Side Chain Elimination Enables Low‐Cost Fused‐Ring Acceptors and Reveals a Compact Tetrameric Structure for High‐Photocurrent Organic Solar Cells

Advanced Science, EarlyView.
β‐side chain elimination enables cost‐effective fused‐ring acceptors, JSM5 and JSM6, with simplified synthesis. The observed compact tetrameric structures induced by S···N intermolecular interactions lead to 3D charge transport and enhance intermolecular connectivity, delivering high short‐circuit current density up to 28 mA cm−2, a step closer to the ...

PancDS in Real‐World Practice: A Prospective Multicenter Validation of a Clinical Decision‐Support System Bridging Experience Gaps in Pancreatic Lesion Diagnosis

Advanced Science, EarlyView.
A biomimetic artificial intelligence system, PancDS, has been developed to distinguish pancreatic ductal adenocarcinoma from mass‐forming pancreatitis by adaptively integrating clinical data, radiomics, and deep learning features. Validated across multicenter, reader‐study, and prospective settings, PancDS improves diagnostic accuracy, particularly for

Trap Depth Modulation and Antenna Effect of Organic Ligands for Enhancing Rare‐Earth Long Persistent Luminescence

Advanced Science, EarlyView.
Different from the current research trends that mainly focus on optimizing a single color system, a universal organic–inorganic hybrid strategy is proposed, aiming to synergistically enhance the luminescent properties of red, green, and blue multi‐color inorganic long‐persistent phosphorescent materials by trap depth modulation and antenna effect of ...

An Integrated DNA Nanoprobe for Intranuclear Imaging and in Situ Profiling of OGG1 Activity

Advanced Science, EarlyView.
The TP‐SA nanoprobe, integrating an AS1411 aptamer for nuclear delivery and a FRET array for signal amplification, enables real‐time tracking of nuclear OGG1 activity. It reveals cell‐line‐specific basal OGG1 levels and shows clinical promise using pneumonia patients’ lavage fluid.
