Conspectus The widespread adoption of graphene in commercial technology has long been hindered by the difficulty of producing high-quality material at scale and patterning it into functional circuits without complex, multistep lithography. This Account explores our laboratory’s solution to this challenge: the photothermal transformation of solution-processable graphene oxide (GO) into laser-scribed graphene (LSG).

Abstract Diesel trains play a vital role in the UK’s rail passenger transport. Despite efforts to expand electrification, over 10% of the UK’s rail routes will remain non-electrified. To reduce emissions and phase out diesel trains by 2040, the UK rail network is actively exploring alternative fuels. This paper presents a comprehensive technical, economic, and environmental analysis of converting diesel trains to hydrogen-powered trains using a hydrogen combustion engine for the first time.
