Phase transformations in aqueous low molar mass poly(vinyl methyl ether) solutions: Theoretical prediction and experimental validation of the peculiar solvent melting line, bimodal LCST, and (adjacent) UCST miscibility gaps
Article Abstract:
Several experimental and theoretical predictions based on the modulated temperature differential scattering calorimetry are used to study the phase transformations in aqueous low molar mass poly(vinyl methyl ether) solutions. The process used is extremely sensitive towards the measuring board and confirms all the observed properties like the solvent melting line, bimodal lower critical solution temperature (LCST), as well as the upper critical solution temperature (UCST) miscibility gaps.

Effects of poly(vinylpyrrolidone) on proton-transfer reaction in propylamine aqueous solution by ultrasonic relaxation
Article Abstract:
The ultrasonic absorption coefficients in the frequency range from 0.8 to 220 MHz were measured in aqueous solution of propylamine in the presence of poly(vinylpyrrolidone) (PVP) with several polymerization degrees at 25 degreeC. A single Debye-type relaxational absorption was observed when propylamine coexists in solution, and the cause of it was attributed to a perturbation of chemical equlibrium associated with a proton-transfer reaction.

Combination of the replica-exchange Monte Carlo method and the reference interaction site model theory for simulating a peptide molecule in aqueous solution
Article Abstract:
An attempt is made to combine the replica-exchange Monte Carlo method and the reference interaction site model (RISM) theory for simulating a peptide molecule in aqueous solution. It is argued that employing the combined approach reduces the number of replicas required for peptide molecule immersed in water.
