Adsorption Science & Technology, 1992 The adsorption and desorption isotherms of n-hexane on powdered alumina and silica have been studied at 25°C over a wide range of relative pressures. Two t-curves for pore structure analysis are proposed, one for alumina (C = 12) and the second for silica (3 ≤ C ≤ 9).

Multilayer Graphene Synthesized by CVD Using Liquid Hexane as the Carbon Precursor [PDF]
World Journal of Condensed Matter Physics, 1(2011)157-160, 2011 We produce multilayer graphene by the Chemical Vapor Deposition (CVD) method at atmospheric pressure and 1000 {\deg}C, using flexible copper substrates as catalyst and liquid hexane as the source of carbon. We designed an optical device to measure the transmittance of the carbon films; with this information we calculate that the approximate number of ...
