  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.

  2. 2. Precipitation of Carbides in a Ni-based Superalloy

    Magister-uppsats, Högskolan Väst/Avd för tillverkningsprocesser

    Författare :Sukhdeep Singh Handa; [2014]
    Nyckelord :Carbides; Superalloys;

    Sammanfattning : Alloy B is relatively new precipitation hardening superalloy. It´s applications are in the hot sections of the aero engines, rocket nozzles, gas turbines and in the chemical and petro-leum applications. The alloy is characterized by keeping high strength at elevated tempera-tures and high creep resistance. LÄS MER
