EFFECTIVE DIFFUSIVITIES IN CHAR PARTICLES (DIFFUSION, FAST FOURIER TRANSFORM, PYROLYSIS, COAL, FLUIDIZED BED)
Illinois #6, Illinois #5, Pittsburgh #8 coal and Texas Lignite particles of size range 150-16 mesh were pyrolyzed at a heating rate of 3.8 K/min up to 900(DEGREES)C. A stainless steel annular fluidized bed reactor yielded ...
Characterizing water-in-oil emulsions with application to gas hydrate formation
This thesis implements nuclear magnetic resonance (NMR) techniques to directly measure water-in-oil emulsion properties and gas hydrate formation. This thesis introduces a novel application of the pulsed field gradient ...
Catalytic Oxidation Properties of Palladium-decorated Gold Nanoparticles
Bimetallic palladium gold (PdAu) catalysts have been shown to be superior to monometallic ones in many reactions, but the reasons for the enhancement are not thoroughly understood. In this work, palladium decorated gold ...
Characterization & Application of Immobilized Biomacromolecules using Microcantilever and QCM Sensors
The structure and function of immobilized biomacromolecules are likely to be altered because of the solid surface. The long-term objective of this thesis is to develop surface-based biosensors for the characterization and ...
Complex fluids at interfaces and interfaces of complex fluids
The present thesis deals with two independent projects and is consequently divided into two parts. The first part details a computational study of the fluid structure of ring-shaped molecules and their positional and ...
LIQUID CRYSTAL TO MICROEMULSION TRANSITIONS IN ANIONIC SURFACTANT-OIL-BRINE SYSTEMS
Various anionic surfactant-oil-brine systems were studied to understand the transition between liquid crystal and microemulsion phases produced by changes in composition. This work involved equilibrium phase behavior studies ...
Interaction of platelets in flowing blood with collagen-coated surfaces: Effect of inhibitors of platelet function orvon Willebrand factor binding domains
A parallel-plate flow chamber and epifluorescence video microscopy with digital image processing techniques were used to investigate the mechanisms of mural thrombus formation and to evaluate new potentially useful ...
Viscosity Evaluation of Heavy Oils from NMR Well Logging
Heavy oil is characterized by its high viscosity, which is a major obstacle to both logging and recovery. Due to the loss of T 2 information shorter than the echo spacing ( TE ), estimation of heavy oil properties from NMR ...
Mechanisms of symmetric and asymmetric drainage of foam films
The drainage of horizontal thin liquid films produced from aqueous solutions of ionic surfactants was studied experimentally, using videomicroscopy and interference techniques, for several surfactants in a wide range of ...
