Controlled Interfacial Stress Platform for Electrochemical‐Mechanical Coupling Measurements

open access: yesAdvanced Energy Materials, EarlyView.
Understanding electrochemical‐mechanical coupling in solid‐state batteries is vital for predicting their performance, degradation, and safety. Conventional screw‐jig platforms provide data but lack insights into stress effects on individual couplings.

Tellurophene‐Induced Triplet–Singlet Spin‐Flip Acceleration: An Advanced Design for Narrowband Organoboron Emitters with Fast Reverse Intersystem Crossing

open access: yesAngewandte Chemie, EarlyView.
Linking an auxiliary dibenzo[b,d]tellurophene unit markedly accelerates exciton spin conversion in multi‐resonance‐type thermally activated delayed fluorescence emitters. Owing to the heavy‐atom effect of tellurium, the corresponding OLEDs retain remarkably high external electroluminescence quantum efficiencies exceeding 25% even at an exceptionally ...

La terrasse du Plan de Dieu : contraintes, occupation du sol, aménagement

open access: yes, 1995
The Plan de Dieu is a dry terrace of the Riss and Würm, situated on the left bank of the Rhône, between the rivers Ouvèze and Aigues, which has many rich agricultural soils at its centre. The exchange of energy and matter between the terrace and its surrounding environment allows us to define its agronomical characteristics.Human occupation during ...

Compositional Tuning and Surface Restructuring Synergistically Enhance Perovskite Ferrite Catalysts for Hydrogen Evolution in a Membrane‐Less Electrolyzer

open access: yesAdvanced Energy Materials, EarlyView.
In this work, a self‐restructuring Fe‐based perovskite catalyst is developed, leveraging in situ amorphization to achieve a “self‐improving” behavior for hydrogen evolution. When integrated into a custom‐built membrane‐less electrolyzer, the system demonstrates a record‐breaking 1000 h stability, providing a robust and practical pathway for the ...

Apport de la télédétection spatiale à la gestion intégrée du lagon de Saint-Gilles / La Saline à l'île de La Réunion : Un exemple d'application : cartographie et suivi des zones susceptibles à l'érosion des sols, entre 1995 et 2002, par intégration des données spot [PDF]

open access: yes, 2003
Cette étude réalisée à l'île de La Réunion, s'inscrit dans le cadre du projet AGIL (Aide à la Gestion Intégrée des Littoraux) qui propose une approche innovante de la gestion côtière par l'utilisation des technologies spatiales d'observation de la Terre.

Beyond Imperfect Match: Silicon/Graphite Hybrid Anodes for High‐Energy–Density Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Silicon/graphite (Si/Gr) hybrid anodes are limited by Si's large volume change and mismatch with Gr. This review offers mechanistic insights into imperfectly matched Si/Gr hybrid anodes, elucidating heterogeneous lithiation behavior and interfacial failure pathways, and thereby informing the design of durable, high‐energy–density lithium‐ion batteries.

Light Stability of Laser‐Assisted Glass Encapsulated Perovskite Solar Cells under Different Atmospheres

open access: yesAdvanced Energy Materials, EarlyView.
This study presents a laser‐assisted glass‐frit encapsulation method for perovskite solar cells, comparing air‐, nitrogen‐, and CO2‐filled cavities. Results show that excluding oxygen and moisture significantly improves stability under illumination. The findings reveal the critical role of trapped gases in degradation, providing a pathway to durable ...
