Journal ArticleDOI
Scanning Electrochemical Cell Microscopy: A Versatile Technique for Nanoscale Electrochemistry and Functional Imaging
Neil Ebejer,Aleix G. Güell,Stanley C. S. Lai,Kim McKelvey,Michael E. Snowden,Patrick R. Unwin +5 more
TL;DR: The power of SECCM in resolving complex structure-activity problems is discussed and considerable new information on electrode processes is provided by referring to key example systems, including graphene, graphite, carbon nanotubes, nanoparticles, and conducting diamond.
Journal ArticleDOI
Scanning Electrochemical Cell Microscopy: Theory and Experiment for Quantitative High Resolution Spatially-Resolved Voltammetry and Simultaneous Ion-Conductance Measurements
Michael E. Snowden,Aleix G. Güell,Stanley C. S. Lai,Kim McKelvey,Neil Ebejer,Michael A. O’Connell,Alex W. Colburn,Patrick R. Unwin +7 more
TL;DR: It is shown that the dc current can be predicted for a fixed probe by solving the Nernst-Planck equation and that the ac response can be derived from this response, and both responses are shown to agree well with experiment.
Journal ArticleDOI
Nanoscale Electrochemistry of sp2 Carbon Materials: From Graphite and Graphene to Carbon Nanotubes
TL;DR: This Account advocates the use of emerging electrochemical imaging techniques and confined electrochemical cell formats that have considerable potential to reveal major new perspectives on the intrinsic electrochemical activity of carbon materials, with unprecedented detail and spatial resolution.
Journal ArticleDOI
Structural Correlations in Heterogeneous Electron Transfer at Monolayer and Multilayer Graphene Electrodes
TL;DR: It is established that the rate of heterogeneous ET at graphene increases systematically with the number of graphene layers, and it is shown that the stacking in multilayers also has a subtle influence on ET kinetics.
Journal ArticleDOI
Lithographically patterned nanowire electrodeposition: a method for patterning electrically continuous metal nanowires on dielectrics.
Chenxiang Xiang,Sheng-Chin Kung,David K. Taggart,Fan Yang,Michael A. Thompson,Aleix G. Güell,Yongan Yang,Reginald M. Penner +7 more
TL;DR: The temperature-dependent resistance of 100 microm sections of Au and Pd wires is measured in order to estimate an electrical grain size for comparison with measurements by X-ray diffraction and transmission electron microscopy.
