Direct Observation of the Surface Topography at High Temperature with SEM

Renaud Podor, X. F Le Goff, Joseph Lautru, H.P. Brau, Mathias Barreau, Xavier Carrier, Jerôme Mendonça, Dorian Nogues, Antoine Candeias

High-temperature scanning electron microscopy allows the direct study of the temperature behavior of materials. Using a newly developed heating stage, tilted images series were recorded at high temperature and 3D images of the sample surface were reconstructed. By combining 3D images recorded at…

Preparation of niobium-based oxygen carriers by polyol-mediated process and application to chemical-looping reforming

Pedro Henrique Lopes Nunes Abreu dos Santos, Sophie Nowak, Stéphanie Lau-Truong, Juliette Blanchard, Patricia Beaunier, José Augusto Jorge Rodrigues, Roberta Brayner

New niobium-based oxygen carriers were prepared adopting polyol-mediated process. Four different polyols were used (diethylene glycol, triethylene glycol, tetraethylene glycol, and 1,2-propanediol) and four different quantities of water (0 mL, 1 mL, 10 mL, 30 mL, with a total volume of 80 mL of…

Giant Exchange-Bias in Polyol-Made CoFe2O4-CoO Core-Shell Like Nanoparticles

Nancy Flores-Martinez, Giulia Franceschin, Thomas Gaudisson, Patricia Beaunier, Nader Yaacoub, Jean-Marc Greneche, Raul Valenzuela, Souad Ammar

Cobalt ferrite ferrimagnetic nanoparticles (NPs) are prepared and used in this work as seeds to grow a thin antiferromagnetic poly- and nanocrystalline CoO shell. The major purpose is to study systematically the characteristics of the as-produced powders, making emphasis on their internal…

Phosphate Boosts Nonhydroxyl Radical Species Production upon Air Oxidation of Magnetite and Iron Sulfides at Neutral pH

Guillaume Morin, Frédéric Averseng, Xavier Carrier, Pierre Le Pape, Yishan Du, Yusheng Honge, Elora Bourbon, Giuseppe Sportelli, Tiago A da Silva, Alberto Mezzetti, Camille Baya, Thierry Allard, Jessica Brest, Maryse Rouelle

Heterogeneous Fenton-like reactions using O2 as sole oxidant are gaining interest for designing organic contaminant degradation in soils and groundwaters, since they may provide alternatives to current processes involving strong oxidants. Indeed, several Fe(II)-bearing oxide and sulfide mineral…
