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
… concerning 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 …

TCAQ-based polymer for electrochemically mediated separations
… performance 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.

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 …

Hybrid organic-inorganic pervaporation membranes for desalination
… independent of the concentration of the salt feed water. The pervaporation process combines the evaporation of volatile components of a mixture with their permeation through a nonporous polymeric membrane under reduced pressure conditions. In desalination applications, pervaporation has …

The Role of Fluids in Geological Processes
… composition on the critical P-T-X properties of aqueous salt solutions approximated by the H₂O-NaCl-KCl-CaCl₂ system. The results indicate a systematic variation in critical properties as a function of composition over the range of P-T-X studied. A technique for analyzing individual H₂O-CO₂ …

In-Plane Conductance of Thin Films as a Probe of Surface Chemical Environment: Adsorbate Effects on Film Electronic Properties of Indium Tin Oxide and Gold
… Modulating the double layer with varying aqueous salt solutions also affects ITO conductance, though not to the same degree as strong Bronsted acids and bases. Solvents of varying dielectric constant and proton donating ability (ethanol, dimethylformamide) decrease ITO conductance relative …

MODELLING CRYSTALLIZATION FOULING IN LIQUID-TO-AIR MEMBRANE ENERGY EXCHANGERS
… separation processes to separate water from an aqueous solution. Liquid-to-air membrane energy exchangers (LAMEEs) use membranes to control humidity and temperature in heating, ventilation and air-conditioning (HVAC) systems. A semi-permeable hydrophobic membrane is used in LAMEEs to separate an …

Twofold switchable block copolymers based on new polyzwitterions
… their solubility in water, deuterated water, and aqueous salt solutions. These poly(sulfobetaine)s show thermoresponsive behavior in water, exhibiting upper critical solution temperatures (UCST). Phase transition temperatures depend notably on the molar mass and polymer concentration, and are much …

Measurements and modeling of deposition rates from near-supercritical, aqueous, sodium sulfate and potassium sulfate solutions to a heated cylinder
… therefore often injected into the reactor. The salts that are formed upon neutralization (sulfates, chlorides, phosphates, etc.) have low solubility in supercritical water (SCW) and consequently precipitate as solid phases. These salts can form agglomerates and coat internal surfaces, leading to …
