  1. 1. Acoustic Focusing of Lysozyme Crystals

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Måns Junestrand; [2023]
    Nyckelord :Protein Crystals; Lysozyme Crystals; Ultrasound; Acoustic Focusing; SFX; Biomedical Physics; Proteinkristaller; Ultraljud; Lysozymkristaller; Akustisk fokusering; SFX; Biomedicinsk fysik;

    Sammanfattning : Acoustic focusing of microscale protein crystals with acoustophoresis technology could reduce clogs during experiments with the scientific technique serial femtosecond x-ray crystallography (SFX). SFX determines molecular structures of proteins, these structures are valuable in drug discovery and fundamental biomedical research. LÄS MER

  3. 2. Measuring Acoustic Mobility of Particles by Particle Tracking Velocimetry

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Alexander Edthofer; [2022]
    Nyckelord :acoustophoresis; microfluidics; polystyrene; cells; particle tracking velocimetry; Technology and Engineering;

    Sammanfattning : Acoustophoresis is a method to manipulate and move cells or particles suspended in a medium using acoustic waves. The speed of the acoustophoretic motion depends on the cells' acoustic mobility, i.e. their size, density and compressibility relative to the medium. LÄS MER

  4. 3. Sonar Sea : The acoustic experience of the Baltic Sea dynamics

    Master-uppsats, Konstfack/Inredningsarkitektur & Möbeldesign

    Författare :Elin Stampe; [2021]
    Nyckelord :spatial design; the Baltic Sea; water; dynamics; atmosphere; sound; acoustic ecology; field recordings; nature; sensory experience; flow; performative space; art; science; companion species; installation; rumslig gestaltning; Östersjön; vatten; dynamik; atmosfär; ljud; akustisk ekologi; natur; sinnesupplevelse; konst; vetenskap; installation;

    Sammanfattning : This thesis project aims to discuss the conditions and importance of water as a dynamic body in our environment, as water is affecting life on Earth on all levels. By focusing on the Baltic Sea, a sensitive body of water, I am exploring the acoustic characters of the sea dynamics through sound recordings at three bays in the Stockholm Archipelago. LÄS MER

  5. 4. An indicative case-control study of noise perception due to environmental noise sources

    Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWL

    Författare :Marcus Johansson ; [2020]
    Nyckelord :Noise perception; Psychoacoustics; Environmental noise; Bullerpåverkan; Psykoakustik; Samhällsbuller;

    Sammanfattning : The subject of the thesis was proposed by the acoustic consultancy firm Brekke & Strand, which is of relevance for their additional understanding and development of services and contribution to robust solutions. The aim with this thesis is to give indicative results and to dig deeper into the relation between environmental noise and the perception of the same, specially focusing on construction related noise but also permanent noise sources that originates from infrastructure.

  7. 5. Micromachining of microfluidicsystems using a nanosecond laser : Process optimization and application

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Mikrosystemteknik

    Författare :Per Söderbäck; [2019]
    Nyckelord :Acoustophoresis; Acoustofluidics; Laser micromachining; Microfabrication; Particle manipulation; Ultrasound;

    Sammanfattning : Microfluidics is a field of research that enables the manipulation of fluids in the submillimetre length scale. The technology allows the development of lab-on-a-chip devices, which are miniaturized systems for chemical and biological analysis. LÄS MER
