Binding and 2D organization of arginine on Cu(1 1 0)

Roberta Totani, Christophe Méthivier, Dominique Costa, Théo Jaffrelot Inizan, Claire-Marie Pradier, Vincent Humblot

In this work we present a detailed surface science characterization of L-arginine adsorption on the Cu(1 1 0) surface in a submonolayer regime. Arginine (ARG) is one of the main components of the tripeptide RGD (arginine-glycine-aspartic acid) commonly used as a linker/binder when engineering…

Assessing the potential of xNi-yMg-Al2O3 catalysts prepared by EISA-one-pot synthesis towards CO2 methanation: An overall study

Leila Karam, M. Carmen Bacariza, José David Lopes, Carlos Henriques, Pascale Massiani, Nissrine El Hassan

Mesoporous xNi-yMg-Al2O3 catalysts prepared by combined evaporation induced self-assembly (EISA) and one-pot techniques were tested in CO2 methanation reaction. All calcined/reduced materials were characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD), N2 physisorption,…

Bimetallic Fe-Ni/SiO2 catalysts for furfural hydrogenation: Identification of the interplay between Fe and Ni during deposition-precipitation and thermal treatments

Dichao Shi, Qifeng Yang, Christi Peterson, Anne-Félicie Lamic-Humblot, Jean-Sébastien Girardon, Anne Griboval-Constant, Lorenzo Stievano, Moulay Tahar Sougrati, Valérie Briois, Paul A.J. Bagot, Robert Wojcieszak, Sébastien Paul, Eric Marceau

Supported Fe-Ni catalysts have been reported for their activity and selectivity in the hydrogenation of unsaturated organic molecules. However, the control of the size and composition of the bimetallic nanoparticles remains a bottleneck when oxide-supported catalysts are prepared by impregnation,…

2D Monolayer of 1T' Phase of Alloyed WSSe from Colloidal Synthesis

Ashkan Shahmanesh, Davide Romanin, Corentin Dabard, Sang-Soo Chee, Charlie Gréboval, Christophe Methivier, Mathieu G Silly, Julien Chaste, Matthieu Bugnet, Debora Pierucci, Abdelkarim Ouerghi, Matteo Calandra, Emmanuel Lhuillier, Benoit Mahler

We explore the colloidal growth of monolayers of WSSe alloy in their 1T' phase with various Se content. We develop a synthetic procedure leading to reduced aggregation of the flakes. The presence of a narrow band-gap close to the top of the valence band has been evidenced combining…

On the Comprehensive Precipitation of Hydroxyapatites Unraveled by a Combined Kinetic–Thermodynamic Approach

Corentin Reynaud, Cyril Thomas, Guylène Costentin

The present study combines experimental and theoretical approaches to investigate the competitive precipitation of calcium phosphates (CaPs) in aqueous solution in order to understand and control both the structural and textural properties of the synthesized hydroxyapatites (HAps). Some of the…

The Mosaic Structure of Zeolite Crystals

Zhengxing Qin, Georgian Melinte, Jean-Pierre Gilson, Maguy Jaber, Krassimir Bozhilov, Philippe Boullay, Svetlana Mintova, Ovidiu Ersen, Valentin Valtchev

Zeolites are widely used in many commercial processes, mostly as catalysts or adsorbents. Understanding their intimate structure at the nanoscale is the key to control their properties and design the best materials for their ever increasing uses. Herein, we report a new and controllable fluoride…

Microphysiological Glomerular Filtration Barriers: Current Insights, Innovations, and Future Applications

Manon Miran, Kieu Ngo, David Buob, Hanna Debiec, Pierre Ronco, Guillaume Perry

Chronic kidney disease (CKD) affects over 850 million individuals worldwide, often progressing to stages requiring dialysis or kidney transplants. Central to kidney function is the glomerular filtration barrier (GFB), which selectively filters waste while retaining essential proteins. Traditional…

A fullerene helical peptide: synthesis, characterization and formation of self-assembled monolayers on gold surfaces

Houssein Nasrallah, Jad Rabah, Van Bui-Thi-Tuyet, Krystyna Baczko, Hélène Fensterbank, Flavien Bourdreux, Anne-Marie Goncalves, Valérie Declerck, Souhir Boujday, Vincent Humblot, Karen Wright, Anne Vallée, Emmanuel Allard

The synthesis of a C60-peptide using "clickable" fullerene and peptide derivatives is described. The peptide is composed of a repeating sequence of -aminoisobutyric acid (Aib) and two L-Alanine (Ala) residues, promoting the formation of a helical conformation, which has been confirmed by…

Impregnation of .gamma.-Alumina with Ni(II) or Co(II) Ions at Neutral pH: Hydrotalcite-Type Coprecipitate Formation and Characterization

Jean-Baptiste d'Espinose de la Caillerie, Maggy Kermarec, Olivier Clause

The adsorption of Co(II) or Ni(II) ammine complexes from aqueous solutions onto y-alumina at neutral or near neutral pH (7 < pH < 8.2) and ambient temperature is investigated as a function of the ion concentration in the impregnating solutions, the contact and aging times, and the drying…
