In this research for the first time, SrCrO4 nanoparticles were prepared using sol–gel procedure in which amino acid was used as stabilization agent. Different amino acids were used as capping, stabilizer, or reduction agent. In this regard, the eff
The use of social media websites and applications has become very popular and people share their photos on these networks. Automatic recognition and tagging of people's photos on these networks has raised privacy preservation issues and users seek me

Hummer’s method which uses concentrated acid and oxidant agents, still is the most productive procedure for production of graphene oxide (GO). However, the reduction of the prepared GO sheets to the reduced graphene oxide (rGO) is the main problem
