16. Solution-processed light-emitting electrochemical cells : challenges and opportunities
Sammanfattning : Our world is filling up with electronics. High-tech gadgets are integrated everywhere, from smart fridges able to track expiry dates and food usage, to microchip implants that let us unlock doors and pay with our hands. LÄS MER
17. Numerical Study of the Gas Flow and Heat Transfer during Electromagnetic Stirring and Post Combustion in EAFs
Sammanfattning : The effect of electromagnetic stirring on scrap melting and post combustion in two different electric arc furnaces (EAFs) have been studied using numerical modelling. The effect of electromagnetic stirring on melting of a piece of scrap located at the eccentric bottom tapping (EBT) region of an EAF has been studied. LÄS MER
18. Electrical Characterization of Silicon Nanogaps
Sammanfattning : We have designed and manufactured silicon nanogaps aimed at electrically interfacing molecules, utilizing the precision thickness control in an oxidation process. An insulating layer was formed on a silicon wafer, and then polysilicon was deposited on top. LÄS MER
19. The Complex Nature of the Electrode/Electrolyte Interfaces in Li-ion Batteries : Towards Understanding the Role of Electrolytes and Additives Using Photoelectron Spectroscopy
Sammanfattning : The stability of electrode/electrolyte interfaces in Li-ion batteries is crucial to the performance, lifetime and safety of the entire battery system. In this work, interface processes have been studied in LiFePO4/graphite Li-ion battery cells. LÄS MER
20. Materials and Device Engineering for Efficient and Stable Polymer Solar Cells
Sammanfattning : Polymer solar cells form a promising technology for converting sunlight into electricity, and have reached record efficiencies over 10% and lifetimes of several years. The performance of polymer solar cells depends strongly on the distribution of electron donor and acceptor materials in the active layer. LÄS MER
