Latest Patents
One of his latest patents is the "Neodymium gallate surface barrier for melt-processed YBa2Cu3Ox conductor with nickel sheath." This innovative process allows for the creation of a neodymium gallate (NGO) surface layer on the inside of a nickel sheath surrounding a core of yttrium-based copper oxide (YBCO) superconductor material. This surface layer acts as a diffusion barrier, preventing nickel from diffusing into the YBCO during high-temperature melt-processing. The method involves applying the NGO by slurry casting to a flat strip of solid nickel, which is then sintered at temperatures above 1000°C. This process ensures that the NGO remains chemically stable during subsequent melt-processing, ultimately leading to the manufacture of high-performance superconducting wire and tape.
Another significant patent is the "Cryogenic wound rotor for lightweight, high voltage generators." This invention utilizes liquid hydrogen to cool all components of the generator, including bearings and conductors. By immersing the generator in liquid hydrogen, cryogenic interface problems are minimized. The design employs pure metals like aluminum to reduce weight and ohmic heat loss. This innovative approach eliminates complications associated with liquid helium cooling and allows for the generation of very high voltages without the need for iron in the generator.
