摘要： Compositions, methods, devices, and systems for purifying a source liquid from a replenishment stock solution that includes stabilizing agents, such as metal ions, prior to vaporization. Certain embodiments effect the purification with a solid perfluoronated ionomer, such as a perfluoronated ionomer membrane. Advantageously, source liquids purified in this manner provide feed stocks for production of ultra-pure gaseous reagents. As well, performance characteristics of membrane-based vaporizers relying on transport processes are improved.

摘要： Apparatus for salt separation (2) under supercritical water conditions, comprising a heat exchanger (4) and a fluidized bed reactor (6). The fluidized bed reactor comprising a supercritical water pressure containing wall (8) defining therein a fluidized bed chamber (10) connected to an inlet system (16) at one end thereof and an outlet system (18) configured to separate solids from supercritical fluid at another end thereof. The fluidized bed chamber receives a fluidized bed (12) therein and is configured to receive through the inlet system (16) a liquefied aqueous substance (14) for treatment in the fluidized bed chamber. The inlet system (16) comprises an inlet chamber (20) and a fluidization plate (22) positioned between the inlet chamber (20) and the fluidized bed chamber (10). The fluidized bed chamber extends between the inlet system (16) and outlet system (18) and comprises an entry section (10a) adjacent the inlet system (16), an outlet section (10c) adjacent the outlet system (18), and a mid-section (10b) extending between the entry section and the outlet section. The heat exchanger (4) extends along the fluidized bed chamber (10) and is configured to generate a decreasing temperature gradient in the fluidized bed chamber from the outlet section (10c) to the entry section (10a), the temperature gradient in the outlet section and mid-section being supercritical for aqueous substances and being subcritical for aqueous substances in the entry section (10a) adjacent the fluidization plate (22).

摘要： In an example implementation, a method of microfluidic filtering includes activating a first fluid pump within a microfluidic channel to cause a forward flow of fluid through the microfluidic channel and through a filter of a filter loop. The filter loop intersects the microfluidic channel at a loop entry and at a loop exit. The method includes activating a second fluid pump to cause a reverse flow of fluid through the filter.

摘要： A sight glass apparatus for viewing the interior of a pressurised vessel, chamber or a pipe conveying fluid under pressure is described. The sight glass apparatus comprises a sight glass assembly mounted over an opening into the vessel, chamber or pipe, the sight glass assembly comprising a sight glass adjacent the opening which provides a window to the inside of the vessel, chamber or pipe, and a containment vessel mounted behind and/or around the sight glass assembly for containing fluid exiting the opening in the pipe in the event that the sight glass assembly fails. In this way, even if the sight glass assembly fails, the pressurised fluid within the pressurised vessel, chamber or pipe is safely contained. In addition, a secondary sight glass can be provided behind the first, with a liquid or gel, or minimal gap, between the primary and secondary glasses to reduce the likelihood of a failure in the first sight glass triggering failure of the second sight glass, and/or a valve can be provided to automatically isolate the pressure system upon a sight glass failure.

摘要： Methods for creating nanostructured surface features on polymers and polymer composites involve application of low pressure during curing of solid polymer material from a solvent solution. The resulting nanoscale surface features significantly decrease bacterial growth on the surface. Polymer materials having the nanoscale structuring can be used in implantable medical devices to inhibit bacterial growth and infection.
