Patent number: 12040164Abstract: A barrierless device and method for generating streamer discharge is provided including solid/liquid electrodes for free radical generation at high efficiency. A first electrode, including periodically positioned discharge ignition tips is deposed in proximity to a second electrode, creating a discharge gap with no dielectric barrier layer in between. The discharge gap includes an inlet and an outlet. Streamers with proximity constraints emerge from the first electrode and propagate through the discharge gap towards the second electrode by supplying either positive or negative pulse voltage to the first electrode, resulting in interaction of the streamer heads with the discharge gas and generation of radicals. Optionally, the second electrode is a liquid which interacts with the streamer head to generate additional radicals. The device can either be used to cause fast chemical reaction within the discharge gap or the generated radical gas can be removed for utilization outside the discharge gap.Type: GrantFiled: April 22, 2022Date of Patent: July 16, 2024Assignee: Somnio Global Holdings, LLCInventors: Pravansu S.

Publication number: 20220134424Abstract: Provided are methods and devices for forming high nitrogen steel. The processes include heating a steel precursor to a temperature that transforms the steel into an austenite of FCC wherein the heating is in a nitrogen containing atmosphere. After an optional nitrogen uptake time, the precursor is further heated to a temperature above the T?N of the steel yet below the melting point of the steel thereby preserving a solid and creating a solid solution of nitrogen. The second temperature is optionally maintained for a nitride conversion time, optionally wherein the nitride conversion time is too short to result in sintering of the steel. The process further includes rapid quenching of the precursor powder to maintain the nitrogen solid solution and prevent nitride formation thereby forming a high nitrogen steel with little to no nitride content and including nitrogen in solid solution.Type: ApplicationFiled: February 26, 2020Publication date: May 5, 2022Applicant: Somnio Global Holdings, LLCInventors: Pravansu S.
