A droplet-based microfluidic reaction scheme is developed where the chemical reactants are dispensed with precise volume control into pairs of droplets. The reaction is activated by coalescing droplet pairs and fast mixing inside the coalesced droplets. Furthermore, the pre-processing of the chemical products is included in the microfluidic device.

We describe here the use of liquid-feed flame spray pyrolysis (LF-FSP) to produce high surface area, nonporous, mixed-metal oxide nanopowders that were subsequently subjected to high-throughput screening to assess a set of materials for deNO(x) catalysis and hydrocarbon combustion. We were able to easily screen some 40 LF-FSP produced materials. LF-FSP(More)
Liquid flow in microfluidic channels typically occurs at low Reynolds numbers, such that the flow is purely laminar [Solomon et al. 2003; Oddy et al. 2001]. As a consequence, two or more streams of miscible fluids flowing side-by-side only mix by diffusion. Such a mixing is very slow and it would be difficult to perform chemical reactions within the typical(More)
