The CP kinetics result showed that the CP efficiency was very high for all the carbons, with them reaching the peak of magnetisation transfer around 1250-1000 us. The Carbon 6, both amorphous and crystalline, had especially high CP efficiency with maximum magnetisation reached at 250 us. The CP efficiency was relatively unchanged between the BC gel and the BC- hemicellulose composites. The change in temperature from 20 ° C to 5 ° C showed slight increase in CP efficiency and effect was relatively the same for all the hydrogels.
