By employing the first principles method of the full potential linearized augmented plane waves (FP-LAPW) approach based on density functional theory and Debye model the thermodynamic properties of 𝛼−𝐴𝑙2𝑂3 are investigated. The exchange correlation potential was calculated in framework of generalized gradient approximation (GGA). Through the quasi-harmonic Debye model, in which the phononic effects are considered, we have obtained successfully the thermodynamic parameters including the relative volume, heat capacity and volume expansion coefficient over a pressure range 0-70 Gpa and a wide temperature range of 0-2000 K..

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.
