Abstract: In an approach to adaptive library building, a method includes: acquiring one or more spectra for particles from a source material using one or more environmental surveillance sensors; identifying a first set of spectra as an anomalous spectra for an unknown material based on a plurality of spectra for one or more known particles in a particle spectra library; generating a plurality of synthetic spectra for the unknown material using the first set of spectra; creating a synthetic entry with the plurality of synthetic spectra for the unknown material in the particle spectra library; acquiring a second set of spectra for of the unknown material using the synthetic entry and spectra acquired from the one or more environmental surveillance sensors; validating the second set of spectra to be from the same source material as the first set of anomalous spectra; and replacing the synthetic entry with the second set of spectra for the unknown material in the particle spectra library.

Abstract: Disclosed herein are systems, devices and methods for detection, identification and sorting of cells and/or cellular-associated targets. The system comprises at least a microfluidic device and a Raman detection and identification unit. The microfluidic device comprises a junction structure aligned with the Raman detection and identification unit, wherein a cell confined at the junction structure is detected and analyzed by the Raman detection and identification unit and routed into a collection channel based on analysis of Raman spectra.

Abstract: Supercritical water oxidation (SCWO) is a destruction technology to quickly treat per- and polyfluoroalkyl substance (PFAS)-impacted groundwater, investigation derived waste, and other aqueous matrices such as landfill leachate and aqueous film forming foam. Laboratory-prepared and field-collected samples with inlet PFAS concentrations up to 50 parts per million were consistently destroyed to less than 70 parts per trillion for all PFAS, when running at the determined optimal operating conditions (?600° C. and 3,500 pounds per square inch). We investigated the correlation between temperature and flowrate of the system, finding that reactor temperatures ?450° C. destroys perfluorinated carbonic acids, but higher temperatures and specified conditions are necessary to destroy perfluorosulfonic acids. Using a higher density oxygen source also increases the throughput of a SCWO reactor, here up to 140 mL/min, without affecting PFAS destruction. Continuous 5-log reduction in the concentration of PFAS (99.

Abstract: An apparatus for extracting a material from a liquid includes a concentration stage having a filter, a first path from the filter, and a second path from the filter. Under this configuration, the concentration stage accepts an initial liquid volume. A first liquid not having material collected by the filter is passed along the first path, and concentrated liquid having material therein, which is entrapped by the filter, is directed to the second path. The apparatus also includes an aerosolizing stage coupled to the concentration stage that converts the concentrated liquid into an aerosol and a drying stage that dries the aerosol such that material extracted from the aerosol onto a material substrate.

Abstract: An apparatus for extracting a material from a liquid includes a concentration stage having a tangential flow filter, a first path from the tangential flow filter, and a second path from the tangential flow filter. Under this configuration, the concentration stage accepts an initial liquid volume. A first liquid not having material collected by the tangential flow filter is passed along the first path, and concentrated liquid having material therein, which is entrapped by the filter, is directed to the second path. The apparatus also includes an aerosolizing stage coupled to the concentration stage that converts the concentrated liquid into an aerosol and a drying stage that dries the aerosol such that material extracted from the aerosol onto a material substrate.
