    摘要： A method of purifying a metal nanostructure composition containing desired nanostructures and undesired nanostructures. The method includes providing a solution within which metal nanostructures have been synthesized including desired and undesired nanostructures. The solution includes polyol and has a viscosity. The method includes diluting the solution with a dilutant to lower the viscosity of the solution and provide a diluted solution. The method includes sedimenting the undesired nanostructures from the diluted solution. The method includes collecting the supernatant with the desired nanostructures and retaining the undesired nanostructures inside the sedimentation device. In an example, such is via a sedimentation device, which is a special tray system designed with grooved bottoms to retain the undesired nanostructures.

    摘要： A method includes supplying a supersaturated brine stream having a plurality of minerals and anti-scalant from a water treatment system to a gypsum removal system disposed within a mineral removal system. The gypsum removal system includes a gypsum reactor that may receive the supersaturated brine, may deactivate the anti-scalant such that gypsum precipitates from the supersaturated brine, and may generate a gypsum slurry having a mixture of desupersaturated brine, precipitated gypsum, and the anti-scalant in solution with the desupersaturated brine. The method also includes supplying gypsum seed crystals to the gypsum reactor. The gypsum seed crystals may precipitate the gypsum from the supersaturated brine to generate the gypsum slurry. The method also includes directing a first portion of the gypsum slurry from the gypsum reactor to a gypsum settler. The gypsum settler may reactivate the anti-scalant such that the anti-scalant absorbs onto the precipitated gypsum to remove the anti-scalant from the desupersaturated brine and may generate anti-scalant-gypsum crystals and a desupersaturated overflow having at least a portion of the plurality of minerals. The method further includes generating the gypsum seed crystals supplied to the gypsum reactor using the anti-scalant-gypsum crystals.

    摘要： A silver particles manufacturing method comprises following steps: providing a silver containing compound; providing an organic solution; adding the silver containing compound into the organic solution, to perform ultrasonic vibrations or a heating process until the silver containing compound is dissolved completely into the organic solution, to form a silver ion solution; performing the ultrasonic vibrations or the heating process, and then let the solution settle down for a period, to form a silver particles synthesized solution; and placing the silver particles synthesized solution into a centrifuge to perform centrifugation and separation, to obtain μm-scale silver particles and nm-scale silver particles. The silver particles manufacturing method has the advantages of low pollution, low cost, high yield, and mass production.

    摘要： A method of separating carbon nanotubes by electronic type includes centrifuging a carbon nanotube composition in contact with a first fluid medium comprising a first density gradient; and separating the carbon nanotube composition into two or more separation fractions. The carbon nanotube composition comprises two or more non-ionic amphiphilic surface active components and a carbon nanotube population comprising double-walled carbon nanotubes having a semiconducting outer wall (s-DWCNTs), and double-walled carbon nanotubes having a metallic outer wall (m-DWCNTs). The two or more separation fractions comprise a first separation fraction comprising a carbon nanotube subpopulation comprising a higher percentage of s-DWCNTs than the carbon nanotube population, and a second separation fraction comprising a carbon nanotube subpopulation comprising a higher percentage of m-DWCNTs than the carbon nanotube population.

    摘要： A method for transferring beads in a fluidic chip having an internal fluid circuit through which various reactants, including beads, may be moved by use of centrifugal force includes providing beads having a density equal to, or lower than, m1 in a section of the fluid circuit, where the section includes at least a first outlet. The method includes providing a first liquid medium having a density d2 to the section, such that d2>m1, and applying a centrifugal force such that the beads migrate in an opposite direction of the centrifugal force.
