Abstract
The prodigious X-ray flux of synchrotron radiation has proved an enormous boon in studies of the physicochemical properties of biological liquid crystals, in particular lipids. Herein is described the use of synchrotron based time-resolved X-ray diffraction (TRXRD) in the development of two new methods of collecting mesophase information for temperature—composition phase diagram construction which are considerably more efficient and information-dense than conventional methods. An interesting spin-off of one of these methods is the ability to measure the mutual diffusion coefficient of water in a contiguous series of lyotropic mesophases. Simultaneous calorimetry and TRXRD facilitates the direct measurement of correlated thermal and structural events in systems under identical conditions of thermal history.
