Abstract: A method to quickly adjust the size of micelles and then return the micelles to a persistent state is provided. Specifically, the present invention is directed to a method for block copolymer micelle growth under high-χN solution conditions where ultrasonic cavitation facilitates rapid solution-gas interface production that accelerates micelle growth by an order of magnitude over other methods such as vortexing. The persistent micelles formed by the method of the present invention can then be used for controlled delivery of dispersions in organic electronic coatings, paint, or drug delivery applications and can also be used to control the pore size of films that include an oxide, a nitride, a carbide, a metal, or a carbon material.

Abstract: A renewable material for releasing a self-healing agent includes a renewable polymeric substrate with capsules and a reactant dispersed in the renewable polymeric substrate. The capsules may be formed from a first renewable shell polymer and may enclose the renewable self-healing agent. The reactant may be suitable for reacting with the renewable self-healing agent to form a polymer.

Abstract: The invention provides a nitrogen-doped graphene coated nano sulfur positive electrode composite material, a preparation method, and an application thereof. The composite material includes: an effective three-dimensional conductive network formed by overlapping of nitrogen-doped graphenes, and nano sulfur particles coated by nitrogen doped graphene layers evenly. The preparation method includes: dispersing nitrogen-doped graphenes in a liquid-phase reaction system including at least sulfur source and acid, and depositing nano sulfur particles by an in-situ chemical reaction of the sulfur source and the acid, thereby preparing the positive electrode composite material. The positive electrode composite material of the invention has a high conductivity, a high sulfur utilization rate, and a high rate, thereby restraining the dissolution and shuttle effect in the lithium sulfur batteries, and enhancing the cyclic performance of the batteries.

Abstract: Microcapsules are disclosed that have a core composition encapsulated within a polymer wall, and an inorganic shell connected to an exterior surface of the polymer wall by a surfactant. The inorganic shell has a cation attracted to the surfactant and an anion or anion equivalent chemically bonded to the cation to form the shell or has the metal portion of a metal-containing compound attracted to the surfactant to form the shell. The shell may comprise a Ca, Mg, or Ag metal compound. The shell may be a graphene oxide-metal compound.

Abstract: A water-phase composition for producing microparticles includes a water-phase fluid, an amphiphilic polymer stabilizing agent, a water-phase surfactant, and an organic solvent. The amphiphilic polymer stabilizing agent can be polyvinyl alcohol. The water-phase surfactant can be polysorbate 20, polysorbate 80, poloxamer 188, or sodium dodecyl sulfate. The water-phase surfactant can be ethyl acetate, dichloromethane, chloroform, or dimethyl sulfoxide.

Abstract: Embodiments of a display device including barrier layer coated quantum dots and a method of making the barrier layer coated quantum dots are described. Each of the barrier layer coated quantum dots includes a core-shell structure and a hydrophobic barrier layer disposed on the core-shell structure. The hydrophobic barrier layer is configured to provide a distance between the core-shell structure of one of the quantum dots with the core-shell structures of other quantum dots that are in substantial contact with the one of the quantum dots. The method for making the barrier layer coated quantum dots includes forming reverse micro-micelles using surfactants and incorporating quantum dots into the reverse micro-micelles. The method further includes individually coating the incorporated quantum dots with a barrier layer and isolating the barrier layer coated quantum dots with the surfactants of the reverse micro-micelles disposed on the barrier layer.
