TL;DR: By visualizing the electrochemical reduction of oxygen (hydrogen peroxide generation) at high resolution along pristine (defect-free) regions of individual single-walled carbon nanotubes, it is shown that there is significant activity comparable to that of standard gold electrocatalysts.

TL;DR: These studies provide movies of spatial variations of electrochemical fluxes as a function of potential and a platform for the further development of high speed scanning with other electrochemical imaging techniques.

TL;DR: Bias modulated (BM)-SICM is compared to conventional SICM imaging through measurements of substrates with distinct topographical features and yields equivalent results, and BM-SicM with both amplitude and phase feedback is used for topographical imaging of subtle etch features in a calcite crystal surface.

TL;DR: The trapping of photoexcited holes in the P3HT phase was found to contribute to the increased recombination rate and the results suggest that promising ways of improving the efficiency of bulk heterojunction solar cells may be reducing the charge trapping both at and near the P 3HT:PCBM interface, as well as improving the Efficiency of charge extraction at contacts.

TL;DR: The fabrication and use of a multifunctional electrochemical probe incorporating two independent carbon working electrodes and two electrolyte-filled barrels, equipped with quasi-reference counter electrodes (QRCEs), in the end of a tapered micrometer-scale pipet is described, demonstrating the utility of the technique.
