College of Manchester and Nationwide Bodily Laboratory scientists have established a worldwide benchmark for verifying graphene’s single-atom thickness.
The benchmark was established utilizing high-resolution transmission electron microscopy (TEM). The work is reported within the journal 2D Supplies.
Graphene has the potential to revolutionize varied sectors, together with electrical automobiles and smartphones, however solely the place its high quality may be assured. The College of Manchester has spearheaded the biggest world research geared toward establishing a brand new worldwide commonplace for assessing the single-atom thickness of graphene.
The analysis group has created a reliable methodology that may function the muse for future industrial benchmarks. The research helps the event of a brand new ISO technical specification for graphene.
To include graphene and different 2D supplies into industrial functions, from lightweight automobiles to sports activities gear, contact screens, sensors, and electronics, you could know you’re working with the precise materials. This research units a worldwide benchmark that business can belief.

“Electron diffraction has lengthy been used to tell apart monolayer from few-layer graphene, nevertheless it’s typically utilized and not using a full remedy of uncertainties. By collaborating throughout 15 main labs. together with the unique pioneers, we’ve mapped the pitfalls and proven find out how to get dependable outcomes,” added Dr. Evan Tillotson.
We’ve designed this protocol so it really works in actual labs, not simply in specialist facilities. And for organizations with out TEM functionality, we are able to present measurements commercially by our partnership with the Royce Institute.

The outcomes are immediately integrated into the ISO/TS 21356-2 worldwide commonplace, which is at present in press and anticipated to be printed in 2026.
This work builds on the NPL Good Observe Information 145 ‘Characterization of the Construction of Graphene’ developed in partnership with the College of Manchester, and one in all NPL’s most downloaded guides.
