  • Patent number: 9109121
    Abstract: Methods and compositions for forming porous low refractive index coatings on substrates are provided. The method comprises coating a substrate with a sol-formulation comprising silica based nanoparticles and an alkyltrialkoxysilane based binder. Use of the alkyltrialkoxysilane based binder results in a porous low refractive index coating having bimodal pore distribution including mesopores formed from particle packing and micropores formed from the burning off of organics including the alkyl chain covalently bonded to the silicon. The mass ratio of binder to particles may vary from 0.1 to 20. Porous coatings formed according to the embodiments described herein demonstrate good optical properties (e.g. a low refractive index) while maintaining good mechanical durability due to the presence of a high amount of binder and a close pore structure.

  • Publication number: 20150208695
    Abstract: This invention describes a collagen fiber reconstituted rawhide useful in the production of pet chews, and a method for making the same. Beginning materials include animal skins with hair, depilated limed splits and leftovers from the manufacture of rawhide pet chews. The materials are pretreated, ground, subjected to acid treatment to swell and separate the collagen fibers that comprise the animal hide, further ground into pulp, vacuum filtered, mixed with a dehydration agent that chemically shrinks the expanded fibers, drained, formed and dried into sheet and/or exposed to a cross-linking agent to increase the adhesive strength of the end product. Edible materials, including meats, may be added to the solution prior to draining, to enhance the nutritional value and palatability of the final product, and the reconstituted rawhide sheets may be bleached for appearance.

  • Patent number: 9052456
    Abstract: A bi-layer seed layer can exhibit good seed property for an infrared reflective layer, together with improved thermal stability. The bi-layer seed layer can include a thin zinc oxide layer having a desired crystallographic orientation for a silver infrared reflective layer disposed on a bottom layer having a desired thermal stability.

  • Patent number: 8906709
    Abstract: Provided are methods of high productivity combinatorial (HPC) inspection of semiconductor substrates. A substrate includes two layers of dissimilar materials interfacing each other, such as a stack of a silicon bottom layer and an indium gallium arsenide top layer. The dissimilar materials have one or more of thermal, structural, and lattice mismatches. As a part of the inspection, the top layer is etched in a combinatorial manner. Specifically, the top layer is divided into multiple different site-isolated regions. One such region may be etched using different process conditions from another region. Specifically, etching temperature, etching duration and/or etchant composition may vary among the site-isolated regions. After combinatorial etching, each region is inspected to determine its etch-pit density (EPD) value. These values may be then analyzed to determine an overall EPD value for the substrate, which may involve discarding EPD values for over-etched and under-etched regions.

  • Patent number: 8865518
    Abstract: Resistive switching memory elements are provided that may contain electroless metal electrodes and metal oxides formed from electroless metal. The resistive switching memory elements may exhibit bistability and may be used in high-density multi-layer memory integrated circuits. Electroless conductive materials such as nickel-based materials may be selectively deposited on a conductor on a silicon wafer or other suitable substrate. The electroless conductive materials can be oxidized to form a metal oxide for a resistive switching memory element. Multiple layers of conductive materials can be deposited each of which has a different oxidation rate. The differential oxidization rates of the conductive layers can be exploited to ensure that metal oxide layers of desired thicknesses are formed during fabrication.
