  1. 21. Electrolytic Extraction of Aluminium Bifilms

    University essay from KTH/Materialvetenskap

    Author : Simon Bergfors; Davida Flink; [2020]
    Keywords : Aluminium; Bifilms; Oxide films; Electrolytic extraction; Scanning electron microscope; Aluminium; Oxidfilm; Elektrolytisk extraktion; Svepelektronmikroskop;

    Abstract : Bifilms is the oxide layer created between two surfaces in the melt of light metals that form an oxide layer. These become planar inclusions in the final casting and are problematic for the mechanical properties such as cracks and crack initiations. READ MORE

    Author : Marius de Mourgues; [2020]
    Keywords : ;

    Abstract : Biodegradable polymers are emerging as a new solution to satisfy the increasing demand of greenenvironmentally friendly material. At the same time, the interest for lighter and stronger structures never stops growing. READ MORE

  4. 23. Lateral variability in the quantification of calcareous nannofossils in the Upper Triassic, Austria

    University essay from Lunds universitet/Geologiska institutionen

    Author : Andreas Fägersten; [2018]
    Keywords : Calcareous nannofossils; Upper Triassic; Steinbergkogel; lateral variability; limestone; Earth and Environmental Sciences;

    Abstract : Calcareous nannofossils are microscopic remains of organisms that diversified considerably in and after the Late Triassic, and which may have influenced seawater chemistry and carbonate production. Coccoliths, nannoliths, and calcareous dinoflagellate cysts are important parts of many calcareous nannofossil assemblages in the Upper Triassic. READ MORE
