The mechanical properties of crystals were evaluated by mechanical testing. The fastest and simplest type of mechanical testing is hardness measurement. The Vickers microhardness studies have been carried out for L-Valine crystals grown by a slow evaporation technique over a load range of 10–100 g. The Vickers hardness number (Hv) was found to increase with the increase in load. The Meyer's index number ‘n’ was calculated from Hv and yield strength (σv). The Young's modulus was calculated using the Knoop hardness values. Hardness anisotropy has been observed in accordance with the orientation of the crystal.

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.
