      Thermal and chemical stability of hexagonal boron nitride (h-BN) nanoplatelets 

      Kostoglou, N.; Polychronopoulou, K.; Rebholz, Claus (2015)
      High-temperature properties of boron nitride platelets (200-800 nm in width and 30-50 nm in thickness) were systematically evaluated through thermogravimetric analysis (TGA) in combination with differential scanning ...

      Tribological properties of twin electron-beam evaporated Cr-N and Al-Cr-N coatings under laboratory sliding and drill experiments 

      Polychronopoulou, K.; Demas, N. G.; Rebholz, Claus; Polycarpou, A. A. (2008)
      The tribological behavior of substoichiometric Cr-N and Al-Cr-N coatings prepared by twin electron-beam evaporation at 450°C was studied. Al-Cr-N coatings with Al to Cr ratios in the range of 1-8 (and nitrogen concentrations ...

      Zn3N2nanowires: Growth, properties and oxidation 

      Zervos, Matthew; Karipi, C.; Othonos, Andreas S. (2013)
      Zinc nitride (Zn3N2) nanowires (NWs) with diameters of 50 to 100 nm and a cubic crystal structure have been grown on 1 nm Au/Al2O3via the reaction of Zn with NH3including H2between 500°C and 600°C. These exhibited an optical ...
