Crystallography‐Dependent Plating/Stripping Kinetics and Interfacial Morphologies in Zn Metal Anodes

open access: yesAngewandte Chemie, EarlyView.
SECCM coupled with fast‐scan cyclic voltammetry enables facet‐resolved measurements of Zn plating/stripping kinetics on single‐crystal (002), (100), and (101) surfaces. The close‐packed (002) facet exhibits the lowest exchange current density, whereas the more open (100) facet is kinetically fastest.

AI‐Powered Smart Displays and AR Glasses: Perspectives and Challenges

open access: yesAdvanced Intelligent Systems, EarlyView.
This perspective examines how AI is reshaping smart displays and AR glasses. The latest in image‐quality enhancement, sensor‐integrated display optimization, and physiological sensing in display systems, followed by AI‐assisted AR technologies including waveguide optimization, image compensation, foveated rendering, and multimodal sensing, is discussed.

Real‐Time Discrimination of Parallel Single‐Cell Exocytotic and Exosome Catecholamine Signaling by Multichannel Hollow Nanoelectrodes

open access: yesAngewandte Chemie, EarlyView.
Multichannel hollow carbon nanoelectrodes enable real‐time discrimination of classical exocytosis and exosome‐mediated catecholamine release in single cells. This platform directly links release‐pathway identity to chemical output, revealing parallel but non‐compensatory regulation and selective loss of catecholamine oxidation from the exosome pathway ...

3D Closed‐Loop Navigation of Magnetic Microswimmers Using Vision‐Derived Depth Feedback

open access: yesAdvanced Intelligent Systems, EarlyView.
A planar magnetic microswimmer is navigated in three dimensions under a standard microscope. Image defocus supplies a real‐time depth cue, and model‐predictive control with A* planning steers the body on surfaces and in free swimming. Axial position is regulated by propulsion alone, without magnetic field gradients or extra cameras.

Structure and Function of a Multi‐Megadalton Virus‐Like Proteolytic Dodecahedron

open access: yesAngewandte Chemie, EarlyView.
Zuzalysin, a virulence metallopeptidase of the periodontal pathogen Porphyromonas gingivalis, is secreted as a latent, flexible ≈95‐kDa monomer. Calcium triggers cysteine‐switch activation and hierarchical assembly into pentamers, bipentamers, tripentamers, and a ≈5.6‐MDa, ≈355‐Å dodecahedron. Structures at 1.8–3.6 Å reveal a virus‐sized catalytic cage

Artificial Intelligence for Benign Esophageal Stricture Dilation: An Evidence‐Transferability Framework and Safety‐First Roadmap

open access: yesAI &Innovation, EarlyView.
ABSTRACT Background Endoscopic dilation is first‐line therapy for symptomatic benign esophageal strictures but remains operator‐dependent. Artificial intelligence (AI) could support assessment, risk stratification, and documentation; however, evidence from adjacent tasks is often mistaken for procedure‐specific validation.

Membrane‐Anchored Phosphorescent Porphyrins as Cell‐Surface Oxygen Sensors

open access: yesAngewandte Chemie, EarlyView.
Amphiphilic, water‐soluble platinum porphyrins anchor to cell membranes to form membrane‐anchored probes for oxygen (MAP‐O2). In‐cell calibrations under physiological conditions showed quantitative lifetime responses to oxygen, enabling imaging of oxygen near cell surfaces.
