  1. 1. Modified cellulose synthesized by different deep eutectic solvents as an additive in paper making process

    Master-uppsats, Karlstads universitet

    Författare :Shiniar Said Saleh; [2023]
    Nyckelord :green chemistry; dry strength additives; deep eutectic solvents; sodium periodate oxidation; charge density; dewatering; mechanical strength.;

    Sammanfattning : The environmental concerns that come with the currently used traditional papermaking process where petroleum-based additives are used, has tempted researchers to study “green” additives by introducing environmentally friendly modifications of cellulose as an additive in the papermaking process. This thesis will spin further on that by producing additives with different charge densities and focus on to incorporate an etherification reaction into potentially greens systems based on non-toxic and readily biodegradable deep eutectic solvent (DES).

  3. 2. Investigating Brønsted Acidic Deep Eutectic Solvents for Recycling of Lithium Cobalt Oxide

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Mattias Lindgren; [2022]
    Nyckelord :Deep eutectic solvents; Recycling; Lithium-Ion Batteries; Cathode Materials; LCO;

    Sammanfattning : Recently, the production of lithium-ion batteries (LIB) has grown rapidly, highlighting the need for efficient and environmentally friendly recycling of LIB waste. In this work, the usage of so-called deep eutectic solvents (DESs) for the leaching of the LIB cathode material lithium cobaltoxide is investigated. LÄS MER

  4. 3. Deep Eutectic Solvents and Their Possible Application in Transdermal Drug Delivery

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Sarah Lindblom; [2020]
    Nyckelord :Deep Eutectic Solvents; Pharmaceuticals; Transdermal drug delivery; Choline Chloride; Rheology; Formulation; BSA; Franz cell diffusion; Pharmaceutical technology; Läkemedelsteknologi; Technology and Engineering;

    Sammanfattning : Deep eutectic solvents, DES, is a type of solvent made by mixing a quaternary ammonium salt with a hydrogen bond donor at the eutectic point of the system. Most common quaternary ammonium salt is Choline Chloride, ChCl. A specific DES, Choline:CAGE has shown promise in delivering insulin through the skin of mice. LÄS MER
