1 25m Grant To Advance Control Of 2d Materials Cornell Engineering Berman: “toward macroscale superlubricity with 2d materials“. prof. marian: "2d mxenes to tailor friction and wear from machine elements and biomedical applications to energy harvesting". In this review, we outline basic mechanisms for frictional energy dissipation during sliding of two surfaces against each other, and the procedures for manipulating friction and wear by introducing 2d materials at the tribological interface.
2d Materials Alchetron The Free Social Encyclopedia Two dimensional (2d) materials have demonstrated unique friction and antiwear properties unmatched by their bulk (3d) counterparts. a relatively new, large and quickly growing family of two dimensional early transition metal carbides and nitrides (mxenes) present a great potential in different applications. Firstly, superlubricious state for heterogeneous interface between 2d materials with large lattice mismatch has been predicted. the superlubricity has been attributed to the negligible interfacial charge density fluctuation during sliding, and has been realized at both nanoscale and microscale. The results reveal that macroscale structural superlubricity of 2d materials is highly dependent on the dynamic evolution of tribolayers nanostructures, as well as the adsorption and tribochemical behaviors governed by extreme pressure. In this review, we summarize the beneficial properties of layered 2d materials that enable the control of their tribological behavior and make them excellent candidates for efficient friction and wear reduction in dry running and boundary lubricated machine components.
