Title: Innovations of Kien-Yin Lee
Introduction
Kien-Yin Lee is a notable inventor based in Santa Fe, NM (US). He has made significant contributions to the field of energetic materials, holding 2 patents that showcase his innovative approaches to the preparation of nanopowders and fine-grained explosives.
Latest Patents
One of his latest patents is a method for forming energetic nanopowders. This method involves preparing a solution of a chosen energetic material in an aprotic solvent, which is then combined with liquid hexane. The process results in the formation of neat powders with nanometer dimensions. The energetic material is less soluble in hexane than in the aprotic solvent, and cooling the hexane below the solvent solution temperature facilitates the precipitation of the nanopowder. The resulting material can be dried and filtered to yield a high-quality energetic nanopowder.
Another significant patent by Kien-Yin Lee is the synthesis of fine-grained triamino-trinitrobenzene (TATB). This method enhances the detonation-spreading performance and shock sensitivity of TATB compared to ultrafine variants. The process utilizes a single-step, sonochemical amination of trichloro-trinitrobenzene with ammonium hydroxide in a sealed vessel, resulting in TATB with a median particle diameter of approximately 6 µm.
