Effect of oils, soap and hardness on the stability of foams
A systematic study of foam stability in the presence of model nonpolar oils and their mixtures with oleic acid was conducted for two commonly used surfactants (anionic and nonionic) under neutral and alkaline conditions ...
EXPLICIT FINITE DIFFERENCE SCHEMES BASED ON THE MODIFIED METHOD OF CHARACTERISTICS AND THEIR APPLICATION TO THE MISCIBLE DISPLACEMENT PROBLEM
A class of convection-diffusion parabolic boundary value problems is considered in this study. When convection dominates over diffusion, the solutions of such problems exhibit an almost hyperbolic behavior. Initial conditions ...
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 ...
Interplay of micro-scale flow and fluid micro/nanostructure: Solutions of DNA and suspensions of single walled carbon nanotubes
The dynamics of dilute solutions of DNA flowing in a scaled clown roll-knife free surface coating flow are investigated on multiple scales. The flow is generated between a rotating roll and a stationary glass knife. Extension ...

Novel approaches for the production of fuels and chemicals in Escherichia coli
Volatility of oil prices along with major concerns about climate change, oil supply security and depleting reserves have sparked renewed interest in the production of biofuels and biochemicals. While the carbohydrate portion ...
Derivation of an infinite-dilution activity coefficient model and application to two-component vapor-liquid equilibria data
Infinite-dilution fugacity coefficients were obtained for the binary system fluorene/phenanthrene at thirteen temperatures by fitting total pressure across the entire mole fraction range by a computer routine. A thermodynamically ...
Incorporation of carbon nanotubes in epoxy polymer composites
The goal of this research was to develop and explore methods for incorporating Single-Walled Carbon Nanotubes (SWNTs) into polymer matrices, to form composites, in which the presence of SWNTs would improve significantly ...
An Investigation of Carbon-based Nanomaterials for Efficient Energy Production and Delivery
Carbon-based nanomaterials have been demonstrated to have different potential applications in the energy industry. However, there are challenges in the realization of these applications. Chirality of single wall carbon ...
