      The steam reforming of phenol reaction over supported-Rh catalysts 

      Polychronopoulou, Kyriaki; Costa, Costas N.; Efstathiou, Angelos M. (2004)
      The steam reforming of phenol reaction towards H2 production was studied in the 575-730°C range over Rh supported on CeO2, ZrO2 and SiO2 single metal oxides and various mixed metal oxides such as CeO2-SiO2, ZrO2-SiO2 and ...

      Underwater Robotic Welding of Lap Joints with Sandwiched Reactive Multilayers: Thermal, Mechanical and Material Analysis 

      Hussein, Aseel; Alkhoori, Ayesha; Zaabi, Abdelaziz Al; Stefanini, Cesare; Renda, Federico; Jaffar, Syed; Gunduz, Ibrahim Emre; Polychronopoulou, Kyriaki; Rebholz, Claus Georg; Doumanidis, Charalabos Constantinos (2018)
      Underwater welding using reactive materials pre-deposited at the junction surfaces as a self-contained, in-situ ignitable heat source mitigates external power and gas supply requirements. Consequently, lending itself to ...

      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. ...
