摘要： 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.

摘要： A class of crystals comprises an inorganic lattice in which organic molecules are embedded, thereby allowing macroscopic electro-optic responsiveness. The lattice is based on a metal halide perovskite structure. The organic molecules can be with an intrinsic dipole such that when aligned and fixed in place in the inorganic lattice, they induce electro-optic responsiveness in the macroscopic crystal. Alternatively, their mere presence in the structure can induce sufficient polarity in the scaffold itself for a similar responsiveness. The molecules themselves can comprise a carbon backbone that is completely conductive, partially conductive, or non-conductive, as well as zero, one or two functional groups that allow binding to the lattice and increased polarity.
