The application of membranes in various industries is one of the most urgent needs to reduce energy consumption and environmental pollutants as well as low investment costs in the process of separation. In this investigation, the optimization of effective parameters for separation of gas mixture of CH4, CO2, O2 and N2 is studied by modified poly(4-met...

A photofuel cell comprising two photocatalysts TiO2 and Ag-TiO2 is demonstrated. The open circuit voltage, short circuit current, and maximum electric power of the PFC were 1.59 V, 74 μA, and 14 μW, respectively. The electron flow was rectified due to the Schottky barrier between TiO2 and Ag nanoparticles.

Inthiswork, Titanium dioxide (TiO2) nanostructures have beensynthesized via amicrowave assisted solvothermalmethod using titanium tetraisopropoxide (TTIP),polyvinylpyrrolidone(PVP) and Ascorbic Acid (AA) in ethanol. The mole ratio ofPVP/AA was found to be critical in determining the morphology and crystal phaseof the final product. PVP/AA mole ratio varied from 1 up to 1...

BACKGROUND Doxorubicin has a broad spectrum of anticancer activity, but its clinical application is limited due to serious side effects. The aim of this study was to explore a novel drug delivery system based on titanium dioxide (TiO(2)) nanoparticles for its potential role in enhancing the anticancer efficacy of doxorubicin while reducing its side effects. METHODS AND RESULTS Doxorubicin was...

Abstract Recently alcohol fuel cells has been increased consideration because of their environmental friendliness, high energy conversion efficiency and low emissions. Many effort have been made to improve the electro-oxidation performance of alcohols such as methanol, ethanol and propanol. In this work, a new method for ethanol oxidation based on core–shell titanium dioxide / carbon nanofib...

In this work firstly ZnO nanoparticles were synthesized via a simple precipitation method. At the second step titanium dioxide and silicon dioxide shell were synthesized on the core. For preparation ZnO-TiO2-SiO2 the sol product was calcinated at 500 ºC for 2h. Properties of the product were examined by X-raydiffraction pattern (XRD), scanning electron microscope (SEM) and Fourier transform inf...

Background This article presents an acoustically enhanced microfluidic mixer to generate highly uniform and ultra-fine nanoparticles, offering significant advantages over conventional liquid antisolvent techniques. Methods The method employed a 3D microfluidic geometry whereby two different phases - solvent and antisolvent - were introduced at either side of a 1 μm thick resonating membrane, ...
