N-HETEROAROMATIC ACID ADLAYER STRUCTURES UNDER HYDROGEN BONDING INFLUENCE:
(2007-02-20)
In this dissertation, I investigate the adsorption and growth of thin films of N-heteroaromatic acids and related molecules on Ag(111) surface. The N-heteroaromatic acids have ring-nitrogen and carboxylic groups. Hence, ...
ELECTROCHEMICAL OXIDATION KINETICS OF HYDROGEN AND HIGHER HYDROCARBON FUELS ON SOLID OXIDE FUEL CELLS.
(2007-11-27)
Solid oxide fuel cells (SOFCs) are promising electrochemical energy converting devices due to their ability to use not only hydrogen but also hydrocarbons as a fuel. Although conventional SOFCs with Ni/YSZ anodes and ...
Barcoded Silica Nanotubes for Bioanalysis
(2007-09-25)
Analysis of the chemical/biological species involved in health care is the most important step for diseases diagnosis and new drug screening. Barcoded nano/microparticles are attracting more and more interest for detection ...
SITE-DIRECTED MUTAGENESIS OF GROEL:DEVELOPING A SYSTEM FOR MONITORING ALLOSTERIC MOVEMENTS BY FLUORESCENCE RESONANCE ENERGY TRANSFER
(2007-01-02)
The Escherichia coli chaperonin protein GroEL can assist protein folding to its native state through the consumption of ATP. Accompanying this process, GroEL undergoes structural change, resulting in an expansion of the ...
One-Dimensional Free Energy Surface Models of Protein Folding: Connecting Theory and Experiments
(2007-04-27)
Experimental techniques have now reached the sub-microsecond timescale necessary to study fast events in protein folding. However, analysis of fast folding experiments still commonly rely on conventional procedures that ...
Quantum mechanical investigation on the vibrational relaxation of HF in collisions with H atoms
(2007-05-10)
We investigate the vibrational relaxation of HF(v=2-5) in collisions with H atoms by means of fully-quantum reactive scattering calculations. Our calculations are based on the global ab initio potential energy surface of ...
Hierarchical Intermolecular Interaction Models of N-Heteroaromatic STM Adlayer Structures
(2007-11-28)
The molecular scale electronic device concept was initiated in 1974 with the semi-quantitative analysis of a hemiquinone molecule. Because of the molecule's electron donor and acceptor properties, and ability to transfer ...
An Investigation of Solid Oxide Fuel Cell Chemistry: A Spectroscopic Approach
(2007-05-31)
Solid oxide fuel cells (SOFCs) represent an alternative power source that utilizes hydrogen and/or hydrocarbon fuels at significantly higher efficiencies than combustion systems; however, molecularly specific fuel oxidation ...
SOURCE DEPENDENT VARIATION IN HYDROXYL RADICAL PRODUCTION BY AIRBORNE PARTICULATE MATTER AND THE IMPACT ON BEAS-2B AND JB6 CELLS
(2007-04-30)
Numerous studies have shown an association between increased levels of particulate matter (PM) and the exacerbation of lung diseases. The exact means by which PM produces these effects remain unclear. Generation of reactive ...
Toward Optimization of Photomodulation of Azobenzene-modified PPV Derivatives
(2007-10-01)
Photophysical characterization of a family of photoswitchable conjugated polymers is presented in this work. Additionally the instrumentation constructed for these studies, a time-correlated single photon counting ...
