Dynamic Obstacle Avoidance of Metamorphic Microrobots Using Concentric Sector Navigator

Advanced Intelligent Systems, EarlyView.
Metamorphic magnetic microrobots are navigated using a concentric sector navigator for dynamic obstacle avoidance in both microroller and swarm states. After microroller transport, citrate‐triggered dissolution releases nanoparticles that reassemble into a controllable swarm.

A Compact Multijoint Finger Motion Sensing Module for Flexible Exoskeleton Applications

Advanced Intelligent Systems, EarlyView.
Addressing the motion estimation gap in underactuated wearable electronics, a highly integrated sensor alongside a customized readout circuit is proposed. Featuring a screen‐printed layout and optimized horseshoe geometry, this design establishes an optimal feedback mechanism for flexible hand exoskeletons while eliminating wiring clutter.

Distinct Molten‐Globule Conformations in an Interacting Protein Domain Resolved by 19F NMR of Fluoroproline Residues

Angewandte Chemie, EarlyView.
Modifying the conformational ensemble of “molten‐globule” protein by the site‐specific incorporation of stereoisomeric 4‐fluoroproline residues modulated its binding affinity and aggregation behavior. 19F NMR spectroscopy enabled the detection of key interactions responsible for structural and dynamic changes. ABSTRACT Recently, the application of deep

Vision‐Based Tactile Finger Integrating Fingerpad and Nail Sensing for Robotic Manipulation

Advanced Intelligent Systems, EarlyView.
This vision‐based tactile finger captures nail force and fingerpad force, contact position, and in‐plane orientation with one internal camera. An external camera recognizes the target and presets finger inclination from object height. The compact dual‐sensing design supports tactile‐guided table contact and reliable grasping of objects ranging from ...

Microenvironmental Tuning in Isostructural Conjugated Metal–Organic Frameworks for Superior Photocatalytic H2O2 Generation

Angewandte Chemie, EarlyView.
Two isostructural conjugated‐MOFs (Fe‐Tp and Mn‐Tp) photocatalysts were engineered with nonequivalent microenvironmental redox tuning for hydrogen peroxide production. The manganese analog engages both the oxygen reduction reaction and the water oxidation reaction while suppressing decomposition, delivering 10 487 µmol g−1 h−1 with an apparent quantum ...

Adipose‐derived mesenchymal stem cell injection into the KI10 acupoint mitigates cartilage damage in KOA rats through PGE2‐mediated α7nAChR/NF‐κB pathway

Animal Models and Experimental Medicine, EarlyView.
In our research, KOA rat models were established and treated with ADSC injection into the KI10 acupoint. Pain relief, behavioral function, and joint structural improvements were systematically assessed using ethological tests, imaging, histopathological staining, transmission electron microscopy, and molecular analyses.

pH‐Driven Actuation of Unmodified DNA Origami Rectangles

Angewandte Chemie, EarlyView.
Unmodified DNA origami rectangles exhibit a reversible transition between planar and tubular states driven by near‐neutral pH changes. This behavior arises from crossover‐mediated mechanical coupling of overwound DNA and extends to dimers and nanoribbons, enabling the formation of nanotube architectures without added motifs or chemical modification ...
