P. KATHIRVEL1,*
Highly crystalline Tin oxide (SnO2) nanoparticles were directly synthesized from inexpensive metallic tin (Sn) powder by flame synthesis technique. The rapid melting and oxidation of Sn in a high temperature oxidative flame produce the crystalline and pure SnO2 nanoparticles, as evident from X-ray Diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM) analysis.The residence time and oxidation time was calculated using basic fluid dynamics equations. The particle size calculated by XRD analysis found to be 24 nm. The good stoichiometry of SnO2 nanoparticles were supported by Energy Dispersive X-ray Analysis (EDAX). The band gap of the SnO2 nanoparticles was calculated using Kubelka-Munk function and found to be 3.4 eV..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
