In situ observation of Cu electrodeposition and dissolution on Au(100) by high-speed atomic force microscopy

Nanoscale electrochemistry in a copper/aqueous/oil three-phase system: surface structure–activity-corrosion potential relationships

“…Thus, for the conditions of the present measurements, a third cathodic process that needs to be considered is the reduction complexation, as well as the intercalation of these ions within Cu adlayers during the deposition process, has been highlighted. [54][55][56][57] Constant current chronopotentiometry is a powerful approach for separating electrochemical processes that occur at similar potentials [e.g., Eqs. (1), (4) and (5)], 58 and this technique has recently been implemented in SECCM.…”

“…The important role of HSO 4 − /SO 4 2− through surface complexation, as well as the intercalation of these ions within Cu adlayers during the deposition process, has previously been reported. 54–57…”

“…52,79,80 Conversely, for the re-deposition process [i.e., Cu 2+ /Cu] sulphate complexation and intercalation is poised to play a major role. [54][55][56][57] The difference in mechanism may explain the different grain dependencies of the dissolution and deposition processes. dev.…”

Visualization of Electrochemical Cycling-Induced Dimension Change in LiMn2O4 Nanoparticles by High-Speed Atomic Force Microscopy

“…17 Yoshioka et al observed the Cu electrode position and dissolution on Au(100). 18 However, as is well known, no work has been reported for EC-HS-AFM to visualize the dimensional changes in the active electrode materials during the electrochemical reaction, especially at the single nanoparticle level.…”

Non-raster Methods in Scanning Probe Microscopy

“…The second category, faster controllers, seeks to do more with the existing hardware, applying approaches like adaptive proportional-integralderivative (Ando 2012), robust control (Helfrich et al 2009), and feedforward control (Clayton et al 2009). Combining techniques from these two categories has led to instruments that are orders of magnitude faster than older generations, opening up new avenues of research (Ando et al 2013;Heron et al 2014;Yoshioka et al 2018).…”
