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.

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,…

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…
