  2. 16. Selective Comminution Applied to Mineral Processing of Critical Metals

    Author : Lorena Guldris Leon; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; selective comminution; compressive crushing; analytical method; minerals; critical metals; elements.;

    Abstract : The outstanding properties of tungsten and tantalum make them valuable metals and, in some cases, irreplaceable in applications. Due to the vital economic importance and limited supply, growing interest places these metals on the critical metals risk list. READ MORE

  4. 17. Mechanical Behavior of Tailings : Laboratory Tests from a Swedish Tailings Dam

    Author : Riaz Bhanbhro; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tailings dams; Tailings; Mechanical Behavior; Oedometer; Direct Shear; Triaxial; Shear strength; Soil Mechanics; Geoteknik;

    Abstract : Tailings is leftover material from mining industry and is produced in huge quantities approximately 70-99% of the ore production.  Tailings material is stored as impoundments by constructing tailings dams which are often constructed with tailings material itself. READ MORE

  5. 18. Melt Spun Electro-Conductive Polymer Composite Fibers

    Author : Azadeh Soroudi; Högskolan i Borås; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conductive fibres; composites; blending; melt spinning; morphology; polyaniline; carbon nanotube; polypropylene; polyamide; draw-ratio; conductivity; Energi och material;

    Abstract : One interesting approach is the development of conductive polymer composite fibers for innovative textile applications such as in sensors, actuators and electrostatic discharge. In this study, conductive polymer composite fibers were prepared using several different blends containing conductive components: a conjugated polymer (polyaniline-complex) and/or carbon nanotubes.

  6. 19. Characterization and densification of carbonized lignocellulosic biomass

    Author : Magnus Rudolfsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis focuses on developing two main areas: characterization and densification of carbonized lignocellulosic biomass. Thermally treated biomass undergoes changes that enrich the content of carbon in the remaining solid fraction. READ MORE

  7. 20. Breast Cancer Biomarkers with Clinical Relevance Identified by Massively-parallel DNA and RNA Sequencing

    Author : Malin Dahlgren; Translational Oncogenomics; []

    Abstract : Women have a 10% lifetime risk of developing breast cancer, and the disease has surpassed lung cancer as the most frequently diagnosed type of cancer in the world. Breast cancer originates in the epithelial cells of the mammary gland and tumor cells have undergone a series of genetic and phenotypic changes that confer tumor promoting properties. READ MORE
