Scanning Electrochemical Microscopy

We are sorry, this position has been filled.

This project will be based around advancing a powerful chemical imaging technique called scanning electrochemical microscopy (SECM). SECM uses scanning microelectrodes to locally interrogate the local chemical and physical properties of a surface with high spatial resolution, allowing researchers to develop structure-property relationships at the microscale within the electrochemical environment. This collaborative project will be based around the use of a one-of-its kind SECM microscope that is capable of increasing imaging rates by at least an order of magnitude compared to conventional SECM microscopes. Research tasks will include making microelectrodes, operating the microscope, and carrying out in situ colorimetric imaging tests to visualize diffusion boundary layer plumes associated with “hot spots” on electrode surfaces. This project will require previous coursework in electrochemistry.
