  3. 12. All-organic aqueous Na-ion energy storage devices

    Författare :Martin Karlsmo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid supercapacitor; battery; battery supercapacitor hybrid; aqueous electrolyte; All-organic; Na-ion capacitor; energy storage;

    Sammanfattning : Development of all-organic aqueous energy storage devices (ESDs) is a promising pathway towards meeting the needs of technically medium/low-demanding electrical applications. These ESDs should favour low cost, low environmental impact, and safety, and thus complement high voltage and energy/power dense storage such as lithium-ion batteries. LÄS MER

Self-assembly is an easily scalable alternative to conventional manufacturing. LÄS MER

  5. 14. User-Centred Design and Technology-Mediated Services- Identifying and Addressing Challenges by Analysing Activities

    Författare :Oskar Rexfelt; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; technology-mediated services; product development; user requirements; User-centred design; service development; user studies;

    Sammanfattning : User-centred design has a focus on designing products to satisfy user needs rather than emanating from a technological starting point. Understanding user needs when developing products is considered a key component to achieve market success today.User-centred design is almost always described as a way to design products that satisfy user needs.
