(Poly)Borylated Species as Modern Reactive Groups toward Unusual Synthetic Applications

open access: yesAngewandte Chemie, EarlyView.
In this review, we spotlight recent breakthroughs in α‐polyboron‐substituted carbon‐centered intermediates (carbanion, carbocation, radical, and carbene) and polyborylated alkenes. By bridging fundamental reactivity with the application potential of these extraordinary species, we hope this review will serve as a roadmap for harnessing these unique ...

Mitigating Thermal Runaway in Lithium Metal Batteries With Flame‐Retardant Magnesium Hydroxide Nanocomposite Gel Electrolytes

open access: yesAdvanced Energy Materials, EarlyView.
Lithium‐ion batteries are ubiquitous but pose significant safety risks especially with high‐energy‐density electrode materials. This study reports a nanocomposite gel electrolyte (NGE) with a flame‐retardant magnesium hydroxide (MH) matrix, which offers robust mechanical properties, high ionic conductivity, and enhanced thermal safety.

Dynamic Confinement Approach for High Metal Loading Single‐Atom Catalysts Based on Covalent Organic Frameworks

open access: yesAngewandte Chemie, EarlyView.
We introduced a new synthetic strategy for the preparation of high metal loading crystalline single‐atom catalysts based on covalent organic frameworks with atomically distributed Pd ions and metal contents of up to 22.2 wt%. Theoretical simulations reveal that the crystalline framework dynamically confines Pd atoms between different binding sites ...

Phase‐Change Alloys Enable Localized Reversible Stiffening and Actuation in Steerable Eversion Tip‐Growing Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents a tip‐growing eversion robot that uses phase‐changing alloys for reversible stiffening and localized actuation, achieving 43× stiffness modulation, 15× force amplification, and segmental steering. The system enables precise navigation and force delivery in constrained, tortuous pathways.

Discovery of a First‐in‐Class Covalent Allosteric SHP1 Inhibitor with Immunotherapeutic Activity

open access: yesAngewandte Chemie, EarlyView.
A covalent allosteric inhibitor M029 was discovered for SHP1, a novel target for immunotherapy. M029 binds to a cryptic Cys remote from the active site, exhibits robust target engagement, and blocks tumor progression by stimulating antitumor immune response.
