Abstract—The probability of the formation of solid iron borides and boron and iron carbides from Fe–C–B melts is thermodynamically estimated. The Gibbs energy of a chemical reaction is taken as a criterion for the solidification of these phases. The following standard states are used: for iron, pure liquid iron; for carbides and borides, a pure sol...

AbstractPotentiometric titration and spectrophotometry are used to determine the stepwise protonation constants of nicotinate ions at 298.2 K and the ionic strength of the medium of 0.25 (NaClO4) in water–dimethylsulfoxide solutions. It is established that the dependence of the protonation constants of nicotinate ion on the composition of the solve...

AbstractThe Gibbs energy of transfer is determined via the interphase distribution of a substance between two immiscible phases. β-cyclodextrin (βCD) from water is used in a mixture with dimethylsulfoxide (χDMSO = 0.0–0.6 mole fraction) at 298 K. The effect of the solvent’s composition has on the thermodynamic characteristics of βCD solvation is an...

AbstractQuantum chemical modeling is used to study the equilibrium geometric parameters and atomic charges in molecules of ethylenediamine (En) in the free state, methanol (MeOH), acetonitrile (AN), N,N‑dimethylformamide (DMF) and dimethylsulfoxide (DMSO), along with the Gibbs energies and enthalpies of amine solvation in the considered solvents. I...

The current situation with the SARS-CoV-2 pandemic indicates the importance of new approaches in vaccine design. In order to design new attenuated vaccines, to decrease virulence of virus wild types, it is important to understand what allows a virus to hijack its host cell's metabolism, a property of all viruses. RNA and protein sequences obtained ...

The history of volume phase transition of responsive gels from its theoretical prediction to experimental discovery was described and the major role of mixing Gibbs energy function in theoretical models was stressed. For detailed analysis and fine tuning of the volume phase transition, the generalized Flory–Huggins model with concentration and temp...

AbstractThe economic feasibility of applying aluminum as a conductor is explained by the favorable ratio of its cost (which has remained almost constant for many years) to the cost of copper. When using conducting aluminum alloys to fabricate thin wire, winding wire, etc., some difficulties can appear in connection with their insufficient strength ...

AbstractThe formation of silver(I) complexes with 2-mercaptobenzimidazole (MB) in solutions containing different amounts of ethyl alcohol is studied via potentiometric titration. The acid–base properties of 2‑mercaptobenzimidazole are studied under the same conditions. It is shown that the 2-mercaptobenzimidazole molecule is protonated in the pH ra...

The hitherto scarcely investigated retro-carotenoid rhodoxanthin possesses high potential for coloration in the food and beverage industry using technofunctional formulations prepared thereof. Hence, we studied (E/Z)-isomerization pathways of rhodoxanthin, including seven (E/Z)-isomers comprising (Z)-configured double bonds at unusual exocyclic and...

The presence of phenol in water bodies exists due to the discharge of wastewater from industrial, agricultural and domestic activities. Its presence in water is associated with a decrease in the quality of drinking water because its change the taste and odour [1]. The adsorption process is one of the most used treatments to remove the phenol of wat...
