      Control of the morphology of crystalline calcium hydroxide 

      Theocharis, Charis R.; Pashalidis, Ioannis; Jordan, Stephanie L.; Gray, A. C.; Yeates, D. (2001)
      The reaction of solid calcium hydroxide with liquid or gaseous methanol, ethanol and toluene, and the effect this has on the surface properties of the solid was examined, as well as the modification of crystal habit by the ...

      Durability performance of self-compacting concrete 

      Kanellopoulos, Antonios; Petrou, Michael F.; Ioannou, Ioannis (2012)
      Although self compacting concrete (SCC) is currently used in many countries, there is a fundamental lack of the intrinsic durability of the material itself. This article presents the outcomes from a research program on ...

      The preparation and adsorptive properties of ammonia-activated viscose rayon chars 

      Tomlinson, J. B.; Freeman, J. J.; Theocharis, Charis R. (1993)
      Viscose rayon chars have been activated in ammonia under varying conditions in order to investigate whether the presence of N-containing groups in the char structure led to a limitation of pore development in the micropore ...
