  2. 1. Experimental and computational investigation of the roll forming process

    Author : Michael Lindgren; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rollforming; Roll Forming; Flexible roll forming; Rullformning; Simulering och experimentell undersökning av rullformningsprocessen;

    Abstract : One of the first questions to consider when designing a new roll forming line is the number of forming steps required to produce a profile. The number depends on material properties, the cross-section geometry and tolerance requirements, but the tool designer also wants to minimize the number of forming steps in order to reduce the investment costs for the customer.

  4. 2. Mechanical modelling of blade forming and drainage of flocculated suspensions

    Author : Claes Holmqvist; Anders Dahlkild; Douglas Bousfield; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; blade forming; pressure distribution; interaction; suction; drainage; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Abstract : A method has been developed for flexible modelling of multi-component twin-wire blade formers. Features such as suction devices, loadable blades, curved blades, and partial contact between the blades and the forming fabrics are easily incorporated. READ MORE

  5. 3. Light-Emitting Electrochemical Transistors

    Author : Jiang Liu; Magnus Berggren; Isak Engquist; Qibing Pei; Linköpings universitet; []
    Keywords : ;

    Abstract : Since the discovery of conductive polymers in 1977, the implementation of organic conjugated materials in electronic applications has been of great interest in both industry and academia. The goal of organic electronics is to realize large-area, inexpensive and mechanically-flexible electronic applications. READ MORE

  6. 4. Semiconductor Nanowires: Characterization and surface modification

    Author : Sofie Yngman; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; semiconducting nanowire; atomic force microscopy; Scanning tunneling microscopy; X-ray Photoelectron Spectroscopy; Scanning Probe Microscopy; Nanowires; Sveptunnelmikroskopi; Atomkraftsmikroskopi; XPS; Halvledarfysik; nanotrådar;

    Abstract : The topic of III-V nanowires is still, after more than two decades, a growing and lively research area. The areas of application are wide and contain such important topics as energy harvesting, cheap and efficient lighting, high efficiency detectors and new types of electronics. III-V materials offer properties superior to the widely used Si. READ MORE
