Influence of solid solution formation on polarity: molecular modeling investigation of the system 4-chloro-4'-nitrostilbene/4,4'-dinitrostilbene.

The journal of physical chemistry. B

Gervais C, Wüst T, Hulliger J.
PMID: 16852556
J Phys Chem B. 2005 Jun 30;109(25):12582-9. doi: 10.1021/jp0505835.

Growth-induced polarity formation in solid solutions composed of dipolar 4-chloro-4'-nitrostilbene molecules and nonpolar 4,4'-dinitrostilbene molecules was investigated by means of two molecular modeling procedures. Calculation of the mixing energy in the bulk structures predicted solid solution formation within the...

Kinematically complete study of dissociative ionization of by ion impact.

Physical review letters

Laurent G, Fernández J, Legendre S, Tarisien M, Adoui L, Cassimi A, Fléchard X, Frémont F, Gervais B, Giglio E, Grandin JP, Martín F.
PMID: 16712294
Phys Rev Lett. 2006 May 05;96(17):173201. doi: 10.1103/PhysRevLett.96.173201. Epub 2006 May 01.

We present a kinematically complete study of dissociative ionization of D(2) by 13.6 MeV/u S(15+) ions. The experiment allows us to unravel the competing mechanisms, namely, direct single ionization, autoionization of doubly excited states, ionization excitation, and double ionization,...

Structure of a surfactant-templated silicate framework in the absence of 3d crystallinity.

Journal of the American Chemical Society

Hedin N, Graf R, Christiansen SC, Gervais C, Hayward RC, Eckert J, Chmelka BF.
PMID: 15281835
J Am Chem Soc. 2004 Aug 04;126(30):9425-32. doi: 10.1021/ja040030s.

The structure of a novel molecularly ordered two-dimensional (2D) silicate framework in a surfactant-templated mesophase has been established by using a combination of solid-state nuclear magnetic resonance (NMR) spectroscopy, X-ray diffraction, and quantum chemical and empirical force-field modeling. These...

Determination of the antisymmetric part of the chemical shift anisotropy tensor via spin relaxation in nuclear magnetic resonance.

The Journal of chemical physics

Paquin R, Pelupessy P, Duma L, Gervais C, Bodenhausen G.
PMID: 20649336
J Chem Phys. 2010 Jul 21;133(3):034506. doi: 10.1063/1.3445777.

Relaxation processes induced by the antisymmetric part of the chemical shift anisotropy tensor (henceforth called anti-CSA) are usually neglected in NMR relaxation studies. It is shown here that anti-CSA components contribute to longitudinal relaxation rates of the indole (15)N...

Influence of Water Potential on gamma-Decalactone Production by the Yeast Sporidiobolus salmonicolor.

Applied and environmental microbiology

Gervais P, Battut G.
PMID: 16348056
Appl Environ Microbiol. 1989 Nov;55(11):2939-43. doi: 10.1128/aem.55.11.2939-2943.1989.

The influence of water potential on gamma-decalactone production by the yeast Sporidiobolus salmonicolor cultivated in a liquid medium was evaluated by gas-chromatographic analysis. Modifications in water potential led to a number of variations in the aroma production. Maximum extracellular...

An accurate model potential for alkali neon systems.

The Journal of chemical physics

Zanuttini D, Jacquet E, Giglio E, Douady J, Gervais B.
PMID: 19968334
J Chem Phys. 2009 Dec 07;131(21):214104. doi: 10.1063/1.3269801.

We present a detailed investigation of the ground and lowest excited states of M-Ne dimers, for M=Li, Na, and K. We show that the potential energy curves of these Van der Waals dimers can be obtained accurately by considering...

Structure and photoabsorption properties of cationic alkali dimers solvated in neon clusters.

The Journal of chemical physics

Zanuttini D, Douady J, Jacquet E, Giglio E, Gervais B.
PMID: 21054047
J Chem Phys. 2010 Nov 07;133(17):174503. doi: 10.1063/1.3490251.

We present a theoretical investigation of the structure and optical absorption of M(2)(+) alkali dimers (M=Li,Na,K) solvated in Ne(n) clusters for n=1 to a few tens Ne atoms. For all these alkali, the lowest-energy isomers are obtained by aggregation...

Evidence for skyrmion crystallization from NMR relaxation experiments.

Physical review letters

Gervais G, Stormer HL, Tsui DC, Kuhns PL, Moulton WG, Reyes AP, Pfeiffer LN, Baldwin KW, West KW.
PMID: 16090197
Phys Rev Lett. 2005 May 20;94(19):196803. doi: 10.1103/PhysRevLett.94.196803. Epub 2005 May 18.

A resistively detected NMR technique was used to probe the two-dimensional electron gas in a GaAs/AlGaAs quantum well. The spin-lattice relaxation rate (1/T(1)) was extracted at near complete filling of the first Landau level by electrons. The nuclear spin...

A-site ordering in colossal magnetoresistance manganite La(1-x)Sr(x)MnO3? Molecular dynamics simulations and quantum mechanics calculations.

The Journal of chemical physics

Jang YH, Gervais F, Lansac Y.
PMID: 19739857
J Chem Phys. 2009 Sep 07;131(9):094503. doi: 10.1063/1.3190533.

Recent experiments have called into question the assumption of a random A-site distribution in mixed-valence colossal magnetoresistance (CMR) manganites. We explored the possibility of an A-site (La(3+)/Sr(2+)) ordering in a CMR manganite La(3/4)Sr(1/4)MnO(3) using molecular dynamics (MD) simulations with...
