   Sammanfattning : Soft matter, here, liquids and polymers, have adaptability to a surrounding geometry. They intrinsically have advantageous characteristics from a mechanical perspective, such as flowing and wetting on surrounding surfaces, giving compliant, conformal and deformable behavior. LÄS MER

3. 12. Studies of Materials and Interfaces for Organic Electronics

   Författare :Slawomir Braun; William R. Salaneck; Ian McCulloch; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organic electronic; Polymeric materials; Organic light-emitting diodes OLEDs ; Organic fieldeffect transistors OFETs ; Organic solar cells; Material physics with surface physics; Materialfysik med ytfysik;

   Sammanfattning : Organic electronics is a rapidly evolving field with vast number of applications having high potential for commercial success. Although a great progress has been made, many organic electronic applications: organic light-emitting diodes (OLEDs), organic fieldeffect transistors (OFETs), organic solar cells, etc; still require further optimization to fulfill the requirements for successful commercialization.

4. 13. Rough surfaces in contact : artificial intelligence and boundary lubrication

   Författare :Marco Rapetto; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

   Sammanfattning : Interacting surfaces are found in mechanical systems and components. Since engineered surfaces are not perfectly smooth, only a fraction of the nominal surface area is actually in contact. This fraction is denoted as the real area of contact, Ar, and is formed by the sum of the contact spots between the two touching surfaces. LÄS MER

5. 14. Topographical Impact on Space Charge Injection, Accumulation and Breakdown in Polymeric HVDC Cable Interfaces

   Författare :Espen Doedens; Chalmers tekniska högskola; []
