The ballistic resistance of auxetic re‐entrant honeycomb structures can be significantly improved through geometric tailoring and structural reinforcement. Vertical and horizontal stiffening ribs enhanced the ballistic performance, increasing the energy absorption efficiency by 119.45% and the projectile velocity reduction by 281.36%, ultimately ...

ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Israel's Post‐War Healthcare Obligations
ABSTRACT Since the beginning of the Israel–Hamas war in 2023, the healthcare infrastructure within Gaza has been dismantled. While international humanitarian law mandates distinction between lawful targets (combatants and military objectives) and non‐lawful targets (civilians and civilian objects), and acknowledging the inherent complexities of ...

Reconfiguration of Mercury's Exosphere During Strong Space Weather Events
Abstract Mercury is exposed to various space weathering processes, which alter the surface and cause emission of atoms and molecules into the exosphere. The exosphere thus allows remote insights into the surface composition and erosion processes, with the emission of refractory elements such as Ca and Mg typically being dominated by micrometeoroid ...

Textile‐waste Orlon is transformed into recycled PAN nanofiber interleaves for tougher and more damage‐resistant adhesive bondlines. ABSTRACT This study presents a sustainable toughening strategy for adhesively bonded CFRP joints by using electrospun polyacrylonitrile (PAN) nanofiber interleaves produced from virgin PAN (vPAN) and recycled PAN (rPAN ...

Abstract SO2 flux and gas composition were measured during the 2021 flank eruption of Pacaya Volcano (Guatemala). The SO2 flux, measured with Tropomi, gradually rose from ∼2 to ∼30 kg/s over a 5 month period before the eruption. Field UV camera data showed that >95% of the SO2 was emitted from the summit crater.
