Origami Metamaterials Based on Low‐Melting‐Point Alloy Phase Transition: Breaking the Trade‐Off Between Reusability and Energy Absorption Quality

Advanced Science, EarlyView.
This work presents an origami metamaterial that integrates a low‐melting‐point alloy skeleton into an elastomeric shell. It dissipates energy through the metal's plastic deformation and recovers through the solid–liquid phase transition of the alloy together with the hyperelasticity of the shell.

Properties of Lunar Dust and Their Migration on the Moon

Space: Science & Technology
Lunar dust, the finest fraction of lunar regolith, has undergone important space weathering on the Moon. It not only serves as a record of the evolution of the lunar surface environment and the modification of mineral properties, but also influences the ...

A 3D‐Printed SFE‐Graded Alloy Mitigates Cryogenic Discontinuous Plastic Flow and Hydrogen Embrittlement

Advanced Science, EarlyView.
A novel strategy features gradient composition and stacking fault energy‐tuned (CoCrMn)100‐2xFexNix fabricated via in situ alloying additive manufacturing. This design circumvents cryogenic discontinuous plastic flow and hydrogen embrittlement of metallic materials under quasi‐static loading and hydrogen‐rich environment relevant to lunar polar ...

Specificity of spaceport construction at a lunar base

Kosmičeskaâ tehnika. Raketnoe vooruženie
The 21st century started with changes in hopes and expectations for space exploration. Plans are being announced to move from researching and studying the solar system to colonizing it. The primary object of attention is the Earth’s natural satellite. A return to the Moon is expected in the near future, and various countries are already planning short ...

Morpho‐functional analyses of the jaw apparatus in the Blue‐and‐yellow Macaw (Ara ararauna, Psittaciformes, Aves): Adaptations to feeding behavior

The Anatomical Record, EarlyView.
Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates

The Strategic Role of Sustainability Certifications: A Multi‐Theoretical Framework and Comparative Analysis in the Global Wine Industry

Business Strategy and the Environment, EarlyView.
ABSTRACT Sustainability certifications are increasingly embedded in the governance and competitiveness of the wine sector, yet their strategic role remains under‐theorised. This study conceptualises certifications as multidimensional strategic mechanisms and conducts a comparative analysis of 50 schemes used in the global wine industry.
