Publication number: 20240083775Abstract: Water purification may occur by introducing sufficient heat into a standing fluid wave produced by supplying impure water into a supersonic gas stream. At least partially purified water may be recovered in the form of steam and undergo condensation into liquid water thereafter. Such water purification methods may comprise: generating a supersonic gas stream by feeding a gas through a shockwave nozzle under conditions sufficient to achieve a supersonic velocity, supplying impure water into the supersonic gas stream to produce a standing fluid wave comprising atomized water droplets downstream from an exit end of the shockwave nozzle, introducing sufficient heat into the standing fluid wave to cause at least a portion of the atomized water droplets to phase change into steam, and obtaining the steam as an overhead stream separated from an effluent stream containing one or more contaminants.Type: ApplicationFiled: January 19, 2022Publication date: March 14, 2024Applicant: NATURAL ENVIRONMENT R&D, LLCInventor: Brian TANG

Publication number: 20240080965Abstract: A method for producing a neutrons includes triggering a raising or a lowering of a temperature of a pyroelectric crystal of less than about 40° C. to produce a voltage of negative polarity of at least ?100 keV on a surface of a deuterated or tritiated target coupled thereto. A deuterium ion source is pulsed to produce a deuterium ion beam. The accelerating of the deuterium ion beam is achieved by accelerating voltage of the pyroelectric crystal toward the deuterated or tritiated target to produce neutrons. Furthermore, the pyroelectric crystal, the deuterated or tritiated target, and the deuterium ion source are coupled to a common support. The method also includes throwing the common support housing the pyroelectric crystal, the deuterated or tritiated target, and the deuterium ion source near an unknown threat for identification thereof.Type: ApplicationFiled: October 3, 2023Publication date: March 7, 2024Inventors: Vincent Tang, Glenn A.
