Optical Responses From Zero Optical‐Path‐Length Object
This work address a fundamental question—what is the ultimately minimal embodiment of optical objects that produce useful optical effects? In fact, such an object does not require nonzero physical and optical‐path‐length volume as opposed to the conventional perception.

Compact Snapshot Hyperspectral Imaging With Neural Dispersion‐Engineered Metalens
A dispersion‐engineered metalens, designed via an end‐to‐end deep learning framework, encodes spectral information through wavelength‐dependent PSF shifts. Fabricated by two‐photon grayscale lithography, the ultrathin device demonstrates outstanding spatial‐spectral reconstruction in both indoor and outdoor scenes, positioning it as a promising ...

Toward Intelligent Multimodal Holography for Real‐Time Chemical Imaging of Dynamic Ion Separation
Intelligent multimodal holography integrates digital off‐axis holography, spectroscopic imaging, and AI‐driven reconstruction to visualize ion transport and chemical dynamics in real time. In this perspective paper, we outline how this approach enables label‐free, chemically specific monitoring of complex environments and discuss its potential to ...

Design and Application of Hybrid Collaborative Interaction Model for Game Scenarios
Image acquisition was first performed using a camera to capture gesture images. Next, the network entered the GR stage, where the collected images were used as input and processed through a Feature Pyramid Network (FPN) to complete feature extraction and region segmentation.

Stress‐induced switch. Under stress conditions, small extracellular vesicle release shifts from the constitutive ‘torn bag mechanism’ to exocytosis of multivesicular endosomes. https://BioRender.com/xn1pa1e. ABSTRACT The biogenesis of small extracellular vesicles (sEVs) is only partially understood.

Novel Non‐Cytotoxic Acylphosphinates and Acylphosphine Oxides Photoinitiators
Novel acylphosphine oxide (APO) and acylphosphinate photoinitiators based on DPO and DOPO were designed to investigate structure–property relationships including photochemical performance, polymerization efficiency and cytotoxicity. While DPO derivatives showed excellent reactivity, DOPO‐based systems also displayed good efficiency and significantly ...

High‐performance near‐infrared (NIR) organic light‐emitting diodes (OLEDs) were achieved by incorporating a one‐dimensional Bragg grating into a thermally cross‐linkable hole‐transporting layer via microtransfer molding. The optimized devices exhibit an emission peak at 880 nm, a maximum external quantum efficiency of 1.55%, and a peak radiant exitance
