    Sammanfattning : Electrochemical deposition finds applications in the electronics- and protective coating industries. The technique is a versatile tool for the synthesis of alloys and thin films. Knowledge of the fundamental aspects of the electrode processes enables the design of nanostructured materials. LÄS MER

  4. 3. Assessment of environmental contaminants' neurotoxicity : in vitro and in vivo experimental studies

    Författare :Wan Norhamidah Wan Ibrahim; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Accumulating evidence over several decades shows that environmental contaminants may lead to neurodevelopmental alterations. An essential prerequisite to prevention is recognition of a chemical‟s ability to harm the developing nervous system. LÄS MER

  5. 4. Optical Amplifiers and their Applications in Nonlinear Fiber-Optic Communication Systems

    Författare :Kent Bertilsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The work presented in this dissertation deals with the characterization and modeling of optical amplifiers as well as their applications in nonlinear transmission systems with the main motivation to enhance system capacity. In the first part of the dissertation the work is focused on two different types of amplifiers: the semiconductor laser amplifier (SLA) and the erbium-doped fiber amplifier (EDFA). LÄS MER
