Rapid Epoxy Polymerization Induced by Aliphatic Cyclic Tertiary Amines: The Roles of Nucleophilicity and Leaving Ability

open access: yesMacromolecular Rapid Communications, EarlyView.
Quinuclidine, as a tertiary amine, can rapidly polymerize epoxy groups. We investigated the relationship between amine properties and polymerization behavior by monitoring the reactions of various tertiary amines with epoxy groups. The results indicate that quinuclidine, the most nucleophilic amine examined, promotes epoxy polymerization.

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Mechanical and Electrochemical Performance of a PETEA‐Based Solid‐State Electrolyte for Multifunctional Structural Battery Composites

open access: yesNano Select, EarlyView.
Multifunctional structural battery composites can store electrical energy while bearing mechanical loads, thereby reducing parasitic mass and volume. We present a novel solid‐state PETEA‐based electrolyte, which can be cured in situ after infiltration into the reinforcement fibers in its monomer form.
