All in one: holographic microscopy unveils bacterial transport from single cells to population
Lucie Klopffer, S. Becker, Laurence Mathieu +1
Prior to pioneer surface adhesion, bacteria have to navigate in flows, often in confined environments. While much is known about their individual swimming dynamics, our understandi…
An Abelian Higgs model for disclinations in nematics
A. de Pádua Santos, F. Moraes, F. A. N. Santos +1
Topological defects in elastic media may be described by a geometric field akin to three-dimensional gravity. From this point of view, disclinations are line defects of zero width…
Interaction of ammonium with birnessite: Evidence of a chemical and structural transformation in alkaline aqueous medium
Hella Boumaiza, Romain Coustel, Christelle Despas +2
The ammonium cation interaction with Na-birnessite in aqueous alkaline medium was studied. Solution and solid analysis give evidence that birnessite is not only acting as a cationi…
Conditions for the formation of pure birnessite during the oxidation of Mn(II) cations in aqueous alkaline medium
Hella Boumaiza, Romain Coustel, Ghouti Medjahdi +2
Birnessite was synthetized through redox reaction by mixing MnO4-, Mn2+ and OH- solutions. The Mn(VII): Mn(II) ratio of 0.33 was chosen and three methods were used consisting in a…
Covalent Functionalization of HiPco Single-Walled Carbon Nanotubes: Differences in the Oxidizing Action of H2SO4 and HNO3 during a Soft Oxidation Process
Xavier Devaux, Brigitte Vigolo, Edward Mcrae +7
The results of a study on the evolution of HiPco single-walled carbon nanotubes during the oxidizing action of H2SO4 and HNO3 are presented. The process conditions used have been c…
Preliminary Synthesis of Carbon Nitride Thin Films by N/CH Microwave Plasma Assisted Chemical Vapour Deposition: Characterisation of the Discharge and the Obtained Films
Paul Kouakou, Valerie Brien, Badreddine Assouar +4
The present work deals with the synthesis of crystalline carbon nitride thin films by microwave plasma assisted chemical vapour deposition in N/CH gas mixture. The discharg…
