摘要： Embodiments of the present invention relate to methods for preparing high optical density solutions of nanoparticle, such as nanoplates, silver nanoplates or silver platelet nanoparticles, and to the solutions and substrates prepared by the methods. The process can include the addition of stabilizing agents (e.g., chemical or biological agents bound or otherwise linked to the nanoparticle surface) that stabilize the nanoparticle before, during, and/or after concentration, thereby allowing for the production of a stable, high optical density solution of silver nanoplates. The process can also include increasing the concentration of silver nanoplates within the solution, and thus increasing the solution optical density.

摘要： A composite high-temperature proton exchange membrane for a fuel cell is prepared using materials include PBI and composite A@B and phosphoric acid. A is nanoparticles with a free radical quenching function and B is C3N4 having a nanosheet structure. The mass fraction of composite A@B is 0.05-2 wt. % and the mass ratio of A to B in A@B is 1:1-1:20. Composite A@B is firstly prepared, and A@B is then ultrasonically dispersed with a strong polar aprotic solvent to obtain a dispersion S1. PBI solution S2 is obtained from PBI and a strong polar aprotic solvent. S1 and S2 are uniformly mixed and stirred to obtain a casting solution S3, which is cast on plate glass with a groove. The membrane is then soaked in phosphoric acid after dying to obtain a composite membrane for a high-temperature proton fuel cell.

摘要： An additive for resin kneading contains an organic ultraviolet absorber and/or a radical scavenger, and a polymer having the organic ultraviolet absorber and/or the radical scavenger dispersed. The additive for resin kneading has a median size of 1 µm or more and 100 µm or less. A percentage of the total amount of the organic ultraviolet absorber and the radical scavenger in the additive for resin kneading is 20% or more and 70 % or less. The polymer is a copolymer of a vinyl monomer component that contains a monofunctional vinyl monomer containing only one polymerizable carbon-carbon double bond per molecule, and a polyfunctional vinyl monomer containing two or more polymerizable carbon-carbon double bonds per molecule. A percentage of the monofunctional vinyl monomer in the total amount of the monofunctional vinyl monomer and the polyfunctional vinyl monomer is 10% or more and 95% or less.

摘要： Polystyrene waste, such as Styrofoam® waste, and carbon nanofibers may be used to produce highly hydrophobic compositions or composites that can separate oil and water. Methods for purifying an aqueous solution may include: passing the aqueous solution, including a hydrophobic organic substance, over or through a surface including a polystyrene-CNF composition, thereby producing an aqueous product including less of the hydrophobic organic substance; and optionally, passing the aqueous product over or through the surface at least one more time.
