Heat‐Resistant Copper Alloys for Extreme Thermal Environments: Mechanisms, Architectures, and Design Strategies

cMat, Volume 3, Issue 2, June 2026.
ABSTRACT Copper (Cu) and copper‐based alloys are indispensable in high‐heat‐flux systems, such as aerospace propulsion, fusion reactors, and advanced power electronics, due to their high thermal conductivity and good manufacturability. However, extreme service conditions increasingly demand not only high thermal conductivity but also elevated ...

Microstructural, Magnetic, and Tribological Optimization of Nano‐ZrO2 Reinforced Magnesium Matrix Composites Fabricated via Powder Metallurgy

Engineering Reports, Volume 8, Issue 6, June 2026.
Magnesium–ZrO2 nanocomposites fabricated via powder metallurgy exhibited enhanced density, magnetic saturation (up to 14 emu/g), and wear resistance. Uniform nanoparticle dispersion improved bonding and reduced delamination, demonstrating strong potential for lightweight, multifunctional applications in aerospace and automotive engineering.

The effect of compliance assistance on pollution discharges and violations of environmental regulations

Journal of Policy Analysis and Management, Volume 45, Issue 3, Summer 2026.
Abstract Researchers and policymakers assert competing behavioral models of polluters. One model portrays polluters as best approximated by the perfectly informed, rational actor from economics textbooks. Another model portrays polluters, particularly small and medium facilities, as imperfectly informed, cognitively bounded, pro‐social actors.

The precipitation behavior of MgZn2 and Mg4Zn7 phase in Mg-6Zn (wt.%) alloy during equal-channel angular pressing

Journal of Magnesium and Alloys, 2017
As-extruded Mg-6Zn (wt.%) Alloy was subjected to severe plastic deformation (SPD) by the equal-channel angular pressing(ECAP) at 160 oC. The results of tensile tests at room temperature showed that two passes ECAP resulted in a remarkable improvement of ...

Bioinspired Hierarchical Architecture with Water Transport Channels for Strong Adhesion at the Sweating Interface

Advanced Science, Volume 13, Issue 28, 18 May 2026.
To address adhesion failure in sweaty epidermal electronics, this study proposes a cross‐species, multi‐scale biomimetic interface. By modeling staged wet adhesion, it integrates self‐regulating liquid bridges with directional drainage. This design ensures stable, high‐performance flexible sensing in complex physiological environments, offering a ...
