Gallium nitride (GaN) – gallium oxide (Ga2O3) nano-composites were synthesized through ammonolysis of Ga2O3 powder, with or without the addition of multi-wall carbon nanotubes (MWCNT). Both synthesized nano-composites having rod-shaped structure, while addition of MWCNT had resulted in hollow-like interior with some cavity walls. Vibrational measurement revealed that both samples contained mixture of GaN-Ga2O3, with GaN being the dominant. Optical measurements showed a high level of defects present in both samples. Violet-blue bands (VBL) were observed in both samples. Sample with added MWCNT exhibited blue shift relative to that of without MWCNT, which properties may governed by the contents of nitrogen..

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.
