  1. 1. Effects of mixed surfactant system on chemical and physical stability of human growth hormone

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

    Författare :Karnsinee Viriyayudhakorn; [2023]
    Nyckelord :human growth hormone; surfactant; refolding; protein stability; physical degradation; chemical degradation; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : In protein formulation, addition of surfactants is commonly executed to enhance product stability and shelf-life. The reason is that surfactants can protect proteins against surface-induced aggregation. However, the interaction between surfactant and protein depends on the type of surfactant used. LÄS MER

  3. 2. 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).

  4. 3. Undersökning av nyckeltal vid kemisk fällning av fosfor med järnklorid

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Erika Montelius; [2022]
    Nyckelord :Kemisk fällning; järnklorid; fosforrening; avloppsvattenrening;

    Sammanfattning : Himmerfjärdsverket i Grödinge drivs av Syvab vars uppgift är att ta emot och rena avloppsvatten. Vattnet renas från organiskt material, kväve och fosfor och släpps sedan ut till Syvabs recipient Himmerfjärden. Syftet är att skydda miljön mot utsläpp som kan påverka Östersjön och minska övergödningen. LÄS MER

  5. 4. Green Coacervates for Pharma and Food

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

    Författare :Izabella Imets; Andreas Vallin; [2022]
    Nyckelord :MSc; coacervate; biosurfactant; biopolymer; SAXS; DLS; elliposometry; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : Anionic biosurfactant-cationic biopolymer systems were investigated to identify and characterize a coacervation window. The characterization of the systems was performed with dynamic light scattering, small angle x-ray scattering and in-situ ellipsometry. LÄS MER

  7. 5. Drug Design of β-Lactamase Inhibitors of the DBO-scaffold against OXA-48 : A Molecular Dynamics Study of Ligand Stability in the Michaelis Complex

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Läkemedelsdesign och läkemedelsutveckling

    Författare :Linda Liljeholm; [2022]
    Nyckelord :OXA-48; β-lactamase; DBO inhibitors; diazabicyclooctane; avibactam; relebactam; β-lactamase inhibitor; BLI; molecular dynamics; LIE; Linear Interaction Energy; antibiotic resistance; drug design;

    Sammanfattning : The emergence of β-lactamase-mediated antibiotic resistance is one of the biggest threats in modern times. Combined with the discovery void of new forms of antibiotics, this sets the course toward a future where the efficacy of present-day health care will be jeopardized. LÄS MER
