2. 1. Superconducting kinetic inductance devices for nanoscale force sensing

   Author : August K. Roos; David B. Haviland; Hélène le Sueur; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optomechanics; force sensing; atomic force microscopy; kinetic inductance; superconductivity; strain; meandering nanowires; optomekanik; kraftavkänning; atomkraftsmikroskopi; kinetisk induktans; supraledning; töjning; slingrande nanotrådar; Material and Nano Physics; Material- och nanofysik;

   Abstract : In this thesis, we present a force sensor for atomic force microscopy based on cavity optomechanical principles. We explain the function, design, fabrication and characterisation of the force sensor. The mechanical part of the force sensor consists of a cantilever with a very fine tip. READ MORE

4. 2. On the quantification of healing in asphalt materials

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Healing; bitumen; mastic; viscoelastic strain; viscoplastic strain; fracture; creep and recovery; Läkning; bitumen; mastic; viskoelastisk töjning; viskoplastisk töjning; brott; kryp and återhämtning; Structural Engineering and Bridges; Bro- och stålbyggnad;

   Abstract : Asphalt materials exhibit self-healing characteristics. In order to evaluate the healing capabilities of these materials, numerous investigations are carried out by researchers. These investigations include various definitions of healing and mechanical test methods to quantify the extent of healing. READ MORE

5. 3. Materials and Devices for Stretchable Electronic Nerve Interfaces

   Author : Samuel Lukas Lienemann; Klas Tybrandt; Magnus Berggren; Diego Ghezzi; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stretchable electronics; Nanowires; Peripheral nerve interfaces; Cuff electrodes;

   Abstract : Within our body, there is a large network of nerves that facilitates communication between the brain and the body’s organs. This network is called our peripheral nervous system, consisting of soft and stretchable nerve bundles that gradually increase in their functional specificity as they split and branch out the closer they get to their target organ.

6. 4. Lignocellulose Biocomposites– A Comparison of Wood Fibers and Microfibrillated Lignocellulose

   Author : Erfan Oliaei; Lars Berglund; Tom S. C. Lindström; Fredrik Berthold; ‪Maria Soledad Peresin; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : All-lignocellulose composites, meaning densified fiber or fibril materials without added binder, show interesting mechanical properties and can be eco-friendly. Composites based on hot-pressed microfibrillated lignocellulose (MFLC) and lignocellulosic wood fiber (WF) reinforcements are compared with respect to processing, structure, mechanical properties, and eco-indicators.

   Abstract : En metod för dispersiv analys av försök med delad hopkinsonstång tillämpad på provning av granved vid hög töjningshastighetSyftet var att etablera en metod för att studera sambandet mellan spänning och töjning för granved vid hög töjningshastighet. Detta åstadkoms genom att anpassa och något vidareutveckla tekniken med delad hopkinsonstång ("Split Hopkinson Pressure Bar", SHPB). READ MORE
