    摘要： Recovery of noble metals (including the recovery of gold and/or silver from gold and/or silver containing material) is generally described. The gold and/or silver can be recovered selectively, in some cases, such that gold and/or silver are at least partially separated from non-silver and/or non-gold material. Gold and/or silver may be recovered from material using mixtures of acids, in some instances. In some cases, the mixture can comprise nitric acid and at least one supplemental acid, such as sulfuric acid, phosphoric acid, and/or a sulfonic acid. The amount of nitric acid within the mixture can be, in some instances, relatively small compared to the amount of sulfuric acid or phosphoric acid within the mixture. In some cases, the recovery of gold and/or silver using the acid mixtures can be enhanced by transporting an electric current between an electrode and the gold and/or silver of the material. In some cases, acid mixtures can be used to recover silver from particular types of materials, such as material comprising silver metal and cadmium oxide and/or material comprising silver metal and tungsten metal.

    摘要： A biosensor having somatic cells immobilized on an electrode formed from a biologically inert material for sensing transepithelial/transendothelial electrical resistance is provided. The biosensor includes a working electrode formed from gold, graphene, carbon nanotube, or alloys or combinations thereof, having somatic cells formed directly thereon. With such a configuration, a very small sample size may be used while still eliciting an electrical response in the presence of a target composition.

    摘要： The present invention relates to a self-assembly preparation method of a nanocomposite material, and more particularly, relates to a self-assembly preparation method of a nanocomposite material comprising steps of: spraying a drug-containing solution onto metal aerosol nanoparticles to form a drug layer on the metal aerosol nanoparticles; and spraying a polymer-containing solution onto the metal aerosol nanoparticles, on which the drug layer is formed, to form a polymer layer on the drug layer, whereby since the method involves no liquid chemical process upon producing the metal aerosol nanoparticles, the processes are simple and can be performed even at a low temperature to suppress deformation of an organic or a drug, and the release rate of the drug, or the like can be easily controlled through metal types of metal aerosol nanoparticles, modification, and the like.
