About this collection
Guest Edited by Professor James D Batteas, Texas A&M University, USA
Since exploding onto the scene, graphene has held the spotlight when it comes to 2D materials, but it is far from the only 2D material of merit, and research has expanded to a range of other materials that have been receiving attention for their ingenious functionality both individually, and as part of composites and heterostructures. The papers in this collection (highlighting work from 2016 and 2017) illustrate the impact that 2D materials and heterostructures can have on fields such as microelectronics, energy generation and storage, environmental pollutant removal, superconductivity, HER, and more, and RSC Advances is proud to be at the forefront to share this information with its readers.
