Bioinspired Shape‐Memory Hook Fasteners With Programmable Interlocking and Silent Release

open access: yesAdvanced Engineering Materials, EarlyView.
Bioinspired hook fasteners made from epoxy shape‐memory polymers are shown to switch between strong, secure attachment and gentle, silent release when heated. By combining programmable geometry and material response, these adaptive fasteners outperform commercial systems in strength and noise control, enabling new solutions for robotics, medical ...

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

open access: yesAdvanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...

LA GUERRE DANS TROIS NOUVELLES DE MARCEL AYMÉ : LA CARTE, LE DÉCRET, LÉGENDE POLDÈVE [PDF]

open access: yesStudii si Cercetari Filologice: Seria Limbi Romanice, 2017
Pourquoi ces nouvelles ? Elles ont été publiées en pré-originale dans des journaux de droite ou collaborationnistes - le prétexte pour certains de mettre très vite l’étiquette de collaborateur à leur auteur.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

open access: yesAdvanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

AUTOMNE - UN POÈME APOLLINAIRIEN DE LA DISSOLUTION DES CORPS [PDF]

open access: yesStudii si Cercetari Filologice: Seria Limbi Romanice, 2012
Le poème apollinairien Automne, d’une simplicité qui frise la banalité, s’avère être une création très riche en suggestions, construisant un univers concret, palpable, physique, situé dans un espace-temps relativement déterminé, qui se commue petit à ...

Meta‐Rod Mechanical Metamaterials With Programmable Reconfiguration

open access: yesAdvanced Functional Materials, EarlyView.
Existing mechanical metamaterials achieve programmable large deformations in planar square or cubic configurations, restricted by required complex boundary conditions. This research proposes a 1D metamaterial, Meta‐rod, with linear, bending, twisting, area, and volume deformation modes.

Optically-detected spin-echo method for relaxation times measurements in a Rb atomic vapor

open access: yesNew Journal of Physics, 2017
We introduce and demonstrate an experimental method, optically-detected spin-echo (ODSE), to measure ground-state relaxation times of a rubidium (Rb) atomic vapor held in a glass cell with buffer-gas.
