Ultrahigh Strength with Suppressed Flow Instability at Liquid Helium Temperature via Coherent Nanoprecipitation in a Medium‐Entropy Alloy

open access: yesAdvanced Functional Materials, EarlyView.
It is demonstrated that severe lattice distortion and coherent nanoprecipitates overcome the strength–ductility dilemma and mitigate discontinuous plastic flow (DPF) at 4.2 K. Such microstructural design enhances both thermal and athermal stress components, leading to exceptional mechanical performance.

Assessing the Impact of Catastrophic Electricity Loss on the Food Supply Chain

open access: yesInternational Journal of Disaster Risk Science
The food supply chain’s heavy reliance on electricity poses significant vulnerabilities in the event of prolonged and widespread power disruptions. This study introduces a system-dynamics model that integrates five critical infrastructures—electric grid,

Designing Thermally Compatible Template‐Coating Pairs Toward Dimensionally Stable 3D Porous Carbons with Tunable Density

open access: yesAdvanced Functional Materials, EarlyView.
3D porous carbons with tunable density are crucial for energy storage, separations, and load‐bearing applications; however, their fabrication is often constrained by shrinkage during pyrolysis. This study optimizes and demonstrates the versatility of a template–coating pair strategy, producing materials that largely retain their shape and hierarchical ...

Golden‐Ratio–Guided Aperiodic Architected Metamaterials with Simultaneously Enhanced Strength and Toughness

open access: yesAdvanced Functional Materials, EarlyView.
Guided by the golden ratio, a class of aperiodic architected metamaterials is introduced to address the intrinsic trade‐off between strength and toughness. By unifying local geometric heterogeneity with global order, the golden‐ratio‐guided aperiodic architecture promotes spatial delocalization of damage tolerence regions, leading to more tortuous ...

A Scalable, Durable, Fire‐Safe All‐Day Passive Radiative Cooling Coating for Sustainable Buildings

open access: yesAdvanced Functional Materials, EarlyView.
This study reports a scalable, durable coating that combines a fire‑retardant copolymer adhesive, hollow glass microspheres, and boron oxide to achieve passive radiative cooling with over 94% solar reflectance and >95% mid‑infrared emissivity. The coating maintains performance after UV and rain exposure and exhibits UL‑94 V‑0 fire resistance, enabling ...

Refugee-state distrust on the Thai-Burma border

open access: yesForced Migration Review, 2015
Distrust between refugees and their state of origin must be given due consideration in institutional approaches to repatriation of refugees, on the Thai-Burma border and in other refugee contexts worldwide.
