  1. 1. Real- and Quasi-Atomic Layer Etching for Ultra-High Resolution Patterning

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

    Författare :Yoana Ilarionova; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : An attempt was made at developing atomic layer etching from a cyclic etching process in an ICP-RIE tool. During the process OES was used for contamination monitoring and estimation of the relative amount of Cl2 left in the chamber during the etch step of cyclic etching processes. LÄS MER

  2. 2. Design, Analysis and Performance Evaluation of Indirect Solar Dryer

    Magister-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Tandin Jamtsho; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Food production is a critical component of global livelihoods and economic revenue. However, storing harvested food presents challenges in minimizing post-harvest losses. Among various methods, food drying has emerged as a popular technique for preserving food during off-seasons. LÄS MER

  4. 4. Analysis and Measurement of Key Performance Indicators for MIMO Antennas

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Ossian Kynman; [2023]
    Nyckelord :MIMO; Diversity Gain; Capacity; Correlation; Fading;

    Sammanfattning : Multiple-in multiple-out (MIMO) is a wireless communication technique where antenna arrays, at the receiver and transmitter, utilize signal multipath propagation to increase data throughput capacity. The unique benefits MIMO provides have over the last 20 years led to the steady increase in usage in both Wi-Fi and mobile networks. LÄS MER

  5. 5. Modelling Gas Flow Behaviour in Gas Atomizer

    Master-uppsats, KTH/Materialvetenskap

    Författare :Aravind Senan Vasanthasenan Reji; [2022]
    Nyckelord :Gas atomization; Nozzle; Velocity; Static pressure; Discrete phase model; Gasatomisering; Munstycke; Hastighet; Statiskt tryck; Diskret fasmodell;

    Sammanfattning : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.
