To jump or not to jump: Adhesion and viscous dissipation dictate the detachment of coalescing wall-attached bubbles
Çayan Demirkır, Rui Yang, Aleksandr Bashkatov +3
Bubble coalescence can promote bubble departure at much smaller sizes compared to buoyancy. This can critically enhance the efficiency of gas-evolving electrochemical processes, su…
Electrolyte spraying within H bubbles during water electrolysis
Aleksandr Bashkatov, Florian Bürkle, Çayan Demirkır +10
Electrolytically generated gas bubbles can significantly hamper the overall electrolysis efficiency. Therefore it is crucial to understand their dynamics in order to optimise water…
Performance enhancement of electrocatalytic hydrogen evolution through coalescence-induced bubble dynamics
Aleksandr Bashkatov, Sunghak Park, Çayan Demirkır +4
The evolution of electrogenerated gas bubbles during water electrolysis can significantly hamper the overall process efficiency. Promoting the departure of electrochemically genera…
Bubble size distribution and electrode coverage at porous nickel electrodes in a novel 3-electrode flow-through cell
Hannes Rox, Aleksandr Bashkatov, Xuegeng Yang +4
A novel 3-electrode cell type is introduced to run parametrical studies of H evolution in an alkaline electrolyte on porous electrodes. Electrochemical methods combined with a…
H bubble motion reversals during water electrolysis
Aleksandr Bashkatov, Alexander Babich, Syed Sahil Hossain +3
The dynamics of hydrogen bubbles produced by water electrolysis in an acidic electrolyte are studied using electrochemical and optical methods. A defined cyclic modulation of the e…
