   Sammanfattning : Different sample preparation steps prior to a detection method are often essential in analytical chemistry. In this thesis, both static extractions and on-line coupled solid-phase extractions have been studied in combination with different detection techniques. LÄS MER

5. 29. Controlled Polymer Grafting from Nanoparticles for the Design of Dielectric Nanocomposites

   Författare :Martin Wåhlander; Eva Malmström; Anna Carlmark; Henrik Hillborg; Sanat K. Kumar; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : The interest for polymeric nanocomposites has rapidly grown during the last decades, fuelled by the great potential and superior properties of nanoparticles (NPs). The production volumes of commercial NPs have increased exponentially during the last ten years, and the quality has been significantly improved. LÄS MER

7. 30. Conducting Polymer-based Biohybrid Materials : Towards Microphysiological Chips and Soft Actuators for Bone Tissue Engineering

   Författare :Danfeng Cao; Edwin Jager; Jose Gabriel Martinez Gil; Jonathan Rossiter; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The human body is a complex system, consisting of different types of biomolecules and living matters, such as nucleic acids, proteins, carbohydrates, lipids, serum, cells, tissues, and organs. These complex biomolecules and living matters integrate and interact dynamically to perform and maintain body functions. LÄS MER
