  1. 1. Screening of HETP test conditions and resin storage solutions for HIC

    University essay from Uppsala universitet/Analytisk farmaceutisk kemi

    Author : Lise-Lotte Ronnerfors; [2023]
    Keywords : Hydrophobic Interaction Chromatography; Pfizer Health AB; Column packing;

    Abstract : Hydrophobic interaction chromatography (HIC) is a common purification method for biological drug substances. For continuous monitoring the quality of the purification, a column performance test is carried out to test the packing of the resin. READ MORE

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

    University essay from KTH/Fiber- och polymerteknologi

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

    Abstract : 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. READ MORE

  3. 3. Varnishing of Fiber-based Closures

    University essay from Lunds universitet/Förpackningslogistik

    Author : Nisha Sunil David; [2023]
    Keywords : Varnishing; fiber-based closures; water-based spray coating; packaging; repulpability ; Technology and Engineering;

    Abstract : This research aims to investigate water-based varnishes and technologies to coat fiber-based closures to attain water barrier properties. To ensure recyclability the repulpability of coated and uncoated lids is tested. The research approach is exploratory. READ MORE

  4. 4. Investigation of Milled Wood Lignin Extraction Using Enzymatic Hydrolysis for Application in Hydrophobic Barriers in the Food Packaging Industry

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Anna Wagne; [2023]
    Keywords : Lignin; extraction; hydrophobicity; chemical engineering; Technology and Engineering;

    Abstract : The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. READ MORE

  5. 5. A novel approach for functionalising and separating Tröger's Base Analogues

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Emil Jakobsson; [2023]
    Keywords : Tröger s Base; Synthesis; Chromatography; Supramolecular chemistry; Diastereomers; Organic chemistry; Chemistry;

    Abstract : Tröger’s Base (TB) is a bicyclic compound containing a methanodiazocine group between two aromatic rings. The methylene bridge forces the molecule to have a bent formation; thus, the aromatic rings are close to 90 degrees relative to each other, resulting in a rigid concave aromatic cavity. READ MORE
