High-Frequency-Induced Cathodic Breakdown during Plasma Electrolytic Oxidation [PDF]

open access: yes, 2017
The present communication shows the possibility of observing microdischarges under cathodic polarization during plasma electrolytic oxidation at high frequency. Cathodic microdischarges can ignite beyond a threshold frequency found close to 2 kHz.

First direct evidence of N-heterocyclic carbene in BMIm acetate ionic liquid. An electrochemical and chemical study on the role of temperature [PDF]

open access: yes, 2017
Cyclic voltammetry provides the first direct evidence of N-­heterocyclic carbene (NHC) presence in neat 1-‐butyl-­3-­methylimidazolium acetate ionic liquid (BMImAcO) at 120°C. The NHC existence, proved by its oxidation current in cyclic voltammetry, was
