Abstract: A system for capturing CO2 gas comprising: a gaseous feed stream having an initial concentration of the CO2 gas; wherein the gaseous feed stream is provided to a first reactor as a gaseous reaction stream; the first reactor comprising a sorbent composition and the gaseous reaction stream flowing therein, the gaseous reaction stream being in contact with the sorbent composition; and a first gaseous output stream having a concentration of CO2 being less than the initial concentration of CO2; wherein: the gaseous reaction stream comprises the CO2 gas and is characterized by a relative humidity of at least 5%; the sorbent composition comprises a metal carbonate material that reacts with the CO2 gas of the gaseous reaction stream thereby reducing CO2 gas concentration; and the first reactor comprises 35 wt. % or less of liquid water by weight of sorbent and liquid water.

Abstract: The systems and methods for wastewater treatment comprise a porous substrate with photocatalytic material(s), and optionally electrocatalytic material(s), for generation of hydroxyl radicals that decompose contaminants in wastewater. The systems and methods intentionally facilitate the photocatalytic and/or electrocatalytic generation of oxygen bubbles, which facilitate an increase in concentration of hydroxyl radicals and shrink the liquid layer of wastewater at photocatalytic and/or electrocatalytic surfaces where hydroxyl radicals are generated in order to decrease quenching of hydroxyl radicals and simultaneously increase utilization or efficiency of the hydroxyl radicals for decomposition of contaminants. In embodiments, the systems and methods prolong hydroxyl radical lifetime and enhance water treatment performance for residential, commercial, municipal, medical, and/or industrial applications.

Abstract: Disclosed herein is a membrane-based, in-gel loop-mediated isothermal amplification (LAMP) system, kit and method for detection of a target microorganism in a sample suspected of containing the microorganism. LAMP reagents, a lysing agent and a hydrogel are placed together on a filter membrane loaded with a pre-filtered sample. The hydrogel polymerizes over a short time to immobilize any target DNA/RNA particles on the membrane. The system may include a compact, portable device that integrates heat incubation and fluorescence illumination, and also a cloud-based smartphone image analysis application for quantitative results interpretation. If target DNA/RNA are present in the sample, fluorescent amplicons are produced as a result of LAMP reaction. The target microorganisms are detected by visually detecting the presence or absence of the amplicons.
