TiO2 as a photocatalyst has been widely investigated and applied in many fields such fuel cells, sterilization, environmental decontamination. Some efforts, operation parameters, synthesis techniques, improvements by doping have made to improve its performance. To with high photocatalytic activity for purification, the most important step is know about methods parameters conditions that lead pr...
Application of microbial fuel cells (MFCs) to wastewater treatment for direct recovery of electric energy appears to provide a potentially attractive alternative to traditional treatment processes, in an optic of costs reduction, and tapping of sustainable energy sources that characterizes current trends in technology. This work focuses on a laboratory-scale, air-cathode, and single-chamber MFC...
introduction: the purpose of this work was to study the ability of mri normoxic polymer gel dosimetry for evaluating the dose distribution in hdr brachytherapy of esophagial cancer at imam reza brachytherapy center (mashhad, iran). materials and methods: initially, 2liters of normoxic gel (magic) was fabricated and then poured into 12 calibration test tubes and placed in a perspex walled phanto...
The needle lift and return timing of a CRDI (common rail direct injection) injector were investigated using an accelerometer and the Bosch injection rate measurement method. The Bosch method was used to measure the fuel injection rate shape when fuel was injected with several patterns. An accelerometer was mounted on the outside of the injector to catch the needle lift and return timing of the ...
The effect of Nickel doped Cobalt ferrite nano particles Ni0.2CoxFe2-x04(x=0.1, 0.2, 0.3, 0.5) Created by sol-gel auto combustion technique using citric acid as fuel. single phase cubic structure form confirm the XRD. crystalline size calculated FWHM (311) plane Scherer’s formula. typicalsize sample varies in order regime. structural and lattice parameter were obtained XRD data. surface morphol...
There are several obstacles to the commercialization of PEM fuel cells. One of the reasons is that the presence of carbon monoxide (CO) in the reformatted fuel, even at a very small scale, decreases the fuel cell performance. The aim of this paper is to investigate the effect of CO in reformatted fuel on PEM fuel cell performance. For this purpose, a steady state, one-dimensional and non-isoth...
