State of the Art of Low‐Frequency Acoustic Modulation: Intensity Enhancement and Directional Control

open access: yesAdvanced Science, EarlyView.
High intensity low‐frequency sound sources hold significant value in many fields. However, their long wavelength, strong penetrability, and tendency to diffract make direction control and intensity enhancement challenging. Acoustic generators and metamaterial‐based acoustic devices still face issues such as low energy efficiency, poor directional ...

Gut Microbiota Modulation by Inulin Improves Metabolism and Ovarian Function in Polycystic Ovary Syndrome

open access: yesAdvanced Science, EarlyView.
This work proposes a novel strategy targeting gut microbiota for managing polycystic ovary syndrome (PCOS). Inulin, a gut microbiota modulator, notably boosts the growth of short‐chain fatty acids (SCFAs)‐producers, represented by Bifidobacterium, thereby improving glucolipid metabolism and ovarian function of PCOS through suppressing the inflammatory ...

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.

Thermo‐responsive topological metamorphosis in covalent‐and‐supramolecular polymer architectures

open access: yesAggregate, Volume 3, Issue 6, December 2022., 2022
We report a thermo‐responsive topological metamorphosis in covalent‐and‐supramolecular polymer (CSP) architectures wherein supramolecular graft polymer (SGP) transforms into supramolecular polymer network (SPN) based on collaborative dynamic covalent bond chemistry and host−guest chemistry.
