Abstract: A test strip includes a substantially transparent substrate and one or more colorimetric test spots on the transparent substrate. Each colorimetric test spot has one or more sensing chemicals chemically attached onto a porous support material. The porous support material has at least one exposed surface configured to absorb a body fluid. The one or more sensing chemicals are configured to change a color in response to a presence of a target drug in the body fluid.

Abstract: A composition of matter includes a first compatible material having particles containing chemical elements similar to a first substrate, and second compatible material having particles containing chemical elements similar to a second substrate, wherein the first substrate and the second substrate are chemically different. The particles are dispersed into a matrix that is in between the first and the second substrate. A deposition system has a multi-material printhead, a first reservoir of a first compatible material having particles containing chemical elements similar to a first substrate, a second reservoir of a second compatible material having particles containing chemical elements similar to a second substrate, a third reservoir of an polymer precursor material, and at least one mixer. A method of bonding a joint between dissimilar substrate materials includes functionalizing a first compatible material having chemical elements similar to a first substrate, mixing the first compatible material with a polymer precursor material, functionalizing a second compatible material having chemical elements similar to a second substrate, mixing the second compatible material with a polymer precursor material, and using the deposition system to deposit the first and second compatible materials and a polymer precursor material on the joint between the first and second substrate materials.

Abstract: A flowing electrolyte fuel cell system design (DHCFC-Flow) is provided. The use of a flowing oxygen-saturated electrolyte in a fuel cell offers a significant enhancement in the cell performance characteristics. The mass transfer and reaction kinetics of the superoxide/peroxide/oxide ion (mobile oxygen ion species) in the fuel cell are enhanced by recirculating an oxidizing gas-saturated electrolyte. Recirculating oxygen-saturated electrolyte through a liquid channel enhances the maximal current observed in a fuel cell. The use of a oxygen saturated electrolyte ensures that the reaction kinetics of the oxygen reduction reaction are fast and the use of convection ameliorates concentration gradients and the diffusion-limited maximum current density. The superoxide ion is generated in situ by the reduction of the oxygen dissolved in the gaseous electrolyte. Also, a dual porosity membrane allows the uniform flow of fuel (e.g., methane) on the fuel side, without allowing phase mixing. The capillary pressure for liquid intrusion into the gas phase and vice versa is quite large, estimated to be 1-10 psi. This makes it easier to control the fluctuations in gas/liquid velocity which might otherwise lead to phase mixing and the loss of fuel cell performance. In one variation, a dual-porosity membrane structure is incorporated in the system to allow uniform flow of fuel and prevent mixing of fuel with a liquid electrolyte.

Abstract: A bilayer object consisting of a carbon fiber reinforced polymer substrate coated with a composition of matter comprising horizontally aligned exfoliated graphene sheets dispersed in an epoxy binder. A method includes depositing graphene into a hardener, mixing the hardener and the graphene to produce a homogenous composite mixture, adding a resin material to the composite mixture to produce an epoxy graphene material, coating a structure with the epoxy graphene material, aligning the graphene sheets in the in-plane orientation, and curing the epoxy graphene material.

Abstract: Today, energy requiring equipment commonly relies on batteries for power. The excessive weight and size of batteries severely limits their performance. Described herein is a lightweight portable energy system which includes an ultra-high capacity hydrolysable hydride gel cartridge for use in supplying hydrogen gas to hydrogen based energy generators. Hydrolysable hydride reactivity is controlled by tuning the amounts of hydrophilic and hydrophobic content in a polymer gel encapsulant of the cartridge.
