Velocity tuning of friction with two trapped atoms [PDF]

, 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

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

Superlubric sliding ferroelectricity

Applied 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 ...

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.

Nanoscale Frictional Properties of Nickel with one-dimensional and two-dimensional materials [PDF]

, 2016
When looking at the nanoscale, material interface interactions have been observed to exhibit particularly interesting properties. Our research looks into various combinations of carbyne and graphene atop a nickel block to look into the interface friction

Phonons in Twisted Transition Metal Dichalcogenide Bilayers ("Twistnonics"): Ultra-soft Phasons, and a transition from Superlubric to Pinned Phase

, 2019
The tunability of the interlayer coupling by twisting one layer with respect to another layer of two-dimensional materials provides a unique way to manipulate the phonons and related properties.

Bending modes, elastic constants and mechanical stability of graphitic systems [PDF]

, 2010
The thermodynamic and mechanical properties of graphitic systems are strongly dependent on the shear elastic constant C44. Using state-of-the-art density functional calculations, we provide the first complete determination of their elastic constants and ...

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 ...

Interlayer shear strength of single crystalline graphite

, 2012
Reported values (0.2 MPa ~ 7.0 GPa) of the interlayer shear strength (ISS) of graphite are very dispersed. The main challenge to obtain a reliable value of ISS is the lack of precise experimental methods.
