PLXDC2 siRNA‐Mediated Intervention Attenuates Microglial Senescence Through cGAS‐STING Signaling

Advanced Science, EarlyView.
PLXDC2 was identified as a microglial target in Parkinson's disease through human and mouse single‐cell analyses. Ferritin‐armed biomimetic nanovesicles delivered PLXDC2 siRNA, deferoxamine, and CeO2 nanoparticles across the blood–brain barrier, reducing cGAS‐STING activation, iron burden, oxidative stress, and senescence in microglia, thereby ...

Customized Itinerant Frequency Combs by Cascaded Nonlinear Effects

Advanced Science, EarlyView.
A cascaded third‐order nonlinear system generates an itinerant frequency comb with the comb center frequency decoupled from the cavity resonance. This enables arbitrary spectral scaling, flexible spacing adjustments, and real‐time central‐frequency engineering, allowing comb splicing and subdivision. The resulting versatility and reconfigurability open

Lumped Circuits Modeling of Dynamic Energy Transfer in Triboelectric Nanogenerators with Nonlinear Electromechanical Coupling

Advanced Energy Materials, EarlyView.
This work presents a lumped electromechanical model that identifies resonance, impedance matching, and structural dynamics as key determinants of energy transfer in triboelectric nanogenerators. Experimentally validated across mechanically distinct devices, the framework also shows that excitation‐dependent responses enable simultaneous energy ...
