Cu2Se is a high ZT material consisting of cheap and earth abundant elements. Its thermoelectric performance mainly based on very low thermal conductivity associated with mobile atoms. This comes the drawback critical voltage, over which decomposes to elemental copper copper-deficient Cu2−xSe phase. Composites selenide graphite do not enhance voltage significantly as completely encapsulated by g...

Abstract In this paper, the charging characteristics of powder particles with different properties under DC discharge corona conditions were studied experimentally. The influence voltages and structures on charge-mass ratio was analyzed through ELPI measurement. experimental results show that far-field structure electrode can effectively charge materials like Graphite micro powder, copper sulfi...

In this study, powder technology was used to obtain Fe-SiC composites in which SiC particles act as precursors generate a large amount of turbostratic graphite dispersed the composite matrix. The selection alloy composition studied employing Thermo-Calc® software temperature and range for stabilization phase iron with high yield. extracted 2D were mineral oil order evaluate potential these lubr...

background: dermatoglyphics are the dermal ridge configurations on the digits, palms and soles. dermatoglyphic polymorphism results from the co-operation of genetic and environmental factors. the dermatoglyphic analysis is a valuable completion of initial diagnosis of some syndromes genetically determined. our objective was to assess dermatoglyphics study results against standard chromosomal an...

Due to the rising trend in 2-Dimensional material, graphene has gained a lot of interest recent past. Graphene is 2D carbon allotrope with high strength and improved mechanical, chemical, electrical properties. Despite being excellent properties among other types allotropes but still, use limited because its costly synthesis technique. In this research, cheap effective method adapted for prepar...

This study reports an integrated device of a lithium-ion battery (LIB) connected with Si solar cells. A Li(Ni0.65Co0.15Mn0.20)O2 (NCM) cathode and graphite (G) anode were used to fabricate the (LIB). The surface shape morphologies NCM powder characterized by field emission scanning electron microscopy (FE-SEM). structural properties determined X-ray diffraction (XRD) analysis. XRD patterns powd...
