1. Effect of the Cooling Rate and the Surface Film Composition on the Colloidal Stability of Whey Protein Based Emulsions of Triacylglycerols
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : The goal of this project was to investigate the effect and interplay of formulation and processing parameters on the colloidal stability of emulsified triacylglycerols from a product quality perspective. Different methods to quantify and monitor this effect over time were evaluated. LÄS MER
2. Electron Assisted Growth of h-BN on Gr/Ir(111)
Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : Stacked heterostructures of two-dimensional (2D) materials are emerging as promising building blocks for a wide range of applications. These devices, which range from tunneling transistors to light-emitting diodes, use the properties of 2D materials that are not accessible by their bulk counterparts. LÄS MER
3. IMPACT OF CRYOPRESERVATION MEDIA ON SPERM MOTILITY
Kandidat-uppsats,Sammanfattning : The result of cryopreservation of semen is crucial for patients in need of fertility preservation.The cryopreservation method is not optimized since only 10 % the sperms are expected tosurvive the treatment. The sperms are exposed to many risk factors such as oxidative stress,osmotic chock and ice crystallization. LÄS MER
4. Comparison between different freezing and thawing methods for human spermatozoa
Kandidat-uppsats, Institutionen för medicinsk biokemi och mikrobiologiSammanfattning : Preservation of cells and tissues by freezing at temperatures below 70°C has led to new possibilities for the storage of germ cells for fertility preservation. During the freezing process problems might occur, the greatest being ice crystallization which can cause membrane destruction and thus cell death. LÄS MER
