  1. 6. Imaging materials with intermodulation : Studies in multifrequency atomic force microscopy

    Författare :Daniel Forchheimer; David Haviland; Arvind Raman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; atomic force microscopy; nonlinear dynamics; frequency mixing; force reconstruction; Fysik; Physics;

    Sammanfattning : The Atomic Force Microscope (AFM) is a tool for imaging surfaces at the microand nano meter scale. The microscope senses the force acting between a surfaceand a tip positioned at the end of a micro-cantilever, forming an image of the surface topography. LÄS MER

  3. 7. Carbon fibres from lignin-cellulose precursors

    Författare :Andreas Bengtsson; Monica Ek; Jim Parkås; Daniel Söderberg; KTH; []

    Sammanfattning : It is in the nature of the human species to find solutions of complex technical problems and always strive for improvements. The development of new materials is not an exception. One of the many man-made materials is carbon fibre (CF). LÄS MER

  4. 8. Polymer extraction and utilization of brown algal biomass

    Författare :Martin Sterner; Ulrica Edlund; Fredrik Gröndahl; Marguerite Rinaudo; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Algae; Saccharina latissima; alginate; brown seaweed; extraction; filament; chelation; gel; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Aquaculture is a field with a world changing potential. The areas at sea are enormous and aquatic cultivations impact both the environment and local ecology far less than land based cultivations. In the realm of algae, abundancies exists of nutrition, water and accessible sunlight, but there is constant shortage of places to dwell. LÄS MER

  5. 9. Nanostructured Biopolymeric Materials : Hydrodynamic Assembly, Mechanical Properties and Bio-Functionalities

    Författare :Nitesh Mittal; Daniel Söderberg; Chinedum Osuji; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : The need for high-end multifunctional materials from renewable resources has evolved given a rapidly increasing population and accompanying environmental concerns. Scalable assembly methods are and will be imperative in designing high-performance environmentally friendly materials, requiring new processes allowing control on all hierarchical levels. LÄS MER

  7. 10. Effect of high-temperature drying on spruce and larch Shape stability, mechanical properties and mould growth

    Författare :Eva Frühwald; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; twist; shape stability; Norway spruce; mould susceptibility; larch; high-temperature drying; distortion; Technological sciences; Teknik; Material technology; Materiallära; Building construction; materialteknik; heat-treatment; Byggnadsteknik; KSTRWood;

    Sammanfattning : Shape stability, the ability of the wood to retain its shape, is one of the most important parameters when using timber as a building material and for other applications. Generally, timber undergoes changes in dimensions and shape when its moisture content is changed. LÄS MER
