UltraLubrico2D is a cutting-edge research project, also comprised of training and educational aspects, in the emerging field of superlubricity of 2D materials. Superlubricity is a kinetic state in which friction becomes negligible or even vanishes. The superlubric state can arise when incommensurate contacts are formed between periodic interfaces, such as 2D crystal materials. We have recently shown that superlubricity can manifest at the mm scale by removal of stick–slip instabilities through application of strain. UltraLubrico2D adopts the novel notion of manipulating superlubricity in 2D materials by mechanical straining.
The approach to be followed vastly differs from existing methodologies, based on non-invasive Raman-based techniques rather than AFM-based that affect the samples. We propose to use heterostructures of different 2D crystal combinations and, by applying strain, tune their frictional behavior and achieve superlubric behavior. 2D heterostructures are emerging as a most exciting class of 2D materials that seem to exhibit mechanical and electronic properties far richer than their constituents.
UltraLubrico2D combines theory and experiment for an in-depth treatment of the manifestation of superlubricity in 2D heterostructured materials, much required for both macroscopic and microscopic applications.
UltraLubrico2D is in line with the latest inclination of international funding programs to holistically train new scientists with combined Theoretical and Experimental skills; offers a wealth of fundamental contributions and high gains in several and seemingly unconnected areas of interest and to a wide audience.
