      Adsorption of nitrogen and water vapour by activated Nomex® chars 

      Freeman, J. J.; Tomlinson, J. B.; Sing, K. S. W.; Theocharis, Charis R. (1995)
      Fibrous activated carbons were prepared from Nomex® poly(m-phenylene isophthalamide), in the form of a commercially available woven textile. After carbonisation in nitrogen and activation in either carbon dioxide or steam ...

      Conservation laws and hierarchies of potential symmetries for certain diffusion equations 

      Ivanova, Nataliya M.; Popovych, R. O.; Sophocleous, Christodoulos; Vaneeva, Olena O. (2009)
      We show that the so-called hidden potential symmetries considered in a recent paper [M.L. Gandarias, New potential symmetries for some evolution equations, Physica A 387 (2008) 2234-2242] are ordinary potential symmetries ...

      A consistent velocity approximation for variable-density flow and transport in porous media 

      Albets-Chico, X.; Kassinos, Stavros C. (2013)
      Using a finite-volume nodal-based code, we introduce a new consistent numerical scheme for approximating the seepage velocity in variable-density flow in porous media. It has been known from previous works that the lack ...

      Fabrication of nanorods by metal evaporation inside the pores of ultra-thin porous alumina templates 

      Kokonou, M.; Rebholz, Claus; Giannakopoulos, K. P.; Doumanidis, C. C. (2007)
      Porous alumina has attracted a great deal of attention as a template material for the growth of nanowires and nanodots. Typically, the pores have a high aspect ratio, which forbids the use of evaporation techniques for ...

      Nanoporous activated carbon cloth as a versatile material for hydrogen adsorption, selective gas separation and electrochemical energy storage 

      Kostoglou, N.; Koczwara, C.; Prehal, C.; Terziyska, V.; Babic, B.; Matovic, B.; Constantinides, G.; Tampaxis, C.; Charalambopoulou, Georgia; Steriotis, T.; Hinder, S.; Baker, M. A.; Polychronopoulou, K.; Doumanidis, C. C.; Paris, O.; Mitterer, C.; Rebholz, Claus (2017)
      The efficient storage of energy combined with a minimum carbon footprint is still considered one of the major challenges towards the transition to a progressive, sustainable and environmental friendly society on a global ...

      Novel combustion synthesis of carbon foam‑aluminum fluoride nanocomposite materials 

      Kostoglou, N.; Gunduz, I. Emre; Isik, T.; Ortalan, V.; Constantinides, G.; Kontos, A. G.; Steriotis, T.; Ryzhkov, V.; Bousser, E.; Matthews, A.; Doumanidis, C. C.; Mitterer, C.; Rebholz, Claus (2018)
      The facile, rapid and bulk production of composite materials consisting of carbon nanostructures doped with metal-based compounds has been a significant challenge for various research areas where such types of materials ...

      On the use of swellable polymers as structure directing scaffolds in porous solids design 

      Papatryfonos, Charalambos A. (Πανεπιστήμιο Κύπρου, Σχολή Θετικών και Εφαρμοσμένων Επιστημών / University of Cyprus, Faculty of Pure and Applied Sciences, 2019-07)
      Ο στόχος της παρούσας διδακτορικής διατριβής ήταν η χρήση διογκώσιμων πολυμερικών πλεγμάτων ως ικριώματα κατεύθυνσης δομής για την σύνθεση μεσοπορωδών οξειδίων μετάλλων. Συγκεκριμένα, κατά την διάρκεια αυτής της ερευνητικής ...
