  • Direct ethanol PEM fuel cells: The case of platinum based anodes 

    Song, S. Q.; Zhou, W. J.; Zhou, Z. H.; Jiang, L. H.; Sun, G. Q.; Xin, Q.; Leontidis, V.; Kontou, S.; Tsiakaras, P. (2005)
    PtSn/C catalysts were prepared by the direct decoration of Pt/C with Sn through a modified poly process. XRD results showed there existed obvious SnO2 in this catalyst, different from the PtSn/C prepared by co-precipitation, ...
  • Effect of channel width on the primary instability of inclined film flow 

    Vlachogiannis, M.; Samandas, A.; Leontidis, V.; Bontozoglou, V. (2010)
    A procedure is developed to detect the onset of interfacial instability in inclined film flows (with estimated accuracy better than 5%) and is used to show that the finite width of experimental channels stabilizes the ...
  • Nominally two-dimensional waves in inclined film flow in channels of finite width 

    Leontidis, V.; Vatteville, J.; Vlachogiannis, M.; Andritsos, N.; Bontozoglou, V. (2010)
    Traveling waves in inclined film flow in channels of finite width are never truly two-dimensional (2D) because of a long-range effect of sidewalls The present study documents the characteristics of the first waves that are ...
