Molecular dynamics of a short range ordered smectic phase nanoconfined into porous silicon
Régis Guégan, Denis Morineau, Ronan Lefort +5
4-n-octyl-4-cyanobiphenyl (8CB) has been recently shown to display an unusual sequence of phases when confined into porous silicon (PSi). The gradual increase of oriented short-ran…
Exploring conformational energy landscape of glassy disaccharides by CPMAS 13C NMR and DFT/GIAO simulations. II. Enhanced molecular flexibility in amorphous trehalose
Ronan Lefort, Patrice Bordat, Attilio Cesaro +1
This paper deals with the comparative use of the chemical shift surfaces to simulate experimental 13C CPMAS data on amorphous solid state disaccharides, paying particular attention…
Exploring conformational energy landscape of glassy disaccharides by CPMAS 13C NMR and DFT/GIAO simulations. I. Methodological aspects
Ronan Lefort, Patrice Bordat, Attilio Cesaro +1
The aim of this article is to assess the ability of chemical shift surfaces to provide structural information on conformational distributions of disaccharides in glassy solid state…
Mutarotational Kinetics and Glass Transition of Lactose
Ronan Lefort, Vincent Caron, Jean-François Willart +1
We report for the first time real time in situ and quantitative measurements of the mutarotation reaction of lactose in the solid state. The experiments have been performed by 13C…
Structure and relaxation processes of an anisotropic molecular fluid confined into 1D nanochannels
Ronan Lefort, Denis Morineau, Régis Guégan +3
Structural order parameters of a smectic liquid crystal confined into the columnar form of porous silicon are studied using neutron scattering and optical spectroscopic techniques.…
Dynamics of 8CB confined into porous silicon probed by incoherent neutron backscattering experiments
Régis Guégan, Ronan Lefort, Wilfried Béziel +3
Confinement in the nanochannels of porous silicon strongly affects the phase behavior of the archetype liquid-crystal 4-n-octyl-4-cyanobiphenyl (8CB). A very striking phenom- enon…
