2. Chemical modification of regenerated-cellulose films with determined patterns and different regeneration mediums to achieve superhydrophobic properties
University essay from Mittuniversitetet/Institutionen för kemiteknikAbstract : In our modern society there is a need to find a material that is biodegradable to reduce the use of plastic for a greener society. By means of superhydrophobic surfaces there is a possibility to replace plastic with cellulose and use Alkyl Ketene Dimer (AKD) as a sizing agent to make the surface hydrophobic. READ MORE

4. Analysis of short chain fatty acids in faecal samples : development and validation of a new method
University essay from SLU/Dept. of Food ScienceAbstract : Short chain fatty acids (SCFA) are produced by the gut microflora following the intake of complex carbohydrates and have been suggested as a contributor for some of the health benefits associated with dietary fibre (DF) intake. For further research of the mechanisms and effects of SCFA, reliable and accurate methods for analysis of SCFA in different biological samples are needed. READ MORE

5. Development of optimized Raman Spectroscopy setup for species detection in flames
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/FörbränningsfysikAbstract : A multi-pass Raman spectroscopy setup, consisting of a measuring cell built as a cavity, using two concave circular mirrors, has been constructed and optimized. As the light reflects between the mirrors, the Stokes Raman signal is enhanced with every pass through the cavity. READ MORE
