This study highlights biohydrogen production enrichment through NiO and CoO nanoparticles (NPs) inclusion to dark fermentation of rice mill wastewater using Clostridium beijerinckii DSM 791. (~26 nm) (~50 NPs were intrinsically prepared via facile hydrothermal method with polyhedral morphology high purity. Dosage dependency studies revealed the maximum characteristics for 1.5 mg/L concentration...

An ethylene-glycol (EG) mediated self-assembly process was firstly developed to synthesize micrometer-sized nanostructured Mg-doped Fe3O4 composite oxides to decompose hexachlorobenzene (HCB) at 300°C. The synthesized samples were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, energy dispersive X-ray spectroscopy and inductively coupled plasm...

The selective hydrogenation of fatty acids to fatty alcohols can be achieved under moderate conditions (180 °C, 30 bar H2) by simultaneously supporting copper and iron oxides on mesoporous silica nanoparticles. The activity of the cosupported oxides is significantly higher than that of each supported metal oxide and of a physical mixture of both individually supported metal oxides. A strong int...

In this work, the effect of surface hydrogenation of different metal oxides, in particular molybdenum and tungsten oxides widely used to enhance hole extraction and zinc and titanium oxides widely used to enhance electron extraction, on the nanomorphology and the charge generation efficiency of polymer blend solar cells is investigated. It was found that photoactive layers based on blends using...

IO N Transparent electrodes are critical components of thin-fi lm optoelectronic devices such as displays and thin-fi lm solar cells. Most high-performance transparent conducting fi lms in use today are composed of sputtered metal oxides. [ 1 , 2 ] These fi lms can have sheet resistances under 20 Ω − 1 with 90% transmission when deposited at a high temperature onto glass and resistances increas...

The highly ordered mesoporous silica media, SBA-15, was synthesized and incorporated with iron, aluminum, and zinc oxides using an incipientwetness impregnation technique. Adsorption capacities and kinetics of metal-impregnated SBA-15 were compared with activated alumina which is widely used for arsenic removal. Media impregnated with 10% of aluminum by weight (designated to Al10SBA-15) had 1.9...

Present work demonstrates a detail simulation results on enhanced generation of localized surface plasmon resonance (LSPR) field condition in a periodically varying height metal nanopillars. This simulation work has been carried out using COMSOL Multiphysics software. LSPR field condition study in metal nanostructure is important for different fields of applications which include chemical and b...
