copper thin films with nano-scale structure have numerous applications in modern technology.  in this work, cu thin films with different thicknesses from 50–220 nm have been deposited on glass substrate by dc magnetron sputtering technique at room temperature in pure ar gas. the sputtering time was considered in 4, 8, 12 and 16 min, respectively. the thickness effect on the structural, morpholo...

In recent years, the nanoscale zero-valent iron (NZVI) particles have been used successfully for the degradation of hydrocarboncompounds and remediation of other pollutants. Nevertheless, as far as we know, there is no specific study on the improvement of thegeotechnical properties of contaminated soils with hydrocarbon compounds by NZVI. This study used NZVI particles to remove gasoil in a cla...

Removal of As(V) using nanoscale iron particles was examined in batch reactors. Nanoscale iron particles, utilizing zerovalent iron with a diameter less than 100 nm as reactive materials, have been demonstrated to effectively remediate a wide variety of common environmental contaminants. In this study, characterization of nanoscale iron particles and their corrosion products was conducted using...
