Copper oxide (CuO) nanostructures are of particular interest because of their interesting properties and promising applications in batteries, super capacitors, solar cells, gas sensors, bio sensors, nano fluids and catalysis. In Recent past, more efforts have been received to design materials with different properties which is dependent on morphology.  In this work cupric oxide nano flakes were...

Hierarchically porous silica monoliths with well-defined interconnected macropores and uniform spherical mesopores were spontaneously prepared by combining polymerization-induced phase separation with an epoxide-mediated sol-gel route without any complicated aging and drying and high-temperature heat treatment. The precise control of pore structures can be realized by using propylene oxide (PO)...

A novel technique for glucose sensing using collagen based thin film and zinc oxide (ZnO) nanoparticles, the Zinc Oxide Collagen Glucose Sensor (ZnOCGS) presented here. The Zinc oxide is synthesized using the two medium namely treating with 1.Ethanediol medium (Ethylene glycol) and 2.Water medium. It is characterized using the analytical techniques such as Fourier Transform infrared spectroscop...

Ag-Cu alloy catalysts for ethylene epoxidation have been shown to yield higher selectivity towards ethylene oxide compared to pure Ag, the unique catalyst employed in the industrial process. Previous studies showed that under oxidizing conditions Cu forms oxide layers on top of Ag. Using first-principles atomistic simulations based on density functional theory, we investigate the reaction mecha...

This paper reports on the use of nanoporous Pt-TiO2 thin films coated onto magnetoelastic sensors for the detection of ethylene, an important plant growth hormone. Five different metal oxide coatings, TiO2, TiO2+ZrO2, TiO2+TTCN(1,4,7Trithiacyclononane)+Ag, SiO2+Fe, and TiO2+Pt, each having demonstrated photocatalytic activity in response to ethylene, were investigated for their ability to chang...

A comparative investigation of the aggregation in aqueous solution of a poly(ethylene oxide)-poly(propylene oxide)poly(ethylene oxide) block copolymer (PEO-PPO-PPO) (Pluronic F127) with a polydimethylsiloxane-graft-polyether (PDMS-PEO) has been done. The spectroscopic parameters obtained from absorption spectra of the 4,4,5,5tetramethylimidazoline-1-oxyl-3-oxide-2-undecyl (TEMIDO-undecyl) and f...

This paper describes a strategy for producing hydrogen via steam reforming of ethylene glycol over supported nickel catalysts. Nickel plays a crucial role in conversion of ethylene glycol and production of hydrogen, while oxide supports affect product distribution of carbonaceous species. A plausible reaction pathway is proposed based on our results and the literature.
