  1. 16. Microengineering of diamond

    Författare :Henrik Björkman; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Sammanfattning : Performance of micromechanical systems often relies on extreme material properties. Being the strongest, stiffest and hardest of all materials, exhibiting extreme electromagnetic transparency and wear resistance, and offering the highest possible thermal conductivity and very low friction against most materials, diamond is indeed a unique material.

  3. 17. Computational study of Polymerization, Crystallization and Mechanical Properties of Conducting Polymers

    Författare :Donghyun Kim; Igor Zozoulenko; Xavier Crispin; Mathieu Linares; Yun Hee Jang; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nowadays, electronic devices that include conducting polymers, ranging from batteries and OLED panel for TVs and smartphones to bioelectronics devices such as sensors and ion-pumps for drug-delivery are widely used in our life. The use of conducting polymer in many electronic applications was driven by demand for light weight, flexibility or biocompatibility with the performance on pair with conventional inorganic counterparts.

  5. 19. Material recycling of post-consumer flexible polyethylene packaging waste

    Författare :Ezgi Ceren Boz Noyan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; degradation; polyethylene; melt-compounding; washing; post-consumer flexible packaging waste; mechanical properties; plastics recycling;

    Sammanfattning : The mechanical and thermal properties of recycled post-consumer flexible polyethylene packaging waste was studied, using material collected and sorted on a large-scale from two sources. Unwashed, laboratory-scale washed, industrial-scale washed, and industrial-scale washed and melt-compounded (industrially recycled) materials were used. LÄS MER

  7. 20. Polymer Ionic Materials: A Study of new Materials for Solid Polymer Fuel Cells and Rechargeable Polymer Batteries

    Författare :Britta Mattsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PPO; polystyrene; neutron scattering; poly propylene oxide ; PEO; polymer electrolytes; poly vinylidene fluoride ; poly ethylene oxide ; luminescence; Raman spectroscopy; proton conducting polymer; poly styrene sulfonic acid ; PVDF;

    Sammanfattning : Ion-containing polymeric materials are interesting for use in a wide variety of applications, where the flexible, yet mechanically stable, polymer matrix is essential. Intensive research is presently going on worldwide for applications as electrolytes in solid polymer batteries and fuel cells, where the ion-conducting polymer also serves as an electrode separator.
