  • Patent number: 8877505
    Abstract: Embodiments of a composition for stabilizing fluorescent signal of nanoparticles and methods for its use are disclosed. In some embodiments, the composition has a pH from 7 to 10 and includes borate, protein and/or protein hydrolysate, an amine, a preservative, and a nonionic surfactant. In particular embodiments, the amine is an N-ethanol substituted amine, such as ethanolamine, diethanolamine, triethanolamine, N-methyldiethanolamine, N,N-dimethylethanolamine, or a combination thereof. In some embodiments, a fluorescent particle solution, such as a quantum dot solution or quantum dot conjugate solution, is diluted in the composition and stored at 4° C. In certain embodiments, the fluorescence intensity of the diluted fluorescent particle remains substantially the same when stored at 4° C. for at least one month or at least three months. In particular embodiments, a diluted quantum dot conjugate is used to detect a hybridized probe or a protein antigen.

  • Patent number: 8865501
    Abstract: The object of the present invention is to provide a method of fabricating a thermoelectric material and a thermoelectric material fabricated thereby. According to the present invention, since carbon nanotubes with no surface treatment are dispersed in the alloy, electrical resistivity decreases and electrical conductivity increases in comparison to surface-treated carbon nanotubes and an amount of thermal conductivity decreased is the same as that in the case of using surface-treated carbon nanotubes, and thus, a ZT value, a thermoelectric figure of merit, is improved. A separate reducing agent is not used and an organic solvent having reducing powder is used to improve economic factors related to material costs and process steps, and carbon nanotubes may be dispersed in the thermoelectric material without mechanical milling.

  • Patent number: 8841231
    Abstract: The invention concerns a novel process for the preparation of supported metallic catalysts in which the metallic phase is deposited in the form of agglomerates of nanoparticles of metallic oxide and forms a layer of fine thickness at the surface of the support. The process for the preparation of a catalyst comprises preparing in aqueous phase a colloidal suspension of agglomerates of nanoparticles of metallic oxide, then depositing that suspension on a porous support, drying the catalyst precursor obtained, and optionally calcining and reducing the precursor by means of any reducing compound. The invention also concerns the catalysts obtained by said process and their uses in reactions for the transformation of unsaturated organic compounds. The invention is applied to the refining field and more particularly to the treatment of gasolines obtained by steam cracking and/or obtained by catalytic cracking.

  • Patent number: 8815089
    Abstract: Nanoparticle-treated particle packs, such as sand beds, may effectively filter and purify liquids such as waste water. When tiny contaminant particles in waste water flow through the particle pack, the nanoparticles will capture and hold the tiny contaminant particles within the pack due to the nanoparticles' surface forces, including, but not necessarily limited to van der Waals and electrostatic forces. Coating agents such as alcohols, glycols, polyols, vegetable oil, and mineral oils may help apply the nanoparticles to the particle surfaces in the filter beds or packs.
