NMR proton relaxation for measuring the properties of graphene nanoplatelets

Sofia Marchesini, Research Scientist at the National Physical Laboratory, demonstrates nuclear magnetic resonance proton relaxation for the characterisation of graphene dispersions at the Graphene Engineering Innovation Centre at The University of Manchester.
The device measures relative changes in specific surface area in graphene dispersions and hence the degree of exfoliation of graphene flakes within the dispersion. The advantages of this instrument are the very short measurement time and that graphene can be measured directly in a liquid dispersion without the need for any sample preparation.
Thus, this instrument can be used as a rapid quality control tool and could be integrated into a graphene manufacturing facility. More information can be found at: doi.org/10.1039/D1NR03361A and doi.org/10.1039/D0NR08937K

Hi Sofia..our Company is presently working with Manchester GEIC on establishing Graphene Quantum Dots in lubricants..results are not conclusive and after watching your recent laboratory microscopy testing together with its data calibrations if you would be available to discuss our project to try and assist in understanding the testing limits if this is the case..?Appreciate if you could contact me when convenient.
Regards.
Alan Barrett
