The electrons found in Dirac materials are notorious for being difficult to manipulate due to the Klein phenomenon and absence of backscattering. Here we investigate how spatial modulations of the Fermi velocity in two-dimensional Dirac materials can give rise to locali...

This paper describes a transportable distance measurement system based on synthetic wavelength interferometry using two frequency-doubled Nd:YAG lasers. To eliminate polarization crosstalk issue, a different system has been set up from those usually described in the lit...

International audience; The design and characterization of amorphous alternating copolymers endowed with a satisfactory thermal stability are reported. These alternating poly(CTFE- alt -CEVE) copolymers are synthesized by radical copolymerization of chlorotrifl uoroethy...

This work was supported by the grants by the Region Aquitaine (to E.M.B) and PEPS (Initial Support for Exploratory Projects to E.M.B) and National Agency for Research (Grant ANR-14-CE19-0006-01 to E.M.B). Plasmodesmata are remarkable cellular machines responsible for th...

International audience; Trophic conditions and water temperature strongly influence bivalve physiological processes and metabolism. In black-lip pearl oyster Pinctada margaritifera, these parameters have been shown to affect shell biomineralization. The present study in...

In a previous paper [1], the synthesis of various polystyrene– poly[NIPAM] core–shell latexes bearing cationic amidino and/or amino charges has been described. Several colloidal properties of these cationic latexes have been charac-terized such as: particle size, surfac...

Abstract The apicomplexan Toxoplasma gondii , an obligate intracellular parasite, can infect humans and a wide range of vertebrates. Following oral infection, the parasite invades tissues by crossing non-permissive biological barriers such as the placenta or the blood–b...

The synthesis, structure, and reactivity of a new complex of U(IV) with the tridentate Schiff base ligand Menaphtquinolen are reported. The reduction of the bis-ligand complexes [UX2(Menaphtquinolen) 2] (X = Cl, (1-Cl); I (1-I)) with potassium metal affords the U(IV) co...

International audience; This paper deals with construction and convergence analysis of a finite volume scheme for compressible/incompressible (gas-water) flows in porous media. The convergence properties of finite volume schemes or finite element scheme are only known f...

Through coupled thermal and orbital calculations including a full description of tidal dissipation, heat transfer and the H 2O–NH3 phase diagram, we propose a model for the internal structure and composition of Titan testable with Cassini–Huygens measurements. The high ...
