Dislocated layered materials are fundamentally different to their non-dislocated equivalent. For example, screw dislocations in multiple graphene layers convert them into a single continuous helical sheet, allowing c-axis thermal and electrical conduction; both edge and screw dislocations block interlayer shear, normally considered universal between graphene layers. Non-basal dislocations in layered materials are common but despite this, due to their structural complexity, there are very few studies to date in the literature. Using the latest modelling tools, such as machine-learning carbon potentials (ASE and GAP-20U) we will explore prismatic edge dislocations and screw dislocations in nanoscale layered carbons, supported by AFM and Raman studies, synchrotron and electron microscopy. Our *scientific goal* is to explore and expand dislocation theory for layered 2D-materials, understand dislocation core structures, migration, and interaction with impurities such as water (pipe diffusion and hypersonic flow), as well as metals and halogens (dislocation mediated intercalation processes and formation of staging compounds). We will understand and explore dislocation formation mechanisms using irradiation and flash thermolysis. Our *technological goals* are to explore poorly understood technological processes in 2D-nanocarbons such as superlubrication in the context of dislocations, and the potentially crucial role of dislocations in intercalation, aiming to guide dislocation design in graphite battery electrodes for high-speed metal-ion intercalation and deintercalation. We will develop and optimise dislocation engineering in nanocarbons through irradiation and flash thermolysis. Our team consists of three partners in Nantes, Bordeaux and Lyon, with three overseas associates in UK, Spain and Australia, all of whom are well-known international experts in carbon defect physics and chemistry.
