Deciphering the improvement in (H2-)C3H6-SCR performance of Ag/Al2O3 catalysts prepared from warm-water-treated alumina: A NMR-assisted identification of the Ag anchoring sites of the alumina support

Yannick Millot, Guylène Costentin, Clémence Rodigue, Thomas Onfroy, Cyril Thomas

Lean exhausts aftertreatment has been the subject of numerous investigations due to ever stringent regulations on pollutants emissions such as that of NOx. Among aftertreatment technologies, the selective catalytic reduction of NOx by the hydrocarbons (HC-SCR) has been studied intensively, in…

Revisiting active sites in heterogeneous catalysis: Their structure and their dynamic behaviour

Jacques C. Vedrine

This short review article aims at revisiting the description of active sites in heterogeneous catalysis on solid surfaces and their role in catalyst activity and selectivity. Special emphasis is brought to: (i) structure of the solid surface; (ii) importance of active site isolation on the surface;…

Silver-Based Plasmonic Nanoparticles for and Their Use in Biosensing

Alexis Loiseau, Victoire Asila, Gabriel Boitel-Aullen, Mylan Lam, Michèle Salmain, Souhir Boujday

The localized surface plasmon resonance (LSPR) property of metallic nanoparticles is widely exploited for chemical and biological sensing. Selective biosensing of molecules using functionalized nanoparticles has become a major research interdisciplinary area between chemistry, biology and material…

Visible Light Excitation of Poly‐( para ‐Phenylene Ethynylene) Enables Heterogeneous Photocatalytic Oxidations of Amines in Flow

Basile Weyl, Gabriel Goujon, Lucas Raggio, Emmanuelle Demey, Joelle Vinh, Jean‐baptiste d'Espinose de Lacaillerie, Jean‐marc Krafft, Benjamin Laroche

Abstract Heterogeneous visible light photocatalysis is a compelling approach to address sustainability in synthetic photochemistry. However, the use of solid‐state photocatalysts remains very unpopular in organic synthesis because of their limited accessibility and the black‐box effect associated…

Effect of Nontronite Smectite Clay on the Chemical Evolution of Several Organic Molecules under Simulated Martian Surface Ultraviolet Radiation Conditions

Olivier Poch, Maguy Jaber, Fabien Stalport, Sophie Nowak, Thomas Georgelin, Jean-François Lambert, Cyril Szopa, Patrice Coll

Most of the phyllosilicates detected at the surface of Mars today are probably remnants of ancient environments that sustained long-term bodies of liquid water at the surface or subsurface and were possibly favorable for the emergence of life. Consequently, phyllosilicates have become the main…

Surface plasmon resonance: signal amplification using colloidal gold nanoparticles for enhanced sensitivity

Sabine Szunerits, Jolanda Spadavecchia, Rabah Boukherroub

Among all the detection methods developed for bioassays, optical-based approaches are the most popular techniques. A widely used and accepted bioanalytical technique for routine characterization of molecular recognition events at a solid interface is surface plasmon resonance (SPR) spectroscopy.…

Role of active components of an Ag/Al2O3/cordierite catalyst in selective reduction of NO by ethanol

N. A. Popovich, P. I. Kiriienko, S. Solov’ev, S. Orlik, S. Dzwigaj

We show that the activity of silver/aluminum oxide catalysts in selective reduction of nitrogen oxides by ethanol increases as the Al2O3 content increases, and is determined by the optimal silver content for which Ag + cations and Ag n nanoclusters form on the Al2O3 surface. The role of silver in…

Determination of dielectric properties of mimicking biological tissues by electrochemical impedance spectroscopy

Mado Abraham, Sylvain Feruglio, Ahmed Hamraoui, Hakeim Talleb, Vincent Vivier, Kieu Ngo

Tissue-mimicking materials are widely developed and used as substitutes in many medical branches, including surgical procedures, medical imaging, machine calibration, training, and simulations. Usually, these materials are fabricated either by chemical synthesis or additive manufacturing (3D…
