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

Enhancing irradiation tolerance and inducing superlubricity in MoS2/W multilayer film exposed to atomic oxygen

Communications Materials
Molybdenum disulfide (MoS2) is a ubiquitous lubricant for use in outer space. Here, we present a MoS2/W nano-multilayer film engineered through precise structural optimization by fine-tuning sputtering parameters. This architecture, featuring alternating

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.

Thermal Transport Analysis of Hybrid (Al2O3 − Cu/H2O) Nanofluids With Inertial Drag and Cross‐Diffusion Under Convective Conditions Using the Mintsa–Gherasim Model: An Approach to Energy Research

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Purpose Energy transport is a crucial phenomenon across many engineering applications, and its importance continues to grow with increasing demand for physical and industrial problem‐solving. In order to examine the function of a hybrid nanofluid, two dissimilar types of metal and oxide nanoparticles (NPs) were added to the solvent water using the ...

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 ...

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

Origin of superlubricity of diamond-like carbon (DLC)

Friction
Hydrogenated diamond-like carbon (H-DLC) is typically produced as a coating or thin film through plasma-enhanced chemical vapor deposition (PE-CVD). H-DLC is relatively hard and well known to exhibit superlubricity.
