Biography

Sin-Yuen Chang is a postdoctoral research associate in the Industrial Liaison team at Diamond Light Source Ltd. joining in January 2016. Prior to this, she undertook PhD studies at The University of Manchester studying metal speciation and nucleation in complex functional liquid systems.

Her role at Diamond is to develop soft X-ray core level spectroscopies for applied research, in collaboration with Sven Schroeder's team. She supports industrial users of Diamond in the field of spectroscopy while also carrying out independent research.

Scientific Interests

Sin-Yuen is interested in both fundamental and applied research using X-ray absorption spectroscopy.

  • Soft X-ray spectroscopy covers important elements such as sulphur, phosphorus, carbon, oxygen, nitrogen and early transition metals. The technique is useful for revealing speciation of organic materials applicable for example in pharmaceutical, consumer product and food industries.
  • Development of automated data analysis software for high-throughput spectroscopies, e.g. quick-EXAFS, imaging spectroscopies and electron energy loss spectroscopy (EELS).
  • Fundamental aspects of XANES and EXAFS data analysis including revisiting commonly used oxidation state trends and studying Au reference spectra in detail (solvation effects, cis/trans isomerisation).
  • Through collaboration with the electrochemists at The University of Manchester and Kyoto University, Sin-Yuen performed mechanistic studies of metal nanoparticle synthesis at either electrified or non-electrified liquid-liquid interface, including studies of the prenucleation stage of transition metals nucleation.
  • Through collaboration with National Physics Laboratory studies of metal speciation in the context of nuclear fuel recycling are performed.
