1. 16. Planetary boundary layer height measurements in a rural environment in southern Sweden - Relation to meteorological parameters and aerosol particle concentrations

   University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Ellen Carneheim; [2020]
   Keywords : Physics and Astronomy;

   Abstract : The aim of this project is to analyse planetary boundary layer height (BLH) measurements from the Hyltemossa research station and find their dependence on seasonality, time of day, and air temperature. Further, investigation was made into the correlation between mass concentration of particulate matter with equivalent diameter... READ MORE

3. 17. Modified lignin as replacement of carbon black in elastomers- For the development of sustainable tyre technology : The substitution of carbon black with modified lignin- Green tyre technology

   University essay from Karlstads universitet/Avdelningen för kemiteknik

   Author : Mostafa Ahmed Ismail; [2020]
   Keywords : lignin; tyre rubber; elastomeric materials; esterfication;

   Abstract : Due to its large flexibility, low-price, large availability, and properties lignin is seen as an important compound with a wide range of applications. The increasing demand of fossil-based rubber materials is causing a serious threat to the environment and it is contributing to plastic- and marine pollution, ozone depletion and carbon dioxide emission (CO2) [1,2].

4. 18. Growth of filamentous fungi in pure olive oil : a fundamental study for application to vegetable oil-derived waste streams

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Tahir Muhammad Nazir; [2020]
   Keywords : filamentous fungi; oleaginous fungi; Aspergillus oryzae; Neurospora intermedia; olive oil; fat; fungal biomass;

   Abstract : Vegetable oil is more difficult to degrade by microorganisms in comparison to carbohydrates and protein. Thus, it creates serious environmental and health concerns if oil-derived waste streams produced by restaurants and industries remain untreated. READ MORE

5. 19. Sensorless Induction Welding of Carbon Fiber Reinforced Plastic Components

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Johan Bladh; [2020]
   Keywords : Technology and Engineering;

   Abstract : In this work, a method to estimate the weld-zone temperature during induction welding of carbon fiber reinforced plastics (CFRP) is developed. Today several methods exist to measure, or in other ways ensure, the correct temperature in the weld. READ MORE

6. 20. Microwave Heat Treatment of Black Liquor for the Degradation of Hemicellulose

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Maja Rydgård; [2020]
   Keywords : lignin; biofuel; black liquor; heat treatment; microwave heating; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

   Abstract : The largest use of fossil petroleum is the production of fuels. Hence, finding sustainable alter-natives is an important step to reduce the emissions of greenhouse gases. One such alternative is to produce fuel from biomass, such as waste products from agriculture and the forest indus-try. READ MORE
