The anodic behavior of zinc in aqueous salt solutions
… metals such as zinc, cadmium, and magnesium in salt solution is not completely known. Many mechanisms have been proposed by different investigators but evidence is still lacking which would allow one to draw reliable conclusions and to explain the discrepanies which often arise between …

Steric and electrosteric stabilization of colloids in aqueous salt solutions
… stability, especially in the case of aqueous salt solutions. The purpose of this study is to explore two such issues.The first issue concerns the details of the attached polymer's conformation, which is often ignored. In this study, it is shown that only a few long attached "tails" of polymer …

Sessile droplets of salt solutions on inert and metallic surfaces
… behaviour of sessile droplets of aqueous saline solutions on planar inert and metallic surfaces and characterise the corrosion phenomenon for iron surfaces. First we study the evaporation behaviour of sessile salty droplets on inert surfaces for a wide range of salt concentrations, relative …

Selection of the liquid desiccant in a run-around membrane energy exchanger
… several possible liquid desiccants (aqueous solutions of LiCl, LiBr, MgCl2 and CaCl2) are investigated to find the most appropriate working fluid to be used in a run-around membrane energy exchanger (RAMEE). The liquid desiccant is one of the main components of the RAMEE and indirectly …

The Effect of Salt Splash on Nylon 6,6
… used for automotive applications, is that of salt splash, which commonly occurs during winter driving. This study looks at the effect of various salts (NaCl, KCl, CaCl2) on the thermal and mechanical properties of nylon when exposed to one and four molar aqueous salt solutions. It was found …

STUDIES ON COMPLEX FORMATION BY HEPARIN
… hexammine ion, Co(NH3)63+ seems to form a salt linkage with a disaccharide unit of heparin. Cobalt-heparin is insoluble in the usual solvents but is soluble in salt solutions of high ionic strength (0.6) and the cobalt ion can be removed from the heparin by dialysis in such salt solutions. …

TCAQ-based polymer for electrochemically mediated separations
… was quantified in low-concentration aqueous salt solutions. The polyvinyl ferrocene (PVF)//PTCAQ system displayed an ion adsorption capacity much higher than previously reported literature values for capacitive or redox deionization systems.

Studies into the release mechanisms of human placental lactogen in vitro
… incubating placental fragments in physiological salt solutions for short periods. The effect of test substances and different ionic environments on HPL release were tested to ascertain the roles of calcium ion and cyclic AMP in the release mechanism. 2. The HPL concentration of the incubation …

Influence of counter-ions on antifogging coatings
… silica nanoparticles were treated with salt solutions of monovalent and divalent cations. Refraction index of the films dropped significantly when treated with monovalent cations, and increased when treated with divalent cations. It has been found that the refraction index decrease in …

Effects of sodium chloride and sodium gluconate concentration on hydration behavior and water transport in the red-spotted toad, Bufo punctatus
… and rehydration rate in standing water or salt solutions in dehydrated Red-spotted toads (Bufo punctatus) were used to demonstrate that: (1) toads can distinguish among NaCl concentrations, (2) NaCl facilitates water uptake across the skin, and (3) transport of the chloride anion …
