  2. 1. Development of Nanostructured Tungsten Based Composites for Energy Applications

    Author : Mazher Ahmed Yar; Mamoun Muhammed; Per-Olov Käll; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tungsten; Nano-tungsten; ODS tungsten; W-La2O3; W-Y2O3; SPS; Plasma-facing materials; Armour material; fusion material;

    Abstract : Tungsten (W) based materials can be used in fusion reactors due to several advantages. Different fabrication routes can be applied to develop tungsten materials with intended microstructure and properties for specific application including nanostructured grades. READ MORE

  4. 2. Material Hygiene : An EcoDesign mindset for recycling of products

    Author : Jan Johansson; Conrad Luttropp; Stephen Evans; KTH; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In recent years the end-of-life phase has come into focus. European Union directives have been issued regulating certain product groups and producer responsibility. Vehicles and electronic products are the first to be identified and targeted. EU environmental legislation acts as a driver for increased reuse, recycling and recovery. READ MORE

  5. 3. Shear Fracture and Delamination in Packaging Materials : A study of Experimental Methods and Simulation Techniques

    Author : Md. Shafiqul Islam; Sharon Kao-Walter; Christian Johansson; Johan Tryding; Blekinge Institute of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Package opening; Shear test specimen; Stress intensity factor; Finite Element simulation; Scanning electron microscopy; Polymers; Interlaminar shear delamination;

    Abstract : Packages are the means of preservation, distribution and convenience of use for food, medicine and other consumer products. Package opening is becoming complicated in many cases because of cutting cost in design and production of opening techniques. READ MORE

  6. 4. Nanostructured Bulk Thermoelectrics : Scalable Fabrication Routes, Processing and Evaluation

    Author : Mohsen Yakhshi Tafti; Muhammet S. Toprak; Gao Min; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermoelectric; Iron antimonide FeSb2 Skutterudite; Copper Selenide Cu2Se ; Spark Plasma Sintering SPS ; nanomaterial; Teknisk materialvetenskap; Materials Science and Engineering; Energy Technology; Energiteknik;

    Abstract : Current fossil fuel based energy sources have a huge shortcoming when one discusses their efficiency. The conversion efficiency of fossil fuel-based technologies is less than 40% in best cases. READ MORE

  7. 5. Sublimation Growth of 3C-SiC : From Thick Layers to Bulk Material

    Author : Valdas Jokubavičius; Mikael Syväjärvi; Rositsa Yakimova; Didier Chaussende; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Silicon carbide (SiC) is a semiconductor material which holds high promises for various device applications. It can be obtained in different crystal structures called polytypes. The most common ones are hexagonal (6H- and 4H-SiC) and cubic (3C-SiC) silicon carbide. READ MORE
