Abstract: A method is provided for placing high surface area catalyst material (320) within ceramic micro-reactors. The method comprises forming a first cavity (114) in a first green sheet (112) and disposing a high surface area catalyst material (320) within the first cavity (114). The first green sheet (112) is placed adjacent to a second green sheet 118 wherein the first cavity is surrounded by the first and second green sheets. At least one input channel (316) and one output channel (317) is provided to the catalyst material before the ceramic micro-reactor is fired.

Abstract: An apparatus is provided for measuring the amount of fluid (21) flowing in a channel (18, 20). The apparatus comprises a fluidic oscillation flow meter (10) including a housing (14) defining an inlet (16) for receiving the fluid (21), and first and second diversion channels (18, 20) for alternately receiving the fluid (21) from the inlet (16). The housing (14) comprises a first nozzle (46) for receiving the fluid (21) from the first diversion channel (18) and deflecting the fluid (21) from the inlet (16) into the second diversion channel (20). A second nozzle (48) receives the fluid (21) from the second diversion channel (20) and alternately deflects the fluid (21) from the inlet (16) into the first diversion channel (18). A first layer of material (56) overlies at least one of the first and second diversion channels (18, 20) and includes a sensing area that distorts due to a pressure change caused by the fluid (21) flowing through the diversion channels (18, 20).

Abstract: An exemplary system and method for providing substantially uniform mixing of fluid reactants, wherein the flow velocities and/or device dimensions generally correspond to Reynolds numbers less than unity, is disclosed as comprising inter alia: a first fluid inlet (210); a second fluid inlet (220); and a fluid transport channel (240) having a plurality of features (250) corresponding to relatively discontinuous or otherwise abrupt shifts in the fluid transportation gradient. Disclosed features and specifications may be variously controlled, adapted or otherwise optionally modified to improve mixing operation in any diffusion limited application. Exemplary embodiments of the present invention representatively provide for efficient mixing of fluid phases at relatively low Reynolds numbers and may be readily integrated with existing micro-scale technologies for the improvement of device package form factors, weights and other manufacturing and/or device performance metrics.
