Évolution des stocks de carbone en fonction des trajectoires de gestion en zone humide

Sciences, Eaux & Territoires, 2018
Plans de gestion et études d'impact devraient dorénavant inclure les services écosystémiques (SE). Face au changement climatique, la régulation du climat global par le stockage de carbone par les écosystèmes est un SE au cœur des préoccupations. C'est un

Decoupling Light Absorption From Photocatalytic Reactivity in TiO2 via Defect and Interfacial Engineering

Advanced Functional Materials, EarlyView.
A hybrid photoprotective material integrates N‐doped TiO2 with a metal‐phenolic network (MPN) to achieve broad‐spectrum attenuation and robust reactive oxygen species (ROS) suppression. Nitrogen doping extends attenuation into the UVA/high energy visible light (HEV) regions and facilitates fast charge recombination to inhibit ROS formation.

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

Advanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...
