1. 1. Characterization of flow regimes between supercritical carbon dioxide and water in microfluidics, comparing coated and mechanically modified channels.

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Mikrosystemteknik

   Författare :Niklas Rogeman; [2014]
   Nyckelord :;

   Sammanfattning : Water and supercritical carbon dioxide have different wetting angles to a glass surface, where water has a lower angle. In a microfluidic channel, the lower wetting angle draws the water to surround the supercritical carbon dioxide and the supercritical carbon dioxide therefore easily form droplets or segments if the flow rate is low.

3. 2. Rostfritt stål till stora vattentankar utomhus : En jämförelse mellan austenitiska och rostfria stål

   Kandidat-uppsats, Tillämpad materialvetenskap

   Författare :Erika Edling; Malin Börjesson; Niklas Rogeman; Sarmad Naim Katea; Jenny Bengtsson; Johan Söderberg Breivik; Markus Wessman; [2012]
   Nyckelord :austenitic stainless steels; duplex stainless steels; austenitiska rostfria stål; duplexa rostfria stål;

   Sammanfattning : The austenitic stainless steel 316L has been compared to duplex stainless steels to be able to highlight a choice of material for manufacturing of spare tanks used for cooling water at nuclear power stations on the Swedish west coast. In this report 316L and the duplex stainless steels 2205, 2304 and LDX 2404 have been compared according to corrosion resistance, strength, manufacturing aspects and prices. LÄS MER
