  1. 1. Tillverkning av kalibrerstandard förämnesbestämning i kärnbränslen

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Materialteori

    Författare :Isak Lundell; Sven Ekman; [2023]
    Nyckelord :kärnbränsle; kärnkemi; ICPMS; atomkraft; fissionsprodukter; transuran; simulerat bränsle;

    Sammanfattning : The test production of a simulated nuclear fuel, possible to use as a calibration standard was donethru dissolving the preferred dopant-metals in a nitric-salt into weak acid. This solution wasmixed with dissolved uranium-salt to aimed concentration. This was precipitated by rising pHforming metallic-hydroxide. LÄS MER

  3. 2. Moving in the dark : Mathematics of complex pedestrian flows

    Magister-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Meghashyam Veluvali; [2023]
    Nyckelord :Mathematical modelling of pedestrian dynamics; stochastic systems; evacuation time; random walk method; parabolic equation; finite difference method;

    Sammanfattning : The field of mathematical modelling for pedestrian dynamics has attracted significant scientific attention, with various models proposed from perspectives such as kinetic theory, statistical mechanics, game theory and partial differential equations. Often such investigations are seen as being a part of a new branch of study in the domain of applied physics, called sociophysics. LÄS MER

  4. 3. 3D Printing of Magnesium- and Manganese-Based Metal-Organic Frameworks for Gas Separation Applications

    L3-uppsats, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Dhruva Deole; [2022]
    Nyckelord :3D Printing; Additive Manufacturing; Metal-Organic Frameworks; Carbon Capture; Gas Separation;

    Sammanfattning : Metal Organic Frameworks (MOFs) are a class of porous materials that are predominantly obtained as powders and have been investigated as a solid sorbent for gas separation or carbon capture applications from combustion exhaust gases. The manufacturing of products with MOFs to use them for real life applications is still a major problem. LÄS MER

  5. 4. Experimental pressure loss analysis in a mini tube for a fully developed turbulent airflow. : Mini channels of lengths 22.5 mm to 150 mm in length with a constant diameter of 1.5 mm

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Soumen Ghosh; [2022]
    Nyckelord :Experimental fluid mechanics; Pressure drop; friction factor; Internal flow; fully developed flow; turbulent flow; Fluid mechanics; Ideal gas; Moody s chart; Additive manufacturing; compressible flow; turbine blade cooling; mini channel;

    Sammanfattning : The cooling systems in a gas turbine are especially important as the turbine blades and vanes are exposed to extreme temperatures. The relatively cool air is extracted from the compressors and fed to the turbines to cool the turbine blades. LÄS MER

  7. 5. Aerotaxy-grown GaAs nanowires using Ga seed particles

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Eric Ceccarelli; [2021]
    Nyckelord :Aerotaxy; GaAs nanowires; epitaxy; self-catalized growth; self-seeded growth; Ga seeded GaAs nanowires; Ga seeded GaP nanowires; Technology and Engineering;

    Sammanfattning : Aerotaxy offers an alternative method for the manufacturing of semiconductor nanowires. Instead of seeding growth on an expensive substrate, aerosol seed particles act as the catalyst for the Vapor–Liquid–Solid growth in a hot flow through reactor. LÄS MER
