    Abstract : The potential for recycling various polymeric materials contained within buildings constructed in the late 1960s and 1970s in Sweden was investigated during the course of this work. Three residential blocks were studied to establish the quantity of materials available for recycling, to investigate the difficulty in and time needed for the dismantling of the buildings, the degree of purity of the materials, and the possibility of separating the materials.

  2. 2. Annealing of Cu2ZnSn(S,Se)4 Thin Films : A Study of Secondary Compounds and Their Effects on Solar Cells

    Author : Yi Ren; Charlotte Platzer-Björkman; Maarja Grossberg; Uppsala universitet; []
    Keywords : Annealing; sputtering; thin film; CZTS; secondary phases; solar cell; Engineering Science; Teknisk fysik;

    Abstract : Kesterite Cu2ZnSnS4 (CZTS) is interesting as a sustainable photovoltaic technology due to its earth-abundant elements and suitable semiconducting properties. To date, a record efficiency of 12.6% has been achieved but further improvements are required to reach high efficiency for industrial implementation. READ MORE

  5. 5. Fundamentals of substructure dynamics : In-situ experiments and numerical simulation

    Author : Verity Borthwick; Sandra Piazolo; Dorte Juul Jensen; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; halite; in-situ; X-ray diffraction; EBSD; annealing; substructure; modelling; Earth sciences; Geovetenskap; Geology; geologi;

    Abstract : Substructure dynamics incorporate all features occurring on a subgrain-scale. The substructure governs the rheology of a rock, which in turn determines how it will respond to different processes during tectonic changes. READ MORE
