1. 1. Optical Communication using Nanowires and Molecular Memory Systems

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

   Författare :Thomas Kjellberg Jensen; [2024]
   Nyckelord :neuromorphic computing; nanowire; molecular dye; DASA photoswitch; OBIC; Physics and Astronomy;

   Sammanfattning : Neuromorphic computational networks, inspired by biological neural networks, provide a possible way of lowering computational energy cost, while at the same time allowing for much more sophisticated devices capable of real-time inferences and learning. Since simulating artificial neural networks on conventional computers is particularly inefficient, the development of neuromorphic devices is strongly motivated as the reliance on AI-models increases.

3. 2. Recovery of Dialcohol Cellulose using Micro- and Ultrafiltration Processes

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Lina Näslund; Gabriella Petersson; [2023]
   Nyckelord :Membrane filtration; Ultrafiltration; Microfiltration; Dialcohol cellulose; DAC; Bioplastics; Chemical engineering; Process design; Technology and Engineering;

   Sammanfattning : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. LÄS MER

4. 3. Concentration of Proteins and Decrease of Salt Content in a Hydrolyzed Fermentation Broth Using Membrane Filtration

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Linnea Sjökvist; [2023]
   Nyckelord :Membrane filtration; ultrafiltration; PHA; polyhydroxyalkanoates; chemical engineering; Technology and Engineering;

   Sammanfattning : Membrane filtration was used to concentrate proteins and decrease the salt concentration in a hydrolyzed fermentation broth. The broth was a by-product from the bacterial production and extraction of polyhydroxyalkanoates (PHA), that can be used to produce biobased plastics. LÄS MER

5. 4. Continuous Fibre Reinforcements in Injection Moulded Composites

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Erik Björkqvist; [2023]
   Nyckelord :Injection moulding; Plastics; Thermoplastics; Fibre Reinforcement; FEM; Formsprutning; Plast; Termoplast; Fiberarmering; FEM;

   Sammanfattning : The use of continuously reinforced thermoplastics have increased in recent years andoffer some significant advantages over their thermoset counterparts. The utilizationof these materials is however still limited due to the labour intensive processingand manufacturing. LÄS MER

7. 5. Investigation of Milled Wood Lignin Extraction Using Enzymatic Hydrolysis for Application in Hydrophobic Barriers in the Food Packaging Industry

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Anna Wagne; [2023]
   Nyckelord :Lignin; extraction; hydrophobicity; chemical engineering; Technology and Engineering;

   Sammanfattning : The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. LÄS MER
