System for evaluating effects of immersion in molten copper chloride salts on corrosion resistant coatings
Hydrogen, as one of the best alternative energy carrier candidates, is easier to sustain than fossil fuel. Hydrogen demand has significantly increased as a clean energy carrier. The Cu-Cl cycle is one of the capable thermochemical cycles which is supposed to develop hydrogen production. Since this …

OPTICAL BISTABILITY IN ZINC-SULFIDE AND ZINC-SELENIDE THIN-FILM INTERFERENCE FILTERS AND IN GALLIUM-ARSENIDE AND COPPER-CHLORIDE ETALONS (NONLINEAR).
Two-photon optical bistability in commercial thin-film interference filters with ZnS and ZnSe spacers is observed with switching times ≳ 200 μs. The accompanying drifting of the bistability loop in time and laser-induced "damage" indicate a thermal mechanism. The problem of water vapor absorption …

The effects of zinc source and supplemental copper on growth performance, carcass characteristics, and morbidity and mortality of growing-finishing pigs raised under commercial conditions
Zinc hydroxychloride and tribasic copper chloride are relatively new mineral sources that are claimed to have improved bioavailability relative to commonly used zinc sources such as zinc oxide. Both sources were evaluated in two studies that were carried out to determine the effects of zinc source …
