    • Æther as an Inevitable Consequence of Quantum Gravity 

      Cherkas, Sergey; Kalashnikov, Vladimir (Peer reviewed; Journal article, 2022)
      The fact that quantum gravity does not admit an invariant vacuum state has far-reaching consequences for all physics. It points out that space could not be empty, and we return to the notion of an æther. Such a concept ...

    • α-Mg primary phase formation and dendritic morphology transition in solidification of a Mg-Nd-Gd-Zn-Zr casting alloy 

      Casari, Daniele; Mirihanage, Wajira; Falch, Ken Vidar; Ringdalen, Inga Gudem; Friis, Jesper; Schmid-Fetzer, Rainer; Zhao, Dongdong; Li, Yanjun; Sillekens, Wim H.; Mathiesen, Ragnvald (Journal article; Peer reviewed, 2016)
      Microstructure evolution in the commercial Mg-Nd-Gd-Zn-Zr alloy Elektron 21, solidified under nearly isothermal conditions, has been studied via in-situ X-ray radiography. For cooling rates View the MathML source≤0.075 ...

    • β- and δ-Al-Fe-Si intermetallic phase, their intergrowth and polytype formation 

      Becker, Hanka; Bergh, Tina; Vullum, Per Erik; Leineweber, Andreas; Li, Yanjun (Journal article; Peer reviewed, 2019)
      Crystal structure characteristics of coexisting β and δ phase were investigated in a purely intermetallic Al-Fe-Si alloy and in plate-shaped intermetallic particles formed in a model secondary Al7.1Si1.2Fe0.3Mn alloy. The ...

    • β-(1 → 3)(1 → 6)glucan from Schizophyllum commune 227E.32: High yield production via glucose/xylose co-metabolization 

      Vanin, Ana Paula; Visentin, Esther Ziliotto; Fontana, Roselei Claudete; di Medeiros Leal, Maria Carolina Bezerra; de Avila e Silva, Scheila; Stokke, Bjørn Torger; Carbonero, Elaine Rosechrer; Camassola, Marli (Peer reviewed; Journal article, 2023)
      A co-metabolization of xylose and glucose by Schizophyllum commune 227E.32 wild mushroom for exopolysaccharide (EPS) production is presented. Cultivations performed with S. commune 227E.32 at different xylose concentrations ...
