    Abstract: Two different three-dimensional nanostructured cobalt/nickel layered double oxides grown on Ni foam (NF) were synthesized through one-step (NF/NiCo2O4) and two-step (NF/Co3O4/NiO) solvothermal method for flexible and high performance supercapacitor applications. The as-prepared composites have been systematically characterized by powder X-ray diffr... Show More

    Abstract: This paper presents the analysis of the h-parameter of a single stage small signal transistor amplifier using two-port network. This is motivated by the need to have the rudimentary knowledge of the h-parameter transistor analysis model and to demonstrate its equivalence in the three configuration of the transistor. In this analysis, it was borne i... Show More

    Abstract: YAG (Y3Al5O12)-Al2O3-Pt composite TBCs have been prepared on Ni-based superalloy (0.1% C, 12% Co, 6.5% Cr, 6.2% Al, 5% W, 1% Mo, 1.5% Hf, 6.5% Ta, 0.01% B, balance Ni, wt.%) by cathode plasma electrolytic deposition (CPED). As polyethylene glycol (PEG) is added in solution, the spark ignition current density is reduced significantly, and CPED would... Show More
