Novel tungsten carbide nanorods: An intrinsic peroxidase mimetic with high activity and stability in aqueous and organic solvents

“…S4 in the Supporting Information). This may be explained by the facilitated decomposition of H 2 O 2 and the promoted stability of transition-metal complexes with reactive oxygen species in aprotic media (Todres 1985). As shown in Fig.…”

Dynamics and the Regiochemistry of Nitration of Toluene

“…The general nature of the mechanism was itself contested. The idea that electron transfer is involved in nitration has a long history in the literature . In reactions of highly electron-rich aromatics, Kochi and others were able to strongly support the viability of such mechanisms. , With less electron-rich arenes such as toluene, however, Eberson argued that the uphill electron transfer would be far too slow to account for the observed rates of reactions .…”

Rovibronic Spectroscopy of Sympathetically Cooled 40CaH+

“…. reaction mechanisms such as ionic reactions in organic chemistry [1,2] or the reactions proposed to occur in space [3,4]. Ion traps provide an isolated environment for the creation and study of reactive species whose spectra are lacking compared to their neutral counterparts.…”

“…In addition, the of full quantum controlled chemistry provides insight into the details of non-Arrhenius behavior such as tunneling and submerged barriers that may influence reaction kinetics at low temperatures and densities. Aside from astrochemistry, these ion-molecule reactions are important in understanding the fundamental processes underlying practical applications like plasma etching [55] and reactions in organic chemistry [1,2]. As important as the reactions are to organic chemistry in the identification of reaction pathways and predicting yields [2], this class of reactions has limited studies at the fundamental level [56].…”
