In this study, several ZnO catalysts were prepared using different zinc sources as precursors. The different catalyst morphologies obtained were used to degrade photocatalytically a methyl orange (MO) dye solution, which was used to model wastewater pollution. The precursors, Zn(CH3COO)2, ZnCl2 and Zn(NO3)2, were individually added to a solution containing cetyltrimethylammonium bromide (CTAB) ...

Binary and ternary hybrid systems of ZnO possessing nanoparticle and nanorod morphologies on reduced graphene oxide (rGO) and rGO with Au nanoparticles are explored as photocatalysts and a comparative study of their photodegradation performance is presented. Various preparation methods such as solution phase and hydrothermal routes have been employed to produce rGO-ZnO hybrids and rGO-Au-ZnO hy...

Zinc oxide (ZnO) nanoparticles (NPs) have been widely used for food fortification, because zinc is essential for many enzyme and hormone activities and cellular functions, but public concern about their potential toxicity is increasing. Interactions between ZnO and biomatrices might affect the oral absorption, distribution, and toxicity of ZnO, which may be influenced by particle size. In this ...

We report on the characteristics of near-band-edge (NBE) emission and deep-level band from ZnO/Al2O3 and ZnO/ZnO core-shell nanorod arrays (NRAs). Vertically aligned ZnO NRAs were synthesized by an aqueous chemical method, and the Al2O3 and ZnO shell layers were prepared by the highly conformal atomic layer deposition technique. Photoluminescence measurements revealed that the deep-level band w...

Herein, we demonstrate a graphene based efficient UV photodetector by using vertically aligned ZnO 8 NWs on chemical vapor deposited graphene with and without a ZnO buffer layer. The effect of rapid 9 thermal annealing (RTA) on grapheneZnO thin film hybrid prior to the growth of ZnO NWs by physical 10 vapor deposition technique is investigated from the μRaman spectroscopy and high resolution ...

The simple self-aligned photolithography technique and laser interference photolithography technique were proposed and utilized to fabricate multiple-gate ZnO metal-oxide-semiconductor field-effect transistors (MOSFETs). Since the multiple-gate structure could improve the electrical field distribution along the ZnO channel, the performance of the ZnO MOSFETs could be enhanced. The performance o...

The crystalline form of 1-deoxy-D-tagatose, C6H12O5, is shown to be 1-deoxy-alpha-D-tagatopyranose; the absolute configuration is determined by use of D-lyxono-1,4-lactone as the starting material. The title compound crystallized as concomitant polymorphs from a mixture of ethyl actate and methanol. Although the melting points of the materials differ by 7 K, the molecular conformations are almo...

INTRODUCTION Septilin is an Ayurvedic preparation which contains antibacterial and anti-inflammatory principles. Septilin has been reported to stimulate phagocytosis. Cahu and Hirsh (1960) demonstrated the presence of an antibacterial protein (phagocytin) in the cytoplasmic granules of polymorphs. This protein of polymorphs has an antibacterial effect on both gram-positive and gram-negative org...

At 70 h of age, the neonate presented with diarrhea. Examination revealed an active infant with normal hydration. Investigations revealed: hemoglobin 17 g/dl; TLC 8,300/mm (60% polymorphs, 40% lymphocytes and band to total neutrophil count ratio of 0.33); micro ESR 1 mm/lst hour. Stool miscroscopy revealed numerous polymorphs. Blood culture was sterile and stool culture grew Escherichia coli se...
