Superlubric sliding ferroelectricity

open access: yesApplied Physics Reviews
Structural superlubricity at incommensurate van der Waals interfaces leads to ultra-low friction coefficients. In this study, we try to apply a similar strategy to reduce the barrier of sliding ferroelectricity in van der Waals bilayers/multilayers with commensurate interfaces, since the writing speed in ferroelectric memories would be enhanced almost ...

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

open access: yesAdvanced 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

open access: yesAdvanced 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

Velocity tuning of friction with two trapped atoms [PDF]

open access: yes, 2015
Our ability to control friction remains modest, as our understanding of the underlying microscopic processes is incomplete. Atomic force experiments have provided a wealth of results on the dependence of nanofriction on structure velocity and temperature

Photoelectron superlubricity

open access: yes
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 ...

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

open access: yesMacromolecular 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.
