Unified Synthesis of Unconventional α‐Polyhalogenated Amines Through Hydroaminoalkylation

open access: yesAngewandte Chemie International Edition, EarlyView.
A unified, redox‐neutral method that transforms alkenes and alkynes into α‐polyhalomethyl amines using stable hemiaminal reagents is reported. This approach enables access to CF3, CF2H, CF2Cl, and CFClH motifs, expanding halogenated amine space with broad substrate scope, functional group tolerance, and applicability to late‐stage modification of drug ...

A Fixed‐Charge Interphase Synchronizes Ion Transport to Suppress Space‐Charge‐Driven Inefficiency Under Nanoliter Confinement

open access: yesAngewandte Chemie International Edition, EarlyView.
Electrochemical energy storage breaks down under extreme miniaturization, where interfaces and space‐charge dominate device behavior. This work introduces a fixed‐charge selective interphase (FCSI) integrated into a twin‐tube micro‐Swiss‐roll architecture.

Cooperative Redox Catalysis of N2O Decomposition by Short‐Range RhOx and CeOx Anchored to Co3O4

open access: yesAngewandte Chemie International Edition, EarlyView.
A short‐range Rh–O–Co–O–Ce interfacial moiety drives low‐temperature N2O decomposition via a cooperative redox cycle. Operando modulated‐excitation XAS with phase‐sensitive detection (ME‐XAS + PSD) tracks rapid, reversible Rh oxidation coupled to Co reduction.

Citric‐Acid Polyester‐Modified Melamine–Formaldehyde Resins: Mechanistic Insights and Implications for Greener Decorative Laminates

open access: yesJournal of Applied Polymer Science, EarlyView.
Driven by the need for more sustainable materials in the laminate industry, poly(glycerol citrate) was introduced as a bio‐based modifier that significantly altered the cure kinetics and structural evolution of melamine–formaldehyde resins. Correlated FTIR, DSC, TGA, and rheological analyses revealed accelerated network formation, enabling lower ...

The cranial, mandibular, and hyoid anatomy of softshell turtles (Trionychidae): A revised character list for phylogenetic analysis

open access: yesThe Anatomical Record, EarlyView.
Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...
