Synthesis and properties of novel betaine fluorocarbon surfactants

open access: yesJournal of Dispersion Science and Technology, 2021
In this study, a series of new betaine fluorocarbon surfactants (abbreviated as FSC-m) were synthesized with N,N-dimethyl-1,3-propane diamine, perfluoroalkyl sulfonyl fluoride, and sodium chloroacetate. The novel surfactants were characterized by FI-IR, 1H-NMR and 19F-NMR.

Capillary Electrophoresis Methods for the Characterization of Synthetic Nanoparticles

open access: yesELECTROPHORESIS, EarlyView.
Capillary electrophoresis (CE) can be applied to evaluate nanoparticle (NP) size, charge, and surface characteristics. Hyphenating CE with ICP‐MS and AF4 can provide comprehensive, multidimensional NP characterization. ABSTRACT Nanoparticles (NPs) exhibit properties distinct from bulk materials of identical chemical composition, with their behavior and

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).
