Description:About the seminar:\n\nNanoelectrochemical tools\, such as elect
 rochemical microscopes\, nanopore sensing\, and nanoelectrodes\, can addre
 ss questions that are inaccessible to macroscale techniques. They allow on
 e to measure faster processes and shorter-lived species\, assess spatial h
 eterogeneity of electrode surfaces\, and by measuring individual nanoscale
  entities (e.g.\, nanoparticles)\, assess heterogeneity in a population. T
 his has led to a deeper understanding of both electrochemical processes (e
 .g.\, electrocatalysis) and physical processes (e.g.\, nucleation).\n\nYet
  despite these advances\, key experiments from the macroscale electroanaly
 tical toolbox are presently inaccessible or infeasible at the nanoscale. F
 or example\, it is not feasible to characterize individual nanoentities or
  nanoscale regions with multiple solutions with a statistically relevant t
 hroughput. Yet\, changing the solution composition is a powerful and commo
 nly applied strategy with numerous applications. For example\, one might d
 ecipher a reaction mechanism by measuring at different pHs\, adding reacti
 on intermediates\, or inhibitors. Alternatively\, one might electrodeposit
  an electrocatalyst and then characterize it in a different solution\, stu
 dying how deposition parameters influence activity. Or more simply\, one m
 ight wish to perform a background measurement and then measure at differen
 t analyte concentrations to deliver background subtracted current-concentr
 ation responses. This talk will describe our efforts to address this limit
 ation through development of a species-switching scanning electrochemical 
 microscope capable of measuring single nanoscale regions and entities unde
 r multiple solution conditions.\n\nAbout the speaker:\n\nMartin Edwards is
  an assistant professor of analytical chemistry at the University of Arkan
 sas\, Fayetteville. His group’s research combines physical/analytical te
 chniques with mathematical modeling to understand and manipulate diverse m
 icro- and nanoscale phenomena. Using an approach that combines physical an
 d analytical measurements with modeling (mathematical/statistical/numerica
 l)\, he has tackled problems and answered questions in areas ranging from 
 single-molecule bioanalytical measurements\, through next-generation energ
 y-storage technologies\, nucleation\, and electrocatalysis. A constant thr
 ead throughout his research is the development of novel instrumentation\, 
 experiments\, and the frameworks for interpreting them. His work frequentl
 y involves the development or modification of scanned probe microscopes. H
 e was the 2020 recipient of the Royce Murray Young Investigator award from
  the Society of Electroanalytical Chemistry (SEAC). 4:00 pm
