How confocal Raman microscopy helps dig into the details of glass corrosion
Ryan De Vooght-Johnson | | Quick Read
Thorsten Geisler-Wierwille of the University of Bonn, Germany, is using fluid-cell Raman spectroscopy to explore silicate glass corrosion by aqueous solutions – with potential implications for the storage of nuclear waste in glass form (1). Here, he tells us more.
What prompted your research?
The idea for the in situ Raman spectroscopy study of solid–solid replacement reactions in aqueous solutions hatched in my brain 15 years ago! Five years later, I raised funding for a Raman spectrometer to dedicate to long-term measurements. PhD student Christoph Lenting and I started to develop the analytical method, enabling us to obtain the first real-time spatially resolved in situ data on glass corrosion.
