2. 1. CVD on Iron Powder - Using Fluidising Bed Techniques

   Author : Lars Nilsson; Industriell Produktion; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminium oxide; alumina; chemical vapour deposition; eddy current losses; FBR; iron; fluidising bed reactor; powder; SiO2; SMC; TiO2; Al2O3; soft ma etic com sites; CVD;

   Abstract : Today's electrical energy conversion devices, such as motors, transformers, inductors and generators, are based on laminated magnetic cores for reduction of eddy current losses, imposing a two-dimensional magnetic flux distribution. Using a three-dimensional magnetic flux distribution while maintaining low magnetic losses requires new approaches to magnetic core materials. READ MORE

4. 2. Development of Encapsulated UN-UO₂ Accident Tolerant Fuel

   Author : Diogo Ribeiro Costa; Pär Olsson; Janne Wallenius; Simon Middleburgh; Magnus Limbäck; Denise Adorno Lopes; Ho Jin Ryu; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Accident tolerant fuel; UN-UO2 composite fuel; coating technology; powder coating; chemical vapour deposition CVD ; physical vapour deposition PVD ; UN spheres; spark plasma sintering; Kärnenergiteknik; Nuclear Engineering;

   Abstract : Accident tolerant fuels (ATFs) are designed to endure a severe accident in the reactor core longer than the standard UO2-Zr alloy systems used in light water reactors (LWRs). Composite fuels such as UN-UO2 are being considered as an ATF concept to address the lower oxidation resistance of the UN fuel from a safety perspective for use in LWRs, whilst improving the in-reactor behaviour of the UO2 fuel.

5. 3. Processing of berries – Effects on functionality, stability and bioactivity of anthocyanins

   Author : Gabriel Barbosa; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; berries; powder; hot air and microwave drying; osmotic dehydration; press cake; edible coating; anthocyanins; gastrointestinal in vitro digestion; polyphenols; pulsed electric field; oxidative stress; yeast;

   Abstract : Berries are rich natural sources of anthocyanins, water-soluble pigments in plants that have been linked to beneficial effects against chronic diseases, such as cardiovascular diseases, type 2 diabetes and neurodegenerative diseases. However, anthocyanins as well as other polyphenolic compounds are often sensitive to degradation during processing, storage and digestion. READ MORE

6. 4. Novel powder-coating solutions to improved micro-structures of ZnO based varistors, WC-Co cutting tools, and Co/Ni nano-phase films and sponges

   Author : Åsa Ekstrand; Mari-Ann Einarsrud; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Solution processing; powder coating; nano-phase materials; sintering process; varistor; WC–Co; cobalt; nickel; films; sponges; Kemi; Chemistry; Kemi; Inorganic Chemistry; Oorganisk kemi;

   Abstract : Solution chemistry is a versatile and powerful tool in the synthesis of designed, complex nano-level high-tech materials. Normally, the technique is considered too expensive for large-scale production of complex multi-component ceramic materials. READ MORE

7. 5. An Experimental Study of Submerged Entry Nozzles (SEN) Focusing on Decarburization and Clogging

   Author : Arashk Memarpour; Pär Jönsson; Torbjörn Carlberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refractory; SEN; Clogging; REM; Coating; glaze; alkaline; Post- Mortem; industrial preheating; ZrSi2; Graphite; Alumina; Oxidation; Al2O3-C; ZrO2-C; MgO-C; decarburization; reaction mechanism; Yttria Stabilized Zirconia; plasma spray-PVD coating;

   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
