Abstract
Adsorption at the interface between liquid n-heptane and a graphite substra te has been studied by incoherent elastic/quasielastic neutron scattering a nd coherent neutron diffraction, A solid monolayer of n-heptane persists ab ove the bulk melting point (183 K) and melts at 206 K, which is in contrast to the fact that the monolayer adsorbed at submonolayer coverages melts at 151 K. The crystalline structure is significantly different between those two monolayers. (C) 1999 Elsevier Science Ltd. All rights reserved.
