  • Patent number: 11334854
    Abstract: Methods, apparatus, systems, and articles of manufacture to generate an asset workscope are disclosed. An example system includes an asset health calculator to identify an asset on which to perform maintenance based on generating a first asset health quantifier corresponding to a first asset health status, a task generator to determine a first workscope including first asset maintenance tasks, and a task optimizer to determine a second workscope including second asset maintenance tasks based on the first asset health quantifier and/or first workscope. The example system includes a workscope effect calculator to generate a second asset health quantifier corresponding to a second asset health status when the second workscope is completed on the asset, and to update the asset health calculator, task generator, and/or task optimizer to improve determination of first and/or second workscopes to improve the second asset health quantifier relative to the first asset health quantifier.

  • Patent number: 11123433
    Abstract: A variety of hydrophobically modified polypeptoids are provided. The hydrophobically modified polypeptoids can include a polyamide backbone having a random copolymer of two or more different types of repeat units, where one or more of the repeat units have nitrogen atom having a hydrophobic substituent attached thereto. Methods of making the hydrophobically modified polypeptoids are also provided, as well as uses of the hydrophobically modified polypeptoids, for example in liposomal drug delivery.

  • Patent number: 11045427
    Abstract: The present invention discloses the morphology of hollow, double-shelled submicrometer particles generated through a rapid aerosol-based process. The inner shell is an essentially hydrophobic carbon layer of nanoscale dimension (5-20 nm), and the outer shell is a hydrophilic silica layer of approximately 5-40 nm, with the shell thickness being a function of the particle size. The particles are synthesized by exploiting concepts of salt bridging to lock in a surfactant (CTAB) and carbon precursors together with iron species in the interior of a droplet. This deliberate negation of surfactant templating allows a silica shell to form extremely rapidly, sealing in the organic species in the particle interior. Subsequent pyrolysis results in a buildup of internal pressure, forcing carbonaceous species against the silica wall to form an inner shell of carbon. The incorporation of magnetic iron oxide into the shells opens up applications in external stimuli-responsive nanomaterials.

  • Patent number: 10949813
    Abstract: Methods, apparatus, systems, and articles of manufacture to generate workscope tasks. An example apparatus includes a workscope task generator and a workscope task processor. The example workscope task generator is to process an asset health quantifier and a next mission criterion for a target asset according to a workscope transfer function to generate a set of workscope tasks for maintenance of the asset at a desired health state to satisfy the next mission criterion, the workscope tasks involving a location, a resource, and a time for maintenance of the engine. When the generated set of workscope tasks does not satisfy a lifecycle expectation for the asset, the generated set of workscope tasks is modified by the workscope task processor to generate a set of targeted, forecast workscope tasks from the modified set of workscope tasks to trigger maintenance of the engine.

  • Publication number: 20200193392
    Abstract: An initial customized electronic work scope is created for an individual industrial asset. The initial electronic work scope is created according to the set of rules defined in the tree-like data structure and uses the determined condition of the asset. The initial customized electronic work scope is not necessarily the same as other work scopes of other industrial assets the same asset type. The initial customized electronic work scope defines an ordered sequence for removing a plurality of individual mechanical parts of the individual asset.

  • Patent number: 10653786
    Abstract: Provided herein relates to compositions and methods for lubrication of a surface. The surface amenable to the compositions and methods described herein can be a non-biological surface, a biological surface, or a combination thereof.

  • Publication number: 20160114303
    Abstract: The creation of novel halloysite-based compositions is disclosed. In one embodiment, the hollow clay nanotubes of halloysite are loaded with nanoscale zerovalent iron particles. The resulting composition provides an effective manner of remediating chlorinated hydrocarbons. In another embodiment, the hollow clay nanotubes of halloysite are imbibed with dispersants such as DOSS and Tween 80 surfactants. The resulting composition stabilizes oil-in-water emulsions and subsequently releases the surfactants, thereby reducing interfacial tension significantly, which allows much smaller droplets to form and thus provides for more effective oil remediation.

  • Publication number: 20130058724
    Abstract: Effective in-situ injection technology for the remediation of dense nonaqueous phase liquids (DNAPLs) such as trichloroethylene (TCE) benefits from the use of decontamination agents that effectively migrate through the soil media, and react efficiently with both dissolved TCE and bulk TCE. A novel decontamination system contains highly uniform carbon microspheres preferably in the optimal size range for transport through the soil. The microspheres are preferably enveloped in a polyelectrolyte (such as carboxymethyl cellulose, CMC) to which preferably a bimetallic nanoparticle system of zerovalent iron and Pd is attached. The carbon serves as a strong adsorbent to TCE, while the bimetallic nanoparticles system provides the reactivity. The polyelectrolyte serves to stabilize the carbon microspheres in aqueous solution. The overall system resembles a colloidal micelle with a hydrophilic shell (the polyelectrolyte coating) and a hard hydrophobic core (carbon).
