Bonjour à tous,

Le prochain stage pédagogique du GFP : « La Mécanique des Polymères Expliquée au Chimiste» aura lieu au CEMEF du 3 au 5 juin 2019.

Vous trouverez en Pj le programme détaillé.

A très bientôt,
Le comité d’organisation

Le développement de matériaux verts performants est une préoccupation majeure de notre société pour faire face à l’épuisement des ressources fossiles. Pour la première fois en France, des chercheurs de l’Institut de chimie et procédés pour l’énergie, l’environnement et la santé (CNRS/Université de Strasbourg), en partenariat avec l’Université de Technologie d’Eindhoven, ont synthétisé un vitrimère polyimine totalement biosourcé. Ils montrent les propriétés dynamiques de ce nouveau matériau dans un article de la revue Green Chemistry (RSC). lire plus…

Recyclable plastics that contain ring-shaped polymers may be a key to developing sustainable synthetic materials. Despite some promising advances, researchers said, a full understanding of how to processes ring polymers into practical materials remains elusive. In a new study, researchers identified a mechanism called « threading » that takes place when a polymer is stretched—a behavior not witnessed before. This new insight may lead to new processing methods for sustainable polymer materials. lire plus…

The olive oil industry treats olive pomace (OP)—the skins, pulp, seeds, and stems of olives after pressing—as waste. But this so-called lignocellulose matter is a highly accessible raw material. The current environmental climate favors bio-based materials, such as OP, as substitutes for oil-based materials. lire plus…

Researchers at Kanazawa University synthesized helical ladder polymers with a well-defined cyclic repeating unit and one-handed helical geometry, as they reported in the Journal of the American Chemical Society. lire plus…

A research team from the Department of Energy’s Oak Ridge and Lawrence Berkeley National Laboratories, the University of California – Berkeley, and the University of South Florida developed a material that selectively binds dissolved uranium with a low-cost polymer adsorbent. The results, published in Nature Communications, could help push past bottlenecks in the cost and efficiency of extracting uranium resources from oceans for sustainable energy production. lire plus…

Defects of the skull and facial bones can pose difficult challenges for plastic and reconstructive surgeons. A synthetic material called hyperelastic bone — readily produced by 3D-printing — could offer a powerful new tool for use in reconstructing skull defects. lire plus…

A team of scientists has created a bowl-shaped electrode with ‘hot edges’ which can efficiently convert carbon dioxide from gas into carbon based fuels and chemicals, helping combat the climate change threat posed by atmospheric carbon dioxide. lire plus…
