  1. 16. Automation of carbonyl index calculations for fast evaluation of microplastics degradation

    Kandidat-uppsats, KTH/Fysik

    Författare :Maja Walfridson; Emma Kuttainen Thyni; [2022]
    Nyckelord :FTIR; Carbonyl index; Degradation of microplastics; Microplastics; Automation;

    Sammanfattning : The broad use of plastics has resulted in the increase in both production and consequent plastic pollution in the environment. Microplastics, defined as particles < 5 mm, is of special interest because of its wide existence in environment and potential hazards to our ecosystem. LÄS MER

  3. 17. 3′-end fluorescence labelling of long RNAs using terminal deoxynucleotidyl transferase

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Johannes Lidberg; [2022]
    Nyckelord :Physical biochemistry; Fluorescence; In vitro transcription; RNA; Terminal deoxynucleotidyl transferase; Nucleobase analogue; Chemistry;

    Sammanfattning : Through recent years, RNA has rapidly gone from mainly being known as a passive information-carrying molecule within the central dogma of molecular biology to becoming the active ingredient in multiple therapeutics, such as in vaccines and potential drugs against cancer. However, one of the main challenges with RNA as a therapeutic is efficient delivery to cells. LÄS MER

  4. 18. Metoder för tjockleksmätning av kopparoxidskikt på kopparkapslar, samt tillverkning av referensprover

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

    Författare :Samuel Albertsson; [2022]
    Nyckelord :;

    Sammanfattning : Swedish Nuclear Fuel and Waste Management Company, SKB, main mission is to manage and take care of the Swedish nuclear waste. The method chosen is to store the waste far down in the ground in capsules made of copper, which needs to be intact for 100 thousands years. LÄS MER

  5. 19. Reducing cadmium emissions to water during removal of electrostatic precipitator ash : Investigating the effect of process parameters on the formation and precipitation of insoluble cadmium salts in water solutions

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Lukas Esperi; [2022]
    Nyckelord :cadmium; electrostatic precipitator ash; heavy metals; hydroxide precipitation; recovery boiler; elfilteraska; hydroxidfällning; kadmium; sodapanna; tungmetaller;

    Sammanfattning : The removal of electrostatic precipitator (ESP) ash by solving the ash in water constitutes an environmental problem if heavy metals, such as cadmium, present in the ash remain in the outgoing effluent streams. The ESP ash solution is alkaline, meaning cadmium is present as the insoluble salt Cd(OH)2, cadmium hydroxide. LÄS MER

  7. 20. Kadmiumhalter i svensk tång

    Kandidat-uppsats, Lunds universitet/Livsmedelsteknik (kandidat); Lunds universitet/Livsmedelteknisk högskoleutbildning - YTH

    Författare :Jonathan Laike Ståhle; Emil Jonsson; [2022]
    Nyckelord :Cadmium; Sea weed; Sacchariana latissima; Ulva intestinalis; Fusus serratur; Boiling; AAS; ICP-OES; Food Technology; Agriculture and Food Sciences; Chemistry;

    Sammanfattning : Seaweed along the Swedish coast contains both proteins, fats, vitamins and minerals, and could be part of the food supply of the future. It could also be described as climate smart as seaweed does not need to be watered, fertilized, or take up land for cultivation. LÄS MER
