In this study, SiO2 nanoparticles were successfully synthesized via sol-gel precipitation method and the effects of different parameters such as temperature, ethanol, ammonia and tetraethylorthosilicate (TEOS) contents based on water were investigated in a systematic way applying Taguchi experimental design method. It was found that, among all the investigated parameters, ethanol as a co-solven...
In this paper, we have described the size-controlled synthesis of gold nanoparticles based on the reduction of Au3+ (HAuCl4 ) using molybdophosphoric acid (H3[PMo12O40 ], HPMo) under UV-irradiation. In the process, HPMo plays the role of photocatalyst, reducing agent and stabilizer and propan-2-ol acts as a sacrificial agent. This method allows the synthesis of uniform hexagonal nanoparticles w...
The ethic of war has been always of special importance for the scholars of the field. In this paper, the common views of western philosophers have been surveyed and then, using Quranic verses and traditions, the view of Islam on ethical justifiability of initial holy war has been explained, and some questions in the field have been answered.
