FABRICATION STRUCTURE AND PROPERTIES OF NANOSTRUCTURED CERAMIC MEMBRANES

We fabricated polycrystalline La-doped CaMnO3ceramics by the conventional solid state reaction, andinvestigated the effect of La substitution on the hightemperature thermoelectric properties. Our resultsindicate that all La-doped CaMnO3 samples shownegative Seebeck coefficients, indica[r]

The semiconductor diode laser chips AlGaAs of the matrix structure (linear bars arrays structure), having an output opticalpower of 2W were packaged at the semiconductor laser labrotary - Institute of Materials Science. We have studied some its properties such as: the temperature dependence of laser[r]

2.4.7. Differential scanning calorimetry (DSC)The determination of glass-transition temperature (Tg) to assessthe interfacial bonding was carried out on a STARe system differential scanning calorimeter (Mettler-Toledo, Switzerland). Thecurves for samples (3e6 mg) were obtained by heating samp[r]
