  • Methods for conversion of lignocellulosic-derived products to transportation fuel precursors
    Patent number: 9777224
    Abstract: Methods are disclosed for converting a biomass-derived product containing levulinic acid and/or gamma-valerolactone to a transportation fuel precursor product containing diesel like hydrocarbons. These methods are expected to produce fuel products at a reduced cost relative to conventional approaches.

  • Organic-inorganic complexes containing a luminescent rare earth-metal nanocluster and an antenna ligand, luminescent articles, and methods of making luminescent compositions
    Patent number: 9017573
    Abstract: Luminescent compositions are described comprising lanthanide-containing nanoclusters comprising lanthanide atoms bonded to at least one semimetal or transition metal via an oxygen or sulfur atom. Novel compositions include an antenna ligand complexed with the nanoclusters. The rare earth-metal nanoclusters are in the size range of 1 to 100 nm. Articles, such as solar cells, are described in which the nanoclusters (with or without antenna ligands) are dispersed in a polymer matrix. Novel methods of making luminescent films are also described.

  • INTERNAL OPTICAL EXTRACTION LAYER FOR OLED DEVICES
    Publication number: 20140042422
    Abstract: A light-emitting device, which improves the light output of organic light emitting diodes (OLEDs), includes at least one porous metal or metalloid oxide light extraction layer positioned between the substrate and the transparent conducting material layer in the OLED. The index of refraction of the light extraction layer and the light scattering may be tuned by changing the pore size, pore density, doping the metal oxide, adding an insulating, conducting or semiconducting component, or filling the pores, for example. A method for forming the light-emitting device includes forming at least one light extraction layer comprising a porous metal or metalloid oxide on a substrate, for example, using atmospheric pressure chemical vapor deposition (APCVD), and subsequently, forming a transparent conducting material on the light extraction layer.
