  1. 1. Evaluation of different block-copolymer coatings of iron oxide nanoparticles by flash nanoprecipitation

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Felix Bogdan; [2023]
    Nyckelord :Nanopartiklar; organisk katalysator; ROP; block-sampolymerer PL G A; oljesyra IONPs; Nanoparticles; organic catalyst; ROP; block-copolymers PL G A; oleic acid IONPs;

    Sammanfattning : Nanopartiklar (NP) erbjuder unika möjligheter för medicinska tillämpningar, inklusive kontrollerad frisättning av cancerläkemedel, användning som bildkontrast vid avbildningsprocedurer eller hypertermisk behandling av cancerceller. Flash nanoprecipitation (FNP) producerar NPs för att kombinera dessa tillämpningar i en snabb, billig och skalbar beläggningsprocess. LÄS MER

  3. 2. Synthesis and Characterization of NCN Pincer Nickel Complexes

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Joel Klarén; [2023]
    Nyckelord :Pincer complexes; Nickel; organometallic chemistry; synthesis; NCN Pincer Nickel Complexes; organic chemistry; Chemistry;

    Sammanfattning : In this work, a series of nickel NCN complexes and ligands have been synthesized with the goal of determining whether they can perform so-called CO2-insertion reactions into Ni-C bonds. So far, only the synthesis of the Ni-Br precursor complexes to the previously mentioned Ni-C complexes have been synthesized. LÄS MER

  4. 3. Rare Earth Triflate/Alanine Catalysed Diels-Alder and Michael Reactions in Water and an Alternative Pyrrole Synthesis

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Albin Olsson; [2022]
    Nyckelord :Water; Green Chemistry; Synthesis; Organic Chemistry; Chemistry;

    Sammanfattning : Large amounts of organic solvents are used within the field of chemistry and nearly everything is being discarded and is not reused. A way to reduce the environmental impact that this leads to is to use a safe and natural solvent that is easy to access, like water. LÄS MER

  5. 4. Design of telechelic oligo-(caprolactone-co-dioxanone) as photocurable macromonomers for degradable gels

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Tran Tam Nguyen; [2020]
    Nyckelord :macromonomers; ring-opening co-oligomerization; telechelic co-oligomers; polymer; organocatalyst; makromonomerer; ringöppning samoligomerisering; telekelisk samoligomer; organisk katalysator;

    Sammanfattning : Three-dimensional (3D) printing has an important role for fabrication of degradable scaffoldsfor soft tissue regeneration. Among the 3D printing techniques, photopolymerization-based 3Dprinting is one of fastest growing, offering environmental benefits and high precision of 3Dobjects. LÄS MER
