  1. 1. Investigating self-discharge in a graphite dual-ion cell using in-situ Raman spectroscopy.

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Ismail Yussuf Hassan; [2023]
    Nyckelord :graphite; dual-ion battery; parasitic reaction; cathode-electrolyte interface; anion intercalation; concentrated electrolyte; self-discharge; Raman spectroscopy;

    Sammanfattning : Anion intercalation in the graphite positive electrode of a dual-ion battery requires high potential (> 4.3 V vs Li+/Li), which aggravates parasitic reactions involving electrolyte decomposition and Al corrosion, manifesting in poor coulombic efficiency, cycle life, and quick self-discharge.

  3. 2. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :William Gulding; [2023]
    Nyckelord :Adsorption; D-Rainclean; metal removal; Reactive filter; stormwater treatment;

    Sammanfattning : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. LÄS MER

  4. 3. Electromagnetic compatibility of unmanned aircraft : Examination of legislation and evaluation of two commercial systems

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Alex Bergdahl; [2022]
    Nyckelord :Electromagnetic compatibility; Unmanned aircraft; Electromagnetic compatibility legislation;

    Sammanfattning : Electromagnetic compatibility (EMC), or the field of reducing emissions from and increasing immunity against electromagnetic interference, is an essential part of designing modern electronics. As one would expect, EMC is especially important for things such as aircraft and aviation equipment where outages or disturbances could have severe consequences. LÄS MER

  5. 4. SuDS water storage capacity calculator : A decision support tool for the implementation ofSustainable Drainage Systems in Östersund.

    Master-uppsats, Mittuniversitetet/Institutionen för ekoteknik- och hållbart byggande

    Författare :Tess van der Hulle; [2022]
    Nyckelord :Sustainable Drainage Systems SuDS ; Decision Support Systems DSS ; precipitation; calculator; stormwater model; Östersund; Sweden;

    Sammanfattning : Heavy precipitation events are expected to increase in intensity and frequency, due to global warming. Sewer systems might overload during heavy rainfall, resulting in floods which potentially affect all municipalities in Sweden. LÄS MER

  7. 5. Carnot Batteries as a Power-to-X-to-Power Alternative : A Study on Optimization of Thermal Energy Storage Usage

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :ERIK FORSMAN; [2021]
    Nyckelord :;

    Sammanfattning : The implementation of renewable energy sources continues the rise throughout the world as a means to combat the threats of climate change. This does however bring with it problems within the power sector. LÄS MER
