Ionic Transport and Charge Distribution in Miniaturized Electrochemical Energy Storage Devices by Modeling Investigation

Yannick Dufil, Frederic Favier, Thierry Brousse, Christophe Lethien, Jean Le Bideau, Olivier Fontaine

Ions are at the core of the mechanism involved in electrochemical energy storage. However, it remains difficult to physically measure the local ionic transport inside a working device. Limiting factors in the local transport in miniaturized electrochemical energy storage (MEES), especially in 3D Li…

Adsorption-reduction of Cr(VI) onto unmodified and phytic acid-modified carob waste: Kinetic and isotherm modeling

Kenza Bouaouina, Alexandre Barras, Nacer Bezzi, Mohammed Amin, Sabine Szunerits, Rabah Boukherroub

Carob waste (CW) is an agro-biomass material abundant in nature with potential use for eco-friendly remediation. However, like many biomass-based adsorbents, it suffers from its low adsorption capacity for organic/inorganic pollutants. Therefore, modification using physical and/or chemical means is…

[Review] Lessons from neonatal β-cell epigenomic for diabetes prevention and treatment

Amar Abderrahmani, Cécile Jacovetti, Romano Regazzi

Pancreatic β-cell expansion and functional maturation during the birth-to-weaning period plays an essential role in the adaptation of plasma insulin levels to metabolic needs. These events are driven by epigenetic programs triggered by growth factors, hormones, and nutrients. These mechanisms…
