Gold Grafted to Mesoporous Silica Surfaces, a Molecular Picture

A. Wojtaszek, I. Sobczak, M. Ziolek, Frederik Tielens

The adsorption of HAuCl(4), the typical precursor for gold grafting on metal oxide surfaces, is investigated on amorphous silica support. The adsorption of the precursor is investigated as a function of its chlorinated form, depending on the pH, using periodic DFT. The results are supported with…

Catalytic properties of AgAlBEA and AgSiBEA zeolites in H2-promoted selective reduction of NO with ethanol

Nataliia Popovych, Pavlo Kyriienko, Sergiy Soloviev, Svitlana Orlyk, Stanislaw Dzwigaj

Physicochemical properties of AgAlBEA and AgSiBEA zeolites were investigated by IR spectroscopy with pyridine, H2-TPR, XPS and diffuse reflectance UV–vis spectroscopy. Their catalytic properties were studied in the process of selective reduction of NO with ethanol and in the presence of hydrogen in…

Study of calixarenes thin films as chemical sensors for the detection of explosives

P. Montmeat, F. Veignal, C. Methivier, C.M. Pradier, L. Hairault

Calix(n)arenes (n = 4, 6, 8) are used as sensitive coatings for Quartz Crystal Microbalance (QCM)-based chemical sensors, and specially for the detection of dinitrotoluene as a model explosive molecule. Calix(n)arenes complex organic architectures were deposited by spray on gold-coated wafer…

Chimie : un vecteur vert

Jacques Maddaluno, Claire-Marie Pradier, Anne Imberty, Dominique Massiot

Les faits, longtemps sujets à discussion, sont désormais là. Le cinquième rapport du GIEC (2013) qualifie d'« extrêmement probable » un lien entre les dérèglements climatiques observés depuis 1950 et les variations de la composition de l'atmosphère terrestre provoqués par l'…

Surface Chirality of Gly-Pro Dipeptide Adsorbed on a Cu(110) Surface

Hervé Cruguel, Christophe Méthivier, Claire-Marie Pradier, Vincent Humblot

The adsorption of chiral Gly-Pro dipeptide on Cu(110) has been characterized by combining in situ polarization modulation infrared reflection absorption spectroscopy (PM-RAIRS) and X-ray photoelectron spectroscopy (XPS). The chemical state of the dipeptide, and its anchoring points and adsorption…

Targeted polyethylene glycol gold nanoparticles for the treatment of pancreatic cancer: from synthesis to proof-of-concept in vitro studies

Jolanda Spadavecchia, Dania Movia, Caroline Moore, Ciaran Manus Maguire, Hanane Moustaoui, Sandra Casale, Yuri Volkov, Adriele Prina-Mello

The main objective of this study was to optimize and characterize a drug delivery carrier for doxorubicin, intended to be intravenously administered, capable of improving the therapeutic index of the chemotherapeutic agent itself, and aimed at the treatment of pancreatic cancer. In light of this…

Crystalline Molybdenum Oxide Thin-Films for Application as Interfacial Layers in Optoelectronic Devices

André Luis Fernandes Cauduro, Roberto dos Reis, Gong Chen, Andreas K. Schmid, Christophe Méthivier, Horst-Günter Rubahn, Léo Bossard-Giannesini, Hervé Cruguel, Nadine Witkowski, Morten Madsen

The ability to control the interfacial properties in metal-oxide thin films through surface defect engineering is vital to fine tune their optoelectronic properties and thus their integration in novel optoelectronic devices. This is exemplified in photovoltaic devices based on organic, inorganic or…

On the influence of water traces on the acidity measurement of amorphous aluminosilicates

Juliette Blanchard, Jean-Marc Krafft, Colin Dupont, Céline Sayag, Toshikazu Takahashi, Hiroyuki Yasuda

For the measurement of their acidity, amorphous aluminosilicates are beforehand treated at temperature of 450 • C or higher in order to remove water adsorbed on their surface. We will show in this study that, during the standard course of an acidity measurement by low temperature CO adsorption,…

High selectivity of TaSiBEA zeolite catalysts in 1,3-butadiene production from ethanol and acetaldehyde mixture

Pavlo I. Kyriienko, Olga V. Larina, Sergiy O. Soloviev, Svitlana M. Orlyk, Stanislaw Dzwigaj

New tantalum-silica based zeolite catalysts (TaSiBEA) were applied in this work for 1,3-butadiene production from ethanol. Tantalum incorporation into vacant T-atom sites of the SiBEA zeolites framework as mononuclear Ta(V) allowed preparing highly selective catalysts for ethanol/acetaldehyde…
