Patent number: 11785866Abstract: A superconductor device includes a high superconductivity transition temperature enhanced from the raw material transition temperature. The superconductor device includes a matrix material and a core material. The enhancing matrix material and the core material together create a system of strongly coupled carriers. A plurality of low-dimensional conductive features can be embedded in the matrix. The low-dimensional conductive features (e.g., nanowires or nanoparticles) can be conductors or superconductors. An interaction between electrons of the low-dimensional conductive features and the enhancing matrix material can promote excitations that increase a superconductivity transition temperature of the superconductor device.Type: GrantFiled: February 5, 2019Date of Patent: October 10, 2023Inventors: Philipp Braeuninger-Weimer, Nathan P.

Patent number: 8317983Abstract: Single walled carbon nanotubes are produced in a novel apparatus by the laser-induced ablation of moving carbon target. The laser used is of high average power and ultra-fast pulsing. According to various preferred embodiments, the laser produces and output above about 50 watts/cm2 at a repetition rate above about 15 MHz and exhibits a pulse duration below about 10 picoseconds. The carbon, carbon/catalyst target and the laser beam are moved relative to one another and a focused flow of “side pumped”, preheated inert gas is introduced near the point of ablation to minimize or eliminate interference by the ablated plume by removal of the plume and introduction of new target area for incidence with the laser beam. When the target is moved relative to the laser beam, rotational or translational movement may be imparted thereto, but rotation of the target is preferred.Type: GrantFiled: April 2, 2010Date of Patent: November 27, 2012Assignee: Jefferson Science Associates, LLCInventors: Brian C.
