    摘要: The optical assemblies disclosed herein advantageously utilize a beamsplitting apparatus in association with either (i) the illumination path or (ii) the collection path of a color measurement instrument. For implementations involving the illumination path, the beamsplitting apparatus may be configured to spectrally divide one or more initial beams of light so as to emit a plurality of resultant beams of light, wherein the optical assembly is configured to illuminate a target using at least a first and a second of the plurality of resultant beams of light. Similarly, for implementations involving the collection path, the beamsplitting apparatus may be configured to spectrally divide light received from a target so as to emit a plurality of resultant beams of light, wherein the optical assembly is configured to detect at least a first and a second of the plurality of resultant beams of light. Advantageously, each of the first and second resultant beams of light is a product of a distinct set of one or more spectral constraints exacted by the beamsplitting apparatus.

    摘要: A catalyst composition for the polymerization of olefins is provided. The catalyst composition comprises a mono- or biscycloalkadienyl catalyst precursor comprising at least one protected hydride ligand or protected hydrocarbyl ligand bound to a metal atom plus a cocatalyst. The protected hydride ligand is preferably a borohydride ligand.

    摘要: A solar energy absorber is provided in which the absorber surface is comprised of a multiplicity of free ends of carbon or metallic fibers. The fibers forming the absorber surface are straight and are aligned in a parallel and side-by-side relationship. The small diameters of the fibers and the very close spacing of adjacent fibers of from 1 to about 10 micrometers provides a trap for solar energy. A solar energy absorbing device is also provided.
