Advanced Functional Materials
Adding additives (e.g., carbon dots, CDs) to liquid lubricants is an effective method for enhancing their load‐bearing capacity and friction reduction. However, it is challenging to simultaneously impart high load‐bearing capacity and superlubricity for ...

Collective superlubricity of graphene flakes
Journal of Physics: Condensed Matter, 2016We investigate solid lubrication of graphene and graphene flakes using atomistic molecular-dynamics simulations. We find that graphene flakes yield lower friction than graphene as a result of a collective mechanism that emerges from the independent behaviour of the flakes.

Robust superlubricity by strain engineering
Nanoscale, 2019We demonstrate that robust superlubricity can be achieved via both biaxial and uniaxial tensile strains in a substrate using molecular dynamics simulation. Above a critical strain, the friction is no longer dependent on the relative orientation between the surfaces mainly due to the complete ...

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

Superlubricity in Gemini Hydrogels
Journal of Tribology, 2016Gemini hydrogels have repeatedly produced low friction under conditions generally not thought to be favorable to superlubricity: low sliding speeds, low contact pressures, macroscopic contact areas, and room temperature aqueous environments. A proposed explanation for this unique behavior is that thermal fluctuations at the interface are sufficient to ...

Unlocking Superlubricity: Ionic Liquids Meet Perfluorocarbons.
Nano letters (Print)Superlubricity, a state of near-zero friction, offers transformative potential for minimizing energy dissipation and mechanical wear. However, realizing stable superlubricity has remained challenging due to difficulties in sustaining reliable lubricant ...
