    Sammanfattning : Lithium-ion (Li-Ion) batteries are widely used in various applications and are viable for automotive applications. The effective management of Li-Ion batteries in battery electric vehicles (BEV) plays a crucial role in performance and range. LÄS MER

  3. 12. Theory of Time-Dependent Transport and Levitons in Nanowires

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik

    Författare :Jakob Westerberg; [2021]
    Nyckelord :leviton; Tkwant; tight-binding model; solid-state physics; time-dependent transport; scattering theory; quantum mechanics; computer simulation; nanowire; Physics and Astronomy;

    Sammanfattning : An interesting type of quasi-particles in solid-state materials are the so-called levitons. These are single- electron excitations above the Fermi-level that do not produce any hole states when carrying an integer multiple of the elementary charge. LÄS MER

  4. 13. Characterization of as prepared and exposed Perovskitesolar cells by microscopic and spectroscopic techniques

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Nagaraju Gorella; [2021]
    Nyckelord :Perovskites; Solar Cell; SEM; AFM; c-AFM; Photoluminescence; Electroluminescence; Solar simulator.;

    Sammanfattning : Studying the microstructural features, optical, and electrical properties of the thin-filmperovskite solar cells (PSC) is the main objective of this thesis work. All the PSCs used in thisthesis work were prepared by spin coating assisted with gas quenching process and the samplesreceived from Interuniversity Microelectronics Centre (IMEC), Belgium. LÄS MER

  5. 14. Study of solution-based Cs0.1FA0.9Pb(I0.9Br0.1)3 perovskite deposition with scalable technology for solar cell production : Characterization of optical properties and function of the solar cell

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fysikalisk kemi

    Författare :Tasnim Laskar; [2021]
    Nyckelord :;

    Sammanfattning : Climate change is one of the greatest challenges of the 21st century and is the reason for several environmental changes on earth. One reason behind climate change includes the rise ingreenhouse gas emissions in the atmosphere due to the burning of coal, gas and oil, i.e. fossil fuels. LÄS MER

  7. 15. Metformins potential att fördröja mänskligt åldrande

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Lotta Wiberg; [2021]
    Nyckelord :metformin; åldrande; livslängd; biologi;

    Sammanfattning : Humans have never before lived as long and we have never had as many cures and treatments for diseases as now. But we still spend the last years of our lives sick with age-related diseases. Some scientists say it is time to grasp the problem by its roots – which in this case is aging itself. LÄS MER
