  1. 6. Water emissions from fuel cell-powered construction equipment : Quantifying liquid water and water vapor emissions for sustainable construction equipment

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Roni Bulut; Patric Söderberg; [2023]
    Keywords : PEM fuel cell; Simulink; Simscape; construction equipment; exhaust water; liquid water; vapor water; performance;

    Abstract : The construction sector is responsible for 20% of Greenhouse Gas (GHG) emissions, of whichdiesel-powered construction equipment are large contributors. Currently there are many ongoing Fuel Cell (FC) powered construction equipment projects as it is seen as an attractiveoption to power the futures zero-emission heavy-duty machines. READ MORE

  3. 7. Design of a modular small-scale PMMA/Air hybrid rocket research engine

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Gustaf von Platen; [2023]
    Keywords : hybrid rocket engine; PMMA combustion; rocket engine design; combustion diagnostics; rocket engine; regression rate; preliminary design definition; hybrid rocket engine simulation; gaseous oxidizer; transparent rocket engine;

    Abstract : Rocket propulsion using the hybrid-propellant scheme is a technology that offers much promise in applications where high-performance liquid rocket engines are deemed too complex and solid rocket motors are considered to lack performance or safety. However, despite extensive research, there is still a lack of knowledge in the theoretical aspects of hybrid rocketry, especially in the area of fuel-oxidizer mixing and fuel regression rate.

  4. 8. Fiberströ : det hållbara strömaterialet för framtidens djurproduktion

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Emil Nordqvist; [2022]
    Keywords : Fiberströ; strömaterial; gödselfiber; djurhållning; djurvälfärd;

    Abstract : De svenska lantbrukarna står inför många olika val då de gärna vill uppnå en bra djurvälfärd för sina djur samtidigt som de vill försöka köpa produkter för så låga kostnader som möjligt. Med högre kostnader för nödvändiga produkter som bland annat el, bränsle, foder och strömedel utmanas den svenska lantbrukaren att hitta nya vägar att driva sitt företag. READ MORE

  5. 9. Oligosaccharide Analysis - Assessment of the DNS Method and Specification of Glucans Processed with CGTase

    University essay from Lunds universitet/Bioteknik; Lunds universitet/Bioteknik (master)

    Author : Matilda Johansson; [2022]
    Keywords : CGTase; DNS; Chromatography; HPAEC; HPAE; Carbohydrate; Carbohydrates; Glucans; Cyclodextrin glycosyltransferase; Biotechnology; Bioteknik; Flory; Enza; Enzyme; Technology and Engineering;

    Abstract : In this study, the reagent 3,5-dinitrosalicylic acid (DNS) and high-performance anion exchange chromatography (HPAEC) were used for carbohydrate characterisation. It was revealed that the DNS reaction is not exclusive to reducing ends as commonly thought, but rather that the reagent reacts with other parts of the carbohydrate molecules as well. READ MORE

  6. 10. Validating results from the Molten Salt Reactor Experiment by use of turbulent CFD simulations : A study of a modified U-tube shell-and-tube primary heat exchanger and radiator with molten salts

    University essay from Luleå tekniska universitet/Rymdteknik

    Abstract : Background Nuclear reactors utilizing molten fuels rather than solid fuels show a massive advantage in energy yield, waste handling and safety features. The only successful reactor utilizing a molten fuel was called the ‘Molten Salt Reactor Experiment’ (MSRE), built and operated in the Oak Ridge national laboratory (ORNL) in Tennessee, U.S.A.
