Interface‐Confined Cavitation at an MXene/TiO2 Schottky Heterointerface for Non‐Thermal Juice Preservation

Advanced Science, EarlyView.
This work establishes an MXene/TiO2 Schottky heterointerface for non‐thermal sonocatalysis. Interface‐confined cavitation and dynamic Ti3+/V₀ shuttles drive charge transport and reactive oxygen species (ROS) generation. The platform achieves 3‐log pathogen reduction while retaining heat‐labile nutrients in complex food matrices, redefining sonocatalyst

A CT Lesion Foundation Model for Non‐Invasive Assessment of Hepatocellular Carcinoma Aggressiveness and Prediction of Recurrence Risk

Advanced Science, EarlyView.
A computed tomography lesion foundation model, built by sequential self‐supervised pretraining on generic and hepatocellular carcinoma‐specific lesion images, non‐invasively assesses microvascular invasion and pathological grade from contrast‐enhanced CT and stratifies postoperative recurrence risk.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

Advanced Electronic Materials, EarlyView.
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.
