  • Patent number: 10092661
    Abstract: In the present invention, a method of producing stable bare colloidal gold nanoparticles is disclosed. The nanoparticles can subsequently be subjected to partial or full surface modification. The method comprises preparation of colloidal gold nanoparticles in a liquid by employing a top-down nanofabrication method using bulk gold as a source material. The surface modification of these nanoparticles is carried out by adding one or multiple types of ligands each containing functional groups which exhibit affinity for gold nanoparticle surfaces to produce the conjugates. Because of the high efficiency and excellent stability of the nanoparticles produced by this method, the fabricated gold nanoparticle conjugates can have surface coverage with functional ligands which can be tuned to be any percent value between 0 and 100%.

  • Patent number: 9643842
    Abstract: At least one embodiment of the present invention provides preparation methods and compositions for nanoarchitectured multi-component materials based on carbon-coated iron-molybdenum mixed oxide as the electrode material for energy storage devices. A sol-gel process containing soluble organics is a preferred method. The soluble organics could become a carbon coating for the mixed oxide after thermal decomposition. The existence of the carbon coating provides the mixed oxide with an advantage in cycling stability over the corresponding carbon-free mixed oxide. For the carbon-coated mixed oxide, a stable cycling stability at high charge/discharge rate (3A/g) can be obtained with Mo/Fe molar ratios ?1/3. The cycling stability and rate capability could be tuned by incorporating a structural additive such as Al2O3 and a conductive additive such as carbon nanotubes. The high rate performance of the multi-component material has been demonstrated in a full device with porous carbons as the positive electrode material.

  • Patent number: 9587071
    Abstract: The present invention relates to methods, compositions, and kits for generating conjugated gold nanoparticles. In certain embodiments, the present invention provides methods of generating unsaturated conjugated gold nanoparticles by mixing naked gold nanoparticles with a first type of attachment molecules at a molar ratio such that the attachment molecules attach to the naked gold particles at a density level below the saturation level of the naked gold particles (e.g., at a saturation level of 1-99%). In some embodiments, a second type of attachment molecules (e.g., with the opposite charge as the first type of attachment molecules) are mixed with the unsaturated conjugated gold nanoparticles to generate double-conjugated gold nanoparticles (e.g., that are zwitterionic).

  • Publication number: 20150280227
    Abstract: A predoping method for a negative electrode active material of an energy storage device, comprising at least one predoping material that can provide an ion that is different from a primary ionic charge carrier for a charging and discharging process of the energy storage device, called non-primary predoping material. The predoping material may be first included in a predoping electrode and later discharged to the negative electrode active material. The predoping material may be first mixed with the negative electrode active material in an electrode fabrication process, and later made to directly contact the negative electrode active material by adding an electrolyte and removing the protective shells of the predoping material. An ion exchanging method is used to exchange a first ion coming from the predoping material for a second ion in an electrode stack.

  • Publication number: 20150258631
    Abstract: Disclosed is a method of producing a chemically pure and stably dispersed organic nanoparticle colloidal suspension using an ultrafast pulsed laser ablation process. The method comprises irradiating a target of an organic compound material in contact with a poor solvent with ultrashort laser pulses at a high repetition rate and collecting the nanoparticles of the organic compound produced. The method may be implemented with a high repetition rate ultrafast pulsed laser source, an optical system for focusing and moving the pulsed laser beam, an organic compound target in contact with a poor solvent, and a solvent circulating system to cool the laser focal volume and collect the produced nanoparticle products. By controlling various laser parameters, and with optional poor solvent flow movement, the method provides stable colloids of dispersed organic nanoparticles in the poor solvent in the absence of any stabilizing agents.
