ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Molecular dynamics simulations reveal that the addition of weakly coordinating solvents disrupts stable Na+ solvation with various coordinating configurations, accelerating solvents exchange and promoting Na+ migration. The optimized electrolyte achieves the highest ionic conductivity as well as the fractional ionic conductivity of Na+ of 3.68 ± 0.36 ...

Mass 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).
