Lubricant incorporates nanospheres

An Apnano Materials product story
Edited by the Engineeringtalk editorial team May 13, 2008

NanoLub is made up of particles of tungsten disulfide (WS2) that have a structure of nested spheres, called inorganic fullerenes.

The Multisol Group and InS are distributing lubricant additives in Europe that are based on ApNano Materials' NanoLub, the world's first commercial nanotechnology-based solid lubricant.

The lubricants significantly reduce the friction and wear of moving parts and give excellent performance under extreme tribological conditions.

NanoLub saves money, reduces pollution, is cost-effective, safe and environmentally-friendly.

Tests done under OECD international protocols prove that NanoLub is nontoxic or harmful.

The enhanced lubricants are suitable for the automotive, industrial, aerospace and biomedical markets.

NanoLub is made up of particles of tungsten disulfide (WS2) that have a structure of nested spheres, called inorganic fullerenes.

The particles lubricate by rolling like billions of miniature ball bearings.

The moving parts are also covered with a thin lubricating film called tribofilm, which covers the asperities or protrusions on surfaces, some only viewable under electron microscopes, that are the major cause of friction between sliding parts moving against one another.

NanoLub is used as an additive to liquid oil or grease and significantly enhances the lubricating properties of the oil or grease with respect to wear and friction by an order of magnitude.

ApNano Materials produces NanoLub at its automated plant in Israel.

Multisol has committed significant resources and capital to the market development of NanoLub over the next three years.

ApNano Materials, Multisol and InS will also continue their efforts in the field of special coatings based on NanoLub.

"The partnership between the three companies will enable European users to benefit from lubricants and greases that include a sophisticated and innovative nanotechnology-based additive with super-lubricity capabilities", said Dr Menachem Genut, President and CEO of ApNano Materials.

Dr Genut was a research fellow in the original research group which discovered the inorganic fullerene nanoparticles at the Weizmann Institute of Science, Israel and was the first to synthesise the new material.

The group was led by Professor Reshef Tenne, currently the Director of Helen and Martin Kimmel Centre for Nanoscale Science at the Weizmann Institute.

InS will use its tribological laboratories to identify industrial applications for NanoLub-based lubricants and maximise the benefits from the material's properties.
