Nanoengineered Binetworks in Multifunctional Anionic Block Polymer Mesoblends for Improved Mechanical Properties

open access: yesAdvanced Functional Materials, EarlyView.
Mesoblends consist of a nanostructured polymer into which a second polymer is imbibed with a selective solvent. In this work, a solvent‐templatable pentablock terpolymer possessing a sulfonated midblock is modified with a hydrophilic polymer that is photocrosslinked in situ, yielding a hierarchical binetwork.

Radiations UV et composés photoprotecteurs (étude comparée chez deux végétaux marins, l'algue brune Pelvetia canaliculata et l'angiosperme Salicornia ramosissima)

open access: yes, 2011
Les fortes intensités lumineuses, et notamment l augmentation actuelle de l intensité des radiations UV-B due à l amincissement de la couche d ozone, peuvent être des facteurs stressants majeurs pour la plupart des organismes phototrophes peuplant les ...

UVA, UVB and UVC Light Enhances the Biosynthesis of Phenolic Antioxidants in Fresh-Cut Carrot through a Synergistic Effect with Wounding

open access: yesMolecules, 2017
Previously, we found that phenolic content and antioxidant capacity (AOX) in carrots increased with wounding intensity. It was also reported that UV radiation may trigger the phenylpropanoid metabolism in plant tissues.

Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.

Magnetic‐Field Control of Surface States in CoFe2O4 Thin Films for Nitrate Electroreduction to Ammonia

open access: yesAdvanced Functional Materials, EarlyView.
Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...

Effects of UV-C radiations on the response of romaine lettuce to biotic and abiotic stresses

open access: yes, 2014
Appliqués à forte dose, les rayonnements UV-C sont délétères, alors que administrés à faibles doses, ces memes rayonnements stimulent des réponses bénéfiques. Ce phénomène est connu sous le nom d’hormesis et la dose bénéfique est qualifiée d’hormique.
