Contact forces in a granular packing.

Chaos (Woodbury, N.Y.)

Radjai F, Roux S, Moreau JJ.
PMID: 12779850
Chaos. 1999 Sep;9(3):544-550. doi: 10.1063/1.166428.

We present the results of a systematic numerical investigation of force distributions in granular packings. We find that all the main features of force transmission previously established for two-dimensional systems of hard particles hold in three-dimensional systems and for...

Respiratory tract epithelium in primary culture: Effects of ciliotoxic compounds.

Toxicology in vitro : an international journal published in association with BIBRA

Romet S, Dubreuil A, Baeza A, Moreau A, Schoevaert D, Marano F.
PMID: 20702203
Toxicol In Vitro. 1990;4(4):399-402. doi: 10.1016/0887-2333(90)90089-c.

Acrolein ciliotoxicity was studied on primary cultures from rabbit tracheal epithelium. The inhibition of ciliary beat was chosen as a criterion for ciliotoxicity. The measurement of ciliary beat was accomplished using an original image analysis process.

Large negative lateral shifts due to negative refraction.

Optics letters

Benedicto J, Pollès R, Moreau A, Centeno E.
PMID: 21725472
Opt Lett. 2011 Jul 01;36(13):2539-41. doi: 10.1364/OL.36.002539.

When a thin structure in which negative refraction occurs (a metallo-dielectric structure or a photonic crystal) is illuminated by a beam, the reflected and transmitted beam can undergo a large negative lateral shift. This phenomenon can be seen as...

Lattice dynamics of oligo(phenylenethienylene)s: a far-infrared and inelastic neutron scattering study.

The journal of physical chemistry. B

Hermet P, Lois-Sierra S, Bantignies JL, Rols S, Sauvajol JL, Serein-Spirau F, Lère-Porte JP, Moreau JJ.
PMID: 19254013
J Phys Chem B. 2009 Apr 02;113(13):4197-202. doi: 10.1021/jp808652c.

New promising oligo(phenylenethienylene)s have been synthesized to realize suitable materials for improving electronic transport properties, particularly in organic field effect transistors (OFETs). Far-infrared and incoherent neutron scattering measurements have been performed to assign their phonon modes. The assignment of...

Second-harmonic generation and crystal structure of the diamond-like semiconductors Li(2)CdGeS(4) and Li(2)CdSnS(4).

Inorganic chemistry

Lekse JW, Moreau MA, McNerny KL, Yeon J, Halasyamani PS, Aitken JA.
PMID: 19621873
Inorg Chem. 2009 Aug 17;48(16):7516-8. doi: 10.1021/ic9010339.

The semiconductors Li(2)CdGeS(4) and Li(2)CdSnS(4), which are of interest for their nonlinear optical properties, were synthesized using high-temperature solid-state and polychalcogenide flux syntheses. Both compounds were found to crystallize in Pmn2(1), with R1 (for all data) = 1.93% and...

Electroactive nanorods and nanorings designed by supramolecular association of pi-conjugated oligomers.

Chemistry (Weinheim an der Bergstrasse, Germany)

Dautel OJ, Robitzer M, Flores JC, Tondelier D, Serein-Spirau F, Lère-Porte JP, Guérin D, Lenfant S, Tillard M, Vuillaume D, Moreau JJ.
PMID: 18366041
Chemistry. 2008;14(14):4201-13. doi: 10.1002/chem.200701638.

In investigations into the design and isolation of semiconducting nano-objects, the synthesis of a new bisureido pi-conjugated organogelator has been achieved. This oligo(phenylenethienylene) derivative was found to be capable of forming one-dimensional supramolecular assemblies, leading to the gelation of...

Metal-free Brønsted acid catalyzed formal [3 + 3] annulation. straightforward synthesis of dihydro-2H-chromenones, pyranones, and tetrahydroquinolinones.

The Journal of organic chemistry

Moreau J, Hubert C, Batany J, Toupet L, Roisnel T, Hurvois JP, Renaud JL.
PMID: 19950880
J Org Chem. 2009 Dec 04;74(23):8963-73. doi: 10.1021/jo901238y.

Brønsted acids catalyze the addition of enolizable beta-diketones, beta-ketoesters, and vinylogous amides to alpha,beta-unsaturated aldehydes to lead to substituted chromenones, pyranones, and tetrahydroquinolinones in good yields under mild reaction conditions via a formal [3 + 3] cycloaddition.

Convenient route to water-sensitive sol-gel precursors using click chemistry.

Chemical communications (Cambridge, England)

Moitra N, Moreau JJ, Cattoën X, Wong Chi Man M.
PMID: 20936216
Chem Commun (Camb). 2010 Nov 28;46(44):8416-8. doi: 10.1039/c0cc03417g. Epub 2010 Oct 08.

The CuAAC-'click' reaction under anhydrous conditions is reported as a new tool for the preparation of moisture-sensitive triethoxysilyl compounds that are obtained in 5 minutes in excellent yield with simple purification.

Light transmission by subwavelength square coaxial aperture arrays in metallic films.

Optics express

Moreau A, Granet G, Baida F, Van Labeke D.
PMID: 19465978
Opt Express. 2003 May 19;11(10):1131-6. doi: 10.1364/oe.11.001131.

Using the Fourier modal method, we study the enhanced transmission exhibited by arrays of square coaxial apertures in a metallic film. The calculated transmission spectrum is in good agreement with FDTD calculations. We show that the enhanced transmission can...

Legislating Change? Responses to Criminalizing Female Genital Cutting in Senegal.

Law & society review

Law Soc Rev. 2013 Dec 01;47(4):803-835. doi: 10.1111/lasr.12044.

Although the international community has recently promoted legislation as an important reform strategy for ending female genital cutting (FGC), there exist divergent views on its potential effects. Supporters argue that legal prohibition of FGC has a general deterrent effect,...
