Alternating current-bipolar electrochemistry
Electrochemistry Communications, 2017 Abstract Rotation of a bipolar electrode in a constant electric field between feeder electrodes causes an alternating bipolar current at an AC frequency that depends on the rotation rate. The corresponding oscillation of the feeder current is evaluated by means of a lock-in amplifier.

Pit growth kinetics of additively manufactured MoNi over-alloyed type 316L stainless steel
Journal of Materials Research and Technology, 2023 The microstructure and corrosion performance of wrought, laser powder bed fusion (LPBF), and MoNi over-alloyed LPBF type 316L stainless steel is compared. Adding Mo and Ni to LPBF 316L stainless steel resulted in ẟ-ferrite.

Recent Advances in Bipolar Electrochemistry with Conducting Polymers
ChemElectroChem, 2021 AbstractConducting polymers have been extensively studied due to their potential applications ranging from sensing to energy storage, and environmental remediation. They can be easily generated by electrosynthesis and have also very interesting electrochemical features, which have been mostly examined with classic electrochemical approaches.

Closed bipolar electrodes for spatial separation of H2 and O2 evolution during water electrolysis and the development of high-voltage fuel cells [PDF]
, 2017 Electrolytic water splitting could potentially provide clean H2 for a future ‘Hydrogen Economy.’ However, as H2 and O2 are produced in close proximity to each other in water electrolysers, mixing of the gases can occur during electrolysis, with ...

Corrosion electrochemistry with a segmented array bipolar electrode
Electrochimica Acta, 2021 Bipolar electrochemistry was applied to determine the full spectrum of anodic-to-cathodic polarisation behaviour of stainless steel. The potential and current distributions at the sample surface were determined using a segmented array bipolar electrode (BPE).

Bioelectrochemistry of Cytochrome c in a closed bipolar electrochemical cell
Electrochemistry Communications, 2019 The reversible oxidation and reduction of Cytochrome c (Cyt c) is demonstrated with a closed bipolar electrochemical cell (CBPEC). Herein, a 4-electrode configuration was studied with the opposite poles of the bipolar electrode resting in separate ...
