Patent number: 11469077Abstract: A microwave plasma chemical vapor deposition device for diamond synthesis. A microwave source generates a microwave signal, and a resonant cavity receives a plurality of process gases. The microwave signal is spread in a first mode at a first waveguide. A mode conversion antenna converts the first mode of the microwave signal into a second mode that is spread at a second waveguide. A coupling conversion cavity receives and transmits the microwave signal in the second mode to the mode conversion antenna thereby converting the second mode of the microwave signal into a third mode. A medium viewport receives the microwave signal in the third mode and transmits to the resonant cavity which enables the microwave signal to excite and discharge the process gases to form spherical plasma, carbon containing groups and atomic hydrogen thereby depositing a diamond film on a seed.Type: GrantFiled: April 22, 2019Date of Patent: October 11, 2022Assignee: FD3M, Inc.Inventors: Yi Ma, Matthew L.

Publication number: 20200025672Abstract: A method for reducing and determining coefficient of friction of a mycelium for improving a plurality of mechanical properties of the mycelium. In the method, a first mycelium layer is contacted with an abrasive and pressure apparatus for smoothing and altering a microstructure of the mycelium. The smoothing of the mycelium microstructure reduces the coefficient of friction of the mycelium thereby enhancing the abrasion resistance of the mycelium. The coefficient of friction of the mycelium surface reduced through smoothing of the mycelium surface is determined utilizing a tilt angle mechanism.Type: ApplicationFiled: July 19, 2019Publication date: January 23, 2020Inventors: Matthew L.
