1. 16. Characterization of Low Cost Printed Sensors for Smart Packaging

   Författare :Tomas Unander; Hans-Erik Nilsson; Bengt Oelmann; Mats Robertsson; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

   Sammanfattning : Currently there are very significant interests in printed electronics in the world. The possibility to produce electronics in a roll to roll printing process will considerably reduce the cost of the electronic devices. LÄS MER

3. 17. Enhanced boiling heat transfer from a novel nanodendritic micro-porous copper structure

   Författare :Richard Furberg; Björn Palm; Mats Strömblad; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal energy engineering; Termisk energiteknik;

   Sammanfattning : Following licentiate thesis is a summary of the advances made within the research project - Micro- and nano structured surfaces for enhanced boiling heat transfer – which is a collaboration effort between the Divi-sion of Applied Thermodynamics and Refrigeration and the Division of Materials Chemistry at the Royal Institute of Technology (KTH). The main objectives with this research project has been to: develop methods for producing highly efficient boiling surfaces with well defined micro- and nano-structured porous surfaces by the use of micro- and nano-manufacturing techniques.

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X-ray Free Electron lasers XFELs ; 3D electron density determination; Machine learning; Image processing; High-performance computing; GPUs; Uncertainty quantification; X-ray single-particle Imaging; Flash X-ray single-particle diffraction Imaging FXI ; ; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

   Sammanfattning : Modern X-ray Free Electron Laser (XFEL) technology provides the possibility to acquire a large number of diffraction patterns from individual biological nano-particles, including proteins, viruses, and DNA. Ideally, the collected data frames are high-quality single-particle diffraction patterns. LÄS MER

7. 20. From Responsive Interfaces to Honeycomb Membranes by Controlled Radical Polymerisation

   Författare :Daniel Nyström; Anders Hult; Søren Hvilsted; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Isoporous membranes; Silica nanoparticles; ATRP; Functional surfaces; cellulose; Polymer chemistry; Polymerkemi;

   Sammanfattning : In this study, surface modification of both organic and inorganic substrates (in terms of cellulose and silica nanoparticles, respectively) has been explored using surface-initiated atom transfer radical polymerisation (ATRP). The desire to modify bio-based materials to fit into new application areas and the need for bio-based materials with improved material properties is steadily increasing due to environmental concern.
