Impregnation of .gamma.-Alumina with Ni(II) or Co(II) Ions at Neutral pH: Hydrotalcite-Type Coprecipitate Formation and Characterization

Jean-Baptiste d'Espinose de la Caillerie, Maggy Kermarec, Olivier Clause

The adsorption of Co(II) or Ni(II) ammine complexes from aqueous solutions onto y-alumina at neutral or near neutral pH (7 < pH < 8.2) and ambient temperature is investigated as a function of the ion concentration in the impregnating solutions, the contact and aging times, and the drying…

Recent advances in aptasensors based on graphene and graphene-like nanomaterials

Jianfeng Ping, Yubin Zhou, Yuanyuan Wu, Vladislav Papper, Souhir Boujday, Robert S. Marks, Terry W.J. Steele

Graphene and graphene-like two-dimensional nanomaterials have aroused tremendous research interest in recent years due to their unique electronic, optical, and mechanical properties associated with their planar structure. Aptamers have exhibited many advantages as molecular recognition elements for…

2D Monolayer of 1T' Phase of Alloyed WSSe from Colloidal Synthesis

Ashkan Shahmanesh, Davide Romanin, Corentin Dabard, Sang-Soo Chee, Charlie Gréboval, Christophe Methivier, Mathieu G Silly, Julien Chaste, Matthieu Bugnet, Debora Pierucci, Abdelkarim Ouerghi, Matteo Calandra, Emmanuel Lhuillier, Benoit Mahler

We explore the colloidal growth of monolayers of WSSe alloy in their 1T' phase with various Se content. We develop a synthetic procedure leading to reduced aggregation of the flakes. The presence of a narrow band-gap close to the top of the valence band has been evidenced combining…

Fate of Organic Molecules in the Mars Regolith Under UV Radiation Deduced from the MOMIE Laboratory Experiment

Cyril Szopa, Patrice Coll, Fabien Stalport, Olivier Poch, Maguy Jaber, Jean-François Lambert, Laura Rouquette, Jérôme Lasne

Among bioindicators or biosigna- tures, organic molecules present on Mars could be re- trieved in the regolith near the surface due to erosion of rocks and gardening of the soil from meteorites bom- bardment through the Mars history. Once their, the organic molecules are submitted to the harsh…

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…

Proving ligand structure-reactivity correlation on multinuclear copper electrocatalysts supported on carbon black for the oxygen reduction reaction

Ricardo Venegas, Karina Muñoz-Becerra, Sophie Juillard, Lin Zhang, Rubén Oñate, Ingrid Ponce, Vincent Vivier, Francisco J Recio, Carlos M Sánchez-Sánchez

Bioinspired transition-metal catalysts seek to mimic the specific active site of metalloenzymes, as the multicopper oxidase, that can efficiently reduce dioxygen to water via a complete 4-electrons mechanism at low overpotential. However, the multicopper oxidase enzymes lack stability under…

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…
