A promising technique for the preparation of La(OH) 3 mesopo rous nanotubes and chain shaped nanofibers, which are obtained by calcination of electrospun polyvinyl pyrrolidone (lanthanum nitrate composite nanofibers (CNFs) at different temperatures, is presented. The prepared samples are characterized by therm ogravimetry and differential thermal analysis, X-ray diffractometry, scanning electron microscopy and Fourier transform infrared spectrometry. The CNFs are amorphous and the surface is smooth with a diameter of 13 µm. Mesoporous La(OH)3 nanotubes, formed by the nanoparticles, are obtained at 600 ºC, while chain shaped La(OH)3 nanofibers are obtained at 800 ºC. The La(OH) 3 nanotubes/ nanofibers have a diameter of 500 800 nm and are hexagonal with space group P63/m. A process for the formation of the La(OH)3 containing nanotubes and nanofibers is proposed..

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.
