Evaluation and application of a new scintillator‐based heat‐resistant back‐scattered electron detector during heat treatment in the scanning electron microscope

Renaud Podor, J. Mendonça, J. Lautru, H.P. Brau, D. Nogues, A. Candeias, P. Horodysky, A. Kolouch, M. Barreau, X. Carrier, N. Ramenatte, S. Mathieu, M. Vilasi

A new high-temperature detector dedicated to the collection of backscattered electrons is used in combination with heating stages up to 1050°C, in high-vacuum and low-vacuum modes in order to evaluate its possibilities through signal-to-noise ration measurements and different applications. Four…

Influence of the ultrasound power density in the ultrasound-assisted synthesis of Ni-based LDH catalysts for CO2 methanation

Michel Obeid, Christophe Poupin, Madona Labaki, Sharad Gupta, Samer Aouad, François Delattre, Ferdaous Ben Romdhane, François Devred, Eric Gaigneaux, Josefine Schnee, Edmond Abi-Aad

Ultrasound-assisted co-precipitation method was used to synthesize Ni-LDH based catalysts for CO2 methanation. The influence of ultrasonic irradiation power density (90, 180, 270, and 360 W·L−1) on the physico-chemical properties of the catalysts as well as on their catalytic behavior was studied…

A new concept of a proton battery based on protic ionic liquid

Ekaterina Kurchavova, Julie Chan, Junxian Zhang, Fermin Cuevas, Mickael Mateos, Judith Monnier, Vincent Vivier, Mireille Turmine

Nowadays, the most effective and widely spread energy storage systems are Li-ion batteries. However, they have some drawbacks such as high price, flammability, temperature limitation, reduced availability of Li resources on the Earth, etc.[1]. Thus, the development of new competitive systems is…

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…

Sequential and Time-Controlled Sol-Gel Transitions by the Mechanical Switching of Molecular Tweezers

Pablo Msellem, Geoffrey Groslambert, Louise Miton, Mickaël Pomes-Hadda, Nathan van Zee, Clément Guibert, Guillaume Vives

Controlling the motion of molecular machines to influence higher-order structures is well-established in biological systems but remains a significant challenge for synthetic analogs. Herein, we aim to harness the mechanical switching of switchable molecular tweezers to modulate their self-assembly…

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.…

Erratum to: Surface functionalization by covalent immobilization of an innovative carvacrol derivative to avoid fungal biofilm formation

Aïcha Gharbi, Thibaut Legigan, Vincent Humblot, Sébastien Papot, Christine Imbert, Jean-Marc Berjeaud

Carvacrol, an aromatic terpenic compound, known to be antimicrobial was grafted onto gold surfaces via two strategies based on newly-synthesized cross-linkers involving either an ester bond which can be cleaved by microbial esterases, or a covalent ether link. Surface functionalizations were…

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…
