1. Exploring alternative surfactants to replace PEG within lipid nanoparticles
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master); Lunds universitet/Bioteknik (CI); Lunds universitet/Bioteknik (master)Sammanfattning : Over the past decade an increasing amount of studies has demonstrated that PEGylation not only precipitates reductions in drug delivery efficiency but also triggers the immune system to produce antibodies, specifically anti-PEG antibodies. The objective of my thesis is to explore alternative surfactants that could viably replace PEG within lipid nanoparticles. LÄS MER
2. Green Coacervates for Pharma and Food
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)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
3. Evaluation of PFAS removal from nanofiltration membrane concentrate using foam fractionation
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Per- and polyfluorinated substances (PFASs) have become an urgent topic in the water treatment industry in recent years as a consequence of new scientific discoveries of the correlation between the ingestion of some PFASs and their toxicity in humans and other organisms. PFASs are synthetic compounds present in a variety of products. LÄS MER
4. Magnetic Ionic Liquids in Solutions and Emulsions
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : This research thesis reports experimental work done to design a stable magneticmicroemulsion of ionic liquid in 2-ethylhexyl laurate with the help of an ionic surfactant andan alcohol co-surfactant. The ionic liquids tested were based on a 1,3-dialkylimidazoliumcation with different alkyl chain lengths and a tetrachloroferrate anion ([FeCl4]+) to ensure theemulsion is sensitive to applied magnetic fields.

5. Lungutveckling och surfaktant : lammets perinatala överlevnad
Kandidat-uppsats, SLU/Dept. of Anatomy, Physiology and BiochemistrySammanfattning : En lamning kräver ofta en hel del arbete av tackan och ibland även av djurägaren innan lammet piggnar till efter födseln och kan ta sig upp på egna ben för att dia. Komplikationer vid lamning är inte helt ovanligt och kan göra processen lång, uttröttande och smärtsam för både tacka och lamm. LÄS MER
