  1. 1. Detection of Contaminants in Water Using Surface Enhanced Raman Spectroscopy

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Freja Hansson; [2021]
    Nyckelord :Raman; Surface-enhanced Raman Spectroscopy; nanoparticles; contaminants; plasmonics;

    Sammanfattning : Due to deteriorating water quality and the world’s increasing demand for clean water, the need for cheap, easy and portable techniques to characterize and quantify pollutants in waters is urgent. Hence, surface-enhanced Raman spectroscopy (SERS) have gained considerable attention in this field. LÄS MER

  3. 2. X-ray Photoelectron Spectroscopy on Clusters: From Water Clusters to Metal & Metal-Oxide Nanoparticles

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Emmanouil Tzomos; [2021]
    Nyckelord :Nanoscience; Nanoparticles; Clusters; Synchrotron Radiation; Water Particles; Silver Particles; Silver Oxides; Ethylene Epoxidation; Radiotherapy; PES; XPS; Lund University; FlexPES; MAX IV; Physics and Astronomy;

    Sammanfattning : In the present work, two experimental setups aimed at the production of (1) water clusters and (2) metal-oxide nanoparticles were assembled and commissioned. The experiments on the cluster/nanoparticle beams were set up and performed at the FlexPES beamline of the MAX-IV synchrotron facility. LÄS MER

  4. 3. Molecular linking towards direct plasmonic transparent solar cell

    Master-uppsats, Uppsala universitet/Institutionen för kemi - Ångström

    Författare :Thinh Nguyen Luong The; [2020]
    Nyckelord :pABA; plasmonic; plasmon; solar; cell; Ag; silver; self; assembly; citrate;

    Sammanfattning : Plasmonic materials have been studied extensively in the last decade for applications in photonics, solar energy utilization and catalysis. The introduction of molecular linker bridging metal particles and oxide semiconductor has been proven to prolong the lifetime of short-lived hot carriers and prevent issues from ohmic contact.

  5. 4. Do Nanoparticles Affect Neuronal Function? - Establishment of a Microelectrode-Based Assay

    Master-uppsats, Lunds universitet/Tillämpad biokemi

    Författare :Markus Nylander; [2020]
    Nyckelord :Microelectrode array; gold nanoparticles; silver nanoparticles; immunocytochemistry; scanning electron microscopy; human neural progenitor cells; human induced pluripotent stem cells; applied biochemistry; tillämpad biokemi; Biology and Life Sciences; Technology and Engineering;

    Sammanfattning : Nanomaterials are used extensively in industry and daily life but comparatively little is known about the possible health effects. Silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs) are two metal nanoparticles that have been intensively studied. LÄS MER

  7. 5. Optical Characterization of Lignin Nanoparticles

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Kristoffer Linder; [2020]
    Nyckelord :lignin; nanoparticles; nanoparticle; optical characterization; optical properties; surface plasmon resonance;

    Sammanfattning : Lignin is one of the main components of wood and plants that acts as a kind of glue providing mechanical strength. It is a main polymer component composed from three phenolic structures, i.e. p-hydroxyphenyl (H), guaiacyl (G) and syringyl (S) units. LÄS MER
