Molecularly Dissipative Liquid Crystal Elastomer Foams for Impact and Vibration Attenuation

Advanced Functional Materials, EarlyView.
Liquid crystal elastomer foams integrate cellular deformation with mesogen reorientation to create a dual‐scale energy dissipation mechanism. Progressive pore collapse absorbs mechanical loads, while stress‐induced mesogen reorientation provides additional damping, resulting in reduced impact transmission and broadband suppression of vibrational ...

Oxygen Evolution Electrocatalysts with Trinuclear, Mixed‐Valence Iron Motifs on Electronically Aligned Carbon Dots

Advanced Functional Materials, EarlyView.
Trinuclear iron oxo‐bridged catalytic ensembles stabilized by aspartic‐acid‐derived carbon dots provide an effective platform for alkaline oxygen evolution. Mixed‐valence charge balancing, inner‐sphere charge transport, and work‐function alignment within the N/O‐rich carbon framework promote cooperative Fe‐site chemistry and efficient OER ...

Passive flow control around a semi-circular cylinder using porous coatings [PDF]

, 2014
International audienceIn this paper, the passive control of flow past a semi-circular cylinder is investigated. This control is achieved by adding a porous medium between the solid obstacle and the incompressible fluid in order to reduce drag forces and ...

Neuromorphic Devices for Extreme Environments: State‐Variable Reliability and Stabilization Strategies

Advanced Functional Materials, EarlyView.
Neuromorphic devices for extreme environments are interpreted through the physical states that store and process information. Radiation, temperature extremes, and vacuum can perturb vacancies, filaments, trapped charges, polarization, interfaces, and readout signals.
