  6. 9. Functionalized Porous Carbon Fiber Electrodes for Applications in Electrochemical Flow Cells

    Author : Arman Molaei; Xavier Crispin; Magda Titirici; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon-based devices; Supercapacitor; Deoxygenation electrolyser; BBL polymer;

    Abstract : Corrosion of metals in close-loop cooling or heating systems originates from tiny leakages at joints releasing oxygen into the thermal fluids. The presence of dissolved oxygen (DO) in thermal fluids, such as water with various additives forms a rust coating and some rust particles are released in the fluids and accumulate in an undesired place.

  7. 10. Inkjet Printing of Graphene-based Microsupercapacitors for Miniaturized Energy Storage Applications

    Author : Szymon Sollami Delekta; Mikael Östling; Jiantong Li; Donald Lupo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet printing; graphene; supercapacitor; microsupercapacitor; energy storage; printed electronics; printing technologies; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Printing technologies are becoming increasingly popular because they enable the large-scale and low-cost production of functional devices with various designs, functions, mechanical properties and materials. Among these technologies, inkjet printing is promising thanks to its direct (mask-free) patterning, non-contact nature, low material waste, resolution down to 10 µm, and compatibility with a broad range of materials and substrates.
