Real-time monitoring of the uniform corrosion rate of aluminum using picosecond acoustic method

Cyrine Lamloum, Oumaïma Gharbi, Laurent Belliard, Vincent Vivier, Kieu Ngo

This paper introduces a novel operando measurement technique to monitor the degradation rate of aluminum (a thin layer of Al deposited on a sapphire substrate), first in a commercial aluminum etching solution, and then in a sodium chloride solution using a pumpprobe spectroscopy technique. By…

Controlled Formation of Native Defects in Ultrapure ZnO for the Assignment of Green Emissions to Oxygen Vacancies

Fredeŕic Averseng, Miao Zhang, Frederic Averseng, Jean-Marc Krafft, Patrizia Borghetti, Guylène Costentin, Slavica Stankic

Ultrapure ZnO nanopowders were synthesized via vapor-phase based methods under oxygen deficient conditions. The type and relative proportions of intrinsic point defects were studied by photoluminescence (PL) and EPR spectroscopies performed under strictly controlled conditions. Besides coupled PL…

Surface-induced assembly of sophorolipids

Jessie Peyre, Ahmed Hamraoui, Marco Faustini, Vincent Humblot, Niki Baccile

The surface self-assembly properties of acidic sophorolipids, a bolaform microbial glycolipids with pH-responsive properties in solution, were studied based on the chemical nature of the support and pH of the solution. Sophorolipids generally form micelles in water but formation of morphologies…

Photocatalyseurs nanocomposites UCNP@SiO2@ZnO, activés par rayonnement proche infrarouge, pour la dépollution des eaux usées, Nanocomposites photocatalysts UCNP@SiO2@ZnO, active under near-infrared light, for wastewater treatment

David Hu

Les photocatalyseurs tels que l’oxyde de zinc (ZnO) peuvent minéraliser les polluants organiques toxiques et persistants dans les eaux usées. Ils ne sont cependant pas efficients dans les eaux très contaminées, suite à la nécessité d’une activation par une lumière UV qui n’y pénètre que faiblement.…, Photocatalysts such as zinc oxide (ZnO) can mineralize toxic and persistent organic pollutants present in wastewaters. Unfortunately, these photocatalysts loose part of their effectiveness because they need to be activated by UV light, which has a limited penetration depth in highly contaminated…

Insights into bacteriophage T5 structure from analysis of its morphogenesis genes and protein components.

Yvan Zivanovic, Fabrice Confalonieri, Luc Ponchon, Rudi Lurz, Mohamed Chami, Ali Flayhan, Madalena Renouard, Alexis Huet, Paulette Decottignies, Alan R Davidson, Cécile Breyton, Pascale Boulanger

Bacteriophage T5 represents a large family of lytic Siphoviridae infecting Gram-negative bacteria. The low-resolution structure of T5 showed the T=13 geometry of the capsid and the unusual trimeric organization of the tail tube, and the assembly pathway of the capsid was established. Although major…

Biomass-mediated ZSM-5 zeolite synthesis: when self-assembly allows to cross the Si / Al lower limit

Marcelo Maciel Pereira, Elisa Gomes, Alessandra Vieira Silva, Ana Belen Pinar, Marc-Georg Willinger, Sangaraju Shanmugam, Céline Chizallet, Guillaume Laugel, Pit Losch, Benoit Louis

A family of Al-rich ZSM-5 zeolites with Si / Al = 8 ± 0.5 was prepared according to a biomass-mediated supramolecular approach. A combination of advanced characterisation techniques and periodic density functional theory (DFT) calculations unraveled the purity and stability of unexpected Al…

Calibrated Co3O4 nanoparticles patterned in SBA-15 3 silicas: Accessibility and activity for CO oxidation

Irène Lopes, Anne Davidson, Cyril Thomas

The catalytic performances in CO oxidation of Co3 O4 nanoparticles patterned in the porosity of SBA-15 silicas are investigated. 10 Accessibility limitations of the reactants to the catalytic sites are clearly revealed,when the Co3O4 nanoparticles are embedded in the 11 SBA-15 pores.Despite these…

Catalytic conversion of trichloroethylene on nickel containing beta zeolites into value added products

A. Śrębowata, R. Baran, D. Lisovytskiy, I.I. Kamińska, S. Dzwigaj

Nickel containing BEA zeolites, NiSiBEA and NiHAlBEA, with 2 wt% of Ni were prepared by a two-step postsynthesis method and conventional wet impregnation. The calcination of NiSiBEA and NiHAlBEA at 773 K for 3 h in air led to the formation of C-NiSiBEA and C-NiHAlBEA. After reduction at 873 K for 3…

Martinez, F Rigal

Context. The nearby and young M star AU Mic is surrounded by a debris disk in which we previously identified a series of large-scale arch-like structures that have never been seen before in any other debris disk and that move outward at high velocities.Aims. We initiated a monitoring program with…
