    Abstract : Tactile perception is considered an important contributor to the overall consumer experience of a product. However, what physical properties that create the specifics of tactile perception, are still not completely understood. READ MORE

  2. 2. Synthesis of degradable aliphatic polyesters: strategies to tailor the polymer microstructure

    Author : Jenny Fagerland; Anna Finne-Wistrand; David Kaplan; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer synthesis; enzymatic synthesis; degradable polyesters; peptides; scaffolds; Chemical Engineering; Kemiteknik;

    Abstract : Key factors for successful tissue engineering are the synthesis and design of the scaffold materials. Aliphatic polyesters have been studied and often used as scaffold materials for tissue engineering. However, their lack of biological cues and degradation under high-temperature processing (e.g. READ MORE

  3. 3. Predator-prey interactions in freshwater systems: The importance of chemical communication

    Author : Kajsa Åbjörnsson; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi; Ecology; Ekologi; Hydrobiology; trophic cascades; non-lethal effects; benefits; costs; heredity; predator experience; alarmsubstances; dietary cues; amphibian larvae; invertebrates; visibility; fish; behaviour; Predator-prey; chemical cues;

    Abstract : Predator released chemical cues provide a valuable source of information to prey organisms that can be used to alter their behaviour in order to reduce predation risk. In this thesis, I have examined under what circumstances chemical cues may be used by prey, and if prey discriminate between different cues. READ MORE

  4. 4. Some Approaches to Eco-Friendly Products from Natural Matrices

    Author : Joel Ljunggren; Erik Hedenström; Olav Martin Kvalheim; Mittuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Since the onset of the industrial and chemical revolution, humans have caused immense damages to the surrounding flora and fauna. Effective methods for wood protection measures proved to be toxic; fossil fuels contribute to global warming and pesticides can be detected in the air, water, and soil. READ MORE

  5. 5. Nano and Micro Patterned Organic Devices : From Neural Interfaces to Optoelectronic Devices

    Author : Tobias Nyberg; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis describes fabrication methods for optoelectronic devices (light emitting diodes (LEDs) and photodiodes) and structures for neural interfacing (neural electrodes and nerve guidance structures) using semiconducting and conducting organic materials as the active elements. Special importance has been attached to the patterning and processing of these devices. READ MORE
