WAQAS MAHMOOD1,*
In this paper the vibrational bands in phonon dispersion, heat capacity and the Debye curve are presented. An interesting thing is to compare for graphite, the simulated with the measured heat capacity within the temperature range from 100 to 350 K in a simple experiment. The Cambridge Serial Total Energy Package (CASTEP), a density functional theory based software is used for the theoretical calculations. The experimental heat capacity is determined in an experiment where a solid evaporates the mass of liquid nitrogen. It is illustrated for the graphite sample..

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.
