Long-Term Conductivity Stability of Electrolytic Membranes of Scandia Stabilized Zirconia Co-Doped with Ytterbia.

The effect of high-temperature aging for 4800 h at a temperature of 1123 K on the crystal structure and the conductivity of (ZrO)(ScO)(YbO) and (ZrO)(ScO)(YbO) single-crystal membranes were studied. Such membrane lifetime testing is critical to the operation of solid oxide fuel cells (SOFCs). The crystals were obtained by the method of directional crystallization of the melt in a cold crucible.

Medicinal herbs and phytochitodeztherapy in oncology.

Application of clinical phytology in treatment of oncology diseases was limited by intensive development of chemical pharmaceuticals and surgery. The authors had set the task to develop the computer database for phytotherapy application. The database included full information on patient's clinical status (identified diseases, symptoms, syndromes) and applied phytotherapy treatment.
