1. Paper-based Supercapacitors
Sammanfattning : 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. LÄS MER
2. Design and Fabrication of Light-Emitting Electrochemical Cells
Sammanfattning : 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. LÄS MER
3. Foil-based Lab-on-Chip technologies for advanced Point-of-Care molecular diagnostics
Sammanfattning : 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. LÄS MER
4. Probing the effects of photodegradation of acceptor materials in polymer solar cells: bulk, surface, and molecular level
Sammanfattning : Polymer solar cells (PSC) have reached record power conversion efficiencies of over 15%. The operational lifetime of PSCs, however, has to increase for their use in large area outdoor applications. LÄS MER
5. Improved inspection and micrometrology of embedded structures in multi-layered ceramics : Development of optical coherence tomographic methods and tools
Sammanfattning : Roll-to-roll manufacturing of micro components based on advanced printing, structuring and lamination of ceramic tapes is rapidly progressing. This large-scale and cost-effective manufacturing process of ceramic micro devices is however prone to hide defects within the visually opaque tape stacks. LÄS MER
