A simple analytical system using the light scattering (LS) method has been developed in order to investigate phase transition temperatures of liquid crystals (LC). The changes of the intensity of the transmitted light through a sample were measured as a function of the temperature. All the studied LC showed appreciable changes in the transmitted intensity at the phase transition temperature. The transition temperatures determined by the LS method were identical to those obtained by differential scanning calorimetry (DSC).

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.
