Curvature‐Tuned Friction at Electrified Ionic Liquid Interfaces

Advanced Functional Materials, EarlyView.
Graphene curvature plays a key role in friction electrotunability at single‐asperity contacts lubricated by ionic liquids. A 9 nm radius yields stronger tunability than larger radii, with distinct friction coefficients at low and high loads indicating a shift in the slippage plane.

Proposal of Biomimetic Tribological System to Control Friction Behavior under Boundary Lubrication by Applying 3D Metal Printing Process

Tribology Online, 2018
A new concept was proposed as biomimetic tribological (BMT) system by using three-dimensional (3D) printing process. The BMT had a lubricant supply path (LSP) beneath the sliding surface.

Viable Use of Tire Pyrolysis Oil as an Additive to Conventional Motor Oil: A Tribological and Physical Study

Lubricants
Stockpiled end-of-life tires (ELTs) pose a serious environmental concern. In the current investigation, ELT pyrolysis oil (i.e., pyro-oil) was studied as a potential additive to conventional motor oil.

Noise influence on solid-liquid transition of ultrathin lubricant film

, 2004
The melting of ultrathin lubricant film by friction between atomically flat surfaces is studied. The additive noises of the elastic shear stress and strain, and the temperature are introduced for building a phase diagram with the domains of sliding ...
