Journal Article
Morton, J. A., Kaur, A., Khavari, M., Tyurnina, A. V., Priyadarshi, A., Eskin, D. G., …Tzanakis, I. (2023). An eco-friendly solution for liquid phase exfoliation of graphite under optimised ultrasonication conditions. Carbon, 204, 434-446. https://doi.org/10.1016/j.carbon.2022.12.070

Ultrasonic assisted liquid phase exfoliation (ULPE) is a promising method for the large scale production of 2D materials. Currently, toxic solvents such as N-Methyl-2-pyrrolidone (NMP) are commonly used for the production of graphene. In this paper f...
