3D‐Printed Shark‐Inspired Soft–Hard Hybrid Underwater Robot With Buoyancy Control and Onboard Vision

Advanced Intelligent Systems, EarlyView.
A fully self‐contained shark‐inspired underwater robot is developed using 3D‐printed soft–hard hybrid structures, servo‐driven propulsion, and pump‐based buoyancy control. The platform achieves three‐dimensional locomotion and onboard vision‐based target tracking, offering a reproducible and accessible framework for biomimetic underwater robot research.

Peroxide‐Assisted Solvate Engineering Enables Record‐High Birefringence in a Solar‐Blind Transparent Crystal

Angewandte Chemie, EarlyView.
H2O2‐directed solvate engineering reorganizes ∞[4HP] (4‐hydroxypyridine) chains from a crossed arrangement into a nearly parallel packing through strengthened hydrogen‐bonding interactions. The resulting peroxide‐containing crystal, 4HP·H2O2, exhibits a solar‐blind UV cutoff edge (278 nm) and giant birefringence (0.609 @ 546 nm). This work demonstrates

Polarity‐Directed Synthesis of an Exfoliable 2D Polyoxometalate‐Based Metal‐Organic Framework for Noble Metal‐Free Alkyne Transfer Semi‐Hydrogenation

Angewandte Chemie, EarlyView.
Exfoliation of 2D nanosheets based on polyoxometalate metal‐organic frameworks (POMOFs) gives access to nanostructures with selective catalytic reactivity for the alkyne transfer semi‐hydrogenation which outperform the bulk references and rival some classical noble metal‐based catalysts.

Mitochondria‐Damaging Self‐Reporting Probe for Cancer Therapy

Angewandte Chemie, EarlyView.
We developed a class of self‐reporting cationic chemotherapeutic probes that selectively induce mitochondrial damage and apoptosis in cancer cells. Their unique mitochondria‐to‐nucleus fluorescence migration enables real‐time visualization of the therapeutic process. ABSTRACT Mitochondrial damage induced by chemotherapeutic agents through disruption of

Controlling the Guanidinium Cation Rotation by Cation–π Interactions

Angewandte Chemie International Edition, EarlyView.
A lanthanide π‐container has been employed to trap a guanidinium cation inside the aromatic cavity by cation–π interactions. X‐ray crystallography and solid‐state nuclear magnetic resonance (NMR) spectroscopy at fast magic‐angle spinning (MAS) frequencies have been utilized to probe the underlying host–guest interactions.
