TL;DR: In this paper, the first observation of localized electropolymerization of pyrrole and aniline on highly oriented pyrolytic graphite (HOPG) substrates under atomic force microscopy (AFM) tip−...

TL;DR: In this paper, the authors investigated the diffusion coupled oscillatory behavior of the Au|HCI system in the presence of substrate feedback in the scanning electrochemical microscopic (SECM) system and showed that the amplitude of current oscillation can be increased significantly with a slight decrease in the oscillation frequency when the Pt substrate is positioned close to the small Au oscillating electrode.

TL;DR: In this article, the H-terminated n -Si(111) surface was found to be etched locally under the STM tip in the dilute HF solution by applying a given positive potential to the tip while keeping the silicon electrode potential near its flatband potential, at which the oxidative etching of silicon is not expected to occur in the absence of light.

TL;DR: In this article, the UV radiation-induced coalescence reaction of C 60 was in situ monitored by Raman spectroscopy for the first time, and the process was also characterized by STM and laser desorption mass spectrometry.

TL;DR: In this paper, a method of destroying or avoiding the historic effect of the substrate was developed, which provides a new way of performing a large number of electrochemical measurements without mechanical polishing and manual interference, and therefore facilitates further more detailed studies of a system which requires continuous and automatic I-t transient measurements of statistical meaning.
