1. Internal oxidation processing : New alloys and new simulation techniques
Abstract : Nitriding and oxidising treatments of alloys for toolingpurposes have been investigated both experimentally andtheoretically. Specimens prepared by a combination of differentprocessing steps are investigated by light-optical, scanningand transmission electron microscopy and hardness measurments. READ MORE

2. Development of Methanol-Reforming Catalysts for Fuel Cell Vehicles
Abstract : Vehicles powered by proton exchange membrane (PEM) fuelcells are approaching commercialisation. Being inherently cleanand efficient sources of power, fuel cells constitute asustainable alternative to internal combustion engines to meetfuture low-emission legislation. READ MORE

3. A study on the Submerged Entry Nozzels (SEN) respecting clogging and decarburization
Abstract : The submerged entry nozzle (SEN) has been used to transport the molten steel from tundish to the mould. The main purpose of the SEN usage is both to prevent oxygen and nitrogen pick-up by molten steel and to achieve the desired flow condition in the mould. READ MORE

4. The Buried Oxide of Silicon on Insulator Materials
Abstract : The buried oxide of silicon on insulator (SOI) wafers plays an important role in the operation of electronic devices made on such materials. The presence of defects in the buried oxide can seriously degrade the performance of a circuit. READ MORE

5. An Experimental Study of Submerged Entry Nozzles (SEN) Focusing on Decarburization and Clogging
Abstract : The submerged entry nozzle (SEN) is used to transport the molten steel from a tundish to a mould. The main purpose of its usage is to prevent oxygen and nitrogen pick-up by molten steel from the gas. Furthermore, to achieve the desired flow conditions in the mould. READ MORE
