Topology‐Optimized Bound States in the Continuum with High‐Q Acoustic Field Enhancement

open access: yesAdvanced Science, EarlyView.
This study presents a topology optimization method for acoustic metamaterials, achieving high‐Q resonances by redesigning a single unit cell within a periodic array. The design enables precise pressure confinement and energy trapping, validated through experiments.

Cyclo‐N9−: a Novel 5/6 Fused Polynitrogen Anion for High Energy Density Materials

open access: yesAdvanced Science, EarlyView.
This study presents a novel 5/6 fused polynitrogen anion, cyclo‐N9−, which is assembled with four cations to form energetic salts. The computational results reveal that the energy densities and detonation performances of these systems are far superior, even surpassing those of CL‐20.

Uncover Hidden Physical Information of Soft Matter by Observing Large Deformation

open access: yesAdvanced Science, EarlyView.
Detecting internal abnormalities in soft matter remains challenging due to its heterogeneous nature. This study introduces a method that infers hidden physical properties by matching observed deformation with simulation through parallel Bayesian optimization.

A Hollow Shell‐Lattice Soft Robot in Flexible Pipelines with Flowing Fluids

open access: yesAdvanced Science, EarlyView.
This study proposes a novel shell‐lattice robot with hollow bodies, capable of crawling through pipes with flowing fluids of high velocities and viscosities and mixed with impurities. The robot also features capabilities of crawling with high payloads, in curved pipes, and unthethered crawling. These unique properties make this robot high promising for
