Electrocatalytic production of ammonia from dinitrogen is considered as a sustainable alternative to the energy-demanding and pollutive Haber-Bosch process. A promising class materials for selective nitrogen reduction (NRR) corresponds transition-metal oxides given that these electrodes do not show high activity toward competing hydrogen evolution reaction. So far, density functional theory cal...

A method is presented that enables the template assisted electrochemical deposition of tens micrometer thick, compact and stoichiometric Bi2Se3 micropillars. This achieved by modifying acidic electrolyte contains 1 M HNO3 with potassium chloride salt introducing resting pulses during plating process. We demonstrate successful into photoresist templates mold diameters down to 30 µm thicknesses u...

optical modeling was applied for obtaining absorbance spectra and band gap values for different morphology of zno semiconductor. in optical modeling, the relative permittivity scalars of zinc oxide coral like nanorods were calculated using the bruggeman homogenization formalism. zno nano rods (zonrs) as a nucleus layer were fabricated on the indium tin oxide (ito) by chronoamperometry (ca) in a...
