20110010826 | SORPTION FILTER MATERIAL AND USE THEREOF - The invention relates to a sorption filter material, in particular an adsorption filter material, which is suitable in particular for producing protective materials of all types (such as protective suits, protective gloves, protective shoes and other protective clothing as well as protective coverings, e.g. for transporting patients, for sleeping bags or similar) and for producing filters and filter materials. Said material is suitable for both military and civilian use, in particular for ABC applications. | 01-20-2011 |
20110244130 | Method for Producing Photocatalytically Active Titanium Dioxide Layers - A method for manufacturing photocatalytically active titanium dioxide layers on substrate surfaces. The method reduces the effort for the manufacture of photocatalytically active titanium dioxide layers and increases the choice for the coating of suitable substrate materials. In the method, a titanium compound present in the gas phase and water vapor are directed to a preheated substrate by means of gas phase hydrolysis and a titanium dioxide layer is formed on the surface of the substrate by chemical reaction. In this respect, the titanium compound and water vapor are supplied separately from one another so that a flow speed of at least 0.5 m/s is achieved and the time between the first contact of the two gases up to the impact on the surface of the substrate is kept lower than 0.05 s, and in this process the photocatalytically active titanium dioxide layer is formed on the substrate surface. | 10-06-2011 |
20120168628 | METHOD AND DEVICE FOR DETERMINING THE ADSORPTION OF A GAS ON MATERIALS - The invention relates to a method and to an apparatus for determining the adsorption of a gas at materials. It is the object of the invention to propose possibilities for the determining of the surface properties of materials in which statements can be obtained and very small sample volumes can be examined with sufficient measurement precision, with a reduced technical plant effort and with a reduced time effort. In the invention, a sample of a material is acted on by a gas or gas mixture within a chamber which is not transparent for electromagnetic radiation in the wavelength range between 150 nm and 25 μm. The gas or at least a gas included in a gas mixture is adsorbed at the surface of the sample and in this respect the electromagnetic radiation emitted by the sample as a consequence of the adsorption is detected by at least one optical detector which is sensitive at least in a range of the wavelength range between 150 nm and 25 μm. The measured signals of the detector (s) are in this respect detected with time resolution and are evaluated within a predefinable time interval for determining the surface temperature and/or the adsorption heat of the respective sample varying due to the adsorption. | 07-05-2012 |
20120178262 | Process for the manufacture of wafers for solar cells at ambient pressure - Solar cells are manufactured from P-type doped monocrystalline or polycrystalline silicon ingots by sawing wafers and applying an N-type doping. The wafers can be treated by etching them, in a plasma assisted process, with an etching gas containing or consisting of carbonyl fluoride. Hereby, the surface is roughened so that the degree of light reflection is reduced, or glass-like phosphorus-containing oxide coatings caused by phosphorus doping are removed. Carbonyl fluoride is also very suitable to selectively etch silicon oxide in silicon oxide/silicon composites. | 07-12-2012 |
