Introduction

David Lewis, III is a notable inventor based in Alexandria, VA (US). He has made significant contributions to the field of materials science, particularly in the development of innovative methods for joining and synthesizing materials. With a total of 5 patents to his name, Lewis continues to push the boundaries of technology.

Latest Patents

One of his latest patents is titled "Microwave Assisted Reactive Brazing of Ceramic Materials." This method focuses on joining similar materials to create multi-component assemblies that share physical, chemical, and electrical characteristics with the base materials. The process involves aligning the materials, applying a joining material, and using a microwave beam to heat the joint area, allowing the joining material to soften and fill physical discontinuities while keeping the surrounding surfaces cool. The method then rapidly heats the joint area to the reactive area of the joining material, followed by rapid cooling and maintaining the joint area at a recrystallization temperature. The materials used can include ceramics such as aluminum oxide.

Another significant patent is "Microwave Assisted Continuous Synthesis of Nanocrystalline Powders and Coatings Using the Polyol Process." This method involves forming a nanocrystalline metal by providing a reaction mixture that includes a metal precursor and an alcohol solvent. The mixture is continuously flowed through a reactor while applying microwave or millimeter-wave energy localized to the reaction mixture. The heating process allows the alcohol solvent to reduce the metal precursor to a metal within the reactor.
