The focus of Nanol’s research has been to overcome the drawbacks of the first generation of lubricant nano-additives. Tungsten disulphide (WS2), molybdenum disulphide (MoS2) and other boron, zirconium and platinum compounds, as well DLC (diamond-like-carbon) nanoparticles all have majör disadvantages. This includes poor dispersion stability, degrade rather quickly, and loss of performance, leading to rapid increase of friction and wear.
chemically unstable, Nanol has used nanotechnology combined with novel production approaches to overcome these problems. Nanol has developed an innovative in-situ redox synthesis process to make copper nanoparticles. This is combined with an enhanced surfactant-assisted dispersion route, to produce unique reverse micelles, in a stable colloid, which ensures that the nanoparticles are chemically stable. These inventive steps have provided the momentum to develop the Nanol breakthrough.
Nanol® contains copper nanoparticles inside reverse micelles within a stable colloid that ensures the additive is completely soluble in oil.
This prevents agglomeration and sedimentation that is a frequent problem with other nanotechnology based additives.
Nanol is a high performance unique additive for lubricant oils and greases. The additive technology is based on the selective transfer concept.
The Nanol micelles transport the copper nanoparticles to the metal surface where, under boundary lubrication conditions, a thin copper tribofilm is formed. This tribofilm has low tangential strength and reduces the coefficient of friction.
Also unlike conventional lubricant additives, the Nanol® copper particles are continuously deposited to selfheal the tribofilm and ensure sustained and robust performance. This Nanol copper tribofilm also has considerable compressive strength to protect against wear. It has been shown that the copper diffuses into the near surface of friction surfaces to further boost wear protection. Nanol® is also different to because the copper tribofilm is only formed on the friction surfaces where it is activated. As a result, the Nanol additive is very selective and does not interfere with the function of other lubricant additives.
Extensive research carried out at Fraunhofer Institute in Germany has demonstrated that Nanol also prevents hydrogen embrittlement by important interactions with reinforced multilayer tribofilms. These reinforced multilayer tribofilms are also critical constituents of the third body that influences running-in kinetics. Thus, Nanol® must be considered a multifunctional package including viscosity index improvement, friction modification, anti-wear properties and protection against hydrogen embrittlement (White Etch Cracking, WEC).
Why We Say "Less Is More"
We believe that our additive formula will become a key technology in the $70-90 billion global lubricants product market. Because the less fuel we consume, the less harmful emissions we produce, and the less we need to repair and replace engines and equipment – the more our businesses and the world we live in have to gain.
Less friction – improving engine performance, reducing fuel consumption by up to 6%, and lessening environmental impact.
Less wear – Nanol’s self-repairing protective nano-layer cuts wear and prolongs the lifetime of components, thus extending maintenance cycles and reducing maintenance costs.
Less consumption – reducing global fuel consumption and emissions through the use of our revolutionary additive in lubrication oils promises very high financial and environmental rewards.
Less emissions – ships consume about 15% of world transport fuels, and new IMO requirements increase the pressure to cut emissions. We have started our rollout by focusing on marine diesel engines.
For lubricants – we believe that our additive formula will become a key technology in the $70-90 billion global lubricants product market.

Summary analysis of test results from lubrication with Nanol
16 field tests and 4 bench tests with 0.3% Nanol in ship engine oils, and 15 laboratory tribotests with 0.3 – 3% Nanol in lubricant oil has been carried out between 2010 and 2017. In ship field tests 4% reduction in fuel consumption was observed for middle size (1600- 0000 kW) diesel engines and 1-2% reduction for large (12600-15600 kW) engines with the use of Nanol additives.
Bench test single observations showed 4% reduction in friction, 0 & 3% reduction in fuel consumption and 1% increase in torque and power in various size (60-4000kW) diesel engines with the use of Nanol additives.

Summary of test results
In a thrust roller bearing test, it was discovered that Nanol reduces friction and prevents the formation of white etching cracks compared to the reference.
The cylinder rollers and the bearing race show an intact surface after the test:
No embrittlement and no corrosion
No indication of lubricant degradation
Summary and conclusions of test results
Nanol lubricant additive was tested at Schaeffler Group in order to assess the influence of Nanol on formation of WEC (White Etching Cracks) in roller bearings.
The test reached a running time of t = 422 h. Failure originated from the surface area of the bearing and was not caused by WECs. Consequently, the oil with Nanol reached at least a tenfold WEC lifetime in comparison with the reference oil (WEC formation at 30-42 h) at mixed friction conditions (at the FE8-25).
