Robert Lazenby


Research Assistant in the Warwick Electrochemistry & Interfaces Group (WEIG)


PROFILE

I obtained an MChem in Chemistry with Industrial Training in 2010, and joined WEIG in the same year. I spent one year working for GlaxoSmithKline, in the Analytical Chemistry department, on a project investigating the use of charged aerosol detection for universal quantitative detection, without the need for analyte-specific calibrations. My final year master's project was spent investigating room temperature ionic liquids as electrolytes for carbon-based electrodes.



PHD RESEARCH

 

My PhD research was focussed on understanding electrochemical reactions on sp2 carbon materials, using high resolution electrochemical imaging techniques to visualize the reactions on such materials. To this end, I utilized a wide range of imaging techniques, for example intermittent contact-scanning electrochemical micoscopy (IC-SECM), developed by the group at Warwick, and scanning ion conductance microscopy (SICM).

The work has developed IC-SECM by pushing the resolution of the technique to the nanoscale, and introducing a hopping-mode scan, which provides a much greater volume of information as compared to routine SECM technques.

My joint supervisors were Prof. Patrick R. Unwin and Prof. Julie V. MacPherson.

This work was funded by the EPSRC (Engineering and Physical Sciences Research Council).
