Multiscale Design of Anion Exchange Membrane‐Based Seawater Electrolysis for Sustainable Hydrogen Production

open access: yesAdvanced Energy Materials, EarlyView.
Direct seawater electrolysis using anion exchange membranes is emerging as a promising route for sustainable hydrogen production. This review summarizes multiscale design strategies from seawater chemistry and OER–ClER selectivity to catalysts, membranes, MEAs, cells, stacks, and system integration, providing a roadmap toward selective, durable, and ...

Molecular Engineering of a Mixed‐Spacer System Toward High‐Performance Polycarbazole Anion‐Exchange Membranes

open access: yesAngewandte Chemie, EarlyView.
Mixed‐spacer polycarbazole membranes balance conductivity, swelling, and stability by tuning hydration and ionic connectivity. The optimized membrane reaches 184 mS cm−1 hydroxide conductivity and 2.51 W cm−2 peak power density, offering a promising strategy for high‐performance ether‐free AEMs.

Membranes fibres creuses innovantes: conception, elaboration, applications [PDF]

open access: yes, 2012
Cette HDR est longue, 105 pages pour le texte seul. J'ai voulu écrire un texte qui, d'une part, reprend mes principaux travaux alors que j'ai soutenu ma thèse il y a 17 ans et qui, d'autre part, fait le lien entre les diverses thèses consacrées par ...

Joule self‐heating enabled oxygen transport and coupled methane reactions in a La0.6Sr0.4Co0.2Fe0.8O3‐δ hollow fiber membrane reactor

open access: yesAIChE Journal, EarlyView.
Abstract Mixed‐conducting ceramic hollow fiber membranes are a versatile platform for oxygen separation, value‐added chemical production, and oxy‐combustion. Because oxygen permeation is thermally activated, these systems typically rely on bulky, energy‐intensive furnaces that suffer from low efficiency and large thermal inertia.

Sulfur source-mediated transcriptional regulation of the rhlABC genes involved in biosurfactants production by Pseudomonas sp. strain AK6U

open access: yesFrontiers in Microbiology, 2014
Despite the nutritional significance of sulfur, its influence on biosurfactants production has not been sufficiently studied. We investigated the expression of key biosurfactants production genes, rhlABC, in cultures of Pseudomonas sp.

De Novo Design and Structural Optimization of Mn(salen)‐Based Artificial Metalloenzymes for Asymmetric Sulfoxidation

open access: yesAngewandte Chemie, EarlyView.
We report the computational design of de novo proteins that bind Mn(salen)‐based complexes (L1) using Rosetta FastDesign and verified by AlphaFold2. After screening, the catalytic activity for the promising design (dnMSBP) toward enantioselective sulfoxidation of thioanisole was optimized based on its crystal structure. With 10 different substrates, we

Sulfination of Unactivated Allylic Alcohols via Sulfinate–Sulfone Rearrangement

open access: yes, 2023
A dehydrative cross-coupling of unactivated allylic alcohols with sulfinic acids was achieved under catalyst-free conditions. This reaction proceeded via allyl sulfination and concomitant allyl sulfinate–sulfone rearrangement.
