Calorimetry and neutron di†raction have been used to identify and characterise the formation of a solid monolayer of pentane adsorbed on graphite and coexisting with liquid pentane. The observed behaviour is quite di†erent from other alkanes in that the monolayer does not melt above the melting temperature of the pure pentane but at a...

The combination of sensitive calorimetry, incoherent elastic neutron scattering and neutron di†raction has been used to demonstrate the formation of solid layers containing both octane and nonane adsorbed onto graphite from the binary alkane mixture. This combination of methods allow us to characterise the adsorbed layer in some detail...

The behaviour of binary mixtures of octane and nonane adsorbed on graphite has been investigated with a combination of adiabatic calorimetry and neutron di†raction. In contrast to the eutectic behaviour of monolayers of these materials at higher coverages, this combination of alkanes is found to form mixed crystals on the surface over an...

Neutron and X-ray diffraction have been used to structurally characterise the crystalline monolayer structures of hexane, octane, decane, dodecane and tetradecane adsorbed on graphite at sub-monolayer coverages and when coexisting with liquid alkane. The structures of all the molecules investigated at both coverages and low temperatures are...

A combination of neutron and X-ray diffraction has been used to structurally characterise the crystalline monolayer structures of all the alkanes with odd number of carbon atoms in their alkyl chains from pentane to pentadecane adsorbed on graphite. The structures of all the molecules investigated at submonolayer coverages are isomorphous with...
