Gold nanoparticles confined in lamellar mesophases

W. Abidi, B. Pansu, R. Krishnaswamy, P. Beaunier, H. Remita, M. Impéror-Clerc

A lamellar surfactant mesophase is used as a soft confinement medium for gold nanoparticles that are directly synthesized inside the lamellar mesophase by the radiolytic reduction of a gold salt incorporated into the water medium. By increasing the water layer thickness of the mesophase, spherical…

CO2 valorization using epoxides under mild conditions

Chetna Mohabeer, Lionel Estel, Laurent Bischoff, Vincent Levacher, Marie-Pierre Denieul, Alain Ledoux, Salim Derrouiche

Carbon dioxide is the major greenhouse gas suspected to produce the climatic change. In order to reduce the emissions of CO 2 , several ways have been studied like capture process, geological storage and valorization. Recently one of the most important studies is concentrated on chemical…

TiO2-Copper on smart textiles in a prototype plug flow reactor for enhanced photocatalytic removal of contaminants in fruit storage environments

Sarra Karoui, Amine Aymen Assadi, Nabisab Mujawar Mubarak, Abdeltif Amrane

The photocatalysis technique was chosen for its non-toxicity and high efficiency in combating indoor air pollution caused by volatile organic compounds (VOCs) and microorganisms. This paper investigates and discusses the simultaneous gas-phase removal of Ethyl acetate (EA) and Escherichia coli (E.…

True Circular Dichroism in Optically Active Achiral Metasurfaces and Its Relation to Chiral Near-Fields

Mathieu Nicolas, Per Magnus Walmsness, Jayeeta Amboli, Lu Zhang, Guillaume Demesy, Nicolas Bonod, Souhir Boujday, Morten Kildemo, Bruno Gallas

Optically active achiral metasurfaces offer a promising way to detect chiral molecules based on chiroptic methods. The combination of plasmonic enhanced circular dichroism and reversible optical activity would boost the sensitivity and provide enantiomerselective surfaces while using a single…

Inhalation of uranium nanoparticles: respiratory tract deposition and translocation to secondary target organs in rats.

Fabrice Petitot, Philippe Lestaevel, Elie Tourlonias, Charline Mazzucco, Sébastien Jacquinot, Bernadette Dhieux, Olivia Delissen, Benjamin B. Tournier, Charline Gendarmes, Patricia Beaunier, Isabelle Dublineau

Uranium nanoparticles (<100 nm) can be released into the atmosphere during industrial stages of the nuclear fuel cycle and during remediation and decommissioning of nuclear facilities. Explosions and fires in nuclear reactors and the use of ammunition containing depleted uranium can also produce…

Evolution Mechanisms of T91 Steel in Subcritical Conditions and Role of an Internal Oxidation Zone

Seifallah Fetni, David Montero, Chokri Boubahri, Dalil Brouri, Jalel Briki

Corrosion of a T91 steel tube, used in subcritical conditions in an oil power plant for 157,000 h, was characterized mainly through SEM, TEM, EDX and DRX analyses. Severe oxidation and carburization took place in both the outer (boiler) and inner (steam) wall sides. The nature and morphology of the…

The Acidity of Zeolites: Concepts, Measurements and Relation to Catalysis: A Review on Experimental and Theoretical Methods for the Study of Zeolite Acidity

E.G. Derouane, Jacques C. Vedrine, Ramos R. Pinto, P.M. Borges, L. Costa, M. A. N. D. A. Lemos, F. Lemos, Ramôa Ribeiro

In this article, we considered all aspects of acidity (nature of acid sites, strength, density, etc.) in solid catalysts and in zeolites in particular. After reminding the definition of acidity in liquid and solid acids, we emphasized acidity characterization by the most used physical techniques,…

Remarkable effect of postsynthesis preparation procedures on catalytic properties of Ni-loaded BEA zeolites in hydrodechlorination of 1,2-dichloroethane

A. Śrębowata, R. Baran, D. Łomot, D. Lisovytskiy, T. Onfroy, S. Dzwigaj

Ni2.0SiBEA and Ni2.0HAlBEA zeolites were prepared by two different procedures: (i) a two-step postsynthesis method that consist of (1) creation of vacant T-atom sites by dealumination of HAlBEA (Si/Al = 17) with nitric acid and then (2) impregnation of as resulting SiBEA (Si/Al > 1300) with…

Aerobic Selective Oxidation of Alcohols and Alkanes over Hydroxyapatite-Based Catalysts

Guylène Costentin, Franck Launay

Selective oxidation catalysis is of prime importance for the production of many key intermediates. The control of selectivity in the presence of gaseous oxygen is quite challenging and requires the development of efficient catalysts. Thanks to their large composition range, resulting from the…

Nouvelles biocathodes graphite/nitrure de carbone amorphe/laccase pour la réduction de l'oxygène par transfert électronique direct

Achraft Blout, Alain Pailleret, Hubert Perrot, Claude Jolivalt

Les enzymes constituent une alternative intéressante aux catalyseurs métalliques car elles possèdent une meilleure sélectivité et des performances catalytiques souvent plus élevées. Elles peuvent être utilisées dans différents types de dispositifs électrochimiques comme les piles à combustible1.…
