UHV Deposition of the Gly-Pro Dipeptide on Cu(110) by Sublimation or Electrospray Ionization

Christophe Méthivier, Vincent Humblot, Claire-Marie Pradier

While most of the peptide adsorption studies, in vacuum, are achieved by sublimation, we demonstrate here the possible use of electrospray ionization (ESI) to deposit entire peptides, possibly surrounded by solvated ions, on a surface in ultra high vacuum (UHV) conditions. This paper is then…

Carbon nanowalls functionalization for efficient O2 reduction catalyzed by laccase using design of experiment

Achraf Blout, Jérôme Pulpytel, Shinsuke Mori, Farzaneh Arefi-Khonsari, Christophe Méthivier, Alain Pailleret, Claude Jolivalt

An enzymatic biofuel cell cathode was elaborated by nano-structuration and functionalization of graphite using two consecutive plasma treatments before immobilization of laccase as a biocatalyst to perform oxygen reduction reaction (ORR) by direct electron transfer ((DET). Nano-structuration of…

CO2 valorization using epoxides under mild conditions

Viviana Contreras Moreno, Lionel Estel, Laurent Bischoff, Vincent Levacher, Marie-Pierre Denieul, Alain Ledoux, Salim Derrouiche

Carbon dioxide is the major greenhouse gas suspected to produce the climatic change. In order to reduce the emissions of CO 2 , several ways have been studied like capture process, geological storage and valorization. Recently one of the most important studies is concentrated on chemical…

Experimental Evidence of the Mechanism of Selective Catalytic Reduction of NO with NH 3 over Fe-Containing BEA Zeolites

Paweł Boroń, Małgorzata Rutkowska, Barbara Gil, Bartosz Marszałek, Lucjan Chmielarz, Stanislaw Dzwigaj

Various temperature-programmed techniques were used as tools in mechanistic studies of selective catalytic reduction (SCR) of NO with ammonia in the presence of Fe-containing BEA zeolites. Moreover, FTIR studies of adsorbed NH3 and NO were conducted to determine the interactions of reactants with…

Tunable physics through coordination chemistry: formation on oxide surface of Ti and Al chelates with 3-hydroxyflavone capable of electron injection and light emission

Getachew Solomon, Anton Landström, Silvia Rotta Loria, Eleonora Bolli, Alberto Mezzetti, Anna Facibeni, Sandro Cattarin, Alessio Mezzi, Stefano Protti, Saulius Kaciulis, Margherita Zavelani-Rossi, Isabella Concina

The optoelectronic features of 3-hydroxyflavone (3HF) self-assembled on the surface of an n-type semiconducting metal oxide (TiO2) and an insulator (Al2O3) are herein investigated. 3HF molecules use the coordinatively unsaturated metal ions present on the oxide surface to form metal complexes,…

Influence of the grafting process on the orientation and the reactivity of azide-terminated monolayers onto silica surface

Nisreen Al-Hajj, Yannick Mousli, Antoine Miche, Vincent Humblot, Julien Hunel, Karine Heuze, Thierry Buffeteau, Emilie Genin, Luc Vellutini

Click chemistry is widely used in materials and surface science for its high efficiency, ease of use and high yields. Azide-terminated SAMs have been prepared successfully by using three different deposition methods (postfunctionalization and direct grafting by immersion as well as spin coating).…

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…

Impact of nontronite on the evolution of organic molecules at the surface of Mars

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

Several evidences suggest that early Mars offered favorable conditions for long-term sustaining water. As a consequence, we can assume that in those days, endogenous chemical processes, or even primitive life, may have produced organic matter on Mars. Moreover, exogenous delivery from small bodies…
