No Place to Hide? Regional Resilience and Vulnerability to Global Catastrophic Risk

Global Challenges, Volume 10, Issue 8, August 2026.
No location on Earth withstands every global catastrophe. This review maps the geographic, institutional and infrastructural factors shaping resilience to nuclear, volcanic and impact winters, infrastructure loss and pandemics. Geographic isolation, food self‐sufficiency, strong governance and decentralization improve resilience across scenarios ...

Experimental and Modeling Investigation of Seawater Hydrolysis Effects on Aramid Fiber Rupture Behavior

Journal of Polymer Science, Volume 64, Issue 15, Page 3289-3309, 1 August 2026.
Hydrolytic aging in seawater produces markedly different mechanical responses among commercial Aramid fibers. While some fibers exhibit progressive degradation, others maintain stable or even improved tensile behavior. Experimental yarn‐scale testing combined with mathematical degradation modeling and Arrhenius‐based lifetime prediction provides new ...

The Evolution of Semiconductor Devices: From Transistors to Quantum and Neuromorphic Computing

physica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 8, August 2026.
This review presents the evolution of semiconductor devices from BJTs to fin field‐effect transistors (FinFETs), nanowire, and carbon nanotube transistors. It highlights emerging materials, including SiC and GaN, and examines neuromorphic and quantum computing, industry applications, performance benchmarks, challenges, and future directions.

Abnormal Phase Transition Mechanism in the CoCrAlY Bond Coat Revealed by In Situ and Ex Situ Experiments

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT In Co‐based alloys, the γ phase is normally stable at high temperatures and the ε phase at low temperatures, and there is a martensitic transition on cooling to ∼417°C. In the γ/β dual‐phase CoCrAlY bond coat of turbine blade thermal barrier coating systems, we observed the opposite: γ remained stable at room temperature, yet it underwent a γ →
