Covalent Transition Metal Borosilicides: Reaction Pathways in Molten Salts for Water Oxidation Electrocatalysis

Daniel Janisch, Fernando Igoa Saldaña, Edouard de Rolland Dalon, Carlos V. M. Inocêncio, Yang Song, Pierre-Olivier Autran, Antoine Miche, Sandra Casale, David Portehault

The properties of transition metal borides and silicides are intimately linked to the covalent character of the chemical bonds within their crystal structures. Bringing boron and silicon together within metal borosilicides can then engender different competing covalent networks and complex charge…

Atomic Scale Observation of the Structural Dynamics of Supported Gold Nanocatalysts under 1,3‐Butadiene by in situ Environmental Transmission Electron Microscopy

Abdallah Nassereddine, Laurent Delannoy, Christian Ricolleau, Catherine Louis, Alloyeau D., Guillaume Wang, Qing Wang, Hazar Guesmi, Jaysen Nelayah

Supported gold catalysts have been reported to exhibit exceptional selectivity towards the desirable product, an alkene, in chemoselective hydrogenation of highly unsaturated alkynes and alkadienes. However, insights on the interactions between the gold nanoparticles and the 1,3‐butadiene…

Engineering of Antimicrobial Surfaces by Using Temporin Analogs to Tune the Biocidal/antiadhesive Effect

Pierre-Carl Oger, Christophe Piesse, Ali Ladram, Vincent Humblot

Proliferation of resistant bacteria on biomaterials is a major problem leading to nosocomial infections. Due to their broad-spectrum activity and their ability to disrupt bacterial membranes through a rapid membranolytic mechanism, antimicrobial peptides (AMPs) are less susceptible to the…

Electrochemical deposition of ZnO thin films in aprotic ionic liquids: Effect of the cationic alkyl-chain-length

Rita Khalil, Mirella Azar, Ibrahim Bou Malham, Mireille Turmine, Vincent Vivier

Zinc oxide (ZnO) is a semiconductor with various physicochemical properties allowing its use in a wide range of technological applications. The aim of this work is to study nanocrystalline ZnO thin-film deposited using zinc salt which is dissolved in pure ionic liquids (ILs). The latter play a dual…

Ce- and Y-Modified Double-Layered Hydroxides as Catalysts for Dry Reforming of Methane: On the Effect of Yttrium Promotion

Katarzyna Świrk, Magnus Rønning, Monika Motak, Patricia Beaunier, Patrick da Costa, Teresa Grzybek

Ce- and Y-promoted double-layered hydroxides were synthesized and tested in dry reforming of methane (CH4/CO2 = 1/1). The characterization of the catalysts was performed using X-ray fluorescence (XRF), X-ray diffraction (XRD), N2 sorption, temperature-programmed reduction in H2 (TPR-H2),…

The Prevailing Role of Hotspots in Plasmon-Enhanced Sum-Frequency Generation Spectroscopy

Laetitia Dalstein, Christophe Humbert, Maroua Ben Haddada, Souhir Boujday, Grégory Barbillon, Bertrand Busson

The plasmonic amplification of nonlinear vibrational sum frequency spectroscopy (SFG) at the surfaces of gold nanoparticles is systematically investigated by tuning the incident visible wavelength. The SFG spectra of dodecanethiol-coated gold nanoparticles chemically deposited on silicon are…

A Hydrothermal-Sedimentary Context for the Origin of Life

Frances Westall, Keyron Hickman-Lewis, Nancy Hinman, Pascale Gautret, Kathleen A Campbell, Jean-Gabriel Bréhéret, Frédéric Foucher, Axelle Hubert, Stephanie Sorieul, Avinash Vicholous Dass, Terence P. Kee, Thomas Georgelin, André Brack

Critical to the origin of life are the ingredients of life, of course, but also the physical and chemical conditions in which prebiotic chemical reactions can take place. These factors place constraints on the types of Hadean environment in which life could have emerged. Many locations, ranging…
