Patent number: 11766507Abstract: A new insight on the lubrication of artificial joint components is presented. Addition of small amounts of nanoscale diamond particles to an artificial joint promotes a substantial improvement in friction and wear behavior of the artificial joint surfaces. Artificial joint implants are made from a variety of materials ranging from metal alloys to polymers. Suitable methods of applying nanoscale diamond particles to an artificial joint include (i) coating an effective amount of nanoscale diamond particles onto the artificial joint prior to implants; (ii) applying a composition to the artificial joint during an artificial joint implanting surgery, wherein said composition comprises a biocompatible carrier fluid and an effective amount of nanoscale diamond particles dispersed in the biocompatible carrier fluid; (iii) injecting the composition for lubricating the artificial joint into the artificial joint.Type: GrantFiled: September 9, 2020Date of Patent: September 26, 2023Assignee: University of North TexasInventors: Diana Berman, Donghui Zhu, Olga Shenderova

Patent number: 11232241Abstract: A method for designing new materials for superlubricity comprises developing, on a computational system, a computational supercell comprising x unit cells of a base material, each unit cell comprising y atoms of the base material. The computational system replaces randomly chosen z atoms of the base material with an impurity atom of an impurity material to form a candidate material. The computational system determines volumetric strain of the candidate material. In response to the volumetric strain exceeding a predetermined threshold, the computational system determines that the candidate material has superlubricity. The computational system displays the candidate material to a user if the candidate material has superlubricity.Type: GrantFiled: July 16, 2018Date of Patent: January 25, 2022Assignee: UChicago Argonne, LLCInventors: Badri Narayanan, Subramanian Sankaranarayanan, Anirudha V.
