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. Electrolytic Reduction of Iron Oxides in Molten Salt with a Mineralogical Investigation of Magnetite Ore of Tapuli
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : This master's thesis covers an investigation of the reduction behavior of different iron oxides when electrolytically reduced with molten salt electrolysis (MSE). The tested iron oxides were wüstite (FeO), hematite (Fe2O3), magnetite (Fe3O4) and magnetite ore concentrate from the Tapuli deposit in Pajala, Norrbotten, Sweden. LÄS MER
3. Wet Spinning of Cellulose-Lignin Precursor for Carbon Fibers : Effect of Coagulation Bath Composition & Spin Finish
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanikSammanfattning : Carbon fibers (CF) are a material with a composition of over 90% carbon, which has high mechanical properties and low density. This unique combination of properties makes it requirable in applications such as vehicles, aerospace, wind power, and space industries. Commercially made CF are made using the fossil raw material polyacrylonitrile (PAN). LÄS MER
4. The Examination of Alternative Methods for Sperm Cell Lysis and Purification of Sexual Assault Samples
Master-uppsats, Lunds universitet/Teknisk mikrobiologiSammanfattning : Forensic sexual assault samples typically contain a mixture of a small quantity of sperm cells and a high quantity of epithelial cells. This relationship complicates the generation of a DNA profile, which prompts the need for differential lysis and extraction of the DNA. LÄS MER
5. Urea-Based Treatments of Unretted Hemp Fibres from Residual Streams
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : More sustainable and efficient degumming methods are required to extract finner bast fibres, especially from agro-industrial waste streams such as stalks from hemp for food purposes. For this reason, in this study, two urea-based treatments were evaluated as degumming alternatives for unretted hemp fibres from residual streams, one at cold and alkaline conditions (CUA) and the other in combination with microwave radiation (MWU).
