    摘要: The invention provides devices and methods for increasing the degree of mixing of fluids, including under conditions of laminar flow and turbulent flow. In one embodiment, mixing of fluids using the invention's devices and methods is increased by splitting the flow of at least one of the fluids into two or more inlet channels. This is optionally followed by further splitting and merging (e.g., using one or more split and merge (SAM) mixer) the fluids.

    摘要: A supported catalyst is prepared by a process that includes establishing shell-removal conditions for a supported catalyst intermediate that includes capped nanoparticles of a catalyst material dispersed on a carbon support. The capped nanoparticles each include a platinum alloy core capped in an organic shell. The shell-removal conditions include an elevated temperature and an inert gas atmosphere that is substantially free of oxygen. The organic shell is removed from the platinum alloy core under the shell-removal conditions to limit thermal decomposition of the carbon support and thereby limit agglomeration of the catalyst material such that the supported catalyst includes an electrochemical surface area of at least 30 m2/gPt.
