摘要:
Provided are an emulsion comprising graphene oxide, a first fluid and a second fluid, and a drug delivery system comprising the emulsion. This emulsion is based on the discovery that graphene oxide is an amphiphile with hydrophilic edges and a more hydrophobic basal plane, and thus graphene oxide can act as a surfactant. Since the degree of ionization of the edge —COOH groups of the graphene oxide is affected by pH, the amphiphilicity of graphene oxide can be adjusted based on pH. Therefore, a method of separating a first liquid from a second liquid by providing an emulsion comprising graphene oxide, the first liquid and the second liquid is also provided. It was also discovered that graphene oxide can act as a molecular dispersing agent to process insoluble materials. Based on this discovery, a composition comprising graphene oxide, a solvent and an insoluble solid is provided.

A protocol identification method and a protocol identification device are provided. The protocol identification method includes acquiring a performance index of protocol characteristic information according to characteristic conditions of the protocol characteristic information; calculating identification probabilities of the protocol characteristic information employed by DPI under a preset statistical strategy according to a DPI identification result; determining an optimal sequence of all protocol characteristic information in a DPI identification library according to the performance index and the identification probabilities of the protocol characteristic information; and performing protocol identification on a received message according to the optimal sequence. The optimal sequence for protocol identification is determined according to the identification probabilities, the protocol characteristic information with a high match success probability may be matched first, and the protocol characteristic information with a high match failure probability may be matched later, which thereby improves the protocol match performance.
摘要:
Polymer nanofibers, such as polyaniline nanofibers, with uniform diameters less than 500 nm can be made in bulk quantities through a facile aqueous and organic interfacial polymerization method at ambient conditions. The nanofibers have lengths varying from 500 nm to 10 μm and form interconnected networks in a thin film. Thin film nanofiber sensors can be made of the polyaniline nanofibers having superior performance in both sensitivity and time response to a variety of gas vapors including, acids, bases, redox active vapors, alcohols and volatile organic chemicals.
摘要:
The welding of certain polymeric nanofibers can be accomplished by exposure to an intense short burst of light, such as is provided by a camera flash, resulting in an instantaneous melting of the exposed fibers and a welding of the fibers where they are in contact. The preferred nanofibers are composed of conjugated, conducting polymers, and derivatives and polymer blends including such materials. Alternatively, the nanofibers can be composed of colored thermoplastic polymeric fibers or opaque polymers by proper selection of the frequency or frequency range and intensity (power) of the light source. The flash welding process can also be used to weld nanofibers which comprise a blend of polymeric materials where at least one of the materials in the blend used to form the nanofiber is a conductive, conjugated polymer or a suitable colored thermoplastic. Alternatively the material blend used to form the nanofibers may comprise a polymeric material containing a colored additive, which is not necessarily a polymer, for example carbon black, or a colored nano-particulate organic or inorganic material, dye or pigment.
