Latest Patents

One of Yuhua Ni's latest patents is a method of controlled synthesis of nanoparticles. This method involves the synthesis and manufacture of metal nanoparticles using metal inorganic salts. The process is straightforward and utilizes inexpensive chemicals, resulting in nanometals produced with 100% yields. The method is scalable, allowing for the production of nanoparticles in unlimited quantities. In this technique, a metal inorganic salt is dissolved in a reaction medium, which consists of a solvent and organic amine to create a metal/amine complex. A reducing agent, made up of a solvent and Sodium Borohydride (NaBH), is then mixed with the metal/amine complex through titration or a continuous flow process. The resulting nanoparticles are precipitated by adding methanol, followed by centrifugation and decantation. The decanted nanoparticles can be suspended in a solvent for storage.

Another notable patent by Ni is the controlled synthesis of nanoparticles using a continuous liquid-flow aerosol method. This method and apparatus for producing surface-stabilized nanometer-sized particles involves mixing reactants, a surface-stabilizing surfactant, and a high boiling point liquid to form a mixture. The mixture is continuously passed through an ultrasonic spray nozzle to create a mist of droplets, which is then injected directly into a furnace to initiate a reaction. This innovative approach eliminates the need for dilution with low boiling point solvents, significantly increasing yield and improving product quality while maintaining scalability.
