  1. 11. Magnetic Ionic Liquids in Solutions and Emulsions

    University essay from KTH/Materialvetenskap

    Author : Simon Bruno; [2022]
    Keywords : ionic liquids; microemulsion; magnetic response; surfactant; co-surfactant; imidazolium cation; polarity; chain length effect; joniska vätskor; mikroemulsion; magnetisk respons; surfaktant; co-surfaktant; imidazoliumkatjon; polaritet; kedjelängdseffekt;

    Abstract : This research thesis reports experimental work done to design a stable magneticmicroemulsion of ionic liquid in 2-ethylhexyl laurate with the help of an ionic surfactant andan alcohol co-surfactant. The ionic liquids tested were based on a 1,3-dialkylimidazoliumcation with different alkyl chain lengths and a tetrachloroferrate anion ([FeCl4]+) to ensure theemulsion is sensitive to applied magnetic fields.

  3. 12. Improvement of Pt-based catalyst supported on CeZrO2 used for the high-temperature water-gas shift reaction

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Milda Grikainyte; [2022]
    Keywords : Water-gas shift; catalyst; chemical engineering; Chemistry;

    Abstract : The iron-chromium (Fe/Cr) catalyst is used for high-temperature water-gas shift (HT WGS) reaction. A major concern using the Fe/Cr catalyst is that it contains hexavalent chromium (Cr+6) which is a potent carcinogen causing health and environmental issues. READ MORE

  4. 13. BVOC emission variability for Norway spruce (Picea abies) in Hyltemossa, Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alexandra Arnsteg; [2022]
    Keywords : BVOC; isoprene; monoterpenes; induced emission; light dependency; temperature; Norway spruce.; Earth and Environmental Sciences;

    Abstract : Biogenic volatile organic compounds (BVOC) are known as hydrocarbons emitted into the atmosphere from the biosphere. They have physiological and ecological functions such as communication within the plant and plant – plant, protection against environmental stress factors and defense against herbivores attack.

  5. 14. Analysis of Aircraft Emissions Based on Flight Trajectory : ATR 72-500 trajectory and emission study

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Gustav Forsberg; Carl-Michael Sundberg; [2022]
    Keywords : trajectory; emissions; Boeing Fuel Flow;

    Abstract : Emissions related to aviation have during the last decades become an important topic of discussion. Besides carbon dioxide ($CO_2$) which is the major pollutant from air travel, other gas emissions such as hydrocarbons ($HC$), nitrogen oxides ($NO_x$), carbon monoxide ($CO$) and sulfur oxides ($SO_x$) also need to be investigated.

  6. 15. Converting an Automobile Engine to an Aircraft Engine

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Gabriel Kronberg; [2022]
    Keywords : Piston Engine; Tiny Friendly Giant; Aviation Emissions; Engine Cooling; GREET; BFFM2; Sustainable Aviation Fuel; Engine Conversion; Emission Estimation; Trade Study; Kolvmotor; Tiny Friendly Giant; Flygutsläpp; Motorkylning; GREET; BFFM2; Hållbart flygbränsle; Motorkonvertering; Utsläppsupskattning; Paramterstudie;

    Abstract : This project evaluates the opportunity to convert a three-cylinder automobile piston engine (the Tiny Friendly Giant) to an aircraft engine from an environmental and practical point of view. The problem of increased emissions from aviation calls for technical and socioeconomic solutions, which is the reason why this report is written. READ MORE
