Editorial: Electrochemistry Communications, 24, p.21-24, 2012.

Rezumat:

The development and characterisation of electrochemically generated hydrogen bubbles for gas evolution
kinetics and force spectroscopy are described. Bubbles have been grown at the platinised tip of a commercially
available atomic force microscopy (AFM) needle probe (exposed electrode radius rb300 nm) and monitored by
CCD camera. Results showconsistent bubble growth in galvanostatic conditions. The utility of the bubble probes
in AFM force spectroscopy is demonstrated.
