摘要： Quantifying nanobubbles in solution includes combining an indicator with a fluid comprising nanobubbles to yield a first solution, bursting the nanobubbles in the first solution to yield a second solution, and assessing a difference between the first solution and the second solution to yield a concentration of the nanobubbles in the first solution, a concentration of reactive oxygen species in the first solution or the second solution, or both.

摘要： A microfluidic device includes a sample inlet for a fluid sample, a degassing chamber having a gas-permeable membrane and defining first and second portions separated by the gas permeable membrane, and a detection chamber. The sample inlet and the detection chamber are fluidly coupled to the first and second portions, respectively of the degassing chamber. The detection chamber is operably coupled to a light source and a detector. Assessing a concentration of chlorine gas in an aqueous sample includes providing an aqueous sample to a microfluidic device, separating gas from the aqueous sample in the microfluidic device, providing the gas to a detector, assessing the absorbance of the gas sample at a known absorption wavelength of chlorine, and based on the assessed absorbance of the gas sample at the known absorption wavelength of chlorine, assessing a concentration of chlorine gas in the aqueous sample.

摘要： A photocatalytic reactor includes a polymeric side-emitting optical fiber having a coating with a photocatalyst embedded in a porous polymer, a light source optically coupled to the polymeric side-emitting optical fiber and configured to irradiate the photocatalyst, and a multiplicity of oxygen-permeable hollow-fiber membranes. The polymeric side-emitting optical fiber and the multiplicity of oxygen-permeable hollow-fiber membranes are configured to be at least partially immersed in water. When at least partially immersed in water, the multiplicity of oxygen-permeable hollow-fiber membranes is configured to provide dissolved molecular oxygen to the water, and the coating is configured to allow diffusion of the dissolved molecular oxygen into the coating and to allow diffusion of hydrogen peroxide out of the coating.

摘要： A coated optical fiber includes an optical fiber having a core and an outer surface, and a homogeneous polymer coating in contact with the outer surface of the optical fiber. The optical fiber and the homogeneous polymer coating are UV transparent, and a refractive index of the outer surface of the optical fiber or the homogeneous polymer coating is up to 15% less than a refractive index of the core. Coating the optical fiber includes coating an outer surface with a polymerizable material and polymerizing the polymerizerable material to yield the coated optical fiber having a homogeneous polymer coating. The optical fiber and the homogeneous polymer coating are UV transparent, and a refractive index of the outer surface of the optical fiber or the homogeneous polymer coating is up to 15% less than a refractive index of a core of the optical fiber.
