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…

Non-Hydroxyl Radical Species Production during Dark Air Oxidation of Alluvial Soils

Elora Bourbon, Frédéric Averseng, Pierre Le Pape, Thierry Allard, Fulvia Baratelli, Fabrice Alliot, Alexandre Gélabert, Valentine Rollot, Elodie Guigon, Jessica Brest, Sylvie Nélieu, Guillaume Morin

Natural environments subjected to hydrologically-driven redox fluctuations are regarded as propitious to contaminant degradation since they favor cyclic oxygenation of Fe(II)-minerals that produces oxidizing reactive species, such as the hydroxyl radical, OH • . However, the identity of these…

Gold surface nanostructuring for separation and sensing of biomolecules, Nanostructuration des surfaces d'or pour la séparation et la détection de biomolécules

Erin Bedford

Detecting biomolecules in physiological environments is critical to health care and environmental monitoring. In this work, we study and use gold surfaces for biomolecule detection while incorporating nanoscale components—specifically, self-assembled monolayers (SAMs) of alkanethiols and gold…, La détection de molécules biologiques dans les environnements physiologiques est essentielle aux soins de santé et la surveillance de l'environnement. Dans ces travaux de thèse, nous étudions et utilisons des surfaces d'or pour la détection de biomolécules, avec l'inclusion de…

Equilibrium and dynamics of single-peptide binding to aluminum oxides: Emphasizing the role of local surface charge and hydrophobicity

Joanne Lê-Chesnais, Christophe Méthivier, Daniela Rodriguez, Christophe Humbert, Jean-François Lambert, Jessem Landoulsi

Understanding the interactions between biomolecules and mineral surfaces is a fundamental challenge at the crossroads of colloid science, surface chemistry, and molecular biophysics. While peptides and amino acids are known to bind a variety of metal oxides, our understanding remains limited…

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…

Ultra-Compact Electrical Double Layers at TiO₂ (110) Electrified Interfaces

Immad Nadeem, Christopher Penschke, Ji Chen, Xavier Torrelles, Axel Wilson, Hadeel Hussain, Gregory Cabailh, Oier Bikondoa, Jameel Imran, Christopher Nicklin, Robert Lindsay, Jörg Zegenhagen, Matthew Blunt, Angelos Michaelides, Geoff Thornton

Metal-oxide aqueous interfaces are important in areas as varied as photocatalysis and mineral reforming. Crucial to the chemistry at these interfaces is the structure of the electrical double layer formed when anions or cations compensate for the charge arising from adsorbed H<sup>+</sup…

Optimization of Synthesis Conditions of Ni/SBA-15 Catalysts: Confined Nanoparticles and Improved Stability in Dry Reforming of Methane

Nissrine El Hassan, Marie-Nour Kaydouh, Nissrine El, Anne Davidson, Pascale Massiani

Despite its economic and environmental advantages, the dry reforming of methane using supported Ni-based catalysts remains challenging due to problems of metal particle sintering and carbon deposition, which lead to loss in catalytic activity. In this study, different silica supports, containing 5…

Loop-stabilized BAB triblock copolymer morphologies by PISA in water

Pauline Biais, Patricia Beaunier, François Stoffelbach, Jutta Rieger

A straightforward strategy to synthesize in water, loop-stabilized particles via PISA is developed. These particular structures can in theory be obtained through the synthesis of amphiphilic BAB triblock copolymers, starting from a hydrophilic middle block A, which is chain extended in an aqueous…

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

Aïcha Gharbi, Thibaut Legigan, Vincent Humblot, Sébastien Papot, 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…
