Title: The Innovations of Nan Chen
Introduction
Nan Chen is a notable inventor based in Downers Grove, IL (US). He has made significant contributions to the field of superconductors, holding a total of 3 patents. His work focuses on advanced manufacturing techniques that enhance the properties of high-temperature superconductors.
Latest Patents
One of Nan Chen's latest patents is titled "Surface texturing of superconductors by controlled oxygen pressure." This innovative method involves creating a textured layer of a high-temperature superconductor on a substrate. The process begins with an untextured high-temperature superconductor material, which is heated to a temperature below its peritectic melting point. By establishing a reduced pO₂ atmosphere, the melting point is lowered, allowing for the controlled solidification of the molten superconductor into a textured surface layer. Another significant patent involves the synthesis of a (BiPb)₂Sr₂Ca₂Cu₃Oₓ (Bi223) superconductor, which boasts high critical current density, phase purity, density, and mechanical strength. This is achieved through a meticulous process of milling, drying, calcining, and sinter forging Bi2223 powder.
