    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose; Nanofibers; Characterization; Homogenization; Endoglucanase; TEMPO; Specific surface area; Atomic force microscopy; Cellulosa; Nanofibrer; Karakterisering; Homogenisering; Endoglukanas; TEMPO; Specifik ytarea; Atomkraftmikroskopi; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The usage of wood has been a dominant driving force during the evolution of the human species. It allowed us to cook food, build tools, put roofs over our head and explore the world. The fibers making up the tree has been the most important way to store and transmit knowledge in the form of paper for centuries. READ MORE

  2. 2. Upconversion in Er doped silica : - characterization and modeling

    University dissertation from Kista : Mikroelektronik och informationsteknik

    Author : Dmitry Khoptyar; Bozena Jaskorszynska; Anders Bjarklev; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik; elektronik och fotonik; TECHNOLOGY Electrical engineering; electronics and photonics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik;

    Abstract : Further increase of erbium concentrations in Er-doped amplifiers and lasers is needed for the design of efficient, reliable, compact and cost-effective components for telecommunications and other photonic applications. However, this is hindered by Er concentration dependent loss mechanism known as upconversion. READ MORE

  3. 3. Novel Processing and Electrical Characterization of Nanowires

    Abstract : Polysaccharides are the most abundant biopolymers produced in nature and belong, together with proteins and nucleic acids, to the main components of life. Polysaccharides are polyhydroxylic polymers that can be functionalized by a wide selection of chemical reactions, and modifications of these biopolymers are applicable in the development of new materials.
