Ultrahigh Stiffness and Energy Absorption Properties of Isotropic Metallic Closed Cell Microlattices

Small, Volume 22, Issue 35, 23 June 2026.
True closed cell microlattices without holes are fabricated for the first time using a novel Laser Sheet Fusion additive manufacturing technique. These microlattices exhibited isotropy in stiffness and surprisingly, strength and plasticity as well, despite orientation‐dependent failure mechanisms. Furthermore, material work hardening is shown to be key

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

High Voltage, Volume 11, Issue 3, Page 601-619, June 2026.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Tailored TMES‐Modified Polyimide–Silica Aerogels for Enhanced Mechanical Performance and High‐Temperature Aerospace Applications

Natural Sciences, Volume 6, Issue 2, April 2026.
ABSTRACT The development of high‐performance thermal insulation and lightweight materials in aerospace applications requires overcoming the limitations of conventional aerogels. While polyimide (PI) aerogel offers flexibility and thermal stability, it suffers from shrinkage and a hydrophilic nature.

Dual‐Function In Situ Ti3(Cu,Al)3O Reinforcement for Simultaneous Strengthening and CTE Reduction in Sapphire/TC4 Active‐Brazed Joints

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT The thermal expansion mismatch between sapphire and Ti‐6Al‐4V (TC4) alloy has traditionally limited the shear strength of ceramic‐metal joints to ≤ 170 MPa. In this study, active brazing with Ag‐35.25Cu‐1.75Ti (wt%) leads to the formation of a dual‐function microstructure, wherein uniformly dispersed submicron Ti3(Cu,Al)3O particles embedded ...
