In Situ Ni-Doped Co3O4 Nanostructure: An Efficient Electrocatalyst for Hydrogen Evolution,ifferent weight% (1, 3, 5, 7 and 10%) of Ni that demonstrates efficient electrocatalysis towards hydrogen evolution reaction (HER), in 1M KOH solution. The Ni doped Co.O. were synthesized using cobalt nitrate hexahydrate {Co(NO.)..6H.O}, nickel nitrate hexahydrate {Ni(NO.)..6H.O}and citric acid {C.H

Aerodynamic Performance Enhancement and Optimization of a H-rotor Vertical Axis Wind Turbine,rucial one. So, in this research study, an attempt is made to incorporate three such aerofoils like DU 06-W-200, NACA 0015, NACA 64-415. These aerofoils exhibit varied properties viz. camber, chord length and thicknesses, which have variable effects on the performance of the wind turbine. The aerofo

Fabrication of Dye-Sensitized Solar Cell Based on Natural Dye Sensitizer and ZnO Nanoflower Photoan process. This one is the least inexpensive and more effective among all new photovoltaic technologies, and the material used in this is also plentiful and relatively nontoxic. This paper emphasizes the fabrication of photoanode based on ZnO nanoflowers and carotenoid natural dye sensitizer. Nanostr
