  4. 4. Flexible and Cellulose-based Organic Electronics

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Jesper Edberg; Linköpings universitet.; Linköpings universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; conductive polymers; nanocellulose; nanofibrillated cellulose; composite materials; paper electronics; flexible electronics;

    Sammanfattning : Organic electronics is the study of organic materials with electronic functionality and the applications of such materials. In the 1970s, the discovery that polymers can be made electrically conductive led to an explosion within this field which has continued to grow year by year. LÄS MER

  5. 5. Environmental Implications of Product Servicising. - The Case of Outsourced Computing Utilities

    Detta är en avhandling från International Institute for Industrial Environmental Economics, Lund University

    Författare :Andrius Plepys; Lund University.; Lunds universitet.; [2004]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; life cycle assessment; electronics; computers; semiconductors; server-based computing; Application Service Provision.; Commercial and industrial economics; Industriell ekonomi; Electronics; Dematerialisation; product servicising; Elektronik;

    Sammanfattning : The life cycle of electronic products is associated with significant environmental impacts. Compared to many other products, the production of electronics and in particular semiconductors is resource intensive and generates a number of highly toxic waste streams in manufacturing and post-consumer stages of product life cycle.
