Breakthrough in Electrochemical Bubble Production on Nanoelectrodes

Monday, 08 April 2013

A team of researchers from The University of Queensland (UQ) and the Technische Universität Braunschweig and the Helmholtz Centre for Environmental Research in Germany are entering unchartered territory in their study to improve knowledge of bubbles stability and their interactions with matter.

The team have unveiled a method to produce colloid-size bubbles at the tip of a needle probe usually employed in Atomic Force Microscopy (AFM) which are crucial to applications such as wastewater treatment and coal flotation, medical imaging and diagnostics.

Dr Bogdan Donose from the AWMC along with Dr Elena Taran from the Australian National Fabrication Facility Queensland Node (ANFF-Q) and Australian Institute for Bioengineering and Nanotechnology (AIBN) has spent the past decade working on AFM and applications of colloid and surface science. The German member of the team, Dr Falk Harnisch is a reputed bio-electrochemist, who recently has become a group leader in Helmholtz Centre for Environmental Research, Leipzig.

“Developing electroflotation strategies based on electrochemically generated microbubbles would help optimise wastewater treatment, will help getting rid of oil spills and will improve the recovery of useful minerals” Dr Donose said.
