Separation of isomeric xylenes by pervaporation through cellulose ester membranes [PDF]

open access: yes, 1982
The interaction between the isomeric xylenes and different cellulose esters was investigated using solubility parameter considerations and through measurements of swelling values.

Correlating Interlayer Spacing and Separation Capability of Graphene Oxide Membranes in Organic Solvents. [PDF]

open access: yes, 2020
Membranes synthesized by stacking two-dimensional graphene oxide (GO) hold great promise for applications in organic solvent nanofiltration. However, the performance of a layer-stacked GO membrane in organic solvent nanofiltration can be significantly ...

Hydrocarbon molar water solubility predicts NMDA vs. GABAA receptor modulation. [PDF]

open access: yes, 2014
BackgroundMany anesthetics modulate 3-transmembrane (such as NMDA) and 4-transmembrane (such as GABAA) receptors. Clinical and experimental anesthetics exhibiting receptor family specificity often have low water solubility. We hypothesized that the molar

Study of equilibrium dissolution of WO3–CaSO4 in HCl–Na2SO4 solution

open access: yes工程科学学报, 2023
There are numerous issues in the mainstream process of alkali decomposition of tungsten ores, such as large water consumption, large amounts of wastewater, and high processing costs, which add the dual pressure of economic and environmental protection on

Solubility of Alkylporphyrins [PDF]

open access: yesMolecules, 2000
The solubility in benzene and ethanol of 2,8,12,18-tetramethyl-3,7,13,17-tetrabuthylporphyrin with various substituents in the5,15-positions of the molecule is investigated. A comparative analysis of the influence of alkyl substituents on porphyrin solubility is carried out.

Calculation of solubility in titanium alloys from first-principles

open access: yes, 2009
We present an approach to calculate the atomic bulk solubility in binary alloys based on the statistical-thermodynamic theory of dilute lattice gas. The model considers all the appropriate ground states of the alloy and results in a simple Arrhenius-type

Solubility Interactions in Compensated, Heavily Doped Germanium [PDF]

open access: yes, 1965
The solubility of the two donors, arsenic and antimony, in Ge at 870°C was enhanced by the acceptor dopant Ga at concentrations ≥ 10^19 cm^–3. The observed enhancement is in agreement with theory of the dopant-carrier ionization equilibrium in the ...

The Role of Configurational Entropy in Amorphous Systems

open access: yesPharmaceutics, 2010
Configurational entropy is an important parameter in amorphous systems. It is involved in the thermodynamic considerations, plays an important role in the molecular mobility calculations through its appearance in the Adam-Gibbs equation and provides ...
