•XRD Scans with peaks indicating presence of specific crystalline compounds<br />
•Gradual peaks in shaded regions indicate presence of stacked graphene sheets<br />
•Hump at ~28° indicates thickness of stacks<br />
•Hump at ~51° indicates lateral dimensions of sheets<br />
•Characteristics of graphene sheets affect multiple char properties – surface area, decay<br />
resistance, water retention etc.<br />
•Multiple smaller peaks likely indicate mineral ash compounds, including quartz and carbonate<br />
