Near‐Field Acoustic Imaging Using Fiber‐Optic Distributed Acoustic Sensing and Beamforming Techniques

open access: yesAdvanced Science, EarlyView.
This work introduces a beamforming‐based method to generate acoustic images from fiber‐optic distributed acoustic sensing (DAS) data. By performing 2D scanning around the sensing fiber, the approach enables near‐field imaging and localization of acoustic sources, even in regions distant from the fiber. A data‐driven DAS channel selection improves image

Composition‐Controlled Cathode Protective Layer via Powder‐Atomic Layer Deposition for All‐Solid‐State Batteries

open access: yesAdvanced Science, EarlyView.
Composition control of the LiZrO protective layer via atomic layer deposition modulates its ionic and electronic conductivities, directly affecting interfacial stability and electrochemical performances of the sulfide‐based all‐solid‐state batteries. This study establishes the composition of the protective layer as an essential design axis for cathode ...
