X-ray diffractograms (XRD) and solid-state nuclear magnetic resonance (NMR) spectra for unrefined and refined pretreated sugarcane bagasse after PFI and disc refining at different intensity levels. a The normalized XRD and calculated crystallinity index. b The normalized solid-state NMR spectra. XRD and NMR results are based on a single measurement
