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

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

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