Abstract: Provided are catalytic assemblies which include a hollow fiber membrane permeable to a gas; a reactive coating permeable to the gas and a contaminant; and a plurality of catalytic nanoparticles embedded in the reactive coating adapted to catalyze a reaction between the gas and the contaminant. Also provided are preparation methods for the catalytic assemblies, and use thereof for treating contaminated water.

Abstract: Methods to form a surface coating and surface pattern, which are based on adsorption of hydrocarbon chains that can be used with imaging optics to visualize macrophage fusion and multinucleated giant cell formation with living specimens are described.

Abstract: An electronic switch apparatus, a capacitive strain gauge apparatus and a nozzle apparatus, as well as methods for making electrodes such as liquid metal pipes are provided. A nozzle apparatus includes (a) a nozzle housing defining a cavity, where the nozzle housing defines an inlet at a first end and defines an outlet at a second end and (b) a first tube defining an inlet at a first end and defining an outlet at a second end, wherein the first tube is at least partially disposed in and is co-axially arranged with the nozzle housing, where the first tube defines a first flow channel, wherein a second flow channel is defined between an exterior surface of the first tube and an interior surface of the nozzle housing.

Abstract: A water treatment system including: a flow regulation control system configured to combine oxo-anion-contaminated water with a reduction-promoting agent, a hole scavenger, or both; a reactor fluidically coupled to the flow regulation control system; a first set of system control probes configured to monitor the concentration of oxygen and oxo-anion in the contaminated water; a second set of system control probes configured to monitor concentration of the oxo-anion and reduction products of the oxo-anion in treated effluent from the reactor; and a controller configured to control the flow regulation control system, thereby controlling the flow rate of the contaminated water and the at least one of the reduction-promoting agent and the hole scavenger to the reactor based at least in part on the concentration of oxo-anion and the reduction products of the oxo-anion in the treated effluent.
