A Waterborne Epoxy Vitrimer: Enabling Moisture‐Driven Actuation, Continuous Moist‐Electric Generation, and Water‐Assisted Degradation

Advanced Science, EarlyView.
A catalyst‐free waterborne epoxy vitrimer has been developed through the curing of 1,4‐butanediol diglycidyl ether with L‐tartaric acid. The incorporation of abundant hydroxyl groups and the neighboring group participation effect enable this vitrimer to exhibit rapid stress relaxation and achieve complete degradation in hot water.

A Bidirectional Tuned Mass Damper for Flutter Suppression in Ultra-Large Offshore Wind Turbine Flexible Blades

Journal of Marine Science and Engineering
As onshore space resources become exhausted, the migration of wind turbines to offshore areas is an inevitable trend. The blades of offshore wind turbines are typically over 100 m long, and this increased nonlinearity in the blades escalates the risk of ...

Electrosensitive Heterogeneous Short Fibers via Acousto‐Electric Coupling for Sequential Bone Regeneration in Infectious Defects

Advanced Science, EarlyView.
Electrosensitive heterogeneous short fibers can accurately respond to ultrasonic field regulation through the synergistic interaction of piezoelectric and conductive dual elements. At an ultrasound intensity of 1.5 W cm−2, it can effectively activate bacterial peroxisome and necrotic apoptotic pathway and promote bacterial apoptosis.

Forsythoside E Alleviates Liver Injury by Targeting PKM2 Tetramerization to Promote Macrophage M2 Polarization

Advanced Science, EarlyView.
Here, the study shows for the first time that Forsythoside E (FE) can promote PKM2 tetramerization by binding to its K311 site. Furthermore, it induces metabolic reprogramming of macrophages and inhibits NLRP3 expression. Finally, it can alleviate sepsis‐induced liver injury by promoting M2 anti‐inflammatory polarization.

Targeting G3BP1 Condensate Topology Promotes Stress Granule Assembly via m6A‐IGF2BP1 for Ischemic Stroke Rescue

Advanced Science, EarlyView.
Our research reveals that small‐molecule icariin (ICA) directly binds Ras‐GTPase‐activating protein SH3 domain‐binding protein 1 (G3BP1), inducing conformational change and oligomerization. This interaction confers neuroprotection by recruiting insulin‐like growth factor 2 mRNA‐binding protein 1 (IGF2BP1) and modulating N6‐methyladenosine (m6A ...

Ultrasensitive Diamond Cantilever‐Based Optical Microphone

Advanced Science, EarlyView.
The first demonstration that high quality diamond cantilevers function as high‐sensitivity acoustic transducers is reported, combining CVD diamond cantilevers and an extrinsic Fabry‐Perot optical configuration. High transduction efficiency yields record sensitivity (51.5 VPa−1) and MDP (0.018 µPa/Hz$\rm {\sqrt {Hz}}$), enabling durable, low‐noise ...

Alternative Pathway for Methyl Supply through the Coupling of SHMT1 and PEMT to Maintain Astrocytic Homeostasis in Parkinson's Disease

Advanced Science, EarlyView.
In Parkinson's disease, SHMT1 downregulation disrupts its interaction with PEMT in astrocytes, reducing SAM levels. This leads to H3K4me1 hypomethylation and decreased Slc1a2/Glul expression, ultimately exacerbating neuroexcitotoxicity and dopaminergic neuron loss.
