DedicatedtoProfessor Reshef Tenne on the occasion of his 75th birthdayRechargeable seawater batteries have gained recognition as key sustainable electrochemical systems by employing the near-infinite and eco-friendly catholyte seawater.H owever, their practical applications have been limited owing to the low chemicala nd electrochemical stabilityo ft he anode component. Herein, as tability-secured approach was developed by using sodium-biphenyl-dimethoxyethane solution as ar edoxactive functional anolytef or high-performances eawater batteries. This anolyte system shows high electrochemical stability, superior cycle performance, and cost-effectiveness over conventional electrolyte systems. Figure 2.

Sulfuryl fluoride gas is a key reagent
for SO2F transfer.
However, conventional SO2F transfer reactions have limited 18F-radiochemistry translation, due to the inaccessibility
of gaseous [18F]SO2F2. Herein, we
report the first SO2F2-free synthesis of aryl
[18F]fluorosulfates from both phenolic and isolated aryl
imidazylate precursors with cyclotron-produced 18F–. The radiochemical yields ranged from moderate to
good with excellent functional group tolerance. The reliability of
our approach was validated by the automated radiosynthesis of 4-acetamidophenyl
[18F]fluorosulfate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
