  • Patent number: 9695111
    Abstract: Proposed is a method of producing soluble silicates with organic cations at a given silicate modulus in the range of 1.5 to 20. The method consists of the reacting liquid suspension of a silica sol with the aqueous solution of a strong organic base. The silicate modulus is a molar ratio of SiO2:M2O, wherein M is an organic alkali cation. The aqueous solution of a strong organic base has a constant of base dissociation pKb equal to or greater than 4. If necessary, the soluble silicates with organic cations are obtained in a powdered form by evaporating the solution of the soluble silicates under vacuum below 4.2 kPa and at a temperature in the range of 20 to 30° C. and the product of evaporation are then dried by spraying.

  • Patent number: 9035082
    Abstract: Substrates, surfaces, assemblies, kits, compositions, and methods are provided for forming touch screens and other appliance surfaces exhibiting good hydrophobicity, oleophobicity, and abrasion resistance. Methods are provided for increasing a population density of hydroxyl groups on a touch surface of a touch screen substrate without affecting the compressive strength of the back surface. The treated touch surface of the substrate can then be coated with a coating that includes an organo-metallic and/or silane, for example, a fluorosilane such as a perfluoropolyether alkoxysilane. A substrate can retain its compressive resistance to breakage by impact applied to the touch surface while minimizing any decrease in compressive strength against impact against the touch surface. Examples of such substrates include touch screens for mobile and desktop electronic devices, components of 3D display devices, and components for electrowetting display devices.

The mass ration of Zn(II)-curcumin complex and polyvinylpyrrolidone (PVP) K30 was 1:1˜1:28. The Zn(II)-curcumin complex was synthesized by mixing equimolar amounts of zinc acetate and curcumin in dry ethanol and refluxing the mixture under a nitrogen atmosphere. The Zn(II)-curcumin complex precipitated, and the solid was separated by filtration and washed several times by water and ethanol to remove any unreacted curcumin and zinc acetate. Zn(II)-curcumin and PVP-k30 were added to absolute ethanol to produce a suspension by cryo-grinding under a nitrogen atmosphere. SDs of Zn(II)-curcumin/PVP were produced with a spray dryer. Zn(II)-curcumin SDs showed predominant effects in curing various senile diseases by tackling disadvantages of curcumin and surmounted the problems of monoindication and unideal therapeutic efficacy general existed in drugs for senile disease treatment.

  • Publication number: 20120309999
    Abstract: A method of removing at least a portion of a silicon oxide material is disclosed. The silicon oxide is removed by exposing a semiconductor structure comprising a substrate and the silicon oxide to an ammonium fluoride chemical treatment and a subsequent plasma treatment, both of which may be effected in the same vacuum chamber of a processing apparatus. The ammonium fluoride chemical treatment converts the silicon oxide to a solid reaction product in a self-limiting reaction, the solid reaction product then being volatilized by the plasma treatment. The plasma treatment includes a plasma having an ion bombardment energy of less than or equal to approximately 20 eV. An ammonium fluoride chemical treatment including an alkylated ammonia derivative and hydrogen fluoride is also disclosed.
