Interrogating the Electrochemical Interface Using Sum Frequency Generation Spectroscopy
SFG in tandem with electrochemical capacitance and CV measurements are used to study the effects of applied potential on the adsorption and orientation of PABA at a Ag(111) surface. The data indicates that PABA changes orientation in response to the charge on the electrode surface, orienting one …

Radiotracers and NMR as in situ probes at the electrochemical interface
The design and construction of a radiotracer instrument which allows the quantitative measurement of a radiolabeled adsorbate on atomically smooth electrodes for the first time is described. Using this instrument, the surface mobilities of three organic molecules (pyridine, formic acid, and acetic …

Numerical modeling of interface dynamics and transport phenomena in transport-limited electrolysis processes
Electrochemical reactions in materials and processes induce morphological instability on the cathode, which can lead to porous deposits or system failure. The growth of the protrusion is a complex phenomenon which involves chemical, electrical, and momentum driving forces in the system. Thus, it is …
