Abstract: The present disclosure provides substantially homogeneously dispersed multimetal oxy-hydroxide catalyst comprising at least two metals, at least one metal being a transition metal, and at least a second metal which is structurally dissimilar to at least one metal, such that the multimetal oxy-hydroxide is characterized by being substantially homogeneously dispersed and generally not crystalline. A key feature of the present materials is that the presence of the structurally dissimilar metal results in sufficient strain produced in the final multimetal oxy-hydroxide material to prevent crystallization from occurring. The resulting materials are specifically not annealed at temperatures that would induce crystallization in order to avoid the expected phase segregation that would occur during crystallization.

Abstract: Methods and devices for magnetic profiling of target particles in a flow. There are a plurality of flow rate-reducing structures in a flow chamber. Each flow rate-reducing structure is provided with a localized magnetic attractive force, the magnetic attractive force defining a capture zone in the vicinity of the flow rate-reducing structure. The size of capture zones may be variable for different locations within the device. The magnetic attractive force, in the capture zone, is sufficiently high to overcome the drag force on a given subset of the target particles to promote capture of any particles belonging to the subset of the target particles in the capture zone. Different target particles having different magnetic susceptibility are captured in different capture zones.
