Tribological Properties of Ionic Liquids

open access: yes, 2013
An ionic liquid is a liquid salt consisting of anions and cations. Since Wilkes [1] synthesized a low melting point ionic liquid that is stable in air in 1992, there has been active fundamen‐ tal research and engineering development directed at applications.

Next Generation Smart Implant Surfaces: Engineering Multifunctional Antimicrobial, Immunomodulatory and Regenerative Interfaces

open access: yesJournal of Periodontal Research, EarlyView.
Natural‐inspired nano‐textured implant surfaces can be functionalised to modulate macrophage polarisation and local immune responses. This bioactive control promotes improved tissue integration and healing outcomes. ABSTRACT Dental implants rely on a stable and functional interface between the implant surface, surrounding tissues, and the oral ...

Structural characterization and optimum machining parameters of jute/carbon fibre hybrid reinforced epoxy composite laminates

open access: yesPolymer International, Volume 75, Issue 9, Page 804-817, September 2026.
Hybrid jute/carbon epoxy laminates have better mechanical performance and less drilling damage by the use of optimized stacking sequence and machining parameters. Abstract Three composite laminate systems were produced using the standard hand lay‐up method: jute‐fibre‐reinforced polymer (JFRP), carbon‐fibre‐reinforced polymer (CFRP) and a hybrid of the

Dynamic Characteristics Analysis of a Large Wind Turbine Gearbox Supported by Journal Bearings Under Different Lubrication States

open access: yesWind Energy, Volume 29, Issue 9, September 2026.
ABSTRACT Due to their superior load density, planetary gear journal bearings (PGJB) are progressively replacing rolling element bearings in wind turbine gearboxes; therefore, accurately revealing the dynamic characteristics of drivetrains supported by these bearings under variable operating conditions is crucial for ensuring operational reliability ...

Electrified Damage in Motion Systems

open access: yesAdvanced Engineering Materials, Volume 28, Issue 15, 5 August 2026.
The electrified damage in motion systems is a fundamental framework presenting the degradation pathway arising from the coupling of electrical energy transport with mechanical contact and interfacial chemistry. The framework positions electrified damage as a distinct degradation regime with unique characteristic surface morphologies and failures of ...

Influence of Carbon Nanoparticles on Electrically Induced Wear of Grease‐Lubricated Steels

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 15, 4 August 2026.
When an electric current enters a pair of rubbing surfaces, enormous damage takes place. In this research, how such damage occurs in the presence of protective grease and the mitigation with added carbon nanoparticles, were investigated. It was discovered that those particles regulate transport and interfacial electrical stability of the grease ...

Effect of Si addition on the microstructure and tribological properties of FeCrNi medium entropy alloy

open access: yesJournal of Materials Research and Technology
FeCrNi medium-entropy alloys (MEAs) have attracted widespread attention due to the excellent toughness and corrosion resistance, but its relatively low hardness results in poor tribological properties. Herein, a series of FeCrNiSix MEAs (x = 0, 0.1, 0.15,

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

open access: yesAdvanced 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 ...
