  1. 1. Pulse Amplitude Reconstruction in the LDMX Hadronic Calorimeter Readout

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Aksel Draguanov Mihaylov; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The universe shows signs of containing some invisible matter, known as dark matter. There are many possible constituents for dark matter, one such being light dark matter which would interact with ordinary matter through a new mediator force and have masses in the range of a few MeV to GeV.

    Sammanfattning : Researchers have estimated a 20-percentage point increase in the world’s population residing in urban areas between 2011 and 2050. The increase in denser cities results in opportunities and challenges. Two of the challenges concern sustainability and mobility. LÄS MER

  5. 4. Explorative Scenarios for Future Lithium Supplies and Demand

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Aksel Rahman; [2023]
    Nyckelord :lithium mining; lithium future production; Gompertz models; Richards models; Logistic models;

    Sammanfattning : Because of its specific qualities, lithium is a key element for making lithium-ion batteries, which is of great relevance since the battery sector is the fastest growing user of lithium to date and with the transition towards a fully electrified transportation sector due to the current climate agenda and an even bigger increase in demand for lithium is anticipated for the coming decades. The two main sources for lithium to date are mines and brines, with brine water composing around 87 % of the world’s lithium reserves in terms of contained lithium. LÄS MER
