Pressure-Dependent Friction on Granular Slopes Close to Avalanche.

Physical review letters

Crassous J, Humeau A, Boury S, Casas J.
PMID: 28949714
Phys Rev Lett. 2017 Aug 04;119(5):058003. doi: 10.1103/PhysRevLett.119.058003. Epub 2017 Aug 03.

We investigate the sliding of objects on an inclined granular surface close to the avalanche threshold. Our experiments show that the stability is driven by the surface deformations. Heavy objects generate footprintlike deformations which stabilize the objects on the...

Dynamic Regulation of Auxin Response during Rice Development Revealed by Newly Established Hormone Biosensor Markers.

Frontiers in plant science

Yang J, Yuan Z, Meng Q, Huang G, Périn C, Bureau C, Meunier AC, Ingouff M, Bennett MJ, Liang W, Zhang D.
PMID: 28326089
Front Plant Sci. 2017 Mar 07;8:256. doi: 10.3389/fpls.2017.00256. eCollection 2017.

The hormone auxin is critical for many plant developmental processes. Unlike the model eudicot plant

Immunoprofiling of Rice Root Cortex Reveals Two Cortical Subdomains.

Frontiers in plant science

Henry S, Divol F, Bettembourg M, Bureau C, Guiderdoni E, Périn C, Diévart A.
PMID: 26779208
Front Plant Sci. 2016 Jan 07;6:1139. doi: 10.3389/fpls.2015.01139. eCollection 2015.

The formation and differentiation of aerenchyma, i.e., air-containing cavities that are critical for flooding tolerance, take place exclusively in the cortex. The understanding of development and differentiation of the cortex is thus an important issue; however, studies on this...

Mechanically Tunable Dielectric Resonator Metasurfaces at Visible Frequencies.

ACS nano

Gutruf P, Zou C, Withayachumnankul W, Bhaskaran M, Sriram S, Fumeaux C.
PMID: 26617198
ACS Nano. 2016 Jan 26;10(1):133-41. doi: 10.1021/acsnano.5b05954. Epub 2015 Dec 02.

Devices that manipulate light represent the future of information processing. Flat optics and structures with subwavelength periodic features (metasurfaces) provide compact and efficient solutions. The key bottleneck is efficiency, and replacing metallic resonators with dielectric resonators has been shown...

Terahertz near-field imaging of dielectric resonators.

Optics express

Lee WS, Kaltenecker K, Nirantar S, Withayachumnankul W, Walther M, Bhaskaran M, Fischer BM, Sriram S, Fumeaux C.
PMID: 28241587
Opt Express. 2017 Feb 20;25(4):3756-3764. doi: 10.1364/OE.25.003756.

As an alternative to metallic resonators, dielectric resonators can increase radiation efficiencies of metasurfaces at terahertz frequencies. Such subwavelength resonators made from low-loss dielectric materials operate on the basis of oscillating displacement currents. For full control of electromagnetic waves,...

Cryptic dioecy and leaky dioecy in endemic species of Dombeya (Sterculiaceae) on La Reunion.

American journal of botany

Humeau L, Pailler T, Thompson JD.
PMID: 10523284
Am J Bot. 1999 Oct;86(10):1437-47.

The high frequency of dioecy on oceanic islands such as Hawaii and New Zealand has attracted a great deal of attention from plant evolutionary biologists. One reason suggested for the high prevalence of dioecy on oceanic islands is that...

Synthesis, structure, and characterisation of a new phenolato-bridged manganese complex [Mn2(mL)2]2+: chemical and electrochemical access to a new mono-mu-oxo dimanganese core unit.

Chemistry (Weinheim an der Bergstrasse, Germany)

Hureau C, Sabater L, Anxolabéhère-Mallart E, Nierlich M, Charlot MF, Gonnet F, Rivière E, Blondin G.
PMID: 15079840
Chemistry. 2004 Apr 19;10(8):1998-2010. doi: 10.1002/chem.200305515.

The dinuclear phenolato-bridged complex [(mL)Mn(II)Mn(II)(mL)](ClO(4))(2) (1(ClO(4))(2)) has been obtained with the new [N(4)O] pentadentate ligand mL(-) (mLH=N,N'-bis-(2-pyridylmethyl)-N-(2-hydroxybenzyl)-N'-methyl-ethane-1,2-diamine) and has been characterised by X-ray crystallography. X- and Q-band EPR spectra were recorded and their variation with temperature was examined. All...

Quantitative and molecular epidemiology of bacterial blight of onion in seed production fields.

Phytopathology

Humeau L, Roumagnac P, Picard Y, Robène-Soustrade I, Chiroleu F, Gagnevin L, Pruvost O.
PMID: 18943667
Phytopathology. 2006 Dec;96(12):1345-54. doi: 10.1094/PHYTO-96-1345.

ABSTRACT Onion, a biennial plant species, is threatened by the emerging, seed-borne, and seed-transmitted Xanthomonas axonopodis pv. allii. Bacterial blight epidemics were monitored in seed production fields over two seasons. Temporal disease progress was different between the two seasons,...

Univocal demonstration of the electrochemically mediated binding of Pb2+ by a modified surface incorporating a TTF-based redox-switchable ligand.

Journal of the American Chemical Society

Lyskawa J, Le Derf F, Levillain E, Mazari M, Sallé M, Dubois L, Viel P, Bureau C, Palacin S.
PMID: 15453714
J Am Chem Soc. 2004 Oct 06;126(39):12194-5. doi: 10.1021/ja047411q.

A tetrathiafulvalene-based redox-switchable ligand with unprecedented electrochemical recognition properties for a metallic cation is described and is chemically immobilized onto a solid surface. The recognition properties for Pb2+ are maintained at the solid-liquid interface. Evidence of the modulation of...

Molecule-to-metal bonds: electrografting polymers on conducting surfaces.

Chemphyschem : a European journal of chemical physics and physical chemistry

PMID: 15535544
Chemphyschem. 2004 Oct 18;5(10):1468-81. doi: 10.1002/cphc.200301202.

Electrografting is a powerful and versatile technique for modifying and decorating conducting surfaces with organic matter. Mainly based on the electro-induced polymerization of dissolved electro-active monomers on metallic or semiconducting surfaces, it finds applications in various fields including biocompatibility,...
