Unravelling surface changes on Cu-Ni alloy upon immersion in aqueous media simulating catalytic activity of aerobic biofilms

Nesrine Aissaoui, Irma Liascukiene, Michel Genet, Christine Dupont-Gillain, Karim El Kirat, Caroline Richard, Jessem Landoulsi

Cu-Ni alloys are extensively used in contact with natural waters and are impacted by microbial activities of biofilms. The mechanisms by which surface changes occur upon immersion remain not well understood. Herein, an aerobic microbial activity of natural biofilms is mimicked by the enzymatic…

New Insights into Radical Mechanisms in Natural Drying Oils: Paint Binders as Reactors for Nanoparticle Formation

Laurence de Viguerie, Yongjie Yang, Fabrice Morlet-Savary, Jacques Lalevée, Sandra Casale, Christine Péchoux, Maguy Jaber, Gilles Patriarche

Understanding radical processes in drying oils is essential for both heritage science and materials chemistry, as these reactions govern film formation and long-term stability in historical paintings. In this study, we investigate radical mechanisms in linseed oil, a traditional paint binder. Gold…

The Influence of TiO2 Nanoparticles Morphologies on the Performance of Lithium-Ion Batteries

Wenpo Luo, Juliette Blanchard, Yanpeng Xue, Abdelhafed Taleb

Anode materials based on the TiO2 nanoparticles of different morphologies were prepared using the hydrothermal method and characterized by various techniques, such as X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), and N2 absorption. The TiO2 nanoparticles prepared…

Tracking element-specific dissolution during pitting corrosion: an operando ICP-AES–electrochemical study of the CoCrFeMnNi Cantor alloy

Yaojun Hou, Oumaïma Gharbi, Chenyang Xie, Divino Salvador Ramírez Rico, Fan Sun, Mireille Turmine, Kevin Ogle, Vincent Vivier

In this work, a flow-through electrochemical–ICP-AES platform for operando monitoring of pitting corrosion on the CoCrFeMnNi high-entropy alloy is introduced. This setup combines localized chloride injection, potentiostatic control, and online, element-resolved dissolution analysis, thereby…

Gold Colloid-Nanostructured Surfaces for Enhanced Piezoelectric Immunosensing of Staphylococcal Enterotoxin A

Maroua Ben Haddada, Michèle Salmain, Souhir Boujday

We describe the use of gold nanoparticles (AuNP) as a nanostructuring agent on quartz crystal sensor chips to engineer staphylococcal enterotoxin A (SEA) piezoelectric biosensors with amplified response. AuNPs were assembled on gold- or silicon-coated quartz crystal sensor chips by a wet chemistry…

Glutamic Acid Adsorption and Transformations on Silica

Meryem Bouchoucha, Maguy Jaber, Thomas Onfroy, Jean-François Lambert, Xue Baiyi

We report here on the adsorption and deposition of l-glutamic acid (Glu) on an amorphous silica and its subsequent thermal transformations. When adsorbed from aqueous solutions, Glu only has a low affinity for the silica surface but at high concentrations the adsorbed molecules serve as nuclei for…

Highly Conductive Tungsten Suboxide Nanotubes

Cécile Huez, Maxime Berthe, Florence Volatron, Jean-Michel Guigner, Dalil Brouri, Lise-Marie Chamoreau, Benoît Baptiste, Dominique Vuillaume, Anna Proust

We demonstrate a high electron conductivity (> 10^2 S/cm and up to 10^3 S/cm) of tungsten suboxide W18O(52.4-52.9)(or equivalently WO(2.91-2.94)) nanotubes (2 to 3 nm in diameter, ca. micrometer long). The conductivity is measured in the temperature range 120 to 300K by a four probe scanning…

Stability and degradation of PEO₂₀PPO₇₀PEO₂₀ triblock copolymers in mesostructured silica

Brindusa Dragoi, Guillaume Laurent, Sandra Casale, Taissire Benamor, Bénédicte Lebeau, Cédric Boissière, François Ribot, Mohamed Selmane, Patrick Schmidt, David Kreher, Anne Davidson

Organic−inorganic hybrid mesostructured silicas are prepared, without stirring (at pH = 0.0) and with stirring (at pH = 0.6) to obtain isolated and gyroidal-like attached silica grains with incorporated triblock P123 poly (ethylene oxide)-poly (propylene oxide)–poly (ethylene oxide) copolymers.…
