Permanently hydrophilic, piezoelectric PVDF nanofibrous scaffolds promoting unaided electromechanical stimulation on osteoblasts

Maria Kitsara, Andreu Blanquer, Gonzalo Murillo, Vincent Humblot, Sara de Bragança Vieira, Carme Nogués, Elena Ibáñez, Jaume Esteve, Leonardo Barrios

Biomimetic functional scaffolds for tissue engineering should fulfil specific requirements concerning structural, biochemical and electro-mechanical characteristics, depending on the tissue that they are designed to resemble. In bone tissue engineering, piezoelectric materials based on poly(…

Improvement of the Catalytic Performances of SBA‐15 in the Formylation of Aniline upon the Introduction of Template‐Free Nano‐Faujasite in Its Synthesis Gel

Karima Baghdad, Mohammed Abdelkrim Hasnaoui, Franck Launay

Faujasite nanoparticles with average size of 10–40 nm were obtained without any organic structure directing agents (Green synthesis), then used as precursors for the synthesis of NaY/SBA-15 composites. Two types of composites were obtained with meso/micro porosity (C1 and C2).The inorganic salt,…

Activity of molybdenum and tungsten oxycarbides in hydrodenitrogenation of carbazole leading to isomerization secondary reaction of bicyclohexyl. Results using bicyclohexyl as feedstock

Marek Lewandowski, Agnieszka Szymańska-Kolasa, Céline Sayag, Gérald Djéga-Mariadassou

The catalytic activities of bulk tungsten and molybdenum oxycarbides, (W2C and Mo2C) have been specifically studied in the isomerization occurring during the hydrodenitrogenation (HDN) of carbazole. The two catalysts have been characterized by several physico-chemical techniques such as X-Ray…

Plasma Assisted Catalyst for NOx Remediation from Lean Gas Exhaust

Ahmed Khacef, Patrick da Costa, Gérald Djéga-Mariadassou

A non-thermal plasma (NTP) reactor was coupled with a three-function catalyst in order to verify the nature of the effect of the plasma on the catalytic process. A mixture of NO/O2/hydrocarbons in N2 was used as a lean model exhaust gas composition. The plasma was found to perform two of the three…

Porosity Design of Shaped Zeolites for Improved Catalyst Lifetime in the Methanol-to-Hydrocarbons Reaction

Rogéria Bingre, Renna Li, Qiang Wang, Patrick Nguyen, Thomas Onfroy, Benoit Louis

Additional porosity, such as meso-and macropores, was introduced in zeolite extrudates with the intention intuit of improving the effective diffusivity of the catalysts. The samples were characterized in depth by nitrogen adsorption-desorption, mercury intrusion porosimetry, ammonia temperature…

Promoting Ag/Al2O3 Performance in Low-Temperature H2-C3H6-SCR by Thermal Pretreatment of γ-Alumina in Water

Tesnim Chaieb, Laurent Delannoy, Catherine Louis, Cyril Thomas

The present work highlights for the first time that a thermal treatment of γ-Al2O3 in water at 80 °C for 24 h prior to Ag deposition (Ag/Al2O3-OH) leads to a drastic enhancement of H2-C3H6-SCR performance at low temperature. This enhancement is attributed to the higher NOx coverage on Ag/Al2O3-OH…

LRS-1, a new delaminated phyllosilicate material with high acidity », Chem. Mater., 18(1), 34-40 (2006).

Bachar Zebib, Jean-François Lambert, Juliette Blanchard, Michèle Breysse

Well-crystallized samples of the phyllosilicate magadiite have been synthesized in their sodic form, both purely silicic and with an Al/Si ratio of 30. They have been delaminated by a procedure consisting of CTMA+ swelling in the presence of TPAOH, sonication, and calcination at 700°C to remove the…
