  1. 1. Mathematical Modeling and Simulation of Cryogenic Liquid Hydrogen Storage

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Gusten Zandler Andersson; [2023]
    Keywords : Modeling; Simulation; Liquid Hydrogen; Storage tank; Modelica; Chemical engineering; Technology and Engineering;

    Abstract : Liquid hydrogen is an attractive alternative to fossil fuels in the aviation industry, but storing it both before and during flights introduces many challenges pertaining to the cryogenic liquid conditions required. Having reliable models to predict the dynamical behavior inside the storage tank is therefore of great interest. READ MORE

  3. 2. Strain/Stress profile investigation of crystals mounted in an optical instrument via FEM simulation

    University essay from Lunds universitet/Industriell Produktion

    Author : Matheus Amarante Machado; [2023]
    Keywords : Modeling; Abaqus; Y2SiO5; Finite Element Modeling; Strain; Stress; Yttrium Orthosilicate.; Technology and Engineering;

    Abstract : Abstract This work is one of a series of related papers that were made in Lund University. They were done to analyze in a multi scalar way the Yttrium Orthosilicate crystals (YSO), analyzing the variation of material properties stemmed from the mounting, composition and other parameters in the optical properties of Yttrium Orthosilicate crystals.

  4. 3. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength

    University essay from KTH/Tillämpad fysik

    Author : Alexandros Bampis; [2023]
    Keywords : Nanophotonics; Quantum Dot Positioning; Photoluminescence Mapping; Scanning Microscope; Nanofotonik; Positionering av kvantprickar; Fotoluminescenskartläggning; Skanningsmikroskop;

    Abstract : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. READ MORE

  5. 4. Feasibility Study of Resistivity Measurement of Metal Surfaces to Address Potential Dislocations Caused by Surface Conditioning

    University essay from Uppsala universitet/FREIA

    Author : Mircea-George Coman; [2022]
    Keywords : ;

    Abstract : High electrical fields are needed inside the accelerating cavities of particle accelerators in order to accelerate the particles to higher energies in shorter distances. But high electrical fields will lead to electrical breakdowns. READ MORE
