Journal ArticleDOI
Signatures of the hydrogen bonding in the infrared bands of water.
TL;DR: The substructures of the two infrared bands are analyzed in terms of different levels of connectivity of the water molecules, along the statements of the percolation model and good agreement is shown as for the temperature evolution of liquid water.
Journal ArticleDOI
Transition alumina phases induced by heat treatment of boehmite: An X-ray diffraction and infrared spectroscopy study
A. Boumaza,L. Favaro,Jean Lédion,Gaël Sattonnay,J.-B. Brubach,P. Berthet,A. M. Huntz,Pascale Roy,Robert Tétot +8 more
TL;DR: In this article, the gamma, delta, theta and alpha-Al{sub 2}O{sub 3} phases, prepared by dehydration of aluminium oxihydroxide AlOOH (boehmite), were measured by XRD and IR spectroscopy on all samples.
Journal ArticleDOI
Dependence of Water Dynamics upon Confinement Size
J.-B. Brubach,A. Mermet,A. Filabozzi,A. Gerschel,Didier Lairez,Marie Pierre Krafft,Pascale Roy +6 more
TL;DR: In this paper, water confined in nonionic fluorocarbon reverse micelles was investigated through mid-infrared spectroscopy (OH stretching and bending modes), in combination with quasielastic light scattering data.
Journal ArticleDOI
Polymer inclusion membranes: The concept of fixed sites membrane revised
Clàudia Fontàs,Rafik Tayeb,Mahmoud Dhahbi,Emmanuelle Gaudichet,Francette Thominette,Pascale Roy,Karine Steenkeste,Marie-Pierre Fontaine-Aupart,Sophie Tingry,E. Tronel-Peyroz,Patrick Seta +10 more
TL;DR: In this article, the mechanism of facilitated transport of metal ions across polymer inclusion membranes (PIMs) is revised on the basis of transport flux measurements and of new data brought by techniques sensitive to local inter-molecular interactions and molecular diffusion.
Journal ArticleDOI
Water in Carbon Nanotubes: The Peculiar Hydrogen Bond Network Revealed by Infrared Spectroscopy
Simona Dalla Bernardina,Erwan Paineau,J.-B. Brubach,Patrick Judeinstein,Stéphan Rouzière,Pascale Launois,Pascale Roy +6 more
TL;DR: The first infrared study of water uptake at controlled vapor pressure in single walled carbon nanotubes with diameters ranging from 0.7 to 2.1 nm is reported, revealing a predominant contribution of loose H bonds even for fully hydrated states, irrespective of the nanotube size.
