Polarization shaping for unidirectional rotational motion of molecules.

Physical review letters

Karras G, Ndong M, Hertz E, Sugny D, Billard F, Lavorel B, Faucher O.
PMID: 25815926
Phys Rev Lett. 2015 Mar 13;114(10):103001. doi: 10.1103/PhysRevLett.114.103001. Epub 2015 Mar 10.

Control of the orientation of the angular momentum of linear molecules is demonstrated by means of laser polarization shaping. For this purpose, we combine two orthogonally polarized and partially time-overlapped femtosecond laser pulses so as to produce a spinning...

Generalized full-vector multi-mode matching analysis of whispering gallery microcavities.

Optics express

Du X, Vincent S, Faucher M, Picard MJ, Lu T.
PMID: 24921544
Opt Express. 2014 Jun 02;22(11):13507-14. doi: 10.1364/OE.22.013507.

We outline a full-vectorial three-dimensional multi-mode matching technique in a cylindrical coordinate system that addresses the mutual coupling among multiple modes co-propagating in a perturbed whispering gallery mode microcavity. In addition to its superior accuracy in respect to our...

Spin-Spin Coupling between Quadrupolar Nuclei in Solids: (11)B-(75)As Spin Pairs in Lewis Acid-Base Adducts.

The journal of physical chemistry. A

Faucher A, Terskikh VV, Wasylishen RE.
PMID: 26075575
J Phys Chem A. 2015 Jul 09;119(27):6949-60. doi: 10.1021/acs.jpca.5b04163. Epub 2015 Jun 29.

Solid-state (11)B NMR measurements of Lewis acid-base adducts of the form R3AsBR'3 (R = Me, Et, Ph; R' = H, Ph, C6F5) were carried out at several magnetic field strengths (e.g., B0 = 21.14, 11.75, and 7.05 T). The...

Numerical study of sensitivity enhancement in a photonic crystal microcavity biosensor due to optical forces.

Optics express

Heiniger AT, Miller BL, Fauchet PM.
PMID: 26406707
Opt Express. 2015 Sep 21;23(19):25072-83. doi: 10.1364/OE.23.025072.

Photonic crystal microcavity biosensors can detect single biomolecules, but reliance on diffusion from microfluidic flow for particle delivery limits the minimum detectable particle concentration. Here the particle equation of motion is solved to find the sensitivity enhancement due to...

Hippocampal Injections of Oligomeric Amyloid β-peptide (1-42) Induce Selective Working Memory Deficits and Long-lasting Alterations of ERK Signaling Pathway.

Frontiers in aging neuroscience

Faucher P, Mons N, Micheau J, Louis C, Beracochea DJ.
PMID: 26793098
Front Aging Neurosci. 2016 Jan 11;7:245. doi: 10.3389/fnagi.2015.00245. eCollection 2015.

Increasing evidence suggests that abnormal brain accumulation of soluble rather than aggregated amyloid-β1-42 oligomers (Aβo(1-42)) plays a causal role in Alzheimer's disease (AD). However, as yet, animal's models of AD based on oligomeric amyloid-β1-42 injections in the brain have...

Dynamical Stark Effect in the nu(2)/nu(4) Vibrational Polyad of SiH(4): Theory and Observation.

Journal of molecular spectroscopy

Dupont J, Déroussiaux A, Coquard M, Lavorel B, Faucher O, Loëte M, Jauslin HR.
PMID: 10637111
J Mol Spectrosc. 2000 Feb;199(2):252-258. doi: 10.1006/jmsp.1999.8013.

We report a theoretical and experimental investigation of the dynamical Stark effect in a tetrahedral molecule, silane (SiH(4)). We use a tetrahedral formalism and Floquet theory to calculate the absorption spectra for the molecule dressed by an intense nonresonant...

Ordering and self-organization in nanocrystalline silicon.

Nature

Grom GF, Lockwood DJ, McCaffrey JP, Labbe HJ, Fauchet PM, White B, Diener J, Kovalev D, Koch F, Tsybeskov L.
PMID: 11014187
Nature. 2000 Sep 21;407(6802):358-61. doi: 10.1038/35030062.

The spontaneous formation of organized nanocrystals in semiconductors has been observed during heteroepitaxial growth and chemical synthesis. The ability to fabricate size-controlled silicon nanocrystals encapsulated by insulating SiO2 would be of significant interest to the microelectronics industry. But reproducible...

Synthesis, Structure, and Spectroscopy of Rare Earth Hypophosphites. 1. Anhydrous and Monohydrated Lanthanide Hypophosphites.

Opt Express. 2005 May 16;13(10):3754-64. doi: 10.1364/opex.13.003754.

We propose a new design for an optical sensor based on porous silicon structures. We present an analysis based on a pole expansion, which allows for the easy identification of the parameters important for the operation of the sensor,...
