In Situ Solid–Gas Reactivity of Nanoscaled Metal Borides from Molten Salt Synthesis

Guillaume Gouget, Damien P. Debecker, Ara Kim, Giorgia Olivieri, Jean-Jacques Gallet, Fabrice Bournel, Cyril Thomas, Ovidiu Ersen, Simona Moldovan, Clément Sanchez, Sophie Carenco, David Portehault

Metal borides have mostly been studied as bulk materials. The nanoscale provides new opportunities to investigate the properties of these materials, e.g., nanoscale hardening and surface reactivity. Metal borides are often considered stable solids because of their covalent character, but little is…

Aqueous nickel(II) hydroxycarbonate instead of nickel(0) colloids as precursors of stable Ni-silica based catalysts for the dry reforming of methane

Oscar Daoura, Ghenwa El Chawich, Maya Boutros, Nissrine El Hassan, Pascale Massiani, Ovidiu Ersen, Walid Baaziz, Franck Launay

Nickel(II) hydroxycarbonate colloids were synthesized in water by the reaction of nickel(II) with carbonate in the presence of hexadecyltrimethylammonium bromide. Then, they were dispersed onto SBA-15 affording, after calcination and reduction, a supported 3 wt% nickel(0) catalyst for the dry…

Mesoporous nickel-alumina catalysts derived from MIL-53(Al) metal-organic framework: A new promising path for synthesizing CO2 methanation catalysts

Leila Karam, Maria C Bacariza, José M Lopes, Carlos Henriques, Julien Reboul, Nissrine El Hassan, Pascale Massiani

A new synthesis route for the preparation of highly efficient and stable porous Ni-based alumina catalysts for CO2 methanation is presented. It is based on the use of MIL-53(Al), an Al-containing metal-organic framework (MOF) with high surface area, as sacrificial support. A series of Ni-Al2O3…

Effect of catalyst synthesis strategy on the structure and performance of Ni–Co bimetallic catalysts for dry reforming of methane

Yeji Gwon, Dong-Hyun Kim, Ui-Dam Jun, Bon-Jun Ku, Siranuysh Badalyan, Mansu Kim, Sandra Casale, Julien Reboul, Kyubock Lee

The design of stable and efficient catalysts for dry reforming of methane (DRM) is hindered by severe carbon deposition and metal sintering under high-temperature conditions.<p>In this study, Ni-Co bimetallic catalysts were synthesized using different strategies of catalyst synthesis-…

Bioactivation of New Harmonic Titanium Alloy to Improve and Control Cellular Response and Differentiation

André Rangel, Mylan Lam, Azziz Hocini, Vincent Humblot, Kei Ameyama, Véronique Migonney, Guy-François Dirras, Céline Falentin-Daudré

Objective: The purpose of this research article is to present the functionalization of a new titanium alloy of the system TiNbZr, by the grafting of a bioactive polymer (poly(sodium styrene sulfonate), PNaSS) using the “grafting from” technique to improve the osseointegration. The resulting grafted…

On the graphical analysis of the impedance response of passive electrodes

Mai T.T. Tran, Oumaïma Gharbi, Mark E Orazem, Bernard Tribollet, Mireille Turmine, Vincent Vivier

The analysis of the capacitive behavior of a passive electrode is often a difficult subject because the response obtained by electrochemical impedance spectroscopy (EIS) is characterized by a non-ideal behavior that we try to model by using a constant phase element (CPE) [1, 2]. In doing so, both…
