Effect of lubricants on the rotational transmission between solid-state gears [PDF]
Beilstein Journal of Nanotechnology, 2022 Lubricants are widely used in macroscopic mechanical systems to reduce friction and wear. However, on the microscopic scale, it is not clear to what extent lubricants are beneficial. Therefore, in this study, we consider two diamond solid-state gears at the nanoscale immersed in different lubricant molecules and perform classical MD simulations to ...

Friction, 2023 Superlubricating materials can greatly reduce the energy consumed and economic losses by unnecessary friction. However, a long pre-running-in period is indispensable for achieving superlubricity; this leads to severe wear on the surface of friction pairs

Tribology of the lubricant quantized sliding state [PDF]
The Journal of Chemical Physics, 2009 In the framework of Langevin dynamics, we demonstrate clear evidence of the peculiar quantized sliding state, previously found in a simple one-dimensional boundary lubricated model [A. Vanossi et al., Phys. Rev. Lett. 97, 056101 (2006)], for a substantially less idealized two-dimensional description of a confined multilayer solid lubricant under shear.

Macro-superlubricity in sputtered MoS2-based films by decreasing edge pinning effect
Friction, 2023 To date, MoS2 can only be achieved at microscale. Edge pinning effect caused by structure defects is the most obvious barrier to expand the size of structural superlubricity to macroscale.

Journal of Advanced Ceramics, 2022 The high strength and toughness of natural materials are mainly determined by a combination of mechanisms operating at different length scales, which can be used as a strategy to reduce the intrinsic brittleness of ceramics. Inspired by the architectures

Synthesis of Imidazole-Based Deep Eutectic Solvents as Solid Lubricants: Lubricated State Transition
Materials, 2023 The controllable character of the melting point of deep eutectic solvents (DESs) makes it easy to realize lubricated state transitions and produce excellent lubricating properties during friction. In this work, a series of novel imidazole-based DESs were synthesized to present a room-temperature solid state by shifting its eutectic point.

Design of large-span stick-slip freely switchable hydrogels via dynamic multiscale contact synergy
Nature Communications, 2022 Switching between adhesive and non-adhesive states is important to design materials with on-demand adhesion properties but realizing reversible switching on large scale remains challenging.

Friction Regimes in the Lubricants Solid-State Regime [PDF]
, 1995 Friction measurements were performed in the lubricant's solid-state regime to study the transition from full-film lubrication, in which the separation is maintained by a solidified lubricant, to mixed lubrication. Special attention is paid to the influence of temperature (inlet viscosity) and roughness on this transition.
