Empowering Innovation through Standardisation 

Dr. Jörg Radnik, a distinguished expert at the Bundesanstalt für Materialforschung und –prüfung (BAM), provides invaluable insights into the pivotal role of standardisation, particularly within the realm of 2D materials. In his role as standardisation leader for the GrapheneEU Coordination and Support Action, Radnik will guide the Graphene Flagship projects in standardisation matters and help them to take part in the standardisation decisions being made today which will impact the field for decades to come. 

Radnik, with a profound background steeped in decades of research in X-ray spectroscopy, catalysis and analytical methods, brings a wealth of experience to his current role at BAM's Division 6.1: Surface Analysis and Interfacial Chemistry. Since joining BAM in 2016, he has been a driving force behind advancements in analytical techniques, notably X-ray photoelectron spectroscopy (XPS) and has actively contributed to standardisation efforts, both domestically and on a global stage. 

The significance of standards in material development 

In a candid dialogue with Radnik, the paramount importance of standards in material development becomes abundantly clear. He articulates how uncertainties often shroud the characterisation of new materials, impeding their widespread adoption and commercialisation. Standards serve as beacons of clarity, providing a common language and framework for precisely defining materials, their properties and measurement protocols. This clarity not only fosters trust among stakeholders but also facilitates reproducibility and comparability, thereby laying the foundation for innovation and industrialisation. 

The influential reach of the Graphene Flagship 

Within the landscape of standardisation, Europe, spearheaded by initiatives like the Graphene Flagship, assumes a central role in shaping international standards for 2D materials. Radnik underscores the significant influence exerted by collaborative efforts within the Graphene Flagship in propelling standardisation forward. Through the initiation of standardisation projects and the proposal of consensus-based protocols, Europe endeavours to lead the charge in defining accepted standards, thereby solidifying its position as a nexus of innovation in the field. 

Navigating the path forward 

Despite notable strides, Radnik notes that substantial work remains to be done in comprehensively standardising 2D materials. While consensus on terminology and measurement protocols is beginning to emerge, the delineation of standards across the entire product chain remains a priority. Over the next two years, concerted effort will be directed towards establishing standards for chemical composition, defect characterisation, contamination control, morphology assessment and other crucial parameters. 

A contemplation on nanomaterials vs 2D materials 

A pertinent question arises regarding the classification of 2D materials within the broader realm of nanomaterials. Radnik acknowledges the prevailing classification but anticipates future deliberations on whether distinct standards for 2D materials are warranted. As the field evolves, collaborative discussions will be imperative to ensure a nuanced approach to standardisation, one that fosters innovation while upholding regulatory rigor and safety standards. 

Fostering trust through standardisation 

In his closing remarks, Radnik emphasises that standardisation transcends mere technical specifications; it is about instilling trust. By establishing robust standards, stakeholders are empowered with confidence in material quality and performance, while societal trust in the safety and reliability of emerging technologies is bolstered. This trust forms the bedrock for widespread acceptance and adoption of 2D materials in commercial products, thereby propelling innovation and economic growth. 

In conclusion 

As we navigate the frontier of materials science, standardisation emerges as a linchpin for progress. Jörg Radnik's insights serve as a guiding light, illuminating the critical role of standards in unlocking the full potential of 2D materials. Through collaborative endeavours, such as those championed by the Graphene Flagship, we can chart a course towards a future where clarity, reliability and trust reign supreme in the realm of materials development. As we embark on this journey, let us recognise the power of standardisation in the commercialisation of graphene, fostering collaboration, and promoting the use of graphene in new exciting products.
