摘要:
Nano-particles are molded in nano-scale molds fabricated from non- wetting, low surface energy polymeric materials. The nano-particles can include pharmaceutical compositions, taggants, contrast agents, biologic drugs, drug compositions, organic materials, and the like. The molds can be virtually any shape and less than 10 micron in cross-sectional diameter.
摘要:
Solid electrolyte compositions are described. The solid electrolyte compositions may include a composite including an inorganic solid electrolyte and an ion conducting fluoropolymer. A cation transference number of each of the inorganic solid electrolyte and the ion conducting fluoropolymer may be at least 0.9. The inorganic solid electrolyte may be bonded to the ion conducting fluoropolymer. Optionally, an alkali metal salt may be included in the solid electrolyte compositions. Batteries containing such solid electrolyte compositions are also described.
摘要:
The presently disclosed subject matter describes the use of fluorinated elastomer-based materials, in particular perfluoropolyether (PFPE)-based materials, in high-resolution soft or imprint lithographic applications, such as micro- and nanoscale replica molding, and the first nano-contact molding of organic materials to generate high fidelity features using an elastomeric mold. Accordingly, the presently disclosed subject matter describes a method for producing free-standing, isolated nanostructures of any shape using soft or imprint lithography techniques.
摘要:
Electrolyte compositions for batteries such as lithium ion and lithium air batteries are described. In some embodiments the compositions are liquid compositions comprising (a) a homogeneous solvent system, said solvent system comprising a perfluropolyether (PFPE) and polyethylene oxide (PEO); and (b) an alkali metal salt dissolved in said solvent system. In other embodiments the compositions are solid electrolyte compositions comprising: (a) a solid polymer, said polymer comprising a crosslinked product of a crosslinkable perfluropolyether (PFPE) and a crosslinkable polyethylene oxide (PEO); and (b) an alkali metal ion salt dissolved in said polymer. Batteries containing such compositions as electrolytes are also described.
摘要:
Methods of making fluoropolymers from at least one fluoromonomer in either (1) a heterogeneous medium comprising a carbon dioxide and an aqueous phase with or without hydrocarbon surfactants or dispersants or stabilizer, or (2) a homogenous medium containing carbon dioxide with one or more organic solvents, are described.
摘要:
Liquid or solid electrolyte compositions are described that comprise a homogeneous solvent system and an alkali metal salt dissolved in said solvent system. The solvent system may comprise a fluoropolymer, having one or two terminal carbonate groups covalently coupled thereto. Batteries containing such electrolyte compositions are also described.
