2. 1. Organic Electrochemical Transistors : Materials and Challenges

   Author : Silan Zhang; Simone Fabiano; Magnus Berggren; Jenny Nelson; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The use of organic mixed ionic-electronic conductors (OMIECs) has demonstrated the potential to transform the field of bioelectronics, spanning from medical diagnostics to neuromorphic computing hardware. To keep up with the fast-paced demands, it is crucial to develop customizable device fabrication, design new materials, improve operation stability, and explore the ion-electron interactions within OMIECs.

4. 2. Hydrophobic Impregnation of Concrete Structures : Effects on Concrete Properties

   Author : Anders Selander; Johan Silfwerbrand; Jan Trägårdh; Mårten Janz; Andreas Gerdes; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrophobic impregnation; silane; siloxane; concrete; surface treatment; water repellent agent; building protection; impregnering; betong; silan; siloxan; ytbehandling; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

   Abstract : Hydrophobic impregnations often referred to as water repellent agents, today mainly consisting of alkylalkoxysilanes, are often used on concrete to prolong the service life of the structure. This is accomplished by protecting the reinforcement bars from chlorides or by changing the moisture content inside. READ MORE

6. 4. Chloride-based Silicon Carbide CVD

   Author : Henrik Pedersen; Erik Janzén; Anne Henry; Yaroslav Koshka; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

   Abstract : Silicon carbide (SiC) is a promising material for high power and high frequency devices due to its wide bandgap, high break down field and high thermal conductivity. The most established technique for growth ofepitaxial layers of SiC is chemical vapor deposition (CVD) at around 1550 °C using silane, SiH4, and lighthydrocarbons e g propane, C3H8, or ethylene, C2H4, as precursors heavily diluted in hydrogen.

7. 5. Advances in SiC growth using chloride-based CVD

   Author : Stefano Leone; Anne Henry; Erik Janzén; Calvin H. Jr Carter; Linköpings universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP;

   Abstract : Silicon Carbide (SiC) is a wide band-gap semiconductor. Similar to silicon it can be used to make electronic devices which can be employed in several applications. SiC has some unique features, such as wide band-gap, high hardness, chemical inertness, and capability to withstand high temperatures. READ MORE
