Résumé :
Copper compounds are widely used as impregnants that enhance the removal of HCN by carbon-based filter media. The reaction mechanism involved is poorly understood. In this study, we have followed the reaction of HCN with pristine copper, copper oxide (CuO and Cu2O) and copper@copperoxide (Cu@Cu2O) core–shell nanoparticles of well-defined size and composition. We have established a cooperative reaction mechanism where both the copper oxide shell and copper core are required for the chemisorption of HCN onto copper nanoparticle impregnants. The suitability of copper@copperoxide nanoparticles as impregnants for the removal of HCN in respirator canisters is discussed.

Résumé :
The discovery of high transition temperature, Tc, superconductivity in copperoxide-based ceramics by Bednörz and Miiller, and the subsequent increase in Tc above the boiling point of liquid nitrogen (77 K), renewed interest in employing superconducting thin films in high-speed, low-power electronic device applications (e.g., compact high-quality factor filters, delay lines, and Josephson elements for high-speed, low-power switching). However, realization of these benefits requires well-controlled, reliable superconducting thin film technology which addresses not only the growth of superconducting thin films, but also the development of a multilayer device technology encompassing materials with metallic, semiconducting, and insulating properties.

Résumé :
Oxides exhibit most of the interesting phenomena known to occur in solid-state systems. As a class of materials they may be richer in phenomenology than any other comparable class. Oxides can be insulators, semiconductors, or metals. The copperoxide-based compounds we have studied are superconductors with the highest critical temperatures. In some oxides, electrons manifest simple single-particle transport properties, with a high mobility; in others, they show strongly correlated behavior resulting in a Mott-Hubbard transition, localization, and charge- or spin-density waves. In some oxides, electron-phonon coupling leads to polaronic transport. Others show collective states such as magnetism; in some there are large local magnetic moments that can couple to form ferromagnetic or antiferromagnetic phases that exist up to high temperatures. Yet others have large nonlinear dielectric and optical properties. In fact, it would seem there is very little that some such oxide couldn't do for or to the experimenter.

Résumé :
In this study, stable copper nanoparticles were synthesized by using Aloe barbadensis leaf extracts. The present study tracing of an object is a green synthesis of copper nanoparticles by the interaction of leaf extract and copper salt and its azo dye (congored) degradation efficiency. The characterization of copper oxide nanoparticles were performed by XRD, SEM, FTIR, UV spectroscopy. The XRD analysis showed that average particle size was between 5-30nm by scherrer equation. The shape of the copper nanoparticles was spherical and cubic. The EDX of synthesized nanoparticles confirmed copper content 68%. UV spectrophotometer analysis confirms peak of the copper nanoparticles between 200-400nm. The effect of variables like concentration, time, PH, adsorbent dosage also examined in this present study on % degradation of dye. It was noted that maximum dye removal occured at PH= 4, maximum concentration of adsorbent 1mg/l, maximum time for dye degradation 120 mint. The nanoparticles removed 70% of congored dye from solution at optimum condition of reaction parameters.The kinetics of pseudo second order is followed by adsorption process.The calculated sum of square .012 and r2 =.980 were analyzed. Langmuir isotherm model fit best and straight line graph drawned with r2 value .991 and probability 1.6E-5. This showed that copper oxide nanoparticles have efficient capacity of azo dye degradation.
