Congrats to Samanali

Congratulations to Samanali on her publication “Artificially light-aged, black-dyed harakeke fibres: Understanding the correlations between chemical composition and fibre properties using vibrational spectroscopy and chemometrics” in Spectrochimca Acta B.  This work was part a longer term project which investigated harakeke fibres and the effects of dying and aging on them.  Samanali’s work shows how infrared spectroscopy can be used to understand the oxidation of the fibres themselves while Raman spectroscopy can be used to look at the degradation of the dyes that are often used.
