Abstract: A system for modifying pH in an aqueous environment comprises an aqueous salt solution feed stream having a first pH and an electrochemical device positioned proximate an aqueous restoration area. The electrochemical device is configured to receive the feed stream and convert the feed stream to an acid stream and a base stream having respective predetermined pH values. A first effluent stream comprises the base stream, wherein the first effluent stream has a second pH that is higher than the first pH. The first effluent stream is delivered proximate the aqueous restoration area. A second effluent stream comprises the acid stream, wherein the second effluent stream has a third pH that is lower than the second pH.

Abstract: A particle is provided that includes a first material and a second material, arranged to provide a Fano resonance effect, for example in the visible portion of electromagnetic spectrum. The first and second materials may be substantially clear in the visible portion of the electromagnetic spectrum. The first material may include an inorganic material, such as SiO2, TiO2, HfO2, ZrO2, diamond, or a combination thereof. The second material may include a polymer. The first material has a first refractive index and the second material has a second refractive index, where the first refractive index and second refractive index have a difference of 0.5 or greater, and 1.0 or less. The first material may form a core and the second material may form a shell surrounding the core. Alternatively, the first and second materials may form a Janus particle, an asymmetric dimer, or an aggregate.

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 polymer compound containing groups having the chemical structure:
where NH2 is a primary amine, and R is not hydrogen, and a polymer backbone wherein two of the R groups are part of the polymer backbone. A method of synthesizing a polymer includes polymerizing amine-convertible monomers to produce a polymer, causing a deprotection reaction with the polymer to form an isocyanate, decomposing the isocyanate to form a polymer containing primary amines. A method to separate CO2 from other gases comprising using a sorbent containing a polymer compound having the structure:
where NH2 is a primary amine, and R is not hydrogen, and a polymer backbone wherein two of the R groups are part of the polymer backbone.-

Abstract: A gas separation system has system input inlet configured to receive a stream mixture including a target gas, one or more spray generators positioned to spray a non-sprayable liquid to change a concentration of the target gas in the non-sprayable liquid, one or more system outlets positioned to outlet an output material, wherein at least one of the system outlets outputs a material having a lower amount of the target gas than the input stream mixture, and a recirculating path connected to the one or more outputs and the input inlet to allow recirculation of the non-sprayable liquid. A method of performing gas separation includes absorbing a target gas from an input stream in a non-sprayable capture liquid, and releasing the target gas in an output gas stream by spraying the non-sprayable capture liquid into a heated volume using a spray generator. A method of performing gas separation includes receiving an input stream that includes a target gas, using one or more spray generators to apply a non-sprayable liquid as a spray to the input stream to change a concentration of the target gas in the liquid, and outputting the liquid with the changed concentration through an outlet.

Abstract: A membraneless electrochemical device comprises a fluid feed stream input to the membraneless electrochemical cell, a first electrode, and a second electrode. The first electrode comprises a first redox-active material configured to have a proton-coupled oxidation reaction with a first portion of the fluid feed stream, and the second electrode comprises a second redox-active material configured to have a proton-coupled reduction reaction with a second portion of the fluid feed stream. The first portion and the second portion of the fluid feed stream are separated. A first effluent stream comprises the first portion and has a first pH, and a second effluent stream comprises the second portion and has a second pH, different from the first pH.

Abstract: A composition of matter has a molecularly imprinted polymer having templated pores, and a reactive material occupying a portion of each pore, the reactive material selected to react when an analyte material for which the cavities are templated enters the cavities. A method of synthesizing a molecularly imprinted polymer includes arranging monomers around a template molecule having a reactive component and an analyte component, polymerizing the monomers, removing the template molecule, and reintroducing the reactive component of the template molecule. A method of detecting an analyte includes exposing a molecularly imprinted polymer to a fluid, the polymer having templated pores containing a detector material that is reactive to an analyte.
