Abstract: Various embodiments of the present disclosure disclose methods and systems for heat exchange in an opto-fluidic instrument. The opto-fluidic instrument includes a sample interface module (SIM), an illumination module, a camera module, and a reagent deck. A coolant from a coolant reservoir is directed into one or more of the modules so that heat exchange occurs at each module with the coolant. The heated coolant from the one or more modules flows to a radiator for cooling, for example, with fans flowing ambient air over the radiator, before the cooled coolant is returned to the coolant reservoir for subsequent use in cooling the modules.

Abstract: The reaction between aluminum metal and water holds promise for producing hydrogen; however, solid aluminum metal is difficult to manage and use, and the reactivity between aluminum and water is often difficult to control. Certain embodiments of the disclosure are related to a water-stable aluminum slurry comprising a plurality of activated aluminum particles dispersed in a fluid carrier. In some embodiments, the reactivity of the aluminum slurry in the presence of water may be easily controlled with the addition of various additives (e.g., surfactants). Additionally, methods of making and using the water-stable aluminum slurry to controllable manage the reactivity between aluminum and water are presented herein.

Abstract: Systems and methods for producing mixed lifting gases (e.g., hydrogen gas and steam) for filling balloons are described. In some embodiments, controlling an altitude of a balloon includes combining a reactant and water to produce hydrogen gas and steam, and flowing the hydrogen gas and steam into the balloon to increase a buoyancy of the balloon.
