摘要： A cold-atom cell is formed by machining a block of silicon to define sites for an atom source chamber, an atom manipulation chamber, and an ion-pump chamber. A polished silicon panel is frit-bonded to an unpolished (due to machining) chamber wall (which would be difficult and costly to polish). The polished panel can then serve as a reflector or a sight for anodic bonding. A solid-phase atom source provides for vapor phase atoms in the source chamber. The source chamber also includes carbon and gold to regulate the atom pressure by sorbing and desorbing thermal atoms. The atom manipulation chamber includes components for magneto-optical trap and an atom chip, e.g., for forming a Bose-Einstein condensate. The ion-pump chamber serves as the site for an ion pump. By integrating the ion pump into the body of the cold-atom cell, a more compact, reliable, and robust cold-atom cell is achieved. In addition to the embodiment just described, several variations and alternatives are presented and within the scope of the claims.

摘要： Provided herein are passive microfluidic pumps. The pumps can comprise a fluid inlet, an absorbent region, a resistive region fluidly connecting the fluid inlet and the absorbent region, and an evaporation barrier enclosing the resistive region, the absorbent region, or a combination thereof. The resistive region can comprise a first porous medium, and a fluidly non-conducting boundary defining a path for fluid flow through the first porous medium from the fluid inlet to the absorbent region. The absorbent region can comprise a fluidly non-conducting boundary defining a volume of a second porous medium sized to absorb a predetermined volume of fluid imbibed from the resistive region. The resistive region and the absorbent region can be configured to establish a capillary-driven fluid front advancing from the fluid inlet through the resistive region to the absorbent region when the fluid inlet is contacted with fluid.

摘要： A compressor free, generator free system production well for accelerated oil and gas removal from a reservoir using a magnetically coupled expander pump assembly, which include an outer expansion turbine that rotates around a pump. A magnetic coupling couples the expansion turbine to the pump. An inner portion of the magnetic coupling can be coupled to a pump shaft that drives the pump. An outer portion of the magnetic coupling can be driven by the expansion turbine, which rotates circumferentially around the pump. The expansion turbine drives the fluid to pump a driven fluid stream through the magnetic coupling. In this manner, flow directions of both driving and driven fluid streams remain separate and coaxial, thereby facilitating a reduction in an overall diameter of the expander pump assembly.

摘要： Provided is a method for maintaining a preset air pressure of a low-pressure chamber. The method may comprise the steps of: measuring the inside air pressure of a low-pressure chamber; if the difference between the inside air pressure and a preset air pressure is the same or higher than a threshold value, adjusting the inside temperature of the low-pressure chamber by using a thermal conduction part disposed inside the low-pressure chamber; and by using a getter, making the difference to be below the threshold value by adsorbing or releasing molecules inside the low-pressure chamber according to the adjustment of the temperature
