A method of upcycling polymers to useful hydrocarbon materials. A catalyst with nanoparticles on a substrate selectively docks and cleaves longer hydrocarbon chains over shorter hydrocarbon chains. The nanoparticles exhibit an edge to facet ratio to provide for more interactions with the facets.

Catalytic upcycling of polyolefins into lubricants

A non-stoichiometric nanocomposite coating and method of making and using the coating. The non-stoichiometric nanocomposite coating is disposed on a base material, such as a metal or ceramic; and the nanocomposite consists essentially of a matrix of an alloy selected from the group of Cu, Ni, Pd, Pt and Re which are catalytically active for cracking of carbon bonds in oils and greases and a grain structure selected from the group of borides, carbides and nitrides.

Sub-stoichiometric metal nitrides

Systems and processes for forming seals. The seals have graphene embedded in the seal. The graphene-embedded seals exhibit improved wear resistance over seals without graphene.

Graphene embedded seal

A low friction wear surface with a coefficient of friction in the superlubric regime including graphene and nanoparticles on the wear surface is provided, and methods of producing the low friction wear surface are also provided. A long lifetime wear-resistant surface including graphene exposed to hydrogen is provided, including methods of increasing the lifetime of graphene containing wear surfaces by providing hydrogen to the wear surface.

Low friction wear resistant graphene films

A system and method for forming at least one of graphene and graphene oxide on a substrate and an opposed wear member. The system includes graphene and graphene oxide formed by an exfoliation process or solution processing method to dispose graphene and/or graphene oxide onto a substrate. The system further includes an opposing wear member disposed on another substrate and a gas atmosphere of an inert gas like N, ambient, a humid atmosphere and a water solution.

Superlubricating graphene and graphene oxide films

Provided herein are lubricant compositions and methods of using the same. These lubricant compositions are useful for providing improved anti-friction and anti-wear properties.

Catalytically active lubricants

A hydrogenated diamond-like coating ('H-DLC') for metallic substrates provides improved reliability. The H-DLC is relatively soft and elastic. Unlike hard and/or inelastic coatings in the prior art, the present coatings do not exhibit a loss of adhesion (delamination). A bonding layer may be used between the metallic substrate and the H-DLC. H-DLC coatings can, for example, be used in bearings and gears to reduce the occurrence of micropits and, ultimately, product failure.

Pitting resistant carbon coatings

A nanocomposite coating that in turn extract self-replenishing (or -healing), superlubricious carbon film directly from natural gas or hydrocarbon gas in mechanical systems. The coating deposits on sealing and sliding surfaces reducing friction and wear. The result is a reduction in inefficiency, machine breakdown, and adverse environmental impact.

Superlubricious carbon films derived from natural gas

Lubricant compositions, core-shell nanoparticles, and related methods are disclosed. In an exemplary embodiment, a lubricant composition includes a plurality of core-shell nanoparticles. The nanoparticles include a core, a first shell disposed on the core, and a second shell disposed on the first shell. The first shell is formed from a siliceous material and the second shell is formed from a hydrophobic material. The first and second shells form functional coatings that reduce wear and friction of parts lubricated with the lubricant composition.

Lubricant compositions comprising core-shell nanoparticles

A low friction wear surface with a coefficient of friction in the superlubric regime including graphene and nanoparticles on the wear surface is provided, and methods of producing the low friction wear surface are also provided. A long lifetime wear resistant surface including graphene exposed to hydrogen is provided, including methods of increasing the lifetime of graphene containing wear surfaces by providing hydrogen to the wear surface.

A hard, wear resistant coating and a method of forming the coating on a substrate to be exposed to hydrocarbons is provided. A substrate is provided in a chamber. A film is deposited onto the substrate by physical vapor deposition (PVD), where the film includes a bulk layer and an outer termination layer. The deposition of the termination layer is mitigated. The termination layer is removed from the film, leaving the remaining bulk layer disposed over the substrate. And when the substrate is exposed to hydrocarbons in an environment having wear additives, friction modifiers, or naturally occurring compounds, a durable tribological layer is formed on an outer surface of the bulk layer to create a coating having low friction and anti-wear properties.

Hard and low friction nitride coatings

A nanocomposite coating and method of making and using the coating. The nanocomposite coating is disposed on a base material, such as a metal or ceramic; and the nanocomposite consists essentially of a matrix of an alloy selected from the group of Cu, Ni, Pd, Pt and Re which are catalytically active for cracking of carbon bonds in oils and greases and a grain structure selected from the group of borides, carbides and nitrides.

Method to produce catalytically active nanocomposite coatings

A lubricant composition includes an oil including a plurality of long-chain hydrocarbon molecules. A quantity of a catalytically active metal-organic additive is mixed with the oil. The metal-organic additive is formulated to fragment the long-chain hydrocarbon molecules of the oil into at least one of dimers and trimers under the influence of at least one of a mechanical loading and a thermal loading. In some embodiments, the metal-organic additive includes a compound of formula II: where:
