Fluorinated Deep Eutectic Gel Electrolytes with Simultaneously Enhanced Mechanical Strength and Ionic Conductivity for Solid‐State Lithium Metal Batteries

open access: yesAdvanced Materials, EarlyView.
The synergistic integration of rigid polyacrylamide (PAM) and flexible poly(N,N‐dimethylacrylamide) (PDMA) phases offers exceptional toughness to suppress lithium dendrites, simultaneously enhancing mechanical strength and ionic conductivity. ABSTRACT Gel polymer electrolytes for lithium‐metal batteries face an inherent trade‐off between mechanical ...

Escaping the Scaling Relationships in Oxygen Reduction Catalysis: Implications for PEM Fuel Cells

open access: yesAdvanced Materials, EarlyView.
Escaping the scaling relationships of the oxygen reduction reaction is vital for hydrogen fuel cells. This outlook examines how interfacial heterogeneity, spanning the subsurface lattice, chemisorption layer, and near‐interface solvation volume, mechanistically decouples intermediate binding energetics.

High‐Performance Bio‐Glue From the Berries of a Parasitic Plant

open access: yesAdvanced Materials, EarlyView.
We report a fully bio‐based adhesive derived primarily from a (poly)saccharide extract obtained from the berries of the hemi‐parasitic plant mistletoe (Viscum album), supplemented with tannic and malic acid without any further chemical functionalization.

The social dramaturgy of forced disappearance in Argentina : ways to resist impunity [PDF]

open access: yes, 2010
Entre 1976 et 1983, la dictature militaire argentine orchestre la disparition d’environ trente mille personnes. Son but n’est pas seulement la mort, mais l’empêchement de toute forme de différence et de toute forme de résistance chez les vivants. Dans un

Establishing Atomic Coherence in Twisted Oxide Membranes Containing Volatile Elements

open access: yesAdvanced Materials, EarlyView.
Twisted oxide membranes containing volatile elements often suffer from amorphous interfacial dead layers that suppress coupling. An oxygen‐annealing strategy establishes atomically coherent and chemically bonded interfaces in twisted NaNbO3 membranes, enabling coherent oxide moiré architectures in volatile‐element‐containing systems.
