      Adsorption of nitrogen and water vapour by activated Kevlar® chars 

      Freeman, J. J.; Tomlinson, J. B.; Sing, K. S. W.; Theocharis, Charis R. (1993)
      Fibrous activated carbons were prepared from Kevlar® (i.e. poly (p-phenylene terephthalamide), in the form of a commercially available woven textile. The cloth was carbonised in nitrogen and activated in either steam or ...

      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 ...

      The adsorption of water vapour by microporous solids 

      Carrott, P. J. M.; Kenny, M. B.; Roberts, R. A.; Sing, K. S. W.; Theocharis, Charis R. (1991)
      The adsorption of water vapour has been studied with a range of microporous carbons, zeolites and aluminophosphates in order to elucidate the relative influence of surface chemistry, pore size and pore shape upon the form ...

      The adsorption of water vapour by VPI-5, a large pore molecular sieve 

      Kenny, M. B.; Sing, K. S. W.; Theocharis, Charis R. (1991)
      The framework of VPI-5, the first molecular sieve having uniform pores larger than 1 nm diameter, is modified during removal of the zeolitic water

      Adsorptive properties and stability of VPI-5, a large-pore molecular sieve 

      Kenny, M. B.; Sing, K. S. W.; Theocharis, Charis R. (1992)
      The unusual adsorptive properties and the reported instability of VPI-5 have been investigated in some detail. The VPI-5 framework was found to undergo an irreversible but incomplete phase transformation to AlPO4-8 during ...

      Adsorptive Properties of Microporous Zro2 Gels 

      Ragai, J.; Selim, S.; Sing, K. S. W.; Theocharis, Charis R. (1993)
      Nitrogen adsorption studies were carried out on zirconia gels prepared through the agency of ammonium carbonate to zirconyl chloride solutions. The effect of heat treatment and cation uptake on the textural characteristics ...

      Characterization of microporous zirconia gels 

      Ragai, J.; Selim, S.; Sing, K. S. W.; Theocharis, Charis R. (1994)
      Microporous zirconia gels were prepared from zirconyl chloride by the reaction in aqueous solutions with either ammonium carbonate or bircarbonate. Under conditions of low pH the ammonium bicarbonate precipitated gels ...

      Incorporation of zinc in an aluminophosphate microporous phase 

      Bond, G. C.; Gelsthorpe, M. R.; Sing, K. S. W.; Theocharis, Charis R. (1985)
      A new molecular sieve with formula Zn0.06Al 0.96PO4 has been prepared, which has a structure similar to that of the aluminophosphate ALPO-5

      Rates of activation and scanning electron microscopy of polyarylamide-derived chars 

      Tomlinson, J. B.; Freeman, J. J.; Sing, K. S. W.; Theocharis, Charis R. (1995)
      Fibrous activated carbons were prepared from Kevlar® (poly (p-phenylene terephthalamide)) and Nomex® (poly (m-phenylene isophthalamide)) by carbonisation in nitrogen and subsequent activation in steam of carbon dioxide to ...

      Sorption of water vapour by partially decomposed calcium hydroxide 

      Sing, K. S. W.; Theocharis, Charis R.; Yeates, D. (1991)
      Abstract The surface chemistry of commercial grade calcium hydroxide was studied by sorption methods, thermal analysis and spectroscopy. Part of this investigation was the study of the sorption of water vapour by the ...
