Single crystals of undoped LiWO and LiWMoO: formation enthalpies, heat capacity in the temperature range 320-997 K.

The LiWO single crystal was first grown by applying the Czochralski technique with weight control and low-temperature-gradients. A single crystal of LiWO is one of the perspective materials for researching rare events. The heat capacity for a LiWMoO single crystal has been determined by DSC calorimetry in the temperature range 320-997 K for the first time.

Thermochemistry of Gd2BaCuO5 and LuBa2Cu3Ox.

Solution calorimetry, using 6.0 M HCl as a solvent, is used to study the thermochemistry of Gd2BaCuO5 and the high-temperature superconductor LuBa2Cu3O6.92.
