В работе представлен обобщенный анализ литературных данных по электрохимическим и кинетическим характеристикам мембранных систем при использовании ионообменных материалов. Исследование вольтамперных, омических характеристик электропроводности систем, оснащенных мембранами УФМ-50, разделении водного раствора сульфата калия выявило несколько характерных участков на зависимости i - f (U). Линейный...

grenzen gedacht werden. An der Reinphase des EuO sowie an dem mit 3 % EU2O3 vermischten Monoxid wurde die Aktivierungsenergie im Bereich 300 °C bis 200 °C bestimmt und in Tab. 3 zusammengestellt. Man erkennt hieraus, daß die durch Chemisorption der Donatoren CO" hervorgerufene Verarmung der Randschicht an Ladungsträgern mit einer Zunahme der Aktivierungsenergie verbunden ist. Deshalb muß angeno...

Potassium sulfate crystals orient and overgrow 2-aminobenzenesulfonate, among many other sulfonated aromatic compounds, on particular facets during growth from solution. Energies associated with adsorption were calculated using the program MARVIN in order to assess the mechanisms of the face-specific recognition phenomena. Comparisons between computations for fixed and relaxed surfaces are pres...

T, .ranscorneal potentials have been reported by several laboratories and have been related to an active transfer of sodium ions across the cornea. Both epithelial and endothelial cells have been implicated as sites of a metabolic pump. The active transport of ions across the cornea is involved in the maintenance of hydration, thickness, and transparency." The effect of these ions may be indire...

The article deals with the effect of potassium sulfates on setting behavior cement pastes. It has been established that main elements (Ca, Si, Al) are distributed in composition clinker minerals, while K and S atoms concentrated locally pores formation arcanite. is shown interaction K2SO4 CaSO42H2O followed by syngenite K2Ca(SO4)2H2O causes destructive phenomena

In this study, we demonstrate the effects of surfactants on morphology Nb2C MXene-derived ferroelectric KNbO3 crystals. We synthesized plate-like crystals using MXene and KOH as niobium potassium sources, respectively, sodium dodecyl sulfate surfactant. addition, conducted same hydrothermal process for benzyltriethylammonium chloride a surfactant; found that final product exhibits bulk morpholo...
