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

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Anna Wagne; [2023]
   Keywords : Lignin; extraction; hydrophobicity; chemical engineering; Technology and Engineering;

   Abstract : 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. READ MORE

3. 17. Towards Affordable Sodium-Ion Batteries : Mechanochemical Synthesis and Electrochemical Assessment of Iron-Based Fluorophosphate Cathode Material

   University essay from KTH/Materialvetenskap

   Author : Ratna Juwita; [2023]
   Keywords : Sodium-ion batteries; electrical energy storage EES ; iron oxide; positive electrode; material characterization; electrochemical; discharge capacity.; Natriumjonbatterier; elektrisk energilagring EES ; järnoxid; positiv elektrod; materialkarakterisering; elektrokemisk; urladdningskapacitet;

   Abstract : An urgent transformation from fossil fuels to cleaner energy sources to combat climate change has led to the utilization of renewable energies like solar, wind, and tidal power. However, the intermittency of these sources hinders their wider implementation. To address this, large-scale electrical energy storage (EES) systems are needed. READ MORE

4. 18. A feasibility study of smart insoles with graphene coated resistive textile sensors.

   University essay from Mälardalens universitet/Akademin för innovation, design och teknik

   Author : Tewolde Neud; [2023]
   Keywords : Smart Insoles; Resitive textile sensors; Pressure-sensitive insoles; Graphene coating;

   Abstract : Pressure sensitive insoles are an emerging and promising technology that has always been interesting for gait and planar pressure related applications. This technology can be especially valuable for monitoring, movement, and rehabilitation purposes where the pressure sensing insoles could be utilized to assess for abnormalities in order to treat or prevent complications.

5. 19. Fabrication and characterization of GaAsxP1-x single junction solar cell on Si for III-V/Si tandem solar cell

   University essay from KTH/Tillämpad fysik

   Author : Elaheh Aghajafari; [2023]
   Keywords : III-V semiconductor; GaAsxP1-x heteroeputaxy; hydride vapor phase epitaxy; III-V Si solar cell; III-V halvledare; GaAsxP1-x epitaxiallager; hydridångfasepitaxi; III-V Si solcell;

   Abstract : Silicon based solar cells have been used as photovoltaic devices for decades due to reasonable cost and environment- friendly nature of silicon. But the conversion efficiency of silicon solar cell is limited; for instance, the maximum conversion efficiency of a crystalline silicon solar cell available in the market developed by Kaneka Corporation is 26 % [1].

6. 20. Electrochemical Characterisation of LiFePO4-Coated Carbon Fibres: A Comparative Electrochemical Analysis of Three Coating Methods

   University essay from KTH/Tillämpad elektrokemi

   Author : Julia Szecsödy; [2023]
   Keywords : Structural battery composite; Carbon fibres; Lithium-ion battery; Electrophoretic deposition; Spray coating; Powder impregnation; Strukturella batteri kompositer; Kolfiber; Litiumjon batteri; Elektroforetisk beläggning; Sprutbeläggning; Pulverimpregnering;

   Abstract : Kolfiber CF kan användas som positiv elektrod i strukturella batterier om de beläggs med ett aktivt material, såsom litiumjärnfosfat LFP. Fördelen med att använda kolfibrer som elektroder är att de samtidigt kan bära mekanisk belastning och lagra elektrisk energi. Det finns flera tekniker för att belägga kolfibrerna. READ MORE
