  • Patent number: 12161972
    Abstract: Provided herein are methods of removing carbon dioxide from an aqueous stream or gaseous stream by: contacting the gaseous stream comprising carbon dioxide, when present, with an aqueous solution comprising ions capable of forming an insoluble carbonate salt; contacting the aqueous solution comprising carbon dioxide with an electroactive mesh that induces its alkalinization thereby forcing the precipitation of a carbonate solid from the solution and thereby the removal of dissolved inorganic carbon by electrolysis; and removing the precipitated carbonate solids from the solution, or the surface of the mesh where they may deposit. Also provided herein are flow-through electrolytic reactors comprising an intake device in fluid connection with a rotating cylinder comprising an electroactive mesh, and a scraping device and/or liquid-spray based device for separating a solid from the mesh surface.

  • Publication number: 20240360567
    Abstract: A method for producing one or more hydroxide solids includes providing a catholyte comprising an electrolyte solution; contacting the catholyte with an electroactive mesh cathode to electrolytically generate hydroxide ions, thereby precipitating the one or more hydroxide solid(s); and removing the one or more hydroxide solids from the surface of the mesh where they may deposit.

  • Publication number: 20240342649
    Abstract: Disclosed herein are methods of capturing CO2 from a gas source using electrochemically-enhanced amine capture to form a concentrated CO2 vapor, followed by sequestering CO2 from the concentrated vapor in a sequestration step. The sequestration step includes contacting the concentrated vapor with an aqueous sequestration solution comprising ions capable of forming an insoluble carbonate salt, such that the aqueous sequestration solution comprises the CO2, electrochemically basifying the sequestration solution, thereby precipitating a carbonate solid, separating the carbonate solids from the aqueous sequestration solution or the surface of the mesh.

  • Patent number: 12042765
    Abstract: Disclosed herein are methods of electrochemically enhanced amine-based CO2 capture and systems for performing the methods of amine-based CO2 capture. The present methods and systems advantageously may be carried out at ambient temperatures and allow for reusing the amine through multiple cycles.

  • Publication number: 20240188705
    Abstract: A versatile ambidextrous pouch worn on the front central abdominal waist of user. provides quick access to handheld accessories for automotive detailing and other interchangeable tool uses, regardless of whether the user is right-handed or left-handed. The tool pouch enables both right-handed workers and left-handed workers to choose a primary, frequently used tool for the dominant hand of the worker and a secondary less used tool for the less dominant hand interchangeably, so that the primary tool can be advanced directly forward from the front central abdominal waist of the user, without awkwardly reaching across the abdomen to grasp a tool and move it angulary across the user's abdomen toward a work surface. Multiple other accessory tools are attached in and out of the pouch.

  • Patent number: 11236379
    Abstract: A Raman spectroscopy based system and method for examination and interrogation provides a method for rapid and cost effective screening of various protein-based compounds such as bacteria, virus, drugs, and tissue abnormalities. A hand-held spectroscope includes a laser and optical train for generating a Raman-shifting sample signal, signal processing and identification algorithms for signal conditioning and target detection with combinations of ultra-high resolution micro-filters and an imaging detector array to provide specific analysis of target spectral peaks within discrete spectral bands associated with a target pathogen.

  • Publication number: 20060249604
    Abstract: A fuel injection valve and director plate assembly including a circular beveled valve seat, a valve ball for forming a circular sealing line against the seat, and a perforated director plate. The improved valve seat is substantially thicker than a prior art seat to provide greater mass of seat material and hence reduced vulnerability of the seat to thermal distortion from welding. To obviate an increase in residual fuel volume that would result from displacing the director plate from the valve by the added thickness of the seat, the central portion of an improved director plate is made concave such that the actual fuel-directing portion of the director plate is to the valve ball in the prior art relationship, thus preserving the desirably small prior art volume of residual fuel after valve closing.
