      Structural features of ball-milled nanostructured K2Bi 8Se13 thermoelectric material 

      Lioutas, C. B.; Hatzikraniotis, E.; Ioannou, M.; Paraskevopoulos, K. M.; Kyratsi, Theodora (2011)
      In this work, K2Bi8Se13 material was ball-milled in order to develop nanostructures through the modification of structural features. Structural changes during ball-milling were followed by powder X-ray diffraction measurements, ...

      Thermoelectric properties of nanocrystalline PbTe synthesized by mechanical alloying 

      Papageorgiou, Ch; Hatzikraniotis, E.; Lioutas, Ch B.; Frangis, N.; Valassiades, O.; Paraskevopoulos, K. M.; Kyratsi, Theodora (2010)
      In this work, nanocrystalline lead telluride powder was synthesized from high-purity elements by mechanical alloying by means of a planetary ball-milling procedure. The milling medium was tungsten carbide, and the diameter ...
