      Liquid-crystalline phase behavior in a zwitterionic tetraazapentacene 

      Riley, A. E.; Mitchell, G. W.; Koutentis, Panayiotis Andreas; Bendikov, M.; Kaszynki, P.; Wudl, F.; Tolbert, S. H. (2003)
      A 5,7-dioctadecylquinoxalinophenazine zwitterion 1 has been investigated to determine its thermal phase behavior. A combination of differential scanning calorimetry (DSC), variable temperature low- and high-angle X-ray ...

      Measurement of liquid crystal film thickness using interferometry 

      Kossivas, F.; Kyprianou, Andreas (2010)
      Thickness measurements of thin films having thickness less than 1 µm are difficult to obtain by an interferometer. These difficulties arise from the overlap of the fringes from the upper and lower surfaces of the thin ...

      Modelling study of liquid crystals orientation in the presence of corrosion potential 

      Kossivas, P.; Kyprianou, Andreas (2010)
      The anchoring and orientation of liquid crystal (LC) molecules are influenced by several parameters. This paper presents theoretical work that aims to explain how surface changes and potential due to corrosion, affect the ...

      Nematic liquid crystal film in the presence of corrosion as a novel method for corrosion sensing 

      Kossivas, Fotios (Πανεπιστήμιο Κύπρου, Πολυτεχνική Σχολή / University of Cyprus, Faculty of Engineering, 2012-01)
      Όπως είναι γνωστό, η ανάγκη για την ανίχνευση της οξείδωσης είναι σημαντική αναλογιζόμενοι το υψηλό οικονομικό κόστος, τους ανθρώπινους τραυματισμούς και την μόλυνση που διεθνώς αντιμετωπίζεται κάθε χρόνο λόγω της ύπαρξης ...

      Thin liquid crystal film for corrosion sensing 

      Kossivas, F.; Kyprianou, Andreas (2008)
      The anchoring energy of Liquid Crystals (LCs) is influenced by several parameters. Many scientists have exploited LCs anchoring in order to develop several LC based optical sensors. This paper proposes and proves a new ...
