Robust β‐myrcene block copolymer elastomeric vitrimers

open access: yesPolymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Les matériaux archéologiques : applications et enjeux. L’exemple des « bronzes » durant la protohistoire européenne

open access: yesMosaïque, 2010
L’objectif est d’exposer l’histoire technique de certains objets archéologiques. Cela est indissociable de l’histoire sociale, car la production d’objets au sein d’une société suppose une organisation de celle‐ci et la mise en place d’un réseau ...

Impact of polymer aging on main‐chain poly(fullerene)s with halide chain‐ends for inverted perovskite solar cells

open access: yesPolymer International, EarlyView.
Subtle variations in halogen chemistry significantly affect the aging behavior of polymeric electron transport layers in inverted perovskite solar cells, underscoring the importance of precise chemical design for enhancing long‐term stability. Abstract As perovskite solar cells (PSCs) advance toward commercialization, the need for stable and easily ...

Modélisation, caractérisation et analyse du comportement dynamique des transferts de chaleur à travers la paroi en polyéthylène et en verre des serres agricoles

open access: yesRevue des Énergies Renouvelables, 2010
La serre tunnel agricole classique est largement répandue dans les pays méditerranéens malgré les insuffisances qu’elle présente, notamment la surchauffe pendant le jour et le refroidissement nocturne intense, qui parfois se traduit par l’inversion ...

Clinically‐Relevant Static Magnetic Field Induces Release of Encapsulated Molecules from Magnetoliposomes

open access: yesSmall, EarlyView.
This work demonstrates the feasibility of a molecule release from magnetoliposomes triggered by a constant 1.5 T magnetic field currently used in clinical settings. ABSTRACT Magnetoliposomes (MLs) are known for their great potential in drug release under an alternating current (AC) magnetic field (MF).

Photoluminescence Enhancement in Erbium Nanoparticles via Controlled Phase Transformation

open access: yesSmall, EarlyView.
Er‐NPs synthesized by PLAL were thermally treated from 200°C to 1000°C. Annealing at 600°C produced a full transition to the cubic Er2O3 phase and removed non‐radiative surface species. This led to a fivefold increase in PL. The results show how oxidation and phase purity control the optical performance of Er‐NPs.

Acid Resistant and Highly Silver Selective Membranes Based on Charged Nanoporous 2D‐Materials

open access: yesSmall, EarlyView.
In this work, new membranes based on charged & nanoporous nanosheets with unprecedented selectivity to silver versus a wide range of other metallic ions are reported. Furthermore, a demonstrated and lead specific intralamellar lead pathway is demonstrated. A potential applicability for ubiquitous silver in WEEE is validated.
