Carboxylic acids and light interact to affect nanoceria stability and dissolution in acidic aqueous environments [PDF]

open access: yesBeilstein Journal of Nanotechnology, 2023
Cerium atoms on the surfaces of nanoceria (i.e., cerium oxide in the form of nanoparticles) can store or release oxygen, cycling between Ce3+ and Ce4+; therefore, they can cause or relieve oxidative stress within living systems.

Electrochemical Borylation of Carboxylic Acids [PDF]

open access: yesProceedings of the National Academy of Sciences, 2021
A simple electrochemically mediated method for the conversion of alkyl carboxylic acids to their borylated congeners is presented. This protocol features an undivided cell setup with inexpensive carbon-based electrodes and exhibits a broad substrate scope and scalability in both flow and batch reactors. The use of this method in challenging contexts is
