Supramolecular Degraders: An Emerging Paradigm in Targeted Protein Degradation

Advanced Science, EarlyView.
Dynamic supramolecular assembly reshapes targeted protein degradation by coordinating modular degrader construction, delivery, functional integration, and intracellular assembly or activation across proteasomal, endosomal–lysosomal, and autophagy–lysosomal pathways.

Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)

Angewandte Chemie, EarlyView.
Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

“Lithium‐Free” Anode Solid‐State Batteries Enabled by 3D Structured Miec Garnet

Advanced Energy Materials, EarlyView.
“Lithium‐free” anode solid‐state batteries can maximize energy density by eliminating excess lithium metal but are limited by unstable lithium nucleation and poor lithium reversibility at solid interfaces. A mixed ionic and electronic conducting garnet scaffold promotes uniform lithium deposition within a three‐dimensional porous framework at low ...

Chiral Fjord‐Edged Nanographenes Constructed by Allylic‐Migration‐Mediated Cyclization

Angewandte Chemie, EarlyView.
A novel allylic‐migration‐mediated cyclization strategy enables the construction of two fjord‐edged nanographenes without steric blocking groups. The resulting non‐planar molecules exhibit remarkable chiroptical properties, with an absorption dissymmetry factor surpassing those of pristine [5]helicene and previously reported fjord‐edged nanographenes ...

Dynamic Behavioral Profiling for User Authentication Using Binary Pressure Sequences and Grip Patterns via a Soft Stacking Ensemble

Advanced Intelligent Systems, EarlyView.
A smartphone‐embedded fabric‐strip sensing interface captures side‐pressure sequences and grip‐position patterns for behavioral authentication. Probability‐based soft stacking integrates class‐wise predictive probabilities from multiple learners to improve verification‐style discrimination, supporting a sensor‐integrated mobile‐security framework that ...

Ring‐Retentive Allylation of Cyclopropanols Through Interception of Enolized Homoenolates by π‐Allylpalladium

Angewandte Chemie, EarlyView.
Cyclopropanols undergo palladium‐catalyzed, zinc‐mediated allylation with allyl acetates: the ring opens transiently to an enolized homoenolate, is intercepted by π‐allylpalladium, and recloses to furnish β‐allylated cyclopropanols. This formal “allylic cyclopropylation” broadens the reaction space for ring‐retentive functionalization of cyclopropanols.

New Technologies for Producing Bicycle Hub Forging

MATEC Web of Conferences, 2018
The paper presents the results of research on two new forging processes for producing bicycle hub forgings in a three-slide forging press. The first process is related to producing a forging with an axial cavity by flashless forging.
