1. 1. Photocatalytic activity of titanium dioxide thin films deposited with high power impulse magnetron sputtering

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

   Författare :Victor Eriksson; [2021]
   Nyckelord :Photocatalysis; Titanium dioxide; Thin film; HiPIMS; Sputtering; Stearic acid;

   Sammanfattning : High power impulse magnetron sputtering has shown a lot of promise as a way of depositing photocatalytic thin films of titanium dioxide at low temperatures, however, the films deposited are often amorphous and display uncertain photocatalytic abilities. This thesis explores the deposition and characterization of photocatalytic thin films deposited with high power impulse magnetron sputtering. LÄS MER

3. 2. A novel chitosan-stearic coating with bee-pollen microcapsules for corrosion protection

   Kandidat-uppsats, KTH/Materialvetenskap

   Författare :Albin Andersson; [2020]
   Nyckelord :;

   Sammanfattning : In this project a novel chitosan-stearic acid (CS-SA) coating with bee-pollen microcapsules for encapsulation of 2-mecraptobenzothiazole (MBT) as a waterborne formulation for a biocompatible corrosion protection coating was developed and the coating properties was analyzed. Hydrophobic stearic acid (SA) was crosslinked with via a carbodiimide reaction to form micelles and is assembled on the bee- pollen grains and the chitosan matrix was further self-crosslinked using glutaraldehyde (GA).

4. 3. Self-assembly of Fatty Acids of Hair at the water-air interface

   Kandidat-uppsats, KTH/Materialvetenskap

   Författare :Marine Batista; [2020]
   Nyckelord :18-MEA; 18-methyl eicosanoic acid; Langmuir films; Langmuir-Blodgett films; AFM; Self-assembly; Branched fatty acid; Curvature; 18-MEA; 18-methyleikosansyra; Langmuir monoskikt; Langmuir-Blodgett; AFM; Självassociering; Förgrenad fettsyra; Krökning;

   Sammanfattning : 18-methyl eicosanoic acid (18-MEA), which is a branched fatty acid, is found at the outermost surface of mammalian hair with other straight-chain fatty acids such as palmitic acid and stearic acid. However, the precise role of 18-MEA is not yet completely understood. LÄS MER

5. 4. Field study of the drought’s impact on feeding strategy and biological parameters in early lactation dairy cattle

   Master-uppsats, SLU/Dept. of Animal Nutrition and Management

   Författare :Mikaela Würtz; [2019]
   Nyckelord :dairy cattle; drought; energy balance; feeding; metabolism;

   Sammanfattning : The summer of 2018 was unusually warm and dry. For animal production, this resulted in poor pastures, reduced harvests of crops, such as roughage and grains, and increased risk for heat stress in the animals. The drought led to problems as in shortage of animal feed, which made the feeding of dairy cattle difficult. LÄS MER

7. 5. Enzyme-aided production of lipid emulsifiers from side-streams of the food industry: rapeseed press cake and oat oil

   Master-uppsats, Lunds universitet/Bioteknik (master)

   Författare :Renske Bouma; [2017]
   Nyckelord :Lipid emulsifiers; enzymes; side-streams food industry; rapeseed press cake; oat oil; Technology and Engineering;

   Sammanfattning : The goal of this thesis project was to utilize side-streams of the food industry, namely rapeseed cake and oat oil, by enzyme-aided production of lipid emulsifiers. The first objective was to extract lipids from the rapeseed press cake and increase protein yield, by adding an enzymatic step to the already existing protein extraction procedure developed by the food department of Lund University.
