Title: The Innovative Journey of Lawrence G. Duquette
Introduction
Lawrence G. Duquette, an esteemed inventor based in Maynard, MA, has made significant contributions to the field of materials science through his work at The Dow Chemical Company. With a remarkable portfolio of 15 patents, Duquette has shown a profound dedication to advancing technologies that harness the remarkable properties of complex compounds.
Latest Patents
One of Duquette's latest innovations involves the preparation of ABO3 compounds from mixed metal aromatic coordination complexes. The patented methods detail a process where compounds serving as a source of the B metal ion react with substituted aromatic compounds in a solution. Following this, the resulting metal coordination complex is reacted with a source of the A metal ion, also in solution. A specific example of this includes the reaction of titanium tetraisopropoxide with catechol to create a titanium catecholate coordination complex. This complex is further treated with barium hydroxide octahydrate to form a pentamethanol barium triscatecholatotitanate mixed metal coordination complex. When calcined at elevated temperatures, this process yields the ABO3 compound known as barium titanate (BaTiO3), celebrated for its outstanding dielectric, ferroelectric, and piezoelectric properties. Additionally, the invention allows for the substitution of portions of the A and/or B ions with other metals, broadening the scope of its applications.
