Abstract
A microfluidic control apparatus, such as a relief valve, includes a pressure containing housing to contain a fluid within an interior of the pressure containing housing, and a nanotube in fluid communication between the interior of the pressure containing housing and an exterior of the pressure containing housing. The nanotube is used to contain water therein such that, below a predetermined temperature, the water within the nanotube prevents pressure relief through the nanotube from the interior to the exterior of the pressure containing housing, and above the predetermined temperature, the water within the nanotube enables pressure relief through the nanotube from the interior to the exterior of the pressure containing housing.
