1. 1. Organic Electronics and Microphysiological Systems to Interface, Monitor, and Model Biology

   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. 2. Voltage Stabilizers: From Design to Synthesis, Processing and Electrical Characterization

   Författare :Markus Jarvid; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Polyethylene; Degradation; XLPE; Electrical treeing; Voltage stabilizer; Cable; Insulation;

   Sammanfattning : Voltage stabilizers are additives capable of inhibiting electrical treeing; a degradation mechanism for insulation materials subjected to strong divergent electric fields. The intended use is in cross-linked polyethylene (XLPE) high voltage power cable insulation where minute defects in the manufacturing process can give rise to the conditions needed for the initiation of treeing, which in the worst case scenario leads to failure of the insulation system with blackouts and expensive repairs as a consequence.

4. 3. Electrochemical reduction of protons and organic molecules in hydrogen technologies : Liquid Organic Hydrogen carrier and Hydrogen Evolution

   Författare :Hamid Ghorbani Shiraz; Magnus Berggren; Xavier Crispin; Ola Wendt; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrogen Storage; LOHC; Hydrogen Evolution; Electrocatalyst;

   Sammanfattning : In accordance with preventable actions to mitigate the effect of climate change in the modern societal applications, renewable energy is an unavoidable and decisive factor in the energy industry. The energy sources that offer non-depleted and environment-friendly pathways for the energy sector are in focus. LÄS MER

5. 4. Hybrid Materials for Wearable Electronics and Electrochemical Systems

   Författare :Mehmet Girayhan Say; Isak Engquist; Magnus Berggren; Shizuo Tokito; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wearables; Green electronics; Organic electronics; Conductive polymers;

   Sammanfattning : Flexible electronic systems such as wearable devices, sensors and electronic skin require power sources and sensing units that are mechanically robust, operational at low bending radius, and environmentally friendly. Recently, there has been an enormous interest in active materials such as thin film semiconductors, conductive polymers, and ion-electron conductors. LÄS MER

7. 5. Organic Bioelectronics for Neurotransmitter Release at the Speed of Life

   Författare :Theresia Arbring Sjöström; Magnus Berggren; Daniel Simon; Klas Tybrandt; Marco Rolandi; Linköpings universitet; []
