The compressibility factors and second virial coefficients for helium-nitrogen mixtures at low temperature and high pressure
The Burnett method was used to determine the volumetric behavior of helium, nitrogen, and six evenly spaced helium-nitrogen mixtures at low temperature and high pressure. Compressibility isotherms were determined for both ...
Effects of irradiation on the catalytic activity of metal oxides
This work further develops a technique for changing the electronic and defect structure of magnesium oxide and silica gel catalysts. Relatively small doses of ultraviolet and neutron irradiation have been found to enhance ...
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 ...
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 ...
The constitution of silica gel
Abstract Not Available.
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 ...
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 ...
