  1. 1. Numerical Simulations of Resonant Tunnelling Diodes

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Love Sundström; Alexander Holmström Janeld; [2023]
    Keywords : Quantum mechanics; numerical methods; resonant tunnelling diode;

    Abstract : In this thesis, four different numerical techniques are implemented for the purpose of simulating resonant tunnelling diodes (RTDs). The chosen methods were: piecewise constant transfer matrix (TMM-C), piecewise linear transfer matrix (TMM-L), quantum transmitting boundary method (QTBM), and the Crank-Nicolson method (CN).

  3. 2. Extracellular vesicles (EVs):roles in cell proliferation and transcriptomic analysis of HUVEC receiving cancerderived EVs

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Benyapa Tangruksa; [2021]
    Keywords : ;

    Abstract :  Extracellular vesicles (EVs) are released by almost  all types of cells. EVs play an    important role in cell-to-cell communication by sending biomolecules such as mRNAs to    other cells via endocytosis. READ MORE

  4. 3. Structural Battery Electrolytes

    University essay from KTH/Fiber- och polymerteknologi

    Author : Pernilla Öberg; Amanda Halvarsson; Julia Rune; Max Bjerkensjö; [2021]
    Keywords : structural battery electrolytes; polymerization-induced phase separation; bicontinuous morphology; lithium-ion conductivity; thiol-ene chemistry; Strukturella batteri-elektrolyter; polymerisations-inducerad fasseparation; bikontinuerlig morfologi; litium-jon konduktivitet; tiol-en kemi;

    Abstract : Strukturella batterier är multifunktionella; de tillhandahåller lagring av elektrokemisk energi samtidigt som de bidrar med en lastbärande funktion. Tillsammans möjliggör detta att batteriet kan integreras i karossen hos ett elektriskt fordon eller apparat. READ MORE

  5. 4. Development of corrosion resistant coatings using natural biopolymer and pollen

    University essay from KTH/Materialvetenskap

    Author : Alessandro Armani; [2020]
    Keywords : ;

    Abstract : Corrosion is a mechanism that highly reduces the lifetime of metals in different environments, especially in water or moisture environment. The worldwide maintenance cost due to corrosion is estimated in billions of dollars per year, and actual solutions in terms of coating usually contains toxic or environmentally harmful species.

  6. 5. Fast retuning of superconducting radiofrequency accelerating cavities in the European Spallation Source linear accelerator.

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Sofia Johannesson; [2020]
    Keywords : Accelerator; retuning; ESS; Technology and Engineering;

    Abstract : The aim of the degree project is to continue the work of PhD student YuanShuai Qin on creating a fast retuning of the ESS accelerator lattice in the event of an accelerating cavity being offline. The main goal of the project was evaluating and improving the retuning routine created by YuanShuai Qin. READ MORE
