tio2 thin films and ag/tio2 nanoparticles were prepared by cvd and plasma bombardment method. xrd results showed the presence of ag nanoparticles in tio2 matrix. sem image confirmed formation of ag nanoparticles. xps analysis was utilized to study the chemical state of the ag/tio2 nanostructure. statistical surface analysis revealed that since there is a linear relation between logarithmic diag...
one of the most serious kinds of hepatitis is hepatitis b. this condition is more common than aids, and is 100 time more contagious. in iran the most common cause of acute and chronic hepatitis, liver cirrhosis, and also hepatocellar carcinoma in adults, is hepatitis b. more than two billion people are infected and more than 350 million of individuals are carriers of this virus in the entire wo...
Ag-Cu solid solutions prepared via ball milling process were subsequently milled for 30 h and investigated by X-ray diffraction technique for Cu-20%Ag, Cu-3.64%Ag and Cu-80%Ag. It was noted that the solid solubility level increased by increasing initial solute content in composition. Results showed peak positions of silver and copper changed with milling time. By heating up to 700 K, ...
Silver toxicity and its fate in the environment are currently being debated and are important as challenging research topics. Even though there are several studies on its total content in soils, fractionation of Ag especially in calcareous soils has not been investigated. Therefore, to provide fundamental information on the chemical behavior of Ag in calcareous and noncalcareous soils, we studi...
