Latest Patents
Among his latest inventions, Lee has developed a groundbreaking process for preparing energetic materials using sol-gel chemistry. This method allows for the preparation of explosives, propellants, and pyrotechnics with improved homogeneity and the ability to be cast into near-net shapes or precision molding powders. The sol-gel technique involves mixing reactive monomers into a solution, leading to polymerization and forming a cohesive gel structure. This process provides the ability to tailor various parameters such as composition, primary particle sizes, and density during production. The drying phase can be achieved through supercritical extraction or controlled slow evaporation, resulting in highly porous aerogels or dense xerogels, respectively. This innovation holds potential for precision detonator explosive manufacturing and the production of advanced energetic materials.
Another notable patent is his method for defining features on materials with a femtosecond laser. This invention relates to pulsed laser ablation for metals and dielectric films from substrate surfaces. By employing ultra-short, high-energy laser pulses, Lee's technique enables the manufacture of electronic circuits and electro-mechanical assemblies without damaging the surrounding material. This advanced manufacturing method is a testament to his contributions to precision engineering.
