This paper reports two new indium tin oxide (ITO)-based nanostructures, namely ITO@carbon core-shell nanowire and jagged ITO nanowire. The ITO@carbon core-shell nanowires (~50 nm in diameter, 1-5 μm in length,) were prepared by a chemical vapor deposition process from commercial ITO nanoparticles. A carbon overlayer (~5-10 in thickness) was observed around ITO nanowire core, which was in situ f...

objective(s): nanoparticles (nps) are known for their specific accumulation in the inflamed tissues of the colon and thus allow a selective delivery to the site of inflammation with minimum adverse effects. the main objective of this work is to attain mesalamine loaded chitosan nanoparticles as a carrier for oral delivery. methods: in this study, mesalamine loaded chitosan nanoparticles were pr...

Copper zinc tin sulfide (CZTS) is a promising material for harvesting solar energy due to its abundance and non-toxicity. However, its poor performance hinders their wide application. In this paper gold (Au) nanoparticles are successfully incorporated into CZTS to form Au@CZTS core-shell nanostructures. The photocathode of Au@CZTS nanostructures exhibits enhanced optical absorption characterist...

We investigate the transport properties of silicon nanowires coated with zinc sulfide nanoparticles. Silicon nanowires were prepared by metal assisted electro-less chemical etching technique. The diameter of nanowires varies from 30 to 300 nm and length was 30 mm. Zinc sulfide nanoparticles having diameter 30 nm were synthesized by co-precipitation method. The nanoparticles were then deposited ...

Abstract This study, reports on ozone catalytic oxidation of dimethyl sulfide; a major odor material waste water facilities. Xenon excimer lamp (XEL) was used for generation, and iodine compounds (I- IO3-) were utilized as catalyst. Three types activated carbon, carbon impregnated with sulfate (AC-I/S), (AC-I) without impregnation (AC) tested catalysts. Only AC-I/S had activity in the dynamic a...

High quality double-walled carbon nanotubes (DWNTs) were synthesized by decomposition of methane over cobalt (Co) nanoparticles supported on porous MgO nanoparticles. The growth was significantly influenced by catalyst concentration and MgO type. Catalysts with 2.5–5 wt% Co loaded MgO (pore size: 4 nm) efficiently grow DWNTs with diameters of 2–4 nm, high graphitization, clean surfaces, and cle...

Copper sulfide nanoparticles (CuS) were successfully synthesized by the pulsed plasma in liquid method, using two copper rod electrodes submerged in molten sulfur. Low electrical energy and no high temperature were applied for synthesis. Obtained CuS nanoparticles were then analyzed by means of X-ray diffraction, Low and High Resolution Transmission Electron Microscopy, Electron Diffraction, X-...

BACKGROUND The purpose of this study was to develop a novel silymarin-loaded solid nanoparticle system with enhanced oral bioavailability and an ability to provide excellent hepatic protection for poorly water-soluble drugs using Shirasu porous glass (SPG) membrane emulsification and a spray-drying technique. METHODS A silymarin-loaded liquid nanoemulsion was formulated by applying the SPG me...

a sensitive and simple method for simultaneous preconcentration of trace heavy metal ions in some cerealand vegetable samples has been reported. the method is based on the adsorption of cu2+, fe3+, zn2+ and pb2+on 2-(2-nitro-phenylazo)-naphthalen-1-ol (npn) loaded on activated carbon (ac). the adsorbed metals onactivated carbon were eluted using 3 ml 4 mol l−1 nitric acid. the influences of the...
