Abstract: Heat transfer devices and systems are provided for the rapid cooling of pulsed high-powered, high-flux devices using flash boiling. Such devices comprise at least two fluidly connected chambers and a heat exchanger in thermal communication with a heat source. A flash boiling event is actively triggered at a location close to the heat source by rapid depressurization of the chamber containing a multi-phase coolant. This boiling process allows for high heat transfer rates from the heat source into the chambers due to the latent heat of vaporization, which results in the rapid cooling of the heat source. A porous medium may also be positioned within a chamber of the device to enhance boiling nucleation and extended surface heat transfer. Methods of rapidly cooling pulsed heat sources are also provided using the devices and systems hereof.

Abstract: Aspects of the present disclosure involve systems, methods, and the like, for a fabrication of a particulate matter (PM) sensor that utilizes a capacitance sensor to detect sub-micrometer and nanoparticles in the respirable range of an environment. In one implementation, the capacitance sensor may comprise interdigitated electrodes between which a capacitance may be measured. PM deposited on the sensor may cause the capacitance between the electrodes to be altered and such a change in capacitance may be measured by the PM sensor. This measurement of the change in capacitance of the interdigitated capacitance sensor may therefore be correlated to the presence of sub-micrometer and nanoparticles in an environment. In one particular implementation, the PM sensor may further include a micro-heater circuit, a readout circuit, and an interface connecting the readout circuit to the micro-heater/capacitance sensor of the PM sensor.
