  • Patent number: 10261022
    Abstract: Processes for sensing a variety of toxic chemicals and/or processes for determining the residual life of a filter or filtration system are provided. Exemplary process for sensing a toxic chemical include contacting a toxic chemical, or byproduct thereof, with a sorbent that includes a porous metal hydroxide and a transition metal reactant suitable to react with a toxic chemical or byproduct thereof. The sorbent is contacted with the toxic chemical or byproduct thereof for a sampling time. A difference between a post-exposure colorimetric state of the sorbent and a pre-exposure colorimetric state of the sorbent or control is determined to thereby sense exposure to, or the presence of, the toxic chemical or byproduct thereof.

  • Patent number: 10256445
    Abstract: A battery separator for a lithium-ion battery includes a nonwoven fiber mat that is composed of entangled microfibers having an average fiber diameter of less than 6 microns. The nonwoven fiber mat also includes a binder that binds the microfibers together and a polymer component that is dispersed homogeneously through or within the entangled microfibers so that the polymer component is uniformly distributed throughout the nonwoven fiber mat and so that the entangled microfibers, the binder, and the polymer component form a single layer component or product. The polymer component is configured to melt within the nonwoven fiber mat when exposed to a sufficiently high heat in order to effectively interrupt an electro-chemical process of the lithium-ion battery and thereby prevent overheating of the lithium-ion battery. The nonwoven fiber mat is typically between 0.1 and 20 mils thick.

  • Patent number: 10207938
    Abstract: An apparatus and method for capturing a contaminant present in a body of water that includes a collection media for capturing the contaminant and a structure. The collection media has a first end secured to the structure. The collection media has a second buoyant end disposed opposite the first end wherein buoyant end is a free end. The structure does not float at the water surface and holds the first end of the collection media below the buoyant second end in the water column. When the apparatus is deployed in a water column having a depth greater than the height of the apparatus, the apparatus is selectively positioned in the water column at a desired height. A method of employing the collection media is also disclosed.

  • Patent number: 10189934
    Abstract: A polymerization process, preferably a living radical polymerisation process, is carried out in the presence of a template substance, to produce molecularly imprinted polymers (“MIPs”). It is controlled so that the products are quite small (500-106 Daltons) so that they are soluble or form colloidal suspensions. The template substances are immobilized templates, which can be re-used. Immobilized templates are also useful for purification of MIP solutions/suspensions by affinity chromatography.

  • Patent number: 9989471
    Abstract: There is a need in the point-of-care diagnostic community for an efficient and portable method for testing blood and other biological fluids that can be easily translated across multiple applications. An aspect of the invention described involves monitoring the optical properties of molecularly-mediated nanoparticle assemblies though an optically transparent and magnetically active microfluidic chip, which has recently emerged as an attractive method for biomarker detection as it is an efficient tool for monitoring the binding events that take place in a sensing assay. In one embodiment, this device is directed towards two-nanoparticle assays that rely on the assembly or disassembly of plasmonic and magnetic nanoparticles in response to a certain analyte. A further embodiment is directed to a spiral microfluidic using inertial forces to filter fluid components by size, connected to a magnetically active channel comprised of a nickel micropad array, optically transparent microchannel, and permanent magnets.
