  • Patent number: 11952480
    Abstract: In some embodiments, the present disclosure provides a composition comprising 1) about 97.5 wt % to about 99.9 wt % of a first polyethylene having a density of about 0.91 g/cm3 to about 0.94 g/cm3, and a melt strength of about 10 mN or greater; and 2) about 0.1 wt % to about 2.5 wt % of a second polyethylene having an Mw of about 500,000 g/mol or more. In some embodiments, the composition is a film. In some embodiments, the present disclosure provides a method of making a composition comprising blending a first polyethylene of any embodiment described herein and a second polyethylene of any embodiment described herein.

  • Publication number: 20230366809
    Abstract: A method for determining at least one property of magnetic matter includes: applying a magnetic field to magnetic matter; directing first light on the magnetic matter at a first set of incident angles; receiving a first set of signatures associated with the first light scattered from the magnetic matter; varying orientation of the magnetic matter with respect to the magnetic field; directing second light on the magnetic matter at a second set of incident angles; receiving a second set of signatures associated with the second light scattered from the magnetic matter; determining, by processing the first set and the second set of signatures according to a dispersion relation, at least one property of the magnetic matter.

  • Publication number: 20140209683
    Abstract: A method and apparatus for identifying an object having a pattern of plasmon resonant particles (PREs) distributed in or on the object are disclosed. In the method, a field containing the pattern is illuminated, and one or more spectral emission characteristics of the light-scattering particles in the field are detected. From this data, an image of positions and spectral characteristic values in the field is constructed, allowing PREs with a selected spectral signature to be discriminated from other light-scattering entities, to provide information about the field. The image may be compared to a database of reference images to identify or validate the object.

  • Patent number: 8309370
    Abstract: A method and apparatus for interrogating a target having a plurality of plasmon resonant particles (PREs) distributed in the target are disclosed. In the method, a field containing the target is illuminated, and one or more spectral emission characteristics of the light-scattering particles in the field are detected. From this data, an image of positions and spectral characteristic values in the field is constructed, allowing PREs with a selected spectral signature to be discriminated from other light-scattering entities, to provide information about the field. Also disclosed are a novel PRE composition for use in practicing the method, and a variety of diagnostic applications of the method.
