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

Publication number: 20210371741Abstract: A method of controlled production of luminescent diamond particles exhibiting luminescence in selected specific spectral ranges is provided. The method comprises taking diamond particles containing dopant atoms in the diamond core, irradiating the particles with high energy radiation, and annealing the irradiated diamond particles at a target temperature in the temperature range of about 1400° C.-2200° C. to form luminescent diamond particles where the specific spectral range of luminescence is controlled by the target temperature of the annealing process, the irradiation dose, and the type of dopant atoms. Duration of the annealing and the temperature ramp up and ramp down times should be short enough to minimize or prevent significant graphitization of the particles. Duration of the temperature ramp up time should be short enough to minimize formation of color centers that might form at temperatures below the target temperature.Type: ApplicationFiled: April 19, 2021Publication date: December 2, 2021Inventors: Olga A.

Publication number: 20080067494Abstract: A field emitter device consistent with certain embodiments has a substantially planar conductor forming a gate electrode. A conductive stripe forms a cathode on the insulating layer. An insulating layer covers at least a portion of the surface between the cathode and the gate. An anode is positioned above the cathode. An emitter structure, for example of carbon nanotubes is disposed on a surface of the cathodes closest to the anode. When an electric field is generated across the insulating layer, the cathode/emitter structure has a combination of work function and aspect ratio that causes electron emission from the emitter structure toward the anode at a field strength that is lower than that which causes emissions from other regions of the cathode.
