An apparatus includes a plurality of islands each carrying multiple cantilevers. The apparatus also includes a fluidic network having a plurality of channels separating the islands. The channels are configured to provide fluid to the islands, and the fluid at least partially fills spaces between the cantilevers and the islands. Heat from the islands vaporizes the fluid filling the spaces between the cantilevers and the islands to transfer the heat away from the islands while driving the cantilevers into oscillation. The apparatus may also include a casing configured to surround the islands and the fluidic network to create a vapor chamber, where the vapor chamber is configured to retain the vaporized fluid. The islands and the fluidic network could be formed in a single substrate, or the islands could be separate and attached together by a binder located within the channels of the fluidic network.

A chip-scale ion-trap mass spectrometer driven by a monolithic photodiode array and a method of fabricating the same. A high-voltage photovoltaic source is located in proximity to the ion-trap mass spectrometer structure. The high-voltage photovoltaic source includes monolithically fabricated and serially connected photodiodes. An external light source illuminates the photodiodes to generate a high voltage across the photodiode array. An RF voltage modulation is attained by modulating the light source at a desired RF frequency. The high-voltage photodiode array may be monolithically fabricated in association with the ion-trap mass spectrometer. The photodiode array requires a small area compared to the ion-trap mass spectrometer size as the spectrometer typically possess a very small capacitance and a low power consumption.

A radial turbomolecular pump comprising an electrostatically levitated rotor with a high compression ratio and pump speed at a chip-scale level. The levitated rotor can be sandwiched between a stator plate and a driver and multiple concentric rings of microblades can be fabricated on the rotor plate and the stator plate. The center portions of the driver and the base plate include concentric ring electrodes for rotor levitation by electrostatic forces. The space between two concentric rings of microblades forms a groove that is wide enough to receive the microblades from the opposing disk. The stator disk can be fixed and the rotor disk spins such that the rotor microblades move tangentially relative to the stator microblades. The microblades can be tilted at an angle from the tangent, facilitating momentum transfer to gas molecules in the radial direction.

An air scrubber, system, and method of use are provided. The air scrubber includes an electrospray nozzle for creating an ionic fluid electrospray plume; an air sample intake positioned to provide an air sample interacting with the ionic fluid electrospray plume; and a counter electrode positioned to collect the electrospray plume. The selected chemicals in the air sample are captured by ionic fluid electrospray plume and accumulate on the counter electrode.

A method includes acquiring a chemical sample and modulating the chemical sample at a frequency greater than a drift frequency of a sensor. The method also includes determining at least one of a presence and a concentration of the analyte within the modulated chemical sample using the sensor. Modulating the chemical sample could include alternately absorbing at least some of the analyte into a sorbent material and releasing at least some of the analyte from the sorbent material. Modulating the chemical sample could also include heating the sorbent material, absorbing part of the analyte into the sorbent material, and passing a remaining portion of the analyte into the sensor. Modulating the chemical sample could further include stopping the heating of the sorbent material, releasing the part of the analyte from the sorbent material, and passing the sample with the released part of the analyte into the sensor.

A blowerless heat exchanger apparatus based on micro-jet entrainment is disclosed. The heat exchanger apparatus incorporates a number of fins regularly spaced apart from each other and parallel to each other, thus letting air currents flow in the space defined between them. A dense array of micro-jet nozzles can be fabricated on the fins surface pointing to the flow direction of the air movement in order to induce increase airflow. The air from an air compressor delivers sufficient airflow on the fins surface utilizing micro-jets entrainment. The micro-jet entrainment confirms strong turbulent around the micro-jets and suggests significant heat transfer enhancement. The turbulence from the micro-jets enhance the heat transfer coefficient, potentially by an order of magnitude, therefore allowing much larger fin spacing and leads to huge reduction of flow resistance and overall power consumption.
