GRADUATE STUDENTS NEEDED for
Nanoscale chemical analysis using scanning transmission X-ray Microscopy
GOAL: To develop improved methods of X-ray
microscopy and to apply them to a variety of problems of
A) in situ electrochemical STXM - initially investigating metal electro-deposition and stripping, but ultimate goal is oxygen reduction reaction of fuel cells and CO2 electroreduction
B) Optimization of energy materials aided by soft X-ray microscopy
C) 4D chemical analysis - spectrotomography with STXM and/or ptychography. This project is technique oriented. Itwould continue the research begun by Juan Wu (PhD, 2018). Use of the new CLS cryo-STXM and improvements to acquisition, data analysis and presentation would be the focus.
NATURE of STUDIES: You will make X-ray microscopy measurements
at the Canadian Light Source (Saskatoon, SK) assisted by
others of the McMaster X-ray microscopy
team. Depending on your interests and skills, you will
be focused on a specific scientific problem, or you might
assist with the development of a new instrument or in situ
device. At McMaster you will analyze data, prepare samples,
and help develop analytical software.
SKILLS ACQUIRED: Working in a group environment; knowledge of core excitation spectroscopy (NEXAFS); polymer microstructure; analytical microscopy; synchrotron radiation; programming (C++, LabView, IDL), experiment design and execution.
SPECIAL BENEFITS: travel (financially supported); close collaboration with industrial scientists ( Ballard, Great Wall Motors, etc). Expertise with synchrotron radiation instrumentation.
