    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Controlled release; geopolymer; sol-gel; opioid; oral administration; oral dosage form; implant; titanium; hydroxyapatite; infection; strontium carbonate; strontium; Functional materials; Funktionella material; Materials science; Teknisk materialvetenskap; Material physics with surface physics; Materialfysik med ytfysik; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

    Sammanfattning : Ceramics are distinguished from metals and polymers by their inorganic nature and lack of metallic properties. They can be highly crystalline to amorphous, and their physical and chemical properties can vary widely. LÄS MER

  3. 2. Functional product development : an explorative view

    Författare :Åsa Ericson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Funktionella produkter; Functional Product Development; Computer Aided Design; Datorstödd maskinkonstruktion;

    Sammanfattning : Embodied in the concept of functional products is a shift in view for manufacturing companies as providers of physical artefacts to service providers. Furthermore, differentiation by offering added value, increased commitment towards customers, life-cycle commitment for the physical artefact and close collaboration between manufacturing companies are characteristics of the concept of functional products.
