  1. 1. Livscykelanalys av avloppsreningsverk : En jämförande studie mellan MBR och aktivslammetoden

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Ella Heinonen; [2023]
    Nyckelord :Membrane bioreactor; Environmental Impacts; Construction; Sewage treatment; Membranbioreaktor; Aktivt slam; Miljöpåverkan; Vattenrening; Konstruktion;

    Sammanfattning : Avloppsreningsverk är en viktig del av vattnets kretslopp och skyddar mottagande miljö från föroreningar i avloppsvattnet. Det finns olika tekniker att rena avloppsvattnet på och denna studie jämför den potentiella miljöpåverkan från MBR och aktivslammetoden ur ett livscykelperspektiv. LÄS MER

  3. 2. A new generation ofsmart food packaging : A combination of releasing anti-microbial and generation carbon dioxide inmeat packaging

    Master-uppsats, Karlstads universitet

    Författare :samar salahieh; [2023]
    Nyckelord :adsorption isotherms; desorption kinetics; benzoic acid; thymol; modified calcium carbonate; silica gel; carbon dioxide; food pad.; adsorptionsisotermer; desorptionskinetiken; bensoesyra; tymol; modifierat kalciumkarbonat; kisel gel; koldioxid; food pad.;

    Sammanfattning : Abstract Food sustainability depends significantly on packaging since it helps maintainfood safe and fresh throughout its shelf life, resulting in the least amount ofwaste and the least negative environmental impact. The main objective of thisstudy is to determine the adsorbed and released amount of antimicrobial agents(benzoic acid and thymol) on modified calcium carbonate (MCC) by investigating adsorption isotherm at 25°C and desorption kinetics at both 22°C and5°C of anti-microbial to identify potential solutions to enhance the long-termsustainability of fresh products such as meat.

  4. 3. Expression and purification of pyruvate transporting human mitochondrial pyruvate carrier (MPC) protein complex for structural studies

    Magister-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

    Författare :Markus Wendler; [2022]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Pyruvate is one of the main molecules needed for the citric acid cycle, which produces energy in the form of ATP. The citric acid cycle reaction occurs in the mitochondrial matrix, and for pyruvate to participate in the reaction, it needs to be transported from the cytosol across the mitochondrial membranes into the mitochondrial matrix.

  5. 4. 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

  7. 5. Evaluation of the stability of immobilized lipases from Rhizomucor miehei and Rhizopus oryzae in high oleic sunflower oil

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Jinxu Xu; [2021]
    Nyckelord :lipase; immobilization; oxidation; biotechnology; Technology and Engineering;

    Sammanfattning : Lipase is one of the most useful enzymes in food industry, which can catalyze the hydrolysis and the synthesis of esters. However, the high cost due to the poor operation stability of lipase hinders the wide use of it. LÄS MER
