  1. 1. Towards Affordable Sodium-Ion Batteries : Mechanochemical Synthesis and Electrochemical Assessment of Iron-Based Fluorophosphate Cathode Material

    Master-uppsats, KTH/Materialvetenskap

    Författare :Ratna Juwita; [2023]
    Nyckelord :Sodium-ion batteries; electrical energy storage EES ; iron oxide; positive electrode; material characterization; electrochemical; discharge capacity.; Natriumjonbatterier; elektrisk energilagring EES ; järnoxid; positiv elektrod; materialkarakterisering; elektrokemisk; urladdningskapacitet;

    Sammanfattning : An urgent transformation from fossil fuels to cleaner energy sources to combat climate change has led to the utilization of renewable energies like solar, wind, and tidal power. However, the intermittency of these sources hinders their wider implementation. To address this, large-scale electrical energy storage (EES) systems are needed. LÄS MER

  3. 2. Synthesis of glass-ceramic Li2S-P2S5-based electrolyte for solid-state batteries

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

    Författare :Leo Sjörén; [2023]
    Nyckelord :Solid electrolyte; Battery; sulphide; glass; electolyte; ball milling; ceramic; glass-ceramic; Batteri; elektrolyt; glas; glaskeram; svavel;

    Sammanfattning : In this project, solid sulphur based Li3PS4 electrolytes doped with Li4SiO4 were synthesised using two methods. In method A, a bought β-Li3PS4 electrolyte from Nei Corp was doped with 5 mole per cent Li4SiO4, resulting in a glass-ceramic electrolyte. LÄS MER

  4. 3. Evaluation of how text-to-speech can be adapted for the specific purpose of being an AI psychologist

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Pooya Rayat; Hugo Westergård; [2023]
    Nyckelord :Text-to-Speech Synthesis; AI Psychologist; Voice Traits; Conditional Speech Synthesis; Economic Impact of TTS Technolog;

    Sammanfattning : In this research, our goal was to pinpoint the crucial characteristics that make a voice suitable for an AI psychologist. More importantly, we wanted to explore how Text-To-Speech (TTS) combined with conditional voice controlling, also known as ”prompting”, could be used to incorporate these traits into the voice generation process.

  5. 4. Techno-Economic Assessment of High-Temperature H2O/CO2 : Co-Electrolysis in Solid Oxide Electrolysers for Syngas Production

    Master-uppsats, KTH/Kemiteknik

    Författare :Shivani Ramprasad Jambur; [2022]
    Nyckelord :Co-electrolysis; Power-to-X; Process modeling; Green Syngas; Solid-Oxide Electrolyser;

    Sammanfattning : High-temperature Co-electrolysis of H2O and CO2 in a solid-oxide electrolyser (Co-SOE) for syngas production is a high-efficiency renewable electricity conversion and storage method part of the Power-to-X technologies. Syngas, a mixture of H2, CO and CO2, is a critical building block to make several chemical and synthesis fuels. LÄS MER

  7. 5. Optimization and Characterization of Luminescent Materials for the ESS Proton Beam Imaging System

    M1-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Emelie Wiklund; Anton Järild; [2021]
    Nyckelord :Chemical Engineering; Luminescent materials; Cr-doped Alumina; Proton Beam Imaging System; ESS; Chemistry; Technology and Engineering;

    Sammanfattning : Spallation sources such as European Spallation Source (ESS) produces neutrons by bombarding high-energy protons onto the target wheel. To determine the location of the proton beam a Proton Beam Imaging (PBI) system will be installed. LÄS MER
