Holographic Mapping of Orbital Angular Momentum using a Terahertz Diffractive Optical Neural Network

open access: yesAdvanced Intelligent Discovery, EarlyView.
A compact six‐layer diffractive optical neural network enables direct recognition and spatial mapping of terahertz (THz) orbital angular momentum (OAM) beams. Fabricated by 3D printing, the system distinguishes nine OAM modes and their superpositions with high fidelity, good efficiency, and low crosstalk, offering a scalable solution for THz ...

Monitoring the Microwave Synthesis of d0‐Free Disordered Rocksalt Cathodes Using In Situ Infrared Pyrometry

open access: yesAngewandte Chemie, EarlyView.
Despite its promise for producing metastable materials, the mechanisms underlying solid‐state microwave synthesis remain poorly understood. By combining in situ thermography with x‐ray diffraction and solid‐state NMR, this study uncovers a surprising order–disorder–order reaction pathway during the microwave synthesis of the Li1.1Mn0.9O1.9F0.1${\rm Li ...

A Random Degradation Aggregation Network With Temporal-Spatial Attention for Satellite Video Super-Resolution

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
In recent years, video super-resolution (VSR) has achieved significant progress. However, most existing VSR methods rely on fixed and known degradation models, such as bicubic downsampling, which limits their effectiveness in real-world scenarios ...

From Data to Discovery: Machine Learning–Enabled Intelligent Characterization of Two‐Dimensional Materials

open access: yesAdvanced Intelligent Discovery, EarlyView.
Machine learning serves as a central engine for the intelligent characterization of two‐dimensional materials by integrating multimodal techniques, including optical microscopy, spectroscopy, electron microscopy, and scanning probe microscopy (SPM). This unified framework enables automated, high‐throughput, and quantitative extraction of structural ...

Heat‐ and Light‐Directed Cycloadditions Enable a Pericyclic Cascade Reaction From a Molecular Precursor

open access: yesAngewandte Chemie, EarlyView.
A multi‐stimuli‐responsive material is designed that responds to light, heat, and mechanical force through distinct chemical reaction pathways. The pathway is directed by self‐assembly and the applied stimulus. A novel pericyclic reaction cascade is also achieved, and the mechanism is supported through density functional theory calculations.

Small‐Scale Magnetic Peristaltic Soft Robot With Mobility and Transport Capabilities

open access: yesAdvanced Intelligent Systems, EarlyView.
This study introduces a miniature, untethered soft magnetic microrobot with peristaltic capabilities for both locomotion and cargo transport. Eight helically magnetized elastomeric strips deform under rotating fields (10–80 mT, 1–5 Hz), enabling movement across rods and lumina at up to 4.1 body lengths min‐¹.

Stacking the Deck to Make Materials With Atypically Short Heterometallic d8 M(II)···Au(III) Bonds

open access: yesAngewandte Chemie, EarlyView.
Tetracyanoplatinate(II) and tetracyanoaurate(III), through self‐assembly in the presence of KCl, crystallize from water to form a one‐dimensional chain featuring the first reported PtII···AuIII metallophilic interaction with a very short distance of ∼3.0 Å between the metal centers.

Toward Fully Soft and Multifunctional Shape Sensing via Optical Waveguide Arrays

open access: yesAdvanced Intelligent Systems, EarlyView.
This work develops a sheet made with arrays of soft optical fibers that can reconstruct its 3D surface shape. Synergy of the waveguides’ responses to bending and pressing force allows shape reconstruction with resilience to damage. Applied onto surfaces of robotic or living systems, our design can be implemented in virtual reality, teleoperation ...

Mapping Proton‐Coupled Electron Transfer With Real Space Coordinates

open access: yesAngewandte Chemie, EarlyView.
We explore how proton‐coupled electron transfer (PCET) proceeds on a potential energy surface defined by two coordinates for proton and electron transfer that are obtained from quantum chemical calculations. The two‐dimensional maps for PCET show distinct characteristics for concerted proton–electron transfer and hydrogen atom transfer.
