LiSmxMn2–xO4 samples were synthesized via co-precipitation technique. The structural properties of the synthesized materials were studied using X-ray diffraction analysis and it confirmed the cubic spinel structure for all the compounds. The lattice parameter of LiMn2O4 was observed to be 8.2347 Ǻ and it decreased with Sm3+ concentration, due to the shrinkage in cell volume aided by higher binding...
The applications of microwave processing of electrode materials for Li-ion batteries have been reviewed. This paper intends to insist at the advantages of the microwave processing and its credentials for commercialization. In order to achieve successive commercialization/industrial application, a systematic understanding of the microwave processing becomes imperative. In the advent of this, an extensive...
Ceria-stabilized zirconia (CSZ) thin films have been developed over Ni-based alloy substrate by vacuum evaporation method using an electron beam. X-ray diffraction (XRD) analysis of the film heat treated at different temperatures reveals monoclinic phase stabilization. Transmission measurements of the films annealed at different temperatures, in the wavelength region 300–1,100 nm, indicate that the...
The present work deals with the design, development, and implementation of an angle detector using n-ATO/p-PSi photovoltaic sensor. Nanoporous structures have been developed over p-type porous silicon wafers by anodization technique under optimized conditions. Photoluminescence studies of porous silicon show emission between 700 and 702 nm for the constant excitation at 350 nm, which illustrates that...
P-type porous silicon (PS) structure has been prepared by anodic electrochemical etching process under optimized conditions. Photoluminescence studies of the PS structure show emission at longer wavelengths (red) for the excitation at 365 nm. Scanning electron microscope investigations of the PS surface confirm the formation of uniform porous structure, and the pore diameter have been estimated as...
