   Författare :Sebastian Buchmann; Anna Herland; Erica Zeglio; Agneta Richter-Dahlfors; Maria Asplund; KTH; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; organic bioelectronics; organic electrochemical transistors; conjugated polymers; microphysiological systems; in vitro cell models; Organisk bioelektronik; organiska elektrokemiska transistorer; Konjugerade polymerer; Mikrofysiologiska system; in vitro-modeller; Medicinsk teknologi; Medical Technology;

   Sammanfattning : Biological processes in the human body are regulated through complex and precise arrangements of cell structures and their interactions. In vivo models serve as the most accurate choice for biological studies to understand these processes. However, they are costly, time-consuming, and raise ethical issues. LÄS MER

3. 7. A Model System for Powder Injection Moulding – Physical Properties and Mould Filling Analysis

   Författare :Henrik Persson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; processing conditions; thermal properties; computer simulations; rheology; powder injection moulding; mould filling; jetting;

   Sammanfattning : ABSTRACTPowder injection moulding (PIM) is an important and accepted industrial technique for producing net-shaped components which combines the advantages of injection moulding and powder metallurgy. The properties of the feedstock, a mixture of powder and binder system (often based on a thermoplastic polymer), strongly influence the process. LÄS MER

4. 8. Catalytic conversion of biomass-derived synthesis gas to liquid fuels

   Författare :Rodrigo Suárez París; Magali Boutonnet; Agustín Martínez Feliu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuels; Fischer-Tropsch wax; higher alcohols; hydroconversion; kinetic modelling; methanol cofeeding; microemulsion; MoS2; noble metal; syngas; Chemical Engineering; Kemiteknik;

   Sammanfattning : Climate change is one of the biggest global threats of the 21st century. Fossil fuels constitute by far the most important energy source for transportation and the different governments are starting to take action to promote the use of cleaner fuels. LÄS MER

5. 9. Tailoring Adhesion and Wetting Properties of Cellulose Fibres and Model Surfaces Using Layer-by-Layer Technology

   Författare :Emil Gustafsson; Lars Wågberg; Gero Decher; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : The versatile layer-by-layer (LbL) technique, for consecutive adsorption of polyelectrolytes and charged nanoparticles onto a substrate, was used to modify cellulose fibres and model surfaces for improved mechanical and wetting properties. In addition to being used to modify cellulose substrates, the LbL technique was also used to create cellulose surfaces suitable for high resolution adhesion measurements. LÄS MER

7. 10. Manufacturing and Characterization of Filled Polymeric Systems

   Författare :Henrik Oxfall; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PS; hybrid composites; EBA; computer simulations; graphene; rheology; mould filling; graphite nanoplatelets; powder injection moulding; electrical conductivity; elongational flow; thermal properties; jetting;

   Sammanfattning : The physical properties are changed if fillers are added to a polymeric material. In this work a highly filled model system for power injection moulding (PIM) and graphite nanoplatelet (GNP) based nanocomposites have been manufactured and characterized. LÄS MER
