In this work, we report the preparation of nanostructured electrodes based on dense arrays vertically-aligned copper (Cu) nanowires (NWs) to be subsequently covered by cadmium telluride (CdTe) thin films, with great potential used within “substrate”-type photovoltaic cells AII-BVI heterojunctions. particular, multi-step protocol presented here involves an electrochemical synthesis procedure a s...

Common II-VI compound semiconducting materials are stable thermodynamically with zincblende phase, while the II-O materials such as zinc oxide ZnO and beryllium oxide BeO are stable with wurtzite phase, and cadmium oxide CdO and magnesium oxide MgO are stable in rocksalt phase. This phase disharmony in the same material family laid a challenge for the basic physics and in practical applications...

Eight sodium dithiocarbamates (NaS2CNR1R2) have been examined as antidotes for acute cadmium intoxication. While all of them possess an ability to increase survival when given to mice 2 hr after a lethal (greater than 99%) intraperitoneal injection of 10 mg/kg of CdCl2 X 2.5H2O, their effects on the organ distribution of cadmium vary considerably. It has been possible to show that the accumulat...

The high concentrations of cadmium recorded in the digestive gland of cephalopods from various temperate and subpolar waters suggest that these molluscs have developed efficient cadmium detoxification mechanisms. The subcellular distribution of cadmium in the digestive gland cells was investigated in seven cephalopod species from the Bay of Biscay (France) and the Faroe Islands. In most species...

Due to unique physico-chemical properties of –SH moiety thiols comprise wide group of biologically important compounds. A review devoted to biological functions of glutathione and phytochelatins with literature survey of methods used to analysis of these compounds and their interactions with cadmium(II) ions and Murashige-Skoog medium is presented. For these purposes electrochemical techniques ...

Using EXAFS, we investigated the changes in the local structure of Cd(II) complexes formed with a series of low-molecular-weight thiols at different thiol/cadmium stoichiometries. For dilute solutions, a comparison of theoretical and experimental standards proved the latter approach superior. The number of bound oxygen atoms decreased while the number of sulfur atoms increased as the thiol/cadm...

We use a first-principles rational-design approach to demonstrate the potential of semiconducting half-Heusler compounds as a previously unrecognized class of piezoelectric materials. We perform a high-throughput scan of a large number of compounds, testing for insulating character and calculating structural, dielectric, and piezoelectric properties. Our results provide guidance for the experim...

Problem statement: Cadmium is one of the most dangerous occupational and environmental toxins. It is found in drinking water, atmospheric air and even in food. Cadmium is reported to be very toxic to biological systems. Until now in treating intoxication with this metal, chelating Compounds have been used, burdened with numerous undesirable symptoms. For this reason, many researches are carried...
