Solar Water Oxidation by Composite Cobalt-Based Catalyst/Oxide Semiconductor Photoanodes
Photoelectrochemical (PEC) water splitting is an attractive approach to capturing and storing the earth's abundant solar energy influx. The challenging four-electron water-oxidation half-cell reaction has hindered this technology, giving rise to slow water oxidation kinetics at the photoanode surfaces relative to competitive ...
Coarsening dynamics of domains in lipid membranes
We investigate isothermal diffusion and growth of micron-scale liquid domains within membranes of free-floating giant unilamellar vesicles (GUVs) with diameters between 80µm and 250µm. Domains appear after a rapid temperature quench, when the membrane is cooled through a miscibility phase transition such that coexisting ...
From Geometry Optimization to Time Dependent Molecular Structure Modeling: Method Developments, ab initio Theories and Applications
This dissertation consists of two general parts: I. developments of optimization algorithms (both nuclear and electronic degrees of freedom) for time-independent molecules and II. novel methods, first-principle theories and applications in time dependent molecular structure modeling. In the first part, we discuss in specific ...
Chemical Strategies to Enrich Malarial Proteins from Wheat Lysate
Malaria is a major public health burden and developing the next generation of anti-malarials is vital to control the spread of disease. Protein arrays, which can investigate binding of many proteins to various probes simultaneously, are becoming an important tool in the drug development process. Results from protein arrays ...
Probing Buried Interfaces within Organic Diodes Using Electromodulated Transmittance Spectroscopies
We used two electrically-modulated transmittance spectroscopies on various device structures to gain better understand the physics built into interfaces within organic diode structures. In one line of investigation we noninvasively probed the buried interface between the transparent indium tin oxide (ITO) electrode and the ...
Unraveling Dispersed Kinetic Behavior of Single Photoacid Molecules in Transparent Crystal Hosts
This dissertation represents construction and application of powerful tools for single molecule (SM) photophysical analysis. SM fluorescence intermittency studies are presented for violamine R (VR) and 2',7'-dichlorofluorescein (DCF) isolated in potassium acid phthalate (KAP) crystals. Both dyes were shown to follow a broad ...
