Insight into macroscale superlubricity of polyol aqueous solution induced by protic ionic liquid
Friction, 2022 Currently, macroscale liquid superlubricity remains limited to low applied loads and typical ceramic friction pairs. In this study, a robust macroscale superlubricity with a coefficient of friction (COF) of approximately 0.006 is realized at the bearing ...

Harnessing big data to rethink land heterogeneity in Earth system models [PDF]
Hydrology and Earth System Sciences, 2018 The continual growth in the availability, detail, and wealth of environmental data provides an invaluable asset to improve the characterization of land heterogeneity in Earth system models – a persistent challenge in macroscale models. However, due to

Functionalized graphene-oxide nanosheets with amino groups facilitate macroscale superlubricity
Friction, 2022 Graphene-oxide (GO) has been recognized as an excellent lubrication material owing to its two-dimensional structure and weak interlayer interactions. However, the functional groups of GO that can contribute to anti-friction, anti-wear, and superlubricity

Homogenized Balance Equations for Nonlinear Poroelastic Composites
Applied Sciences, 2021 Within this work, we upscale the equations that describe the pore-scale behaviour of nonlinear porous elastic composites, using the asymptotic homogenization technique in order to derive the macroscale effective governing equations. A porous hyperelastic
