ApNano Materials, Inc.,
a cleantech company and provider of nanotechnology-based products, today announced
that new test conducted at the FZG Gear Research Centre of the Technical University
of Munich, Germany, clearly shows that ApNano Material's nanotechnology-based
lubricant NanoLub significantly decreases damaging wear pits on gear teeth.
The test was done on oil that was formulated with a NanoLub additive.
"The test proves that NanoLub significantly enhances automotive and industrial
gear oils, improving pitting resistance," said Dr. Menachem Genut, ApNano
Materials' President and CEO. "Gear teeth are especially vulnerable to
micro-pitting and reducing this damage can save high costs of replacement and
repair, making the gears operational 24/7. For Example, Anglo-American, one
of the largest mining companies in the world has begun to use NanoLub in its
heavy mining equipment in Chile."
"The new test further enhances NanoLub's position in the automotive and
industrial markets, opening new horizons for our innovative lubricant as a necessary
additive to gear oils," said Aharon Feuerstein, ApNano Materials' Chairman
and CFO. "NanoLub is distributed worldwide in Europe, Asia and the Americas
by local agents and distributors. Due to the large demand we have increased
the capacity of our production plant."
Oil blended with NanoLub was evaluated at the FZG Gear Research Centre according
to a recognized international test procedure for investigating the influence
of lubricating oil (especially the quality of additives in these oils) on the
wear and damage of gears.
In such conditions, indications of damage appear as micro-pits or small holes
on the surface of the gears. The test can differentiate between oils of varying
quality and thus facilitates identifying a high quality lubricant additive that
provides adequate resistance to pitting and wear.
The test at the FZG Gear Research Centre follows other tests done by Dr. Adrian
Oila of Newcastle University, England, on gears with heavy duty gear oil that
was blended with NanoLub powder. No wear damage to the steel lubricated with
the NanoLub oil could be observed with an optical microscope, while significant
wear was observed for the reference oil. The presence of a beneficial tribofilm
was detected on the gears lubricated with the NanoLub formulation. The tribofilm
continues to lubricate the moving parts also in cases where the oil supply is
NanoLub, ApNano's proprietary nanotechnology-based lubricant, is based on nanosized
particles of tungsten disulfide (WS2) that have a structure of nested spheres,
called inorganic fullerenes, whose lubrication mechanism includes the layers
slipping off under loads to form an adherent film that reduces friction and
wear . These new nano spheres have first been synthesized by Dr. Menachem Genut
during his post doctorate research. When these particles are used as an additive
to liquid oil or grease, NanoLub significantly enhances the lubricating properties
of the oil or grease with respect to wear and friction by an order of magnitude
versus the same lubricant without this additive. In addition, NanoLub "wraps"
the moving parts with a lubricating thin film called tribofilm and continues
to lubricate normally for a long time, as an "uninterruptable lubrication
source" during severe oil leakages. In addition to the significant reduction
in wear, NanoLub also contributes to a considerable reduction in the friction
between moving parts resulting in a smoother ignition in case of "cold
start", increased power, and to an improved fuel economy with lower emission
of greenhouse effect gases.
