Potential of electrochemical techniques (macro and microelectrodes) in fronth flotation concentration of sulfide minerals, Potencialidade das técnicas eletroquímicas (macro e microeletrodos) na concentração por flotação de minerais sulfetados

Marina Martins Mennucci, Tatiana Mallet Machado, Vincent Vivier, Hercílio Gomes De Melo, Jean Vicente Ferrari

ABSTRACT The interactions between sulfide minerals and the chemistry of the exposure medium, from the grinding process to the flotation pulp, can be electrochemical and/or galvanic and influence the hydrophobicity of their surfaces, resulting in different levels of recovery. In the literature, most…, RESUMO As interações entre os minerais sulfetados e a química do meio de exposição, desde o processo de moagem dos minérios até a polpa de flotação, podem ser de caráter eletroquímico e/ou de natureza galvânica e influenciam a hidrofobicidade de suas superfícies, resultando em diferentes níveis de…

Nature of the active sites in CO oxidation on FeSiBEA zeolites

Ireneusz Kocemba, Jacek Rynkowski, Jacek Gurgul, Robert P. Socha, Kazimierz Łątka, Jean-Marc Krafft, Stanislaw Dzwigaj

FeSiBEA zeolites containing 1 wt% of iron were prepared by a two-step postsynthesis method in acidic (pH = 2.6) (Fe1.0SiBEA(w)) and alkaline (pH = 10) (Fe1.0SiBEA(p)) conditions. The structure of the studied materials, their acidity as well as the nature and environment of iron present in the…

A combined experimental and theoretical study of the simultaneous occupation of SIa and SI0 sites in fully dehydrated K-LSX

Hazar Guesmi, Pascale Massiani, Habiba Nouali, Jean-Louis Paillaud

In the case of fully potassium exchanged X and LSX faujasites, it was reported from a single crystal X-ray study on zeolite X and preliminary powder X-ray diffraction (PXRD) study on zeolite LSX that K+ ions can be found concomitantly in both sites I and I' with partial or full occupancy of…

Intensity-energy response function of Al/Cr-K α x-ray photoemission instruments: An inter-laboratory study

David Alamarguy, Damien Aureau, Thierry Conard, Nicolas Gauthier, Frédéric Georgi, Stéphane Guilet, Samar Hajjar-Garreau, Olivier Heintz, Guillaume Monier, Christophe Méthivier, Hervé Montigaud, Samantha Soulé, Olivier Renault, Rémi Lazzari

The question of the intensity-energy response of photoemission spectrometers has been approached through a round-robin involving 13 instruments working with low (Al/Mg-K) and high (Cr-K) energy photon sources. An algorithm based on the analysis of inelastic background previously proposed [S. Guilet…

PET waste as organic linker source for the sustainable preparation of MOF-derived methane dry reforming catalysts

Leila Karam, Arianna Miglio, Stefania Specchia, Nissrine El Hassan, Pascale Massiani, Julien Reboul

A catalyst made of Ni 0 nanoparticles highly dispersed on a lamellar alumina support was prepared by an environmentally-friendly route. The latter involved the synthesis of an aluminum-containing metalorganic framework (MOF) MIL-53(Al) in which the linkers were derived from the depolymerization of…

Surfaces for hearts: Establishing the optimum plasma surface engineering methodology on polystyrene for cardiac cell engineering

Maria Kitsara, Dimitrios Kontziampasis, Efi Bolomiti, Alexandre Simon, Panagiotis Dimitrakis, Antoine Miche, Georgios Kokkoris, Onnik Agbulut, Vincent Humblot

Plasma surface modification is a popular method for improving cell culture on surfaces, and polystyrene (PS) is literature’s material of choice. This study identifies the optimum plasma treatment for promoting normal cardiac cell behaviour during culture. PS slides were plasma-treated with O2, N2,…

The impact of the hydrodechlorination process on the physicochemical properties of bimetallic Ag-CuBeta zeolite catalysts

A. Śrębowata, Izabela I. Kamińska, S. Casale, D. Brouri, C. Calers, Stanislaw Dzwigaj

Beta zeolites with two Si/Al ratios of 17 and 1300 were used for synthesis of Ag2.0Cu2.0HAlBeta and Ag2.0Cu2.0SiBeta zeolites by conventional wet impregnation and two-step postsynthesis methods, respectively. The calcination of Ag2.0Cu2.0HAlBeta and Ag2.0Cu2.0SiBeta at 773 K for 3 h in air led to…
