Van der Waals epitaxy suppresses thermal rupture in ultrathin metals

Wenxiang Wang, Jiaxing Wang, Guotong Wang, Zhichao Yin et autres

Metal films are indispensable to modern electronics, yet their continued downscaling is fundamentally limited by thermodynamic instability. In particular, ultrathin metals can exhibit liquid-like Plateau–Rayleigh instability and rupture at temperatures far below their bulk melting point, creating a long-standing challenge for both …

Control of ice thickness in cryo-EM via confinement

Liming Zheng, Jiling Song, Xiaole Zhao, 曹家枞 et autres

Achieving thin ice with optimal thickness is a prerequisite for successful cryo-EM analysis of embedded macromolecules. Despite decades of effort, precise control of ice thickness in cryo-EM remains a major challenge. Here, we reveal that the intrinsic instability of sub-100-nm liquid film, …

Explosion Mechanics Roadmap

Qiang Wu, Jianbo Hu, Minqiang Jiang, Xiaohu Yao et autres

Explosion mechanics originated from China’s “Two Bombs and One Satellite” project and was named by Hsue-Shen Tsien in 1963. It primarily studies the occurrence patterns of explosions, as well as the utilization, control, and protection of their mechanical effects. As an interdisciplinary …

Suppressed Rupture of Thin Metal Films via van der Waals Epitaxy

Wenxiang Wang, Jiaxing Wang, Guotong Wang, Zhi‐Chao Yan et autres

Ultrathin metal films exhibit liquid-like instabilities, rupturing via surface diffusion far below their melting points. This behavior constrains thermal budgets for advanced integrated circuits and emerging 2D-crystal devices. Here, we demonstrate that these instabilities can be fundamentally suppressed using graphene as a …

Programming Sequential Twist–Buckling and Fracture in Metamaterials via Hetero-chiral Design

Xiaotang Lu, Lin Yu, Longchao Dai, Chaonan Cong et autres

This study presents a hetero-chiral metamaterial leveraging two helical angles to synergistically enhance strength, and toughness — thereby overcoming the typical trade-off among these properties. Under compression, the 3D-printed optimal hetero-chiral structure exhibited a 3.4-fold increase in stiffness, a 2.2-fold increase in …
