  1. 1. Paper-based Supercapacitors

    Author : Britta Andres; Håkan Olin; Mats Sandberg; Mittuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; graphene; graphite; paper; nano fibrillated cellulose; supercapacitor; electric double-layer capacitor; energy storage; roll-to-roll; coating; kinetic energy recovery;

    Abstract : The growing market of mobile electronic devices, renewable off-grid energy sources and electric vehicles requires high-performance energy storage devices. Rechargeable batteries are usually the first choice due to their high energy density. However, supercapacitors have a higher power density and longer life-time compared to batteries. READ MORE

  2. 2. Design and Fabrication of Light-Emitting Electrochemical Cells

    Author : Andreas Sandström; Ludvig Edman; Ronald Österbacka; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Light-emitting electrochemical cell; fabrication; organic semiconductors; organic electronics; ambient fabrication; roll-to-roll; fysik; Physics;

    Abstract : Glödlampan, en gång symbolen för mänsklig uppfinningsförmåga, är idag på väg att försvinna. Lysdioder och lågenergilampor har istället tagit över då dessa har betydligt längre livstid och högre effektivitet. READ MORE

  3. 3. Foil-based Lab-on-Chip technologies for advanced Point-of-Care molecular diagnostics

    Author : Anna Ohlander; Aman Associate Professor; Christoph Professor; Anders Wolff; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Biotechnology; Bioteknologi; Medicinsk teknologi; Medical Technology; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : Infectious diseases pose a serious threat to global health. Molecular diagnostics provide solutions for effective control and prevention of infections, however suffers from expensive laboratory equipment, and infrastructure to be fully implemented at point of care (POC), especially at low-resource settings.
