On 15 November 2021, the UK Department of Business, Energy, and Industrial Strategy published the Guide for Notifiable Acquisitions under the National Security and Investment Act ("Guide"), which will come into effect on 4 January 2022. The Guide emphasizes that the National Security and Investment Act requires organizations to notify the government about acquisitions of entities involved in seventeen areas of the economy which are deemed as "sensitive,". More specifically, the Guide defines and expands on specific considerations for each of these areas of the economy and the situations that necessitate notifying the government ("Mandatory Notification"). While the Guide observes that the research and usage of advanced materials are quickly expanding in both defense and civilian sectors, its relevance to assist in the transformation of key industrial sectors and supporting key areas of high-value manufacturing are emphasized. In addition, while highlighting the substantial benefits that advanced materials provide to military capabilities, it is argued that the national security risk it poses is obvious. According to the Guide, the intersectional and dual-use character of advanced materials would also mean that developing technologies based on advanced materials would have defense and security applications and ramifications independent of the application or industry that enables them to emerge.
