    Abstract: Contaminant-sequestering coatings include a network of hydrolyzed silane compounds including (i) a plurality of fluorinated functionalities, and (ii) a plurality of thiol functional groups are provided. The network of hydrolyzed silane compounds includes a fluorinated silane including (a) a hydrophilic polar head region. The polar head region includes one or multiple units of ethylene glycol (EG) functionality, (b) a fluorine-containing region, and (c) an anchor region including a silicon atom. The contaminant-sequestering coatings may sequester one or more per- and polyfluoroalkyl substances (PFAS), heavy metals, biological species, or any combination thereof.

    Abstract: Contaminate-sequestering coatings including a network of hydrolyzed silane compounds including a plurality of thiol functional groups, a plurality of fluorinated functionalities, or both are provided. The contaminate-sequestering coatings may sequester one or more per- and polyfluoroalkyl substances (PFAS), heavy metals, biological species or any combination thereof. Methods of functionalizing a substrate surface with contaminate-sequestering functionalities that sequester one or more PFAS, heavy metals, or both are also provided. Methods of removing contaminants from contaminate-containing liquids, and devices including the contaminate-sequestering coatings are also provided.

    Abstract: A sensor for measuring ocean water salinity is described. The sensor may include a measurement clock circuit, a control clock circuit, and a comparator circuit. The measurement clock circuit, having an output that varies with salinity of a fluid, may have a first circuit architecture that includes a capacitive gap assembly that permits a fluid to flow into a gap between two electrodes of the capacitive gap assembly. The control clock circuit, having an output that does not vary with salinity of the fluid, may have a second circuit architecture comprising a capacitor. The comparator circuit may be configured to compare the controlled clock output to the measured clock output over a duration of time to determine a salinity measurement of the fluid. The first circuit architecture may differ from the second circuit architecture in that an electrically connected position of the capacitive gap assembly within the first circuit architecture is the electrically connected position of the capacitor within the second circuit architecture.
