Plastic encapsulated microcircuits with aluminum triple track structures were exposed to mixed flowing gas conditions to simulate and accelerate possible environments during long-term storage. No increase in resistance was measured and no corrosion products were observed after 800 h of accelerated exposure. Further experimentation indicated that chloride gas reacts with surface moisture in micr...

Chloride homeostasis has a pivotal role in controlling neuronal excitability in the adult brain and during development. The intracellular concentration of chloride is regulated by the dynamic equilibrium between passive fluxes through membrane conductances and the active transport mediated by importers and exporters. In cortical neurons, chloride fluxes are coupled to network activity by the op...

Leachate and groundwater samples were collected from Vendipalayam, Semur and Vairapalayam landfill sites in Erode city, Tamil Nadu, India, to study the possible impact of leachate percolation on groundwater quality. Concentrations of various physicochemical parameters including heavy metals (Cd, Cr, Cu, Fe, Ni, Pb, Fe and Zn) were determined in leachate samples and are reported. The concentrati...

The aim of this study was to investigate the sub-lethal effects Lead Chloride (PbCl2) on blood indices, liver enzymes, cytochrome P450 gene expression in common carp. For this purpose, Fish with a mean weight of 7 33±0.33 g were prepared and divided into 3 treatments and a control group and exposed to effective concentrations (0.05, 0.15, 0.25 mg / l) of sublethal toxicity for a period of 14 da...

Cesium lead iodide possesses an excellent combination of band gap and absorption coefficient for photovoltaic applications in its perovskite phase. However, this is not its equilibrium structure under ambient conditions. In air, at ambient temperature it rapidly transforms to a nonfunctional, so-called yellow phase. Here we show that chloride doping, particularly at levels near the solubility l...

we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...

Background & Aims: Humic acid is a major agent in trihalomethanes (THMs) formation during chlorination process, which are known as carcinogens. The aim of this study were to investigate the removal of humic acid by three coagulants including PACl, alum and ferric chloride from water sources and their  effect on zeta potencial. Materials & Methods: This study was conducted &nbsp...

Partially purified thromboxane synthase from human platelets converted prostaglandin Gz to two products. These were transformed to 12-hydroxy-5,8,10heptadecatrienoic acid and thromboxane B2 by stannous chloride reduction and to 12-keto-5,8,10-heptadecatrienoic acid and 15-ketothromboxane Bz by lead tetraacetate dehydration. Trapping with methanol after short incubations of substrate with enzy...
