  1. 1. Study of Surface Pre-treatments for AuSi Wafer-Level Eutectic Bonding : An investigation of the impact of different native oxide etching methods and storage times before AuSi eutectic bonding

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Gabriel Boström; [2022]
    Nyckelord :Eutectic gold-silicon bonding; Native oxide growth; Oxide etching; Spectroscopic ellipsometry; Bond Strength; Water contact angle.; Eutektisk guld-kisel-bondning; Nativoxid-tillväxt; Oxidets; Spectroskopisk ellipsometri; Bondstyrka; Vattenkontaktvinkel.;

    Sammanfattning : Wafer bonding is important in microelectromechanical systems (MEMS) manufacturing, enabling wafer-level encapsulation and packaging. In this project, different pre-treatments of the polycrystalline silicon surface for eutectic gold-silicon (AuSi) bonding were studied with respect to the resulting bond strength. LÄS MER

  3. 2. Techno economic assessment of CCUS for a biogas facility in Sweden : Evaluating the economic feasibility for three CCUS concepts

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Tobias Johansson; Markus Knutsson; [2022]
    Nyckelord :CCS; CCU; CCUS; Biogas; Biologic methanation; Negative emissions; TEA; Techno economic assessment.;

    Sammanfattning : Many countries strengthen their commitments to reduce greenhouse gas emissions to limit climate change and meet the Paris Agreement (Masson-Delmotte et al., 2019). Commitments include achieving net-zero emissions or in some cases even negative emissions (Government offices of Sweden, 2020a; United Nations, 2021a). LÄS MER

  4. 3. Hydrogen Absorption in Metal Hydrides : Transmission of light in relation to hydrogen concentration and site occupancy of ultrathin vanadium films

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :David Sörme; [2022]
    Nyckelord :metal hydrides; iron-vanadium superlattice; hydrogen; hydrogen site occupancy; hydrogen concentrationm; hydrogen storage;

    Sammanfattning : In this study the effect of hydrogenation on the optical properties in the wavelength range 400-1023 nm of an ultrathin iron-vanadium superlattice is investigated. Specifically, mea- surements of transmission are performed under different states of hydrogenation, along with measurements of absolute hydrogen concentration and hydrogen site occupancy. LÄS MER

  5. 4. Finita elementsimuleringar för Norvik hamn

    Master-uppsats, KTH/Hållbara byggnader

    Författare :Mauritz Djursén; [2022]
    Nyckelord :;

    Sammanfattning : Norvik hamn är en nybyggd ro-ro- och containerhamn placerad på de bästa läget i Östersjön. Norvikhamn ligger endast några kilometer från Nynäshamn och med hjälp av korta infarter och effektivatransportförbindelser ger den direkt tillgång till hela stockholmsområdet. Hamnen är utrustad med enså kallad markstensbeläggning. LÄS MER

  7. 5. Dealing With Speckle Noise in Deep Neural Network Segmentation of Medical Ultrasound Images

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)
