Thermal and mechanical performances of bamboo strip

Materials Research Express, 2021
Bamboo strips extracted from Phyllostachys viridiglaucescens, grown in Europe, were analysed to assess their thermal and mechanical properties for composites application. Thermal stability of the European bamboo was studied by Thermogravimetric Analysis (

Modèle de prédiction de la dégradation des matériaux polymères en milieu réel

Sciences, Eaux & Territoires, 2000
Le développement de polymères biodégradables, pour l'emballage et les produits d'usage courant a pris un intérêt considérable. Cependant, dire qu'un matériau est biodégradable nécessite d'évaluer son taux de biodégradabilité. L'objectif de ce travail est

Switchable supramolecular helices for asymmetric stereodivergent catalysis

Nature Communications
Despite recent developments on the design of dynamic catalysts, none of them have been exploited for the in-situ control of multiple stereogenic centers in a single molecular scaffold.

Dynamic mechanical behaviour of polyamide 11/Barium titanate ferroelectric composites [PDF]

, 2010
Dynamic mechanical analysis and tensile test have been used to characterize the mechanical behaviour of hybrid composites. Barium titanate (BaTiO3) is the submicron filler and polyamide 11 (PA 11) the matrix.

Self-assembly in solution of a reversible comb-shaped supramolecular polymer [PDF]

, 2010
We report a single step synthesis of a polyisobutene with a bis-urea moiety in the middle of the chain. In low polarity solvents, this polymer self-assembles by hydrogen bonding to form a combshaped polymer with a central hydrogen bonded backbone and ...

Synthesis of mesogenic phthalocyanine-C60 donor–acceptor dyads designed for molecular heterojunction photovoltaic devices

Beilstein Journal of Organic Chemistry, 2009
A series of phthalocyanine-C60 dyads 2a–d was synthesized. Key steps in their synthesis are preparation of the low symmetry phthalocyanine intermediate by the statistical condensation of two phthalonitriles, and the final esterification of the fullerene ...
