear-waste storage and reprocessing of spent fuel to address aggregate and colloid formation. Intractable, small aggregates in nuclear-waste streams can impair clean-up, forcing a low-level waste stream to be treated as high-level waste, thereby increasing treatment costs. Metal oligomers, aggregates, clusters, nanophases and colloids are ubiquitous in aqueous chemistry. Thought to form via the condensation reactions of hydrolyzed metal ions, intrinsic dissolved aggregates or colloids are generally described as poly-dispersed hydroxides or hydrous oxides with varying stoichiometry and no well-d...
