2562por D’Souza, Malcolm J., Knapp, Jaci A., Fernandez-Bueno, Gabriel A., Kevill, Dennis N.“…For 1, the results indicate that dual side-by-side addition-elimination and ionization pathways are occurring in some highly ionizing solvents due to the presence of the electron-donating γ-methyl group. For 2, the analyses indicate that the dominant mechanism is a bimolecular one where the formation of a tetrahedral intermediate is rate-determining.…”

As a result, the fluorescence quantum yield of the CDs was found to increase with increasing Ca(OH)(2) content in the reaction process. …”

Thus, it inhibits the oxidation of lipids by scavenging chain-initiating water-soluble peroxyl radicals and chain-carrying lipid peroxyl radicals. …”

We further demonstrate that, using this electron rich arylhydroxamic acid, clear labeling was achieved on a subcellular level in living cells that were transfected with a genetically targeted NAT to the nucleus or the cytosol.…”
