A common precursor to both prebiotic and biological pathways to RNA nucleotides

Andrea Pérez-Villa, Thomas Georgelin, Jean-François Lambert, Marie-Christine Maurel, François Guyot, A. Marco Saitta, Fabio Pietrucci

Understanding the mechanism of spontaneous formation of ribonucleotides under realistic prebiotic conditions is a key open issue of origins-of-life research. In cells, de novo and salvage nucleotide enzymatic synthesis combines 5-phospho-α-D-ribose-1-diphosphate (α-PRPP) and nucleobases.…

Design of label-free immunosensors : from surface functionalization to analyte detection, Développement d’immunocapteurs “label-free” : de la fonctionnalisation à la détection d’analyte

Yacine Mazouzi

Rapid detection of analytes is crucial in today's society, as illustrated by the recent development of SARS-Cov2-related biosensors. The design of a biosensor begins with the functionalization of the transducer surface, followed by the controlled immobilization of the bioreceptor and finally…, La détection rapide d’analytes est cruciale dans la société actuelle, comme l'illustre le développement récent de biocapteurs liés au SARS-Cov2. La conception d’un biocapteur débute par la fonctionnalisation de la surface du transducteur, suivie par la maitrise de l’immobilisation du…

Control of calcium accessibility over hydroxyapatite by post-precipitation steps: influence on the catalytic reactivity toward alcohols

Manel Ben Osman, Sarah Diallo Garcia, Jean-Marc Krafft, Christophe Methivier, Juliette Blanchard, Tetsuya Yoshioka, Jun Kubo, Guylène Costentin

Hydroxyapatites are increasingly used as heterogeneous catalysts since they present atypical behaviours for many acid base reactions. The aim of this study was to discuss the possible involvement of Ca2+ Lewis and/or PO–H Brønsted acid sites belonging to the hydroxyapatite system in the conversion…

Adsorption of a chiral modifier on an oxide surface: Chemical nature of tartaric acid on rutile TiO2 (110)

E. Meriggio, R. Lazzari, S. Chenot, P. David, C. Methivier, X. Carrier, G. Cabailh, V. Humblot

Tartaric acid (TA) is one of the most known chiral modifier used in heterogeneous enantioselective catalysis and understanding how it interacts with oxide supports is of significant importance for the design of efficient supported metal catalysts. This work presents a detailed surface science…

Adsorption of bromothymol blue (BTB) dye using four zeolites as adsorbent

Imene Benchikh, Mohamed Serier, Franck Launay, Fatiha Djafri, Affaf Tabti

This study examined adsorption of anionic dye on four zeolitic materials incorporated (VS-1, CuZSM-5) and not incorporated into metals (S-1, ZSM-5). The adsorption of the bromothymol blue (BTB) dye on the four adsorbents was analysed using isotherm models Langmuir, Freundlich, and Temkin. Two…, U ovoj je studiji ispitivana adsorpcija anionskih bojila na četiri zeolitska materijala inkorporirana (VS-1, CuZSM-5) i neinkorporirana (S-1, ZSM-5) u metale. Adsorpcija indikatora bromtimol modro (BTB) na četiri adsorbenta analizirana je izotermnim modelima Langmuir, Freundlich i Temkin. Također…

Immobilization of atrazine on gold, a first step towards the elaboration of an indirect immunosensor, characterised by XPS and FT-IRRAS

Michèle Salmain, Natahlie Fischer-Durand, Céline Roche, Claire-Marie Pradier

As part of our long-term goal to design a novel type of immunosensor based on IR transduction, we devised two strategies to immobilize derivatives of the herbicide atrazine on the surface of planar gold substrates. Both strategies take advantage of the well-known formation of self-assembled…

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,…

An Anthropocene-Framed Transdisciplinary Dialog at the Chemistry-Energy Nexus

Mathieu S Prévot, Valeria Finelli, Xavier Carrier, Gabriele Deplano, Margherita Cavallo, Elsje Alessandra Quadrelli, Juliette Michel, Marie-Hélène Pietraru, Clément Camp, Giulia Forghieri, Anna Gagliardi, Sebastian Seidel, Antoine Missemer, Bertrand Reuillard, Barbara Centrella, Silvia Bordiga, María Grace Salamanca González, Vincent Artero, Keanu V. A. Birkelbach, Niklas von Wolff

At the energy-chemistry nexus, key molecules include carbon dioxide (CO2), hydrogen (H2), methane (CH4), and ammonia (NH3). The position of these four molecules and that of the more general family of synthetic macromolecular polymer blends (found in plastics) were cross-analyzed with the planetary…

Carbon Dioxide Reforming of Methane over Nickel-Supported Zeolites: A Screening Study

Carmen Bacariza, Leila Karam, Nissrine El Hassan, José Lopes, Carlos Henriques

As the utilization of zeolites has become more frequent in the dry reforming of methane (DRM) reaction, more systematic studies are required to evaluate properly the influence of zeolites’ composition and framework type on the performance. Therefore, in this work, a step-by-step study was performed…

The influence of C1 and C2 organic reducing agents on catalytic properties of Co(II)-single site BEA zeolite in SCR of NO

Janusz Janas, Wojciech Rojek, Stanislaw Dzwigaj

CoSiBEA zeolite with 0.9 wt.% Co is prepared in acidic (pH = 2.5) condition by a two-step postsynthesis method which allows to incorporate cobalt into framework zeolite as isolated tetrahedral Co(II) species, as evidenced by XRD and diffuse reflectance UV-vis. As obtained Co(II)-single site zeolite…
