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 ...

Linking interlayer twist angle to geometrical parameters of self-assembled folded graphene structures

, 2019
Thin adhesive films can be removed from substrates, torn, and folded in distinct geometries under external driving forces. In two-dimensional materials, however, these processes can be self-driven as shown in previous studies on folded twisted bilayer ...

Transient Formation of Single Layer Diamond During Friction Force Microscopy of SiC‐Supported Epitaxial Graphene

Advanced Materials Interfaces, Volume 12, Issue 22, November 22, 2025.
Friction force microscopy using diamond tips on epitaxial graphene supported by SiC(0001) shows a sharp friction increase. Silicon tips show similar behavior but at lower threshold forces. Atomistic simulations reveal three different friction regimes as normal pressure rises: graphene‐tip interfacial slip, graphene‐tip bonding, and a reversible ...

Study of Superlubricity

Hyomen Kagaku, 2003
Superlubricity, a phenomena of vanishing friction, has been studied theoretically and experimentally. It is theoretically shown that certain unique cases exist where friction force exactly vanishes when the atomic arrangements on the contacting surfaces satisfies the condition for the appearance of superlubricity.

Humidity‐Resistant Ultralow Friction in Diamond‐Like Carbon Coatings Enabled by Graphitic Nanodiamonds

Small Structures, Volume 6, Issue 10, October 2025.
The functionalization with graphitic nanodiamonds enhances friction reduction in diamond‐like carbon‐based interfaces. It promotes the formation of a stable, highly graphitic transfer layer, maintaining the core–shell arrangement. This study extends recent advances in superlubricity, providing insights into lubrication mechanisms in humid environments ...

Molecular Dynamics Study on Quartz‐Indenter Shape and Depth Effects in Epoxy Interfacial Mechanics

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 13, Page 2949-2964, September 2025.
ABSTRACT The interfacial mechanical behavior between epoxy and quartz at the microscale remains inadequately understood. The quartz‐indenter shape and indentation depth (hc) effect on epoxy interfacial mechanical behavior has been investigated through molecular dynamics (MD) simulation of nanoindentation and nanoscratching.
