20110257277 | POLYTHIOPHENE COMPOSITIONS FOR IMPROVING ORGANIC LIGHT-EMITTING DIODE - The invention relates to compositions which include: (a) a polythiophene containing repeating units represented by the following general formula (I), | 10-20-2011 |
20100015467 | METHOD FOR COATING A SUBSTRATE AND COATED PRODUCT - Disclosed is a method of applying coatings to surfaces, wherein a gas flow forms a gas-powder mixture with a powder of a material selected from the group consisting of niobium, tantalum, tungsten, molybdenum, titanium, zirconium, nickel, cobalt, iron, chromium, aluminum, silver, copper, mixtures of at least two thereof or their alloys with at least two thereof or with other metals, the powder has a particle size of from 0.5 to 150 μm, an oxygen content of less than 500 ppm oxygen and a hydrogen content of less than 500 ppm, wherein a supersonic speed is imparted to the gas flow and the jet of supersonic speed is directed onto the surface of an object. The coatings prepared are used, for example, as corrosion protection coatings. | 01-21-2010 |
20090214378 | METHOD FOR THE PRODUCTION OF VALVE METAL POWDERS - The present invention relates to a process for the deoxidation of valve metal primary powders by means of reducing metals and/or metal hydrides, and a process for the production of tantalum powders that are suitable as anode material for electrolytic capacitors. | 08-27-2009 |
20090018010 | Metal Borides - The invention is related to a boride of a metal of transition group four of the periodic table of the elements, wherein at least 40 wt. % of the particles have a grain size of more than 106 μm, determined by sieve analysis according to ASTM B 214, and these particles consist of grown, monocrystalline grains. The invention also relates to a cermet, wettable powder and a surface coating which contain the boride. The invention further relates to a process to prepare the boride. The invention additionally relates to a process to prepare a cermet or a wettable powder. | 01-15-2009 |
