Heterogeneous Catalysis: synthesis, characterization, and kinetics

Undergraduate researchers in the Harris Laboratory participate in research projects related to heterogeneous catalyst synthesis, characterization, and measurement of reaction kinetics. As much as possible, students will have their own independent research projects in addition to responsibilities related to multi-student research thrusts in production of renewable fuels, chemicals, and protection of air and water quality. Students are expected to commit to ten hours per week of research activity that will be guided by Dr. Harris and his graduate students. Students are also expected to commit to working in the lab for a minimum of two semesters. Students will prepare final reports summarizing their efforts, and present in our laboratory gr...

Evaluating Novel Surfactants for High Internal Phase Emulsion Polymer Foams as Water Treatment Technology

The Koh Lab is currently working on developing new surfactants with a variety of different structures to create high internal phase emulsion polymer foams (pHIPE). With this library of surfactants we need to characterizing interfacial tension and then utilize the highest performing surfactant to create adsorbent foams. This project will involve the fundamental characterization of the surfactants, with the additional project of building a suitable enclosure for the instrument, as well as the creation of pHIPE. Final aspects of this project will be the validation of adsorbency of the pHIPE using simple contaminants....

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...
