      Electron spectroscopic studies of nanocomposite PVD TiAlBN coatings 

      Baker, M. A.; Rebholz, Claus; Leyland, A.; Matthews, A. (2002)
      A range of TiAlBN coatings have been deposited by electron beam evaporation and the optimised composition exhibits a 150% improvement over single phase TiAlN coatings in drilling tests. The coatings have been analysed by ...

      Evaluating the microstructure and performance of nanocomposite PVD TiAlBN coatings 

      Baker, M. A.; Klose, S.; Rebholz, Claus; Leyland, A.; Matthews, A. (2002)
      Physical vapour deposition (PVD) TiAlBN coatings can exhibit excellent wear resistance, with optimised coating compositions demonstrating a 150% increase in lifetime compared to standard TiAlN coatings in wet-cutting drill ...

      Influence of grain size on ultrafast carrier dynamics in thin nanocrystalline silicon films 

      Lioudakis, Emmanouil E.; Othonos, Andreas S.; Nassiopoulou, Androula Galiouna; Lioutas, Ch B.; Frangis, N. (2007)
      The ultrafast carrier dynamics in thin nanocrystalline silicon films (10 and 20 nm thick) on quartz over a broad spectral range using optical pumping at a moderate fluence of 2.5 mJ cm2 were studied. The films were composed ...

      Nanostructural studies of PVD TiAlB coatings 

      Monclus, M. A.; Baker, M. A.; Rebholz, Claus; Stolojan, V.; Gibson, P. N.; Leyland, A.; Matthews, A. (2006)
      TiAlB coatings with different compositions were deposited by co-sputtering from TiAl and TiB2 targets onto AISI316 stainless steel substrates at a temperature of 170 °C. The stoichiometry and nanostructure have been studied ...

      Radioactivity and metal concentrations in marine sediments associated with mining activities in Ierissos Gulf, North Aegean Sea, Greece 

      Pappa, Filothei K.; Tsabaris, Christos G.; Ioannidou, Alexandra; Patiris, Dionisis L.; Kaberi, Helen G.; Pashalidis, Ioannis; Eleftheriou, George; Androulakaki, Effrossyni G.; Vlastou, Roza (2016)
      Marine sediment samples were collected from Ierissos Gulf, N Aegean Sea, close to the coastal mining facilities. Measurements of radionuclide and metal concentrations, mineral composition and grain size distribution were ...
