1. 1. Development of covalent organic frameworks for energy storage applications : DAAQ-TFP COF and MXene composite electrodes for proton cycling

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

   Författare :Simanjit Singh; [2022]
   Nyckelord :covalent organic framework; DAAQ-TFP; MXene; composite electrodes; 1 3 5-Triformylphloroglucinol; 2 6-Diaminoanthraquinone; nanosheets; exfoliation; ex-situ; Ti3C2Tx;

   Sammanfattning : The demand for today's material resources for energy storage is rapidly increasing and can result in both environmental and political conflicts that can affect the development of electronic devices due to high prices and limitations of raw materials for batteries. In this study, potential future composite electrodes were synthesised with an ex-situ approach by compositing redox-active 2,6-Diaminoanthraquinone and 1,3,5-Triformylphloroglucinol covalent organic framework (DAAQ-TFP COF) with conductive delaminated Ti3C2Tx MXene to maximise the number of redox-active moieties during cycling.

3. 2. Svavelcirkulation i cementprocessen längs ugnslinje 7

   Kandidat-uppsats, Uppsala universitet/Institutionen för kemi - Ångström

   Författare :Simanjit Singh; Lovisa Rova; Jennifer Andersson; [2020]
   Nyckelord :Cement; Svavel; cyklontorn; Svavelbalans; Påbakningar;

   Sammanfattning : Cement is produced in three main steps: grinding of a mixture of raw materials, sintering of the raw meal to form clinker, and grinding and mixing of clinker, gypsum and additives to make cement. Slag from steel manufacturing can be used to replace some of the raw material, but since slag is a carrier of some unwanted compounds, problems arise. LÄS MER
