Publication number: 20120028791Abstract: A method for manufacturing anatase TiO2 nanoparticles comprises mixing (210) of Ti-containing alkoxide precursors with a solvent into a precursor solution, hydrolyzing (212) the precursor solution to yield a mixture of a fine titanium containing precipitate and the solvent and hydrothermally treating (214) the precipitate at an elevated temperature in a basic medium. The basic medium is provided after the hydrolysis. The basic medium comprises basic amines. A highly active photocatalytic material is thus presented, comprising anatase TiO2 nanoparticles, which have a mean diameter of less than 100 nm and have at least one of a {111}, a {112}, and a {100} crystal face. The material can be tuned for selective carboxylate-surface coordination.Type: ApplicationFiled: March 24, 2010Publication date: February 2, 2012Inventors: Lars Österlund, Gunnar Westin, Michael Leideborg

Patent number: 8034152Abstract: A novel solution route has been developed that after heat-treatment to 500-600° C. under inert atmosphere, yields highly porous composites of nano-sized metal (Ni) particle inclusions in ceramics (Al2O3). Metal loadings could be made from <1% to >95% Ni. The metal inclusion sizes in the Ni—Al2O3 system with the 10 atom % Ni sample were 4-7 nm, while for the 75 atom % Ni sample they were 5-8 nm. It was shown that the 10 atom % Ni sample could be used as a catalyst for the conversion of CO2 and CH4 in the temperature range 550-700° C., while higher temperatures led to growth of the Ni particles and carbon poisoning over time. The solution routes could also be deposited as thin dense films containing <10 nm Ni particles. Such films with high Ni-particle loadings deposited on aluminium substrates have shown very good solar heat absorber proficiency and provide good substrates for carbon tube growth.Type: GrantFiled: May 21, 2010Date of Patent: October 11, 2011Inventors: Gunnar Westin, Annika Pohl, Asa Ekstrand

Patent number: 6033735Abstract: There is disclosed a method of coating cemented carbide inserts at least partly with a layer of at least one iron group metal. When inserts coated with such a layer are brazed to a tool holder, a joint with improved strength is obtained. According to the present method, one or more metal salts of at least one iron group metal containing organic groups are dissolved and complex bound in at least one polar solvent with at least one complex former comprising functional groups in the form of OH or NR.sub.3 (R.dbd.H or alkyl). A soluble carbon source is added to the solution which is subsequently at least partly applied to the cemented carbide inserts by dipping, spraying or painting. The inserts are dried and heat treated in an inert and/or reducing atmosphere. As a result, cemented carbide inserts are obtained at least partly coated with a layer of an iron group metal.Type: GrantFiled: September 18, 1997Date of Patent: March 7, 2000Assignee: Sandvik ABInventors: Stefan Ederyd, Enrico Galli, Mats Nygren, Gunnar Westin, Asa Ekstrand
