Reprogrammable Phase‐Transition Composites for Adaptive Dynamic Shape Morphing

Advanced Science, EarlyView.
This paper reports a bio‐inspired reprogrammable phase‐transition composites that uses the stiffness change induced by reversible solid‐liquid phase transition to program and regulate the material deformation actuated by reversible liquid‐vapor phase transition, thereby achieving adaptive dynamic deformation in a controllable manner, and enabling ...

Mitigating Thermal Runaway in Lithium Metal Batteries With Flame‐Retardant Magnesium Hydroxide Nanocomposite Gel Electrolytes

Advanced Energy Materials, EarlyView.
Lithium‐ion batteries are ubiquitous but pose significant safety risks especially with high‐energy‐density electrode materials. This study reports a nanocomposite gel electrolyte (NGE) with a flame‐retardant magnesium hydroxide (MH) matrix, which offers robust mechanical properties, high ionic conductivity, and enhanced thermal safety.

The Power of Unity: Collective Action and Smallholder Agricultural Performance in West Africa

Agribusiness, EarlyView.
ABSTRACT We analyze the impact of collective action through farmer‐based organizations (FBOs) on smallholders' farm performance and income inequality in Ghana, Benin, The Gambia, and Mali. We find that FBO membership increases cereal yield in Ghana and The Gambia, legume yield in Mali, ruminant numbers in Benin and The Gambia, and total farm income in ...

Bayesian Optimization Guiding the Experimental Mapping of the Pareto Front of Mechanical and Flame‐Retardant Properties in Polyamide Nanocomposites

Advanced Intelligent Discovery, EarlyView.
Bayesian optimization enabled the design of PA56 system with just 8 wt% additives, achieving limiting oxygen index 30.5%, tensile strength 80.9 MPa, and UL‐94 V‐0 rating. Without prior knowledge, the algorithm uncovered synergistic effects between aluminum diethyl‐phosphinate and nanoclay.
