Sharp diffraction peak
WebbXRD pattern is a commonly used tool for separating the compositions and crystallinity of as-prepared graphene materials. Fig. 4.1 shows the XRD patterns of reduced graphene oxide-cellulose nanocrystals-manganese dioxide (rGO–CNC–MnO 2) obtained by in-situ hydrothermal synthesis.Based on the results, it is clear that several sharp diffraction … WebbA peak occurs because the interaction cross section increases as the charged particle's energy decreases. Energy lost by charged particles is inversely proportional to the …
