Skin absorption of mixed halide anions from concentrated aqueous solutions

Multicomponent Concentrated Aqueous Electrolyte Solutions

Component dynamics in polyvinylpyrrolidone concentrated aqueous solutions.

(2)H-nuclear magnetic resonance (NMR) and neutron scattering (NS) on isotopically labelled samples have been combined to investigate the structure and dynamics of polyvinylpyrrolidone (PVP) aqueous solutions (4 water molecules/monomeric unit). Neutron diffraction evidences the nanosegregation of polymer main-chains and water molecules leading to the presence of water clusters. NMR reveals the s...

Absorption of copper (Cu2+) and nickel (Ni2+) from aqueous solutions by volcanic ash soil

Introduction: Natural volcanic ash soil is one of minerals whose major contents are metal oxides. In this study absorption of copper (Cu2+) and nickel (Ni2+) on natural volcanic ash soil has been investigated at 27±1c as a function of PH, metal concentration, contact time and the amount of sorbet, using batch experiments. Methods: The necessary samples of natural volcanic ashes were collected...

Accurate description of calcium solvation in concentrated aqueous solutions.

Calcium is one of the biologically most important ions; however, its accurate description by classical molecular dynamics simulations is complicated by strong electrostatic and polarization interactions with surroundings due to its divalent nature. Here, we explore the recently suggested approach for effectively accounting for polarization effects via ionic charge rescaling and develop a new an...

Rotational dynamics of thiocyanate ions in highly concentrated aqueous solutions.

The thiocyanate (SCN(-)) anion is known as one of the best denaturants, which is also capable of breaking the hydrogen-bond network of water and destabilizing native structures of proteins. Despite prolonged efforts to understand the underlying mechanism of such Hofmeister effects, detailed dynamics of the ions in a highly concentrated solution have not been fully elucidated yet. Here, we used ...
