Anaerobic transformation of 2,4,6-trinitrotoluene by Clostridium acetobutylicum
In this work, rapid TNT ($>$150 mg/L) transformation by Clostridium acetobutylicum via a reductive pathway to monoaminonitrotoluenes, diaminonitrotoluenes, and on to undetectable end products was observed. The maximum ...
Associating fluids near a hard planar wall
The properties of fluids near a fluid-solid interface are important in many processes, such as: wettability as related to oil recovery and environmental cleanup, biochemical separation, bio-compatibility of materials, ...
Adsorption studies on clays
The object of the present work has been to study the adsorption of hydrocarbon vapors on various types of clays, and to learn from this adsorption study the relative importance of various factors, both chemical and physical, ...
A study of the naphthenic acids from Aruba petroleum
Abstract Not Available.
Hydrodynamic and molecular dependence of neutrophil-neutrophil adhesion
Homotypic adhesion of neutrophils stimulated with chemoattractant is analogous to capture on vascular endothelium in that both processes depend on L-selectin and $\beta\sb2$-integrin adhesion receptors. Under hydrodynamic ...
Molecular modeling and Monte Carlo simulation of concentrated aqueous alkali halide solutions at 25 C
A study of concentrated aqueous alkali halide solutions is made at the molecular level, through modeling and computer simulation of their structural and thermodynamic properties. It is found that the HNC approximation is ...
Rates of solubilization of triolein and triolein/fatty acid mixtures and dissolution processes of neat surfactants
Videomicroscopy was used to measure rates of solubilization of triolein drops injected into thin, rectangular glass cells containing solutions of nonionic surfactants and their mixtures with alcohols at various temperatures. ...
Van der Waals model of liquid wetting layers
A phenomenological theory of wetting layer systems based on the van der Waals theory of interfaces is developed. For classical critical exponents the local composition profile and the wetting layer thickness are determined ...
Prediction of the thermodynamic properties of associating polyatomic fluids
Thermodynamic properties of associating polyatomic fluids are studied using molecular simulation and theory. The overall goal of this study was to develop a theory to predict the properties of fluid mixtures with intermolecular ...
Interfacial properties of fluid phases in two dimensions and of three-component surfactant systems
In this thesis, we study two fundamental problems in the theory and experiment of interfaces in simple and complex fluids. The first problem concerns the critical behavior of the thickness of interface of simple fluids in ...
