Customized Itinerant Frequency Combs by Cascaded Nonlinear Effects

open access: yesAdvanced 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

Experiments on Nonlocal Fluid‐Flow Metamaterials

open access: yesAdvanced Science, EarlyView.
A nonlocal fluid‐flow metamaterial composed of standard microfluidic tubes and connectors is designed. Hence, the current of the system at one position depends on the gradient of fluid flow at many other positions, leading to unusual alternating backward and forward laminar flows of water.

Longitudinal Awake Mouse Brain Imaging Using Functional Ultrasound and Functional Ultrasound Localization Microscopy

open access: yesAdvanced Science, EarlyView.
Awake longitudinal multimodal ultrasound imaging integrates functional ultrasound (fUS), ultrasound localization microscopy (ULM), and functional ULM (fULM) to characterize cerebrovascular function, microvascular architecture, and flow dynamics within the same animals over time.

Glutaminolysis Blockade‐Empowered Bimodal Nanodepot for Spatially Complementary Sono‐Thermal Ablation via PANoptosis and STING Activation Against Large Tumors

open access: yesAdvanced Science, EarlyView.
An injectable bimodal TCPD nanodepot disrupts glutaminolysis and TCA metabolism, sensitizing large tumors to spatially complementary sono‐thermal ablation for complete treatment coverage. This intervention induces mitochondrial and endoplasmic reticulum dysfunction, genotoxicity, and NAD+ depletion, converging to trigger PANoptosome assembly and ...

Large Electrostrain and High Optical Transmittance via Oxygen Octahedron Rotation Disordering in KNN Ceramics

open access: yesAdvanced Science, EarlyView.
Chemical disorder engineering reconfigures BO6 oxygen‐octahedron rotations in lead‐free K0.5Na0.5NbO3 ceramics from local ordering into a random distribution, dissolving the longstanding trade‐off between optical transparency and electromechanical strain.
