Palladium Nanoparticle-Enabled Ultrathick Tribofilm with Unique Composition
ACS Applied Materials & Interfaces, 2018 There is a consensus that savings of 1.0-1.4% of a country's gross domestic product may be achieved through lubrication R&D. Recent studies have shown great potential for using surface-functionalized nanoparticles (NPs) as lubricant additives to enhance lubricating performance.

In-situ catalysis of green lubricants into graphitic carbon by iron single atoms to reduce friction and wear [PDF]
Nature CommunicationsReducing friction and wear in moving mechanical systems is essential for their intended functionality. This is currently accomplished by using a large variety of anti-friction and anti-wear additives, that usually contain sulfur and phosphorous both of ...

Boundary Friction of ZDDP Tribofilms [PDF]
Tribology Letters, 2020 AbstractThe frictional properties of ZDDP tribofilms at low entrainment speeds in boundary lubrication conditions have been studied in both rolling/sliding and pure sliding contacts. It has been found that the boundary friction coefficients of these tribofilms depend on the alkyl structure of the ZDDPs. For primary ZDDPs, those with linear alkyl chains

Synthesis of ultrathin two-dimensional metal-organic framework nanosheets for lubricant additives
Materials & Design, 2022 Two-dimension (2D) nano materials are diffusely employed as lubricant additives. In this paper, three kinds of ultrathin 2D metal-organic framework (MOF) nanosheets with different metal ions (Ni2+, Zn2+, and Cu2+) were successfully synthesized by ...
