A new standard to help verify graphene materials

The National Physical Laboratory (NPL), in collaboration with international partners, have developed an ISO/IEC standard, ISO/TS 21356-1:2021, for measuring the structural properties of graphene, typically sold as powders or in a liquid dispersion. The ISO/IEC standard helps the supply...

New machine-learning method could characterize graphene materials quickly and efficiently

Monash University scientists have created an innovative method to help industry identify high quality graphene cheaper, faster and more accurately than current methods. The researchers used the data set of an optical microscope to develop a machine-learning algorithm that...

Graphene takes a step towards enabling end-users to maintain their own resistance standards

Recent research by NPL, Oxford Instruments, Chalmers University and Graphensic has enabled the quantum Hall effect to be realized at both lower magnetic fields and higher temperatures, whilst still retaining part per billion accuracies. The long-term collaboration between NPL,...

ISO publishes standard on matrix of properties and measurement techniques for graphene

The International Organization for Standardization (ISO) has published standard ISO/TR 19733:2019, “Nanotechnologies — Matrix of properties and measurement techniques for graphene and related two-dimensional (2D) materials”. ISO states that since graphene was discovered in 2004, it has become...

Talking graphene standardization with NPL’s Andrew J Pollard

In November 2017, after years of work, the International Organization for Standardization (ISO) released its first graphene standard, the ISO/TS 80004-13:2017. The effort was led by the UK's National Physical Laboratory (NPL).We recently discussed this interesting and important development...
