      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 ...

      Studies of steam-activated viscose rayon chars 

      Tomlinson, J. B.; Theocharis, Charis R. (1992)
      Standard techniques, such as nitrogen adsorption, mercury porosimetry, and X-ray photoelectron spectroscopy, have been used to characterise steam-activated viscose rayon-derived chars pretreated with aqueous solutions of ...
