  • Publication number: 20240082820
    Abstract: The present disclosure pertains to core-shell particles that are superficially porous, polymer-based, and include organic-inorganic materials. In various embodiments, a non-porous polymer core is surface modified. In various embodiments, a non-porous hybrid organic-inorganic material is in contact with the modified surface of the core, and a porous hybrid organic-inorganic material is in contact with the non-porous hybrid organic-inorganic material. The present disclosure pertains to chromatographic separation devices that comprise such core-shell particles.

  • Patent number: 10962028
    Abstract: A method of making an additively manufactured ejector pump includes creating a computer file defining the ejector pump in layers. The ejector pump includes a duct extending along a centerline from an upstream end to a downstream end, a nozzle extending inward from the duct including a flowpath, an annulus connected to the duct including a cavity. The method also includes building the ejector pump using an additive manufacturing process that builds the ejector on a layer-by-layer basis from the upstream end to the downstream end.

  • Patent number: 10633099
    Abstract: A water extractor includes a body with an outer wall, an inlet, an outlet, a first centerline axis, an inner nozzle, an outer chamber, a serpentine channel, a pocket, and a boss. The first centerline axis extends through a center of the body, the outlet, and the inlet. The inner nozzle is co-axial with the first centerline axis. The outer chamber extends between the outer wall and the inner nozzle. The serpentine channel fluidly connects the inlet and the outer chamber. The pocket is fluidly connected to a portion of the outer chamber and is configured to collect water from the outer chamber. The boss extends from and is fluidly connected to the pocket. The boss includes a second centerline axis at an angle with the first centerline axis of approximately 10 degrees or greater.
