Smart electromagnetically responsive nanoadditized lubricants
Smart electromagnetically responsive nanoadditized lubricants
Global challenges in energy, transport, materials, and manufacturing demand smart lubrication solutions that meet strict environmental regulations, safety standards, and fuel-efficiency targets. The shift to electric and hybrid vehicles introduces new requirements. Hybrid engines operate at lower average temperatures due to frequent start–stop cycles, where low-viscosity oils ease start-up but increase wear. In battery electric vehicles, stray currents and electromagnetic fields affect lubrication, and many motor failures arise from “permanently lubricated” bearings, placing new demands on greases, gear oils, and coolants.
A promising solution is a smart, green additive to replace polluting ZDDP. Tungsten disulphide (2H-WS₂) nanoparticles provide excellent friction reduction through their layered structure and form durable tribofilms under severe conditions. Iron-doped, magnetically responsive WS₂ nanoparticles can be concentrated at contacts using electromagnetic fields, enhancing tribofilm formation, reducing additive dosage, improving stability, and enabling recyclability.

Abstract
Global challenges in energy, transport, materials, and manufacturing demand smart lubrication solutions that meet strict environmental regulations, safety standards, and fuel-efficiency targets. The shift to electric and hybrid vehicles introduces new requirements. Hybrid engines operate at lower average temperatures due to frequent start–stop cycles, where low-viscosity oils ease start-up but increase wear. In battery electric vehicles, stray currents and electromagnetic fields affect lubrication, and many motor failures arise from “permanently lubricated” bearings, placing new demands on greases, gear oils, and coolants.
A promising solution is a smart, green additive to replace polluting ZDDP. Tungsten disulphide (2H-WS₂) nanoparticles provide excellent friction reduction through their layered structure and form durable tribofilms under severe conditions. Iron-doped, magnetically responsive WS₂ nanoparticles can be concentrated at contacts using electromagnetic fields, enhancing tribofilm formation, reducing additive dosage, improving stability, and enabling recyclability.
