1. 1. Treatment of organic pollutants in high salinity wastewater : new catalysis systems

   Författare :Han Yu; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High salinity wastewater; Electrochemical catalysis; Photo-electro catalysis; Degradation;

   Sammanfattning : High salinity wastewater (HSW, NaCl mass fraction ≥ 1%) from industries and aquacultures contains massive organic matters with a wide variety. These organic matters have been considered as significant threaten to both human and environment. The removal and degradation of them before discharge emerge as necessity. LÄS MER

4. 3. Anisotropic mechanical behaviors and microstructural evolution of thin-walled additively manufactured metals

   Författare :Cheng-Han Yu; Johan Moverare; Ru Lin Peng; Joe Kelleher; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hot tensile testing; slow strain rate tensile testing; creep; anisotropy; crystallographic texture evolution; deformation twinning; Varmdragprov; Dragprov med låg töjningshastighet; kryp; anisotropi; kristallografisk textur; deformationstvillingar;

   Sammanfattning : Additive manufacturing (AM), also known as 3D printing, is a concept and method of a manufacturing process that builds a three-dimensional object layer-by-layer. Opposite to the conventional subtractive manufacturing, it conquers various limitations on component design freedom and raises interest in various fields, including aerospace, automotive and medical applications.
