Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Amido‐Amine Co(II) Precursor‐Based Atomic/Molecular Layer Deposition Processes for Cobalt‐Organic Thin Films and Their Thermal Conversion to CoO Thin Films

Advanced Materials Technologies, EarlyView.
Three new atomic/molecular layer deposition processes are developed for Co‐organic thin films using a promising all‐nitrogen‐coordinated cobalt precursor. The study examines film growth, reaction mechanisms, chemical stability, and decomposition pathways of the resulting films through extensive characterization techniques and DFT calculations ...

S3RL: Enhancing Spatial Single‐Cell Transcriptomics With Separable Representation Learning

Advanced Science, EarlyView.
Separable Spatial Representation Learning (S3RL) is introduced to enhance the reconstruction of spatial transcriptomic landscapes by disentangling spatial structure and gene expression semantics. By integrating multimodal inputs with graph‐based representation learning and hyperspherical prototype modeling, S3RL enables high‐fidelity spatial domain ...
