Effect of the activation temperature on the state of gold supported on titania: An FT-IR spectroscopic study

Tz. Venkov, Katia Fajerwerg, L. Delannoy, Hr. Klimev, K. Hadjiivanov, C. Louis

The effect of the pre-treatment conditions on the evolution of gold species on an Au/TiO2 sample prepared by deposition–precipitation with urea has been followed by FT-IR spectroscopy of adsorbed CO. Gold is in the form of Au3+ species on the as-prepared sample and is not affected by evacuation at…

Bioactive peptides grafted silicone dressings: A simple and specific method

Coline Pinese, Said Jebors, Pierre-Emmanuel Stoebner, Vincent Humblot, Pascal Verdié, Léa Causse, Xavier Garric, Hubert Taillades, Jean Martinez, Ahmad Mehdi, Gilles Subra

The need for bioactive dressings increases with the population aging and the prevalence of chronic diseases. In contrast, there are very few dressings on the market which are designed to display a chosen bioactivity. In this context, we investigated the surface-functionalization of silicone wound…

Rational design of a CO2-resistant toluene hydrogenation catalyst based on FT-IR spectroscopy studies

Julien Scalbert, Cécile Daniel, Yves Schuurman, Cyril Thomas, Frédéric C. Meunier

Rhodium highly dispersed on alumina becomes partly poisoned by strongly bound CO when used for toluene hydrogenation at 348 K in the presence of CO2. Operando FT-IR analysis enabled to observed CO(ads) build up over the sample, while no CO(gas) could be measured in the reactor effluent. Analyses…

Introduction to Clay–Polymer Nanocomposites (CPN)

F Bergaya, Christian Detellier, Jean-François Lambert, G Lagaly

Clay mineral–polymer nanocomposites were described for the first time in 1993. Since that date, they were the subject of thousands of research papers. Clay mineral–polymer nanocomposites must be carefully distinguished from microcomposites and intercalated composites. The following chapters…

Approach for Plasmonic Based DNA Sensing: Amplification of the Wavelength Shift and Simultaneous Detection of the Plasmon Modes of Gold Nanostructures

Jolanda Spadavecchia, Alexandre Barras, Joël Lyskawa, Patrice Woisel, William Laure, Claire-Marie Pradier, Rabah Boukherroub, Sabine Szunerits

In this article, the detection of DNA hybridization taking advantage of the plasmonic properties of gold nanostructures is described. The approach is based on the amplification of the wavelength shift of a multilayered localized surface plasmon resonance (LSPR) sensor interface upon hybridization…

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…
