Macroscale Superlubricity Composites with Self‐Healing Functions
Advanced Functional MaterialsAbstract Achieving macroscale superlubricity with self‐healing functions in materials is pivotal to diminishing friction and prolonging the service life in mechanical engineering, yet challenges remain in intricate design and the fundamental trade‐off between these two functions. Here, oil (polyalphaolefin (PAO) and organic molybdenum

A dual-responsive microemulsion with macroscale superlubricity and largely switchable friction
Materials HorizonsA dual-responsive microemulsion capable of providing macroscale superlubrication in a broad temperature range and switching its coefficient of friction by ∼25 fold is reported. It also shows ultrahigh colloidal stability and anti-freezing properties.

Macroscale Superlubricity Enabled By Ensembles of Graphene on Diamond Nanoscrolls
ECS Meeting Abstracts, 2016The power of modern supercomputers together with the availability of highly scalable atomistic simulation codes have begun to revolutionize the modeling and computational analysis of materials. An enticing illustration of the same comes from our recent work where large-scale molecular dynamics (MD) simulations performed on Argonne’s supercomputer Mira ...

Friction and wear decrease the efficiency and lifetimes of mechanical devices. Solving this problem will potentially lead to a significant reduction in global energy consumption. We show that multilayer polyethylenimine/graphene oxide thin films, prepared via a highly scalable layer-by-layer (LbL) deposition technique, can be used as solid lubricants ...

Macroscale Superlubricity of Gellan Gum-Based Hydrogel Enhanced with Hydrated Ions
LangmuirOcular lubrication is a critical component of the biological lubrication system. Factors such as tear film instability and corneal epithelial damage can lead to increased friction on the ocular surface during blinking, which negatively impacts quality of life and results in economic burden. Eye drops are commonly used therapeutic purposes.

Friction. Macroscale superlubricity enabled by graphene nanoscroll formation.
Science (New York, N.Y.), 2015Friction and wear remain as the primary modes of mechanical energy dissipation in moving mechanical assemblies; thus, it is desirable to minimize friction in a number of applications. We demonstrate that superlubricity can be realized at engineering scale when graphene is used in combination with nanodiamond particles and diamondlike carbon (DLC ...
