Knowledge of solution thermodynamics is fundamental for solution control and solvent selection processes. Herein, experimentally determined thermodynamic quantities for solutions of wood pulp (hardwood dissolving pulp, cellulose) in [-TBDH][AcO] are presented. activities ( ) and associated ( ) activity coefficients ( ), are determined to quantify inherent solution . Access to the Gibbs energy of mixing, , in combination with associated partial molar thermodynamic quantities, reveal strong enthalpically favourable (exothermic) interactions due to solvent-j and solute-i contact-encounters. Onset of an entropy driven phase instability appears at increased temperatures as excess entropic contributions dominate solvation character of the solutions formed.

The significance of iron sulphide (FeS) formation extends to "origin of life" theories, industrial applications, and unwanted scale formation. However, the initial stages of FeS nucleation, particularly the impact of solution composition, remain unclear. Often, the iron and sulphide components' stoichiometry in solution differs from that in formed particles.

Potassium is a harmful impurity in the rhenium sinter, which adversely affects its mechanical properties by significantly reducing the density of sintered rhenium. Cationic resin is a promising material for potassium removal. In this study, the strong acid cationic exchange resin C160H was pretreated with an HNO solution to enhance its performance in potassium removal.

Efficiently obtaining atomic-scale thermodynamic parameters characterizing crystallization from solution is key to developing the modeling strategies needed in the quest for digital design strategies for industrial crystallization processes. Based on the thermodynamics of crystal nucleation in confined solutions, we develop a simulation framework to efficiently estimate the solubility and surface tension of organic crystals in solution from a few unbiased molecular dynamics simulations at a reference temperature. We then show that such a result can be extended with minimal computational overhead to capture the solubility curve.

In the process of zinc hydrometallurgy, the content of fluorine in zinc sulfate solution directly affects the stripping of the zinc plate, which easily leads to the deterioration of working conditions. It not only has a serious impact on the entire zinc hydrometallurgical system but also causes huge economic losses. Especially in the process of zinc secondary resource utilization, the concentration of fluoride ions in the electrolyte exceeds the control standard of smelting enterprises, which has become a long-term technical challenge in the smelting industry.
