Basic reactivity of CaO: investigating active sites under operating conditions

Hugo Petitjean, Celine Chizallet, Jean-Marc Krafft, Michel Che, Helene Lauron-Pernot, Guylene Costentin

A set of CaO samples was prepared from thermal decomposition of several precursors, leading to very different surface properties. During storage, CaO samples rehydrated quickly but reversibly. Before characterization, the samples were pre-treated at 1023 K under nitrogen flow to obtain CaO as the…

Electrosynthesis of pyrrole 3-carboxylic acid copolymer films and nanotubes with tunable degree of functionalization for biomedical applications

Cecile J. Roy, Lucas Leprince, Arnaud de Boulard, Jessem Landoulsi, Vincent Callegari, Alain M. Jonas, Sophie Demoustier-Champagne

Tailoring polypyrrole (PPy), an electroactive polymer, with functional groups to which a variety of bioactive molecules can be tethered is highly attractive for building biological structures on conducting surfaces for a range of biomedical applications. In this respect, we investigate the effects…

Synthesis and grafting of a BTP derivative onto a quartz crystal microbalance for lanthanide detection

Dimitri Mercier, Nicolas Leconte, Christophe Methivier, Franck Suzenet, G?ld Guillaumet, Anne Wuillaume, Claire-Marie Pradier

The ability of bis-triazinylpyridine (BTP) molecules to complex lanthanides is well-known in solution and can be judiciously utilized to elaborate solid sensing surfaces. This was done by synthesizing a new BTP derivative and covalently anchoring it onto gold surfaces. The BTP grafting, its…

Mesoporous materials from zeolite seeds as supports for nickel tungsten sulfide active phases Part 1. Characterization and catalytic properties in hydrocracking reactions

Shuangqin Zeng, Juliette Blanchard, Michèle Breysse, Dadong Li, Hong Nie, Yahua Shib, Xintian Su

MCM-41 aluminosilicate mesostructures (Si/Al = 18) with hexagonal long-range order were assembled from protozeolitic nanoclusters (zeolite seeds) that normally nucleate the crystn. of b-zeolite (BEA). Depending on the duration of the thermal treatment leading to the zeolite seeds, different acidic…

Catalytic performances of platinum doped molybdenum carbide for simultaneous hydrodenitrogenation and hydrodesulfurization

Marek Lewandowski, Agnieszka Szymanska-Kolasa, Patrick da Costa, Celine Sayag

The hydrotreating activity of molybdenum carbide doped with platinum (0.3 wt.%) was studied and compared to that of a pure, non-modified Mo2C. 4,6-Dimethyldibenzothiophene (4,6-DMDBT, 300 ppm of S) and carbazole (100 ppm of N) were designated as model compounds and subjected to hydrodesufurization…

Self-Organization and/or Nanocrystallinity of Co Nanocrystals Effects on the Oxidation Process Using High-Energy Electron Beam

Ana Cazacu, Claudio Larosa, Patricia Beaunier, Guillaume Laurent, Paolo Nanni, Liliana Mitoseriu, Isabelle Lisiecki

The enhanced stability of Co nanocrystals (NCs) when they are highly ordered at both nanometer and micrometer scales is reported. For the first time, it is shown that both the crystalline structure of Co nanoparticles (NPs) and their 2D hexagonal organization have a significant impact on the…

Vibrational and electrical investigations of a uniaxially stretched polystyrene/carbon nanotube composite

Liliane Bokobza, Gilles Garnaud, Patricia Beaunier, Jean-Luc Bruneel

Multiwall carbon nanotube (MWCNT)/polystyrene (PS) composite materials were prepared in the absence and in the presence of a surfactant. TEM analysis reveals the formation of chains made of several nanotubes tied up together upon application of the surfactant while an almost random distribution is…

Erratum to: Surface functionalization by covalent immobilization of an innovative carvacrol derivative to avoid fungal biofilm formation

Aïcha Gharbi, Thibaut Legigan, Vincent Humblot, Sébastien Papot, Christine Imbert, Jean-Marc Berjeaud

Carvacrol, an aromatic terpenic compound, known to be antimicrobial was grafted onto gold surfaces via two strategies based on newly-synthesized cross-linkers involving either an ester bond which can be cleaved by microbial esterases, or a covalent ether link. Surface functionalizations were…
