      abstract     = {Ultrasmall Au, Pd and AuPd nanoparticles (NPs) stabilized
                      by PVP were prepared in a microfluidic reactor with cyclone
                      micromixers for rapid mixing of reactants. In this system,
                      pulsation-free flow of reactants was achieved at a total
                      flow rate of 2.6 L h-1. A rapid homogeneous mixing within 2
                      ms was obtained with three cyclone micromixers. Controlled
                      NP nucleation and growth occur in a following meandering
                      microchannel. The resulting colloidal NPs were characterized
                      thoroughly by various complementary techniques e.g. high
                      resolution transmission electron microscopy (HRTEM),
                      energy-dispersive X-ray spectroscopy (EDX) and
                      Ultraviolet-visible spectroscopy. The average NP diameter
                      was about 1 nm with a narrow size distribution and electron
                      microscopy showed homogeneously alloyed NPs. Moreover, the
                      particles were supported on TiO2. for catalytic tests and
                      further structural characterization. Electron microscopy
                      showed a uniform distribution of NPs on the support with
                      some aggregation. X-ray absorption spectroscopy (XAS)
                      confirmed the formation of well-mixed AuPd alloys in NP
                      cores with Pd-rich surfaces. Finally, 1 $wt.\%$ metal loaded
                      supports showed catalytic activities in CO oxidation in the
                      following order: Au/TiO2. ≥ AuxPdy/TiO2. ≥ Pd/TiO2.
                      Hence, the physical and chemical properties of these
                      catalysts can be fine-tuned.},
