The study of high pressure vapor-liquid equilibria by gas-liquid partition chromatography
A method has been investigated for measuring vapor-liquid equilibrium ratios, or K-values, of a solute distributed between a gas phase and a non-volatile liquid phase. A gas-liquid partition chromatographic technique is ...
Characterization and modeling of the pH-regulated expression vector, pSM-10
A new type of plasmid vector has been developed for Escherichia coli. Foreign gene expression can be altered by external pH changes. pSM-10 is the first generation of these plasmid constructs that utilizes the cadA operon ...
Migration of anchorage-dependent mammalian cells
Cell migration affects many physiologic and pathologic processes in mammalian organisms. Thus, our ability to modulate these processes depends on understanding how cell migration is controlled by soluble factors, cell-substrate ...
Dynamics of plasmid-containing cells in a chemostat under transient conditions
One of the major concerns in the utilization of plasmid-containing organisms in fermentation processes is the stability of the plasmid. In general, it is observed that two parameters, the probability of plasmid loss due ...
The constitution of silica gel
Abstract Not Available.
Large-scale production and purification of single-walled carbon nanotubes
Single Walled Nanotubes were produced in large scale by Laser Vaporization with maximum yields of 50%. Optimization experiments give relative yields of (Nickel Cobalt (1:1 atomic % each)) = (Nickel Tungsten (1:1)) $>$ ...
Viscosity and spin-lattice relaxation time of supercritical carbon dioxide-n-hexadecane mixtures, and molar density and isobaric heat capacity ratios for dense fluids
In part one, correlations between viscosity and proton spin-lattice relaxation time are developed for CO$\sb2$ - n-Hexadecane mixtures in equilibrium with their vapor-phase in the vicinity of critical points. A microscopic ...
Stress as a means to enhance secondary metabolite productivity and to probe metabolic pathways
The objectives of this research were to study metabolic pathways in C. roseus hairy root cultures, and to enhance secondary metabolite productivity using fungal elicitation as the technique. The effects of age of inoculum ...
Modeling and simulation of monolith reactors
Monolith reactors are studied with models and simulations, with particular attention given to the catalytic converter. It is found that previously noted differences between one- and two-dimensional monolith reactor models ...
Thermodynamics and kinetics studies of formation and decomposition of clathrates hydrates of methane, carbon dioxide and their mixtures using a differential heat flux calorimeter
A high pressure heat flux calorimeter in isobaric, temperature-ramping mode has been used to measure the solubility of pure methane, pure carbon dioxide and methane-carbon dioxide mixtures. The solubility measurements ...
