Tunable macroscale structural superlubricity in two-layer graphene via strain engineering

Nature Communications, 2020
Superlubricity in macro-scale graphitic samples is hampered by commensurate stacking domains that prevent facile sliding between adjacent graphene layers.

The Promise of Solid Lubricants for a Sustainable Future

Advanced Materials, Volume 38, Issue 8, 6 February 2026.
Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?

Adhesive Tape‐Inspired Polymer Coatings Enable Record‐Stable Zinc Anodes for High‐Rate Aqueous Batteries

Advanced Science, Volume 13, Issue 10, 18 February 2026.
An adhesive tape–inspired anode stabilization strategy is proposed by grafting poly(methyl methacrylate) onto natural rubber. The resulting copolymer coating exhibits elasticity, adhesion, and ion‐selective nanodomains, which lower Zn2+ desolvation barriers, guide deposition to the stable (002) facet, and ensure intimate interfacial contact, delivering

Approaching the Monolayer Limit of Carbon Layers by Pyrolysis of Polymer Films

Advanced Electronic Materials, Volume 12, Issue 3, 4 February 2026.
Wafer‐scale functional devices based on pyrolyzed photoresist films are synthesized directly on target substrates without catalysts or transfer steps, with channels reaching the monolayer limit (0.34 nm). X‐ray photoelectron spectroscopy confirms predominant sp2 character, Raman spectroscopy reveals evolving nanocrystallinity, and transmission electron

In Situ Synthesized Glycerol‐Releasing Nanocarriers Unlock Superlubricity in Oil‐Based Lubricants

Macromolecular Materials and Engineering, Volume 311, Issue 2, February 2026.
This study presents an in situ synthesis of glycerol‐based nanocarriers in hydrophobic lubricant oils via inverse miniemulsion polymerization. Encapsulating glycerol within a glycerol‐based polyurethane shell resolves miscibility issues between glycerol and the hydrophobic base oil, yielding novel nanoadditives with tunable glycerol loading.

Investigation of the mechanisms for stable superlubricity of poly(vinylphosphonic acid) (PVPA) coatings affected by lubricant

Friction, 2016
The stability of the tribological properties of polymer coatings is vital to ensure their long term use. The superlubricity of the poly(vinylphosphonic acid) (PVPA)-modified Ti6Al4V/polytetrafluoroethylene (PTFE) interface can be obtained when lubricated

Photoelectron superlubricity

Superlubricity, a state where friction between two contact surfaces is nearly zero, has a great potential to revolutionize various mechanical systems by significantly reducing energy dissipation and enhancing efficiency. It can be realized either by structural incommensurate contact between crystalline surfaces or by creating highly passive interfaces ...
