Embodiments of the present invention may include a macro-composition with a special structure. The structure includes a layered macro-composition made of a nanoparticle as an inner nucleus, an intermediate layer around the nucleus, and an outer layer intercalated with the nucleus or encapsulating the nucleus and the intermediate layer. A plurality of the layered macro-compositions is bonded together by bonds, so that each layered macro-composition is bonded to at least one other such layered macro-composition. Embodiments include a macro-composition made of three 3-layered macro-compositions joined in a chain by two bonds. These macro-composition assemblies may take the shape of layered macro-compositions bonded together in chains, or forming other shapes, such as rings. The layered macro-composition may be no more than about 100 nanometers in size, for example. The bonds of the complex macro-composition may have an average length of no more than about 100 nanometers, for example. Embodiments may be added to lubricants such as oil or grease, to increase their performance.

The objective of this Phase I project is to demonstrate feasibility to design and develop novel nanomanufactured multicomponent lubricant additives applicable for engine, especially engineered as additive for enhancing engine economy with at least 3%. This economy will be enhanced through the power of nanosized multicomponent (multi-chemistry/macromolecular) lubricating agents launching into the intricate spaces between mating surfaces where they form a durable lubricating film that sustains high loads and reduces friction and wear (boundary lubrication regime). Completing this objective will involve systematic scientific investigation of the various complex chemical components that positively impact wear and friction behavior in engine environments and utilization of this knowledge to develop functional nanoparticle based additive compositions for lubricant systems. Based on attractive preliminary analysis at the University of Arkansas for investigating the effects of adding multi-chemistry nanolubricant into regular engine oil, 5.8% increase in power and a proportional increase of efficiency with the additive for single cylinder four stroke 6.5 HP gasoline engine, the project research team led by NanoMech will conduct Phase I feasibility scale laboratory-based tribological evaluation of nanolubricants. The analysis will be performed in order to study friction and wear characteristics using a table-top engine test-vehicle. Preliminary test data indicated a 20 30% reduction in the coefficient of friction (using fundamental ball- on-disk test configuration) when compared with a mineral base oil of similar viscosity as the baseline engine oil. In a separate study, wear test data indicated a 50% improvement in wear scar using industry specified test conditions (4 ball test, ASTM D 4172). Overall, in the Phase I, II, and III iteratively designed and optimized nanolubricant additive formulations will be evaluated using engine tests and field studies to demonstrate meeting engine performance efficiency (per DOE guideline), power gain, fuel economy, and environmental impact reduction. In Phase I, we intend to conduct key tests in cooperation with the Oak Ridge National Laboratory (ORNL-DOE) and University of Arkansas. POTENTIAL partners and end users include Cummins, Wal-Mart, J.B. Hunt, and FedEx, and we plan to cement those relations in the Phase I of this project. The nanomanufacturing process for synthesizing these multi- component lubricants for engine application is scalable for commercial production and is a part of another major successful DOE funded Phase II effort, which is about to be completed.

Embodiments of the present invention may provide textured surfaces to be lubricated, the texturing to enhance the effectiveness of the intended nano-lubrication. The texturing may make asperities and depressions in the surface to be lubricated. This texturing may be executed, for example, by chemical etching, laser etching, or other techniques. This texturing may create locations in the lubricated surface to hold or anchor the intended nano-lubricants, to facilitate the creation of a tribo-film on the surface when the lubricated surface is used under pressure, and resulting in delivery of multiple chemistries from the nano-lubricant.


Compositions having a plurality of hard particles and a plurality of lubricant nanoparticles are disclosed. Methods of making and using the compositions are also disclosed.


Additive packages including multifunctional additive molecules are disclosed, including, for example, organic medium intercalated with lubricant nanoparticles. The additive package may be greaseless or may he added to materials such as base oils or greases, greaseless materials, or anti-corrosives, for example. The additive package added to materials may form a coating or lubricant that may be added to a surface of an object.


A method of depositing particles onto a substrate utilizes a liquid dispersant into which the particles are introduced prior to spraying upon the surface. The ratio of the particles to the dispersant, as well as the volume of the dispersant, may be used to control the density of the particles that result on the substrate after spraying.

A composition that includes solid lubricant nanoparticles and an organic medium is disclosed. Also disclosed are nanoparticles that include layered materials. A method of producing a nanoparticle by milling layered materials is provided. Also disclosed is a method of making a lubricant, the method including milling layered materials to form nanoparticles and incorporating the nanoparticles into a base to form a lubricant.


The present invention provides a simple and economical process for preparation of metal-coated non-metallic nano/micro particles. The nano/micro particles are composed of a core and metallic coat over the core using silver or other transition/noble metals. The core of the non-metallic nano/micro particles are selected from inorganic material such as silica, calcium carbonate, barium sulfate, or emulsion grade polyvinyl chloride and other polymers prepared by emulsion process including porous polymers. The metal coating is selected from the transition/noble metals such as copper, nickel, silver, palladium, platinum, osmium, ruthenium, rhodium, and such other metals and their combinations that are easily reducible to elemental metal.
