Machine Learning in Chemical Sciences

We are interested in predicting the macroscopic properties of chemical compounds based on their chemical structure and molecular properties using advanced machine learning models. Students are expected to learn data analysis techniques based on support vector machine, decision tree, and neural networks as well as build database on which these analyses will be done. No previous knowledge of machine learning techniques is needed. Matlab knowledge is an advantage....

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 ...

Synthesis and characterization of shape/size-controlled metal oxides nanopowders

The research objective of this project is to advance the fundamental understanding of structural and chemical features (morphology, size, atomic-level structure, etc) of metal oxide nanomaterials in order to develop stable catalysts with high reducibility at low temperatures for the application in automotive catalytic converter. Using low-temperature hydrothermal method, students will prepare a series of high surface-area metal oxides nanopowders with a focus on controlling particle morphology and size in such a way that highly catalytically active crystal faces are exposed on the particle surfaces. X-ray diffraction (XRD) will be used to establish the overall crystal structures of the nanopowders. The overall reducibility and catalytic act...

Fluid mechanics for elementary school students via high-speed flow imaging using smartphones & tablets

The purpose of the study is to explore multiple ways in which STEAM (Science, Technology, Engineering, the Arts, and Mathematics) can fit into 3rd to 5th grade elementary education and investigate student learning from an after-school program centered around fluid mechanics. We will recruit UA pre-service teachers and engineering students, especially females, to lead the proposed STEAM activities and serve as mentors. During our initiative, we will conduct surveys and interviews, and evaluate students’ artistic work and technical understanding, to quantify the impact of our program on students’ learning. Fluid mechanics has been a college-level or above subject, while there are many interesting phenomena around us (e.g. diffusion of t...

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...
