Abstract: The present invention relates to a method for curing a defect in the fabrication of a composite gas separation module and to composite gas separation modules formed by a process that includes the method. The present invention also relates to a method for selectively separating hydrogen gas from a hydrogen gas-containing gaseous stream. The method for curing a defect in the fabrication of a composite gas separation module includes depositing a first material over a porous substrate, thereby forming a coated substrate, wherein the coated substrate contains at least one defect. Then, the coated substrate can be selectively surface activated proximate to the defect, thereby forming at least one selectively surface activated region of the coated substrate. A second material can be then preferentially deposited on the selectively surface activated region of the coated substrate, whereby the defect is cured.

Abstract: The present invention relates to a method for fabricating a composite gas separation module and to gas separation modules formed by the method. The present invention also relates to a method for selectively separating hydrogen gas from a hydrogen gas-containing gaseous stream. In one embodiment, the method for fabricating a composite gas separation module includes depositing a first material on a porous substrate, thereby forming a coated substrate. The coated substrate is abraded, thereby forming a polished substrate. A second material is then deposited on the polished substrate. The first material, the second material, or both the first material and the second material can include a gas-selective material. For example, the gas-selective material can include a hydrogen-selective metal, e.g., palladium, or an alloy thereof. In one embodiment, the method includes the step of forming a dense gas-selective membrane over the porous substrate. Practice of the present invention can produce gas separation modules that have thinner and/or more uniform dense gas-selective membranes than are possible using conventional manufacturing techniques.

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 sufficient 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 has 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: Lithium recycling from expended Li-Ion batteries occurs thought selective recovery of lithium charge materials from a recycling stream including transition metals used for the charge material. Li recovery includes dissolving the lithium based charge material in an organic acid having a resistance or lack of affinity to dissolution of transition metals, and distilling a leach solution formed from the dissolved charge material for generating a powder including lithium and trace impurities of the transition metals. Sintering of the generated powder forms lithium carbonate and carbonates of the trace impurities that eluded the selective leach, however, since the trace impurities are insoluble in water, the lithium carbonate is recoverable by water washing.

Abstract: A carbon coating such as graphene formed on an article or component forms a reduced friction surface on the component. The graphene forms a superlubricity coating for mitigating friction against engaged, moving surfaces. A metallic component receives a graphene coating resulting from a high temperature biowaste treatment (HTBT) by surrounding the metallic component with a granular biowaste medium defining a carbon source, and heating the metallic component in the biowaste medium for diffusing carbon from the biowaste medium to aggregate on a surface of the component, thereby forming a graphene coating.

Abstract: A photoacoustic (PA) sensor device has a localization feature that defines a position of the sensor or scan information with a coordinate frame defining relative positions a scanned specimen and sensor information of other imaging planes of the scanned specimen. The coordinate frame is defined by positional information from localization markers at a known offset from the sensor, or from position signals from a robotic actuator driving the sensor. A processor coalesces the sensor information and positional information to reconstruct a 3-dimensional rendered structure by stitching together the sensor information to form a continuous rendering. Stitching may include adjacent imaging planes at an angular offset due to a varied pose of the sensor, and/or adjacent images over a lateral area too large for a single scan or imaging plane to capture.

Abstract: A low temperature, liquid metal approach provides a metal-air battery at room temperature or slightly above for high current density, using ambient oxygen as an electrode without the need for high heat for an opposed metal electrode. A metal-air battery employs a low melting point metal such as gallium for an all-fluid battery having a flowing aqueous electrolyte for maintaining a large volume of electrical storage capacity separate form a relatively small reactor or cell for powering an electrical load. Reversibility of the forward discharge (load powering) reaction provides a recharging capability well suited for grid storage to moderate supply and demand variations. The result is an ultra-high density, rechargeable, safe, grid-scale electricity storage technology as an alternative to lithium-ion and solvent-based flow batteries.
