      Exothermic reaction characteristics of continuously ball-milled Al/Ni powder compacts 

      Hadjiafxenti, A.; Gunduz, I. E.; Kyratsi, Theodora; Doumanidis, C. C.; Rebholz, Claus (2013)
      Self-propagating reactions in compacted pellets of continuously low-energy ball-milled aluminium (Al) and nickel (Ni) powders at a composition corresponding to AlNi3 were investigated. The formation of a bi-modal structure ...

      IR reflectivity studies of mechanically alloyed PbTe nanocrystals 

      Hasapis, T. Ch; Papageorgiou, C.; Hatzikraniotis, E.; Kyratsi, Theodora; Paraskevopoulos, K. M. (Affiliation: Department of Physics, Aristotle University of Thessaloniki, 54123 Thessaloniki, GreeceAffiliation: Department of Mechanical and Manufacturing Engineering, University of Cyprus, 1678 Nicosia, CyprusCorrespondence Address: Hasapis, T. Ch.Department of Physics, Aristotle University of Thessaloniki, 54123 Thessaloniki, Greece, 2009)
      Nano-crystalline lead telluride powder was synthesized by mechanical alloying using a high-energy planetary ball mill. The broadening of the X-ray diffraction peaks vs ball milling time, indicates small crystalline size ...

      Synthesis of reactive structures by ball milling and ultrasonic consolidation 

      Hadjiafxenti, Anastasia G. (Πανεπιστήμιο Κύπρου, Πολυτεχνική Σχολή / University of Cyprus, Faculty of Engineering, 2013-01)
      Πηγές ενέργειας στη νανο- και στη μικο- κλίμακα έχουν ελκύσει το ενδιαφέρον ως πιθανά ικανά εργαλεία στη νανοκατασκευστική και μικροκατασκευαστική. Υπερλεπτά πολύστρωματικά υμένια (ΠΥ) χρησιμοποιούνται σαν νανοθερμικές ...
