      Synthesis of nanoporous graphene oxide adsorbents by freeze-drying or microwave radiation: Characterization and hydrogen storage properties 

      Kostoglou, N.; Tzitzios, V.; Kontos, A. G.; Giannakopoulos, K.; Tampaxis, C.; Papavasiliou, A.; Charalambopoulou, Georgia; Steriotis, T.; Li, Y.; Liao, K.; Polychronopoulou, K.; Mitterer, C.; Rebholz, Claus (2015)
      In the present work, we synthesized and systematically characterized two novel graphene-based nanomaterials, a chemically reduced graphene oxide (GO) sponge and a microwave-exfoliated GO. Textural properties were determined ...

      Tribological behavior of CrN and Al-Cr-N coatings 

      Demas, N. G.; Polycarpou, A. A.; Polychronopoulou, K.; Rebholz, Claus (Affiliation: Department of Mechanical Science and Engineering, University of Illinois at Urbana-Champaign, Urbana, IL 61801, United StatesAffiliation: Department of Mechanical and Manufacturing Engineering, University of Cyprus, 1678, Nicosia, CyprusCorrespondence Address: Demas, N. G.Department of Mechanical Science and Engineering, University of Illinois at Urbana-Champaign, Urbana, IL 61801, United States, 2009)
      The tribological behavior of CrN and Al-Cr-N coatings prepared by twin electron-beam evaporation at 450°C was investigated. The composition, structure, mechanical and tribological properties of the coatings were determined ...

      Water-gas shift reaction on Pt/Ce1- xTixO 2-δ: The effect of Ce/Ti ratio 

      Petallidou, Klito C.; Polychronopoulou, Kyriaki; Boghosian, Soghomon; Garcia-Rodriguez, S.; Efstathiou, Angelos M. (2013)
      Pt nanoparticles (1.2-2.0 nm size) supported on Ce1-xTi xO2-δ (x = 0, 0.2, 0.5, 0.8, and 1.0) carriers synthesized by the citrate sol-gel method were tested toward the water-gas shift (WGS) reaction in the 200-350 C range. ...

      X-Ray diffraction investigations of magnetron sputtered TiCN coatings 

      Schneider, J. M.; Voevodin, A.; Rebholz, Claus; Matthews, A.; Hogg, J. H. C.; Lewis, D. B.; Ives, M. (1995)
      X-ray diffraction measurements were performed on titanium carbonitride coatings produced in an electron enhanced, unbalanced magnetron system. The films were deposited onto AISI 316 stainless steel substrates with an argon ...
