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. The thermal insulating effects of Quartzene® on painting systems

   Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

   Författare :Arwin Zendehrokh; Luis Mariscal; Martin Hunhammar; Ismail Yussuf Hassan; Albert Pettersson; [2020]
   Nyckelord :aerogel; quartzene; insulation; nanoparticles; paint; Transient plane source; TPS; thermal conductivity;

   Sammanfattning : The European Green Deal 2020 goals for reducing emissions are enforcing rules on the energy performance of buildings. Therefore thermally insulating materials used as coatings are researched to reduce the energy emissions of buildings. An essential field of interest are nanomaterials. LÄS MER
