Searching for Topological Semi‐Complete Bandgap in Elastic Truss Lattices

open access: yesAdvanced Science, EarlyView.
Ideal gapless nodes within clear bandgaps remain elusive in elastic systems, where degeneracies always hide in trivial bulk bands due to intricate modes. The work proposes a topological semi‐complete bandgap (exhibits a complete bandgap except for the inevitable topological degenerate points) in a 3D elastic truss lattice by tuning a supporting rod ...

Micro/Nanorobots for Combating Brain Disorders: Challenges, Advances, and Perspectives

open access: yesAdvanced Science, EarlyView.
Micro/nanorobots (MNRs) offer a transformative approach for precision therapy in brain disorders. By overcoming biological barriers and enabling controlled propulsion, targeted delivery, and real‐time imaging/tracking, MNRs pave the way toward effective, minimally invasive treatments. This review outlines the interplay between brain disease challenges,

MBE‐Grown ScAlN‐on‐Si Films: Enhancing In‐Plane Crystallinity for Extensional Mode BAW Resonators

open access: yesAdvanced Electronic Materials, EarlyView.
The achievement of in‐plane single crystallinity and a high piezoelectric modulus in epitaxially grown ScAlN films on AlN‐buffered Si (111) enables extensional mode ScAlN‐on‐Si bulk acoustic wave (BAW) resonators with an ultra‐high Q of ≈97k at 70.28 MHz, resulting in a frequency‐Q product of ≈6.86 × 1012, suitable for emerging wireless technologies ...

Spin Matters: A Multidisciplinary Roadmap to Understanding Spin Effects in Oxygen Evolution Reaction During Water Electrolysis

open access: yesAdvanced Energy Materials, EarlyView.
This roadmap offers a forward‐looking perspective on spin enhancement in the oxygen evolution reaction. It highlights how combining systematic experiments, advanced computational modeling, and novel magnetic, chiral, or hybrid materials can deepen the understanding of spin‐dependent catalytic mechanisms.
