23Na MAS NMR spectra of sodium–oxygen (Na–O2) cathodes reveals a combination of degradation species: newly observed sodium fluoride (NaF) and the expected sodium carbonate (Na2CO3), as well as the ...

A near 100% initiation efficiency and 100% regioselectivity at the methylacrylic C═C bond was realized by bulky Lewis pairs-mediated polymerization of polar divinyl monomers such as 4-vinylbenzyl ...
