Abstract: The present invention relates to a method of forming a zeolite membrane. The method includes forming an aqueous-based or an alcohol-based sol which can form a zeolite. The sol composition is then disposed on a porous support. The porous support and the sol composition are exposed to an atmosphere and to a temperature sufficent to cause the sol composition to hydrothermally crystallize, thereby forming the zeolite membrane.

Abstract: A method for producing horseshoe crab amebocytes in vitro by isolating amebocyte producing tissue from the gill flaps of horseshoe crabs, especially Limulus polyphemus. In contrast to all previous attempts to isolate and culture amebocytes from Limulus for the production of pyrogen-sensitive lysate, an effective method and means have been developed utilizing the discovery that the gill flaps are the source of the cells which differentiate into competent amebocytes. Once isolated, the tissue can be cultured long term in vitro on an artificial surface or as part of the gill flap leaflets, opened along one edge to allow access of the media to the developing amebocytes. Amebocytes are removed from the gill flaps by pulsing with Limulus serum, copper sulfate, detergent, or combinations thereof.

Abstract: A wound care treatment platform and application employs a mobile device and application (“app”) for on-site capture and gathering of wound images from a patient. The mobile device is in wireless communication with a database including health records and data and trained models of wound image classification. Based on a patient image of a wound under care, the image is analyzed for features indicative of wound health and healing progress. The mobile device invokes a plurality of models for providing an accurate and consistent assessment and treatment recommendation, including evaluating the sufficiency of the patient image gathered by the mobile device, normalizing the patient image for adverse or irregular lighting, common in patient dwellings, adjusting for a distance and angle at which the caretaker obtained the image, computing a comprehensive score of wound healing, and rendering an evaluation for referral or continuance of current outpatient care.

Abstract: Production of high purity iron powder employs high efficiency low temperature electrolysis resulting in a process requiring substantially less energy with no CO2 gas and has high energy reduction. Configurations provide a renewable electricity supply that is environmental benign with low energy consumption. A hematite (Fe2O3), carbon and highly concentrated NaOH combine to form an electronically and ionically conductive suspension for iron production. The suspension is flowable which can also be applied to a flow electrolysis system. High purity iron powder is produced at the cathode side while the anode side can produce O2 gas as a byproduct.

Abstract: A Metaverse Laboratory (ML) is a self-contained comprehensive research and development (R&D) laboratory facility for hybrid modeling and simulation, conceptual and engineering design, prototyping, and experimentation in an operational environment (real, virtual, or augmented) by analyzing consequences based on simulated or actual (live) inputs from either human actors and/or predetermined scenarios. A physical facility encloses a rendering area configured to receive projected images and physical devices or objects. User interaction may be accompanied by image rendering goggles in conjunction with physical interactions with vehicles, objects and/or other users disposed in the rendering area. Computing equipment for driving a rendered scenario directs the outputs including visual and tactile feedback according to the scenario, and input from sensors and users in the rendering area determines a computed response. The collective facility provides a generalized environment for programmed realities for modeling and simulation combined with tangible objects, devices and human actors.

Abstract: A recycling process for exhausted, end-of-life solar panels achieves substantial recovery of silicon and silver, as well as other materials, from a recycling stream of discarded solar panels. Agitation and shredding of the solar panels yield a granular mass, which can be separated by particle size to yield the silicon rich solar cell material. Leaching with a strong base such as sodium hydroxide draws the silicon into the leach solution. Filtration of the leach solution draws off the silicon-rich solution and allows filtration of other valuable materials such as silver. Addition of an acid such as hydrochloric acid to the leach solution then precipitates the silicon into a nano silica powder of in the form of high purity silicon dioxide. The high purity silicon dioxide provides raw materials for recycled solar panels, lithium-ion batteries and other uses depending on the purity.

Abstract: An atomizing spray dryer employs one or more stages defined by ultrasonic transducers in close proximity to a liquid feed opening forming a path of an atomization flow for producing uniform droplets from a close tolerance with the transducer. The atomization flow exits a gap between the transducer and an outer edge of the opening, such that the passed liquid is responsive to an oscillation of the transducer for forming the droplets. A conical or other suitably shaped transducer engages a substantially round liquid feed opening. Subsequent stages may include a circular, ring, or other suitable shape aligned to receive the atomization flow from a circumference of the conical base, or may also take any suitable shape, preferably to receive droplets directed by the first stage.

Abstract: Embodiments of the present innovation relate to a Fourier dot product analog matrix multiplier device. In one arrangement, the analog matrix multiplier device is configured as a set of analog transistor circuits and can include a set of signal generators and a Fourier dot product circuit. The components of the analog matrix multiplier device are configured to perform a Fourier dot product multiplication process relative to coefficients received by the analog matrix multiplier device. The Fourier dot product analog matrix multiplier device leverages the low power capabilities of analog circuits and a mathematical algorithm to reduce the number of components and power required to perform matrix multiplication.

Abstract: A recycling and waste management process receives municipal solid waste (MSW) with substantial organic content to form a self-sustaining Hydrothermal Mineralization (HTM) process based on Supercritical Water Oxidation (SCWO) to receive supercritical steam and carbon dioxide with potential for electrical generation before forming calcium carbonate suitable for concrete production. Hydrothermal mineralization (HTM) provides a rapid elimination of organic wastes while simultaneously producing a non-emissive and thermally stable cement additive to act as a carbon sink. Hydrothermal mineralization (HTM) provides a rapid disposal pathway for organic wastes, a green source of electricity and a final product that can be coupled with traditional and alternative cement productions to reduce carbon footprints of cement production.
