Electron conductive self-assembled hybrid low-molecular weight glycolipid-nanosilver gels

Korin Gasia Ozkaya, Othmane Darouich, Hynd Remita, Isabelle Lampre, Lionel Porcar, Alain Carvalho, M. Schmutz, Sandra Casale, Christel Laberty-Robert, Niki Baccile

Low-molecular weight (LMW) hydrogels are gaining interest over macromolecular gels due to their reversible, dynamic and stimuli-responsive nature. They are potentially interesting functional materials for advanced applications such as catalysis, nanoelectronics or regenerative medicine. One common…

Brake wear (nano)particle characterization and toxicity on airway epithelial cells in vitro

Chloé Puisney, Evdokia K Oikonomou, Sophie Nowak, Alexandre Chevillot, Sandra Casale, Armelle Baeza-Squiban, Jean-François Berret

Particulate air pollution results from different sources, among which those related to road traffic have a significant impact on human health. Combustion-derived particles emitted by thermal engines have been incriminated and are now better controlled. In contrast, non-exhaust emission sources…

An expeditious synthesis of early transition metal carbide nanoparticles on graphitic carbons

Debora Ressnig, Simona Moldovan, Ovidiu Ersen, Patricia Beaunier, David Portehault, Clément Sanchez, Sophie Carenco

An expeditious synthesis of metal carbide nanoparticles onto various carbon supports is demonstrated. The procedure is versatile and readily yields TiC, VC, Mo2C and W2C nanoparticles on different types of carbons. The reaction is initiated at room temperature and proceeds within seconds. This…

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…

Nano-engineered hierarchical porous silicas for enhanced catalytic efficiency in the liquid phase

A. Zaki, M. Wastiaux, S. Casale, A. Mussi, J. Dhenin, C. Lancelot, Jean-Philippe Dacquin, P. Granger

By tailoring the pore properties (size, morphology and orientation) of hierarchical catalysts, we show experimentally the importance of active phase accessibility on catalytic efficiency.

Salt concentration and pH-dependent adsorption of two polypeptides on planar and divided alumina surfaces; in situ IR investigations.

Claire-Marie Pradier, Vincent Humblot, Lorenzo Stievano, Christophe Méthivier, Jean-François Lambert

The adsorption of proteins is the first process to take place when a solid is immersed in a biological fluid; though not yet thoroughly understood at a molecular level, this process is also known to be strongly influenced by the presence of salt in solution or by pH changes. In the present work,…

Clicked BODIPY‐Fullerene‐Peptide Assemblies: Studies of Electron Transfer Processes in Self‐Assembled Monolayers on Gold Surfaces

Jad Rabah, Houssein Nasrallah, Karen Wright, Isabelle Gérard, Hélène Fensterbank, Thi Tuyet Van Bui, Jérôme Marrot, Thu-Trang Tran, Anam Fatima, Minh-Huong Ha-Thi, Rachel Méallet, Gotard Burdzinski, Gilles Clavier, Souhir Boujday, Hubert Cachet, Catherine Debiemme-Chouvy, Emmanuel Maisonhaute, Anne Vallée, Emmanuel Allard

Two BODIPY‐C60‐peptide assemblies were synthesized by CuAAC reactions of BODIPY‐C60 dyads and a helical peptide functionalized with a terminal alkyne group and an azide group, respectively. The helical peptide within these assemblies was functionalized at its other end by a disulfide group,…

Impact of sorbitol addition on the structure and performance of silica-supported cobalt catalysts for Fischer-Tropsch synthesis

Hong Jingping, Eric Marceau, Andrei Y. Khodakov, Anne Griboval-Constant, Camille La Fontaine, Françoise Villain, Valérie Briois, P.A. Chernavskii

The paper focuses on the impact of sorbitol addition on the genesis of cobalt active phases in silica-supported catalysts and on their performance in Fischer-Tropsch synthesis. The catalysts were characterized by ex situ and in situ diffuse reflectance spectroscopy in the ultraviolet and visible…

Influence of the texturalproperties of porousaluminas on the reducibility of Ni/Al2O3 catalysts

Faiza Bentaleb, Eric Marceau

Temperature-programmed reduction (TPR) profiles recorded on calcined Ni/Al2O3 catalysts exhibiting the same Ni(II) surface density (3 Ni2+ nm−2) suggest that nickel speciation and reducibility are significantly influenced by the specific surface area and texturalproperties of aluminas, and by their…
