Ionic volumes, compressibilities and electrostriction of electrolyte solutions.
A theory of electrostriction of solvent water near ions is developed. The treatment is based on a calculation of the effective pressure which would, in the absence of the field, cause the she change in volume as does the field. It is shown that when the dissolution process is from the crystalline …

ESTIMATION OF DIFFERENT COAL COMPRESSIBILITIES OF COALBED METHANE RESERVOIRS UNDER REPLICATED IN SITU CONDITION
… An accurate estimation of different coal compressibilities is, therefore, critical in CBM operations in order to model and project gas production rates. Furthermore, a comprehensive knowledge of the dynamic permeability helps in understanding the unique feature of CBM production, an …

Thermodynamic and kinetic studies of purple membrane from halobacterium halobium
… thermal expansivity, isothermal and adiabatic compressibilities, and specific heats at constant pressure and constant volume. In the final experiment, we studied the effects of high pressure on the kinetics of the photocycle. We found that all of the distinct processes in the photocycle are …

Bonding properties of coordinated polyhedra in molecules and crystals
… effective nuclear charges and polyhedral compressibilities of molecules and crystals. Model electron density distributions calculated for a large number of molecules with MOn (n = 1, 2,3,4 or 6) coordination polyhedra show that the MO bonds of a given type vary in a regular way with the …

Application of electrospun fiber membranes in water purification
… membranes are found to be functions of their compressibilities. Hydraulic permeabilities of electrospun PSU membranes experience a decrease of more than 60% in permeability between 5 and 140 kPa, due to the increase in solidity, attributed to flow-induced compression. This behavior is …

Two-Dimensional Finite Element Analysis of Porous Geomaterials at Multikilobar Stress Levels
… shear-induced volume changes. Fluid and solid compressibilities were incorporated into the code, and partially-saturated materials were simulated with a "homogenized" compressible pore fluid. Solutions for several verification problems are given as proof that the program works correctly, and …
