Present investigation describes simple chemical synthesis of Bi2O3 loaded polypyrrole (PPy) composites are prepared by ex-situ approach. As prepared composites show good sensing performance towards liquefied petroleum gas (LPG). The sensing response of composites has been observed good dependence on loading concentration of Bi2O3 in PPy. Main achievement of present work is that the operating temperature (353 K) of composite (25 wt %) is found much below the auto-ignition temperature of LPG. Besides that composites exhibit good complex optical properties such as extinction coefficient, optical conductivity, real and imaginary dielectric constant..

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.
