In this experimental research the adsorption and photocatalytic properties of silica nanoparticles were used to disinfection water against the gram-negative Escherichia coli bacteria. Silica nanoparticles were synthesized by modified Stober method and characterized. TEM image shows that the prepared nanoparticles were spherical with 20-30 nanometers diameter and 4.25 eV bandgap energy. The disc diffusion test […]
AbstractIn this study, Al2O3/Pd(NO3)2/zeolite composite films have been fabricated by roll coating method and characterized by X-ray diffraction, energy-dispersive X-ray spectroscopy and field emission scanning electron microscopy. The gas adsorption was tested in an experimental setup by a continuous gas analyzer KIMO KIGAZ 210 at constant temperature and pressure (32 °C and 1.5 bar) and as a […]
Thermal plasma treatment is considered as a suitable alternative for the treatment of highly-hazardous wastes such as industrial, radioactive and medical waste. Therefore, a Plasma-Gasification-Melting (PGM) system for treatment of Chemical and Pharmaceutical Wastes (CPW) with a capacity of 1 ton/day is developed using a melting and gasification furnace equipped with two non-transferred thermal plasma […]
Impacts of the liquid environment on the characteristics of pulsed laser ablation (PLA) synthesized tungsten (W) nanostructures have been investigated. High purity W target was irradiated by the fundamental wavelength of a Q-switched Nd:YAG laser of 7 ns pulse width and 1 J/cm2 laser fluence in different liquid environments including distilled water, ethanol, acetone, and […]
