  1. 11. Tuned sustainable anodic coatings for reduced ice adhesion

    University essay from Linköpings universitet/Molekylär ytfysik och nanovetenskap

    Author : Thirza Poot; [2019]
    Keywords : aluminum alloys; tartaric-sulfuric acid anodizing; ice adhesion; silanization; hydrothermal sealing; contact angle; SEM; corrosion;

    Abstract : Aluminum alloys are widely used materials in the aircraft industry due to their high specific strength and durability. The natural corrosion resistance of aluminum can be improved through an electrochemical anodizing process. READ MORE

  3. 12. Electro-Optical Characterization of Passivated InAsP/InP Quantum Discs-in-Nanowire Heterostructures

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Samareh Kordi Jazi; [2018]
    Keywords : Physics and Astronomy;

    Abstract : Semiconductor nanowires, with their quasi one-dimension geometry, inherently provide strain relaxation for heterogeneous integration and also strong light mode confinement. Nanowire-based photonic devices have also been demonstrated to offer significantly enhanced quantum efficiency, gain and reduced noise. READ MORE

  4. 13. Digitally Controlled Oscillator for mm-Wave Frequencies

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Rikard Gannedahl; Johan Holmstedt; [2018]
    Keywords : RF; RFIC; oscillator; DCO; mm-wave; Technology and Engineering;

    Abstract : In the fifth generation of mobile communication, 5G, frequencies above 30 GHz, so-called millimeter-wave (mm-wave) frequencies are expected to play a prominent role. For the synthesis of these frequencies, the all-digital phase locked loop (ADPLL) has recently gained much attention. READ MORE

  5. 14. Lifetime estimation of lithium-ion batteries for stationary energy storage system

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Joakim Andersson; [2017]
    Keywords : Li-ion battery; State of charge; State of health; Kalman filtering; Energy Storage;

    Abstract : With the continuing transition to renewable inherently intermittent energy sources like solar- and wind power, electrical energy storage will become progressively more important to manage energy production and demand. A key technology in this area is Li-ion batteries. READ MORE

  6. 15. Prediction and analysis of model’s parameters of Li-ion battery cells

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Ali Dareini; [2016]
    Keywords : Lithium-ion battery; equivalent circuit model; electrochemical model; AutoLion software; predicting and analysis of parameters; key parameters; tuning the parameter; knowledge-based data; physical and chemical measurements; physical tests; EIG C20;

    Abstract : Lithium-ion batteries are complex systems and making a simulation model of them is always challenging. A method for producing an accurate model with high capabilities for predicting the behavior of the battery in a time and cost efficient way is desired in this field of work. READ MORE
