1. Screening of HETP test conditions and resin storage solutions for HIC
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Analytisk farmaceutisk kemiSammanfattning : 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. LÄS MER
2. Evaluation of different block-copolymer coatings of iron oxide nanoparticles by flash nanoprecipitation
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : 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. Varnishing of Fiber-based Closures
Master-uppsats, Lunds universitet/FörpackningslogistikSammanfattning : 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. LÄS MER
4. Investigation of Milled Wood Lignin Extraction Using Enzymatic Hydrolysis for Application in Hydrophobic Barriers in the Food Packaging Industry
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : 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. LÄS MER
5. A novel approach for functionalising and separating Tröger's Base Analogues
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : 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. LÄS MER
