Intercalated MoS2 Nanoparticles for Enhanced Dispersion in Smokes and Obscurants
(2003-12-05)
The intercalation of MoS2 with diethyl oxalate (DEO) and Meldrum's Acid (MA) has been achieved via an exfoliation and reflocculation process. Ethyl diazoacetate (EDA) did not intercalate under identical conditions. The ...
ORBITAL-FREE DENSITY FUNCTIONAL THEORY OF ATOMS, MOLECULES, AND SOLIDS
(2005-11-23)
Density functional (DF) theory has proved to be a powerful way to determine the ground state energy of atoms, molecules, and extended systems. An important part of the theory requires one to determine the kinetic energy ...
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 ...
Stretching Biomolecules
(2005-11-23)
Biomolecular self-assembly is the complicated processes characterized by broad and hierarchical structure of energy, length, and time scales.
Various experimental tools have, for decades, been used to understand the ...
Protein folding and amyloid formation in various environments
(2008-11-21)
Understanding and predicting the effect of various environments that differ in terms of pH and the presence of cosolutes and macromolecules on protein properties is a formidable challenge. Yet this knowledge is crucial in ...
Investigations of Solvent Polarity at Liquid/Liquid Interfaces by SHG Spectroscopy Using Molecular Rulers
(2004-04-28)
Homologous series of solvatochromic surfactants have been synthesized to study polarity at liquid/liquid interfaces. Each surfactant series consists of hydrophobic, para-nitroanisole-based chromophores attached to ionic ...
The role of charge in solvation at liquid/liquid interfaces
(2005-05-27)
This dissertation describes the development and characterization of new surfactants, dubbed "molecular rulers," that provide an upper limit to the dipolar width in aqueous/organic systems. Here, dipolar width describes the ...
Barrier Heights and Diffusion Coefficients in Protein Folding
(2007-08-03)
A widely held view with respect to the folding of single-domain proteins is that they are two-state. In other words, it is seemingly sufficient to invoke just two thermodynamic macrostates - folded and unfolded - to explain ...
Characterization of TATA Box Binding Protein Interaction with Minicircle DNA
(2005-10-05)
Protein-induced bending of DNA plays an important role in regulating its transcription, replication, recombination, and packaging into nucleosomes. In particular, many general and gene-specific transcription factors bend ...
MULTIPHOTON ABSORPTION: FABRICATION, FUNCTIONALIZATION AND APPLICATIONS
(2009)
Despite the remarkable progress in micro/nano-scale fabrication that has occurred over the last decades, feature sizes are still restricted by the diffraction limit. The resolution in conventional photolithography is ...
