Reactions of calcite in water in the presence of stearic acid [PDF]

open access: yesMining and Metallurgy Engineering Bor, 2015
In the suspension of water and calcite, with pH 10.14, on the border of calcite / water was formed a double electric layer. Its structure, or hydrophilic properties of minerals, depended on the concentration of potential determination ions, Ca2+ i 2 CO3 ,

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 ...

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

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.

A General Correlation between the Temperature-Dependent Solubility and Solute and Solvent Molar Masses in Binary n-Alkane Mixtures [PDF]

open access: yes, 2018
An increasingly popular solution in the oil-industry is long-distance sub-sea transportation of unprocessed well-streams. This will commonly expose the oil to temperatures significantly below the reservoir temperature, and possibly below the wax ...

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 ...
