Observation of Robust Macroscale Structural Superlubricity

Physical Review Letters
Structural superlubricity (SSL) promises nearly frictionless and wearless sliding but has until now been considered a special and extreme interfacial phenomenon limited to micro- and nanoscale contacts. Here, we demonstrate robust macroscale SSL within a single submillimeter graphite contact.

Achieving Macroscale Liquid Superlubricity Using Lubricant Mixtures of Glycerol and Diols [PDF]

, 2021
Abstract BackgroundWe aimed to assess a serological biopsy using five stomach-specific circulating biomarkers pepsinogen I (PGI), PGII, PGI/II ratio, anti- Helicobacter pylori (H. pylori) antibody, and gastrin-17 (G-17) for identifying high-risk individuals and predicting risk of developing gastric cancer (GC).ResultsIn the cross-sectional ...

Shear‐Induced Emergence of Aromatic Superlow‐Friction Interfaces in Amorphous Carbon: Triggering Chemical Impurities and Atomic‐Scale Mechanisms

Advanced Science, Volume 13, Issue 43, 3 August 2026.
High‐throughput quantum‐mechanical simulations reveal that amorphous carbon undergoes shear‐driven structural transformation into aromatic, graphene‐like interfaces. This mechanochemical process is governed by dopant chemistry: dopants with valency less than four promote the emergence of superlow‐friction amorphous graphene, whereas tetra‐valent ...

A Survey of Interlayer Interaction Models for Graphene and Other 2D Materials

Advanced Materials Interfaces, Volume 13, Issue 13, 7 July 2026.
Van der Waals interactions arising from electronic polarization at atomically close interfaces generate corrugated interlayer energy landscapes that govern normal and tangential tractions. This review presents an overview of quantum, atomistic, analytical, and continuum modeling approaches, highlighting their roles across length scales in capturing ...

Structural Superlubricity of Two-Dimensional Materials: Mechanisms, Properties, Influencing Factors, and Applications

Lubricants
Structural superlubricity refers to the lubrication state in which the friction between two crystalline surfaces in incommensurate contact is nearly zero; this has become an important branch in recent tribological research. Two-dimensional (2D) materials

A Review of Black Phosphorus‐Based Materials: From Preparation Strategies to Characterization Techniques

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
The structure, properties, preparation methods, and characterization techniques of BP. As a typical 2D layered material, black phosphorus (BP) demonstrates exceptional promise in various fields, particularly in energy storage for alkali metal‐ion batteries. However, its distinctive structure and properties, together with the compositional complexity of

Macroscale superlubricity enabled by rationally designed MoS2-based superlattice films [PDF]

, 2022
Abstract Although superlubricity is highly desirable for many engineering applications, its implementation has so far been seriously restricted due to limitations in contact size, environmental adaptability and life time. By designing superlattice films with alternating molybdenum disulfide (MoS2) and tungsten carbide (WC) layers, we show that ...

Macroscale Superlubricity in Water-Based Systems on Electroless Ni–P Coatings via P-Content Optimization and Tribofilm Control

Lubricants
Electroless Ni–P coatings are widely used for corrosion and wear protection, yet their ability to deliver water-based superlubricity and the role of phosphorus content remain insufficiently understood. Here, electroless Ni–P coatings with four P contents
