Assessing the potential of xNi-yMg-Al2O3 catalysts prepared by EISA-one-pot synthesis towards CO2 methanation: An overall study

Leila Karam, M. Carmen Bacariza, José David Lopes, Carlos Henriques, Pascale Massiani, Nissrine El Hassan

Mesoporous xNi-yMg-Al2O3 catalysts prepared by combined evaporation induced self-assembly (EISA) and one-pot techniques were tested in CO2 methanation reaction. All calcined/reduced materials were characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD), N2 physisorption,…

Effect of SAM chain length and binding functions on protein adsorption: β-Lactoglobulin and apo-transferrin on gold.

Erin E. Bedford, Vincent Humblot, Frank X. Gu, Claire-Marie Pradier

Controlled immobilization of proteins is crucial in many applications, including biosensors. Allergen biosensing, for example, requires molecular recognition of suitably immobilized proteins by specific antibodies and sensitive measurement of this interaction. Self-assembled monolayers (SAMs),…

An UV-Visible study of the stability of the ruthenium hexaammine cation in BEA zeolites—comparison with NaY

Pascale Massiani, Perla Castillo-Villalon, Jorge Ramirez, Marie-Jeanne Peltre, Catherine Louis

A series of Ru/zeolites with Ru content in the range of 1–7 wt.% was prepared by cationic exchange in an aqueous Ru(NH3)6Cl3 solution, at room temperature, of two H–BEA (different particle sizes but same Si/Al ratio of 13), a Cs–BEA (Si/Al 1⁄4 13) and a NaY (Si/Al 1⁄4 2.4), zeolitic supports. The…

Stabilization of hexagonal close-packed metallic nickel for alumina-supported systems prepared from Ni(II) glycinate

Eric Marceau, Vicente Rodriguez-Gonzalez, Michel Che, Patricia Beaunier, Cyrille Train

The decomposition in flowing argon of the neutral complex [NiII(glycinate)2(H2O)2] leads to a mixture of face-centered cubic (fcc) and hexagonal close-packed (hcp) metallic nickel. The latter is the main phase when the Ni(II) complex is supported on alumina. Unlike most hexagonal Ni phases…

Tuning the load in gold and magnetic nanoparticles in nanogels through their design for enhanced dual magneto-photo-thermia

Esther Cazares-Cortes, Claire Wilhelm, Jose Efrain Perez, Ana Espinosa, Sandra Casale, Aude Michel, Ali Abou-Hassan, Christine Ménager

We describe a novel synthesis allowing to enhance the load in magnetic nanoparticles and gold nanorods in nanogels. Two different structures, simple cores and core-shells were synthesized and their heating properties upon alternating magnetic field or laser exposure are compared. Remarkably, the…

Oxidation and Surface Segregation Behavior of a Pt–Pd–Rh Alloy Catalyst

Paul A. J. Bagot, Karen Kruska, Daniel Haley, Xavier Carrier, Eric Marceau, Michael. P. Moody, George D. W. Smith

Platinum gauze catalysts are used extensively in the production of nitricacid from ammonia, where they are subject to harsh operating conditions combiningelevated temperatures and oxidizing environments. These cause significant loss of metalspecies as volatile oxides. How different metallic species…

Pseudoaneurysm of anterior tibial artery following a diaphyseal fracture ă of the tibia mimicking a malignant bone tumor

Pierre Sautet, Elie Choufani, Philippe Petit, Franck Launay, Jean-Luc Jouve, Sebastien Pesenti

Pseudoaneurysms of the lower limb are rare and frequently iatrogenics ă complications. Closed traumas are likely to generate lesions of the ă arterial wall, which generally become symptomatic at a later stage. The ă diagnosis of such vascular lesion is difficult because the ă symptomatology and the…

Determination of Integrated Molar Absorption Coefficients for Gaseous Phenol Infrared Bands and Influence of Water Vapor on Their Values

Thomas Onfroy, Olivier Marie

The integrated molar absorption coefficients for ν(OH) (3655 cm-1), δ(OH) (Q branch at 1176 cm-1 or whole bands), [ν(CCring) + δ(OH)] (Q branch at 1344 cm-1 or whole bands) and γ(CH) (752 cm-1) were determined at 342 K, by recording infrared spectra of pure gaseous phenol at different partial…

Electron conductive self-assembled hybrid low-molecular weight glycolipid-nanosilver gels

Korin Gasia Ozkaya, Othmane Darouich, Hynd Remita, Isabelle Lampre, Lionel Porcar, Alain Carvalho, M. Schmutz, Sandra Casale, Christel Laberty-Robert, Niki Baccile

Low-molecular weight (LMW) hydrogels are gaining interest over macromolecular gels due to their reversible, dynamic and stimuli-responsive nature. They are potentially interesting functional materials for advanced applications such as catalysis, nanoelectronics or regenerative medicine. One common…
