Bleach dilution and delivery vehicles are enabled. For example, a method can comprise: transporting, using a bleach dilution and delivery vehicle, sodium hypochlorite from a first location to a second location, mixing, using the bleach dilution and delivery vehicle, water from the second location and sodium hypochlorite from the bleach dilution and delivery vehicle to a defined strength, resulting in a diluted mix, and dispensing, using the bleach dilution and delivery vehicle, the diluted mix to the second location.

An improved method of preparing a carbon fiber-reinforced thermoplastic nonwoven web using recycled carbon fibers employs resonant acoustic mixing to combine the recycled carbon fibers with the thermoplastic fibers, followed by carding of the fiber mixture to form the carbon-fiber reinforced nonwoven web. The method provides a low-cost way to make carbon-fiber reinforced nonwoven webs that have sufficient mechanical properties to enable widespread use in the automotive industry and other high-volume industries.

A method for crystallizing calcium nitrate from an aqueous calcium nitrate composition including from 6 to 12 weight % nitric acid, from 11 to 17 weight % phosphoric acid, and from 36 to 49 weight % dissolved calcium nitrate, which aqueous composition is optionally directly obtainable from digesting phosphate rock in nitric acid. The method includes filling at least one vertical crystallizing tank through an inlet with the aqueous calcium nitrate composition. The crystallizing tank includes a vertical cylindrical section, a first inlet, a first outlet, a second inlet, three concentric banks of cooling coils, an agitator, and a temperature measurement device. The method includes circulating through the banks of cooling coils a cooling fluid, having an initial temperature ranging from 40 C. to 5 C., and rotating the agitator such that a minimum average heat transfer of 400 W/m.sup.2.Math.K is achieved on the cooling coil the most distant from the agitator.

The present subject matter further relates to a box-type portable flow rate metering device for measuring flow rate of multiple fluids of varied viscosities while being supplies to form a final mixture. The device includes a flow meter which is detachably arranged per feed line to measure a flow rate of respective fluid during each operation cycle; and a digital display unit coupled to the respective flow meter to display the flow rate of the respective fluid during each operation cycle.

Methods, spray devices, and kits for the in situ formation of silk fibroin fibers and/or aerosols are disclosed. Rapidly mixing a silk fibroin solution and a beta sheet initiation solution forms a mixed solution, which is rapidly expanded to form the silk fibroin fibers and/or aerosols. The beta sheet initiation solution includes a hygroscopic polymer having a molecular weight of between 7.5 kDa and 15.0 kDa. The rapid mixing and rapid expanding occur within one second of one another. Silk fibroin aerosols are formed when a molecular weight distribution of fragments in the silk fibroin solution is below an aerosol-fiber threshold. Silk fibroin fibers are formed when the molecular weight distribution is below the aerosol-fiber threshold.
