  1. 1. Colloidal self-assembly of anisotropic gold nanoparticles

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

    Författare :Samuel Emilsson; [2020]
    Nyckelord :Self-assembly; Gold nanoparticle; Anisotropic; Nanobipyramid; Surface plasmon resonance; Självsammansättningar; Guldnanopartiklar; Anisotrop; Nanobipyramider; Ytplasmonresonans;

    Sammanfattning : The colloidal self-assembly of plasmonic gold nanoparticles (AuNPs) is of interest to utilize the plasmonic coupling effects that arise between nanoparticles. The enhanced properties of anisotropic AuNPs make them particularly attractive in self-assemblies. LÄS MER

  3. 2. Enhancing the degradation rate of microplastics and organizing a study visit about sustainability

    Uppsats för yrkesexamina på avancerad nivå, KTH/Lärande

    Författare :Marianne Al-Ghorabi; [2020]
    Nyckelord :Accommodation; assimilation; Fenton reaction; microplastics; polypropylene; polystyrene; proximal development zone; study visit; visible light photocatalysis; zinc oxide nanorods; Ackommodation; assimilation; den proximala utvecklingszonen; Fenton reaktion; fotokatalys med synligt ljus; mikroplast; polypropalen; polystyren; studiebesök; zinkoxid nanorör.;

    Sammanfattning : Microplastics take hundreds to thousands of years to degrade in nature, and pose a threat to the environment. A photocatalytical degradation method have been developed to take advantage of solar light to degrade microplastics, however it takes several months to degrade microplastics with the process.

  4. 3. Cu2O/TiO2 Nanorod Heterojunctions: Synthesis, Characterization and Applications as Solar Cells on the Nanoscale

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Edward Dellamary; [2020]
    Nyckelord :;

    Sammanfattning : Novel solar cells are being synthesized from sustainable, non-toxic, and economic materials. All metal oxide semiconductors are one such class of these materials. LÄS MER

  5. 4. Degradation of Microplastic Residuals in Water by Visible Light Photocatalysis

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Tajkia Syeed Tofa; [2018]
    Nyckelord :Microplastics; Low density Polyethylene LDPE ; Heterogeneous photocatalytic degradation; Zinc oxide nanorods; Visible light.;

    Sammanfattning : Microplastic (MP) pollution has recently been recognized as a threat to the biosphere including humans due to its widespread distribution, persistent nature and infinitesimal size. This study focused on the solid phase degradation of microplastic residues (particularly low density polyethylene, LDPE) in water through heterogeneous photocatalysis process by designed photocatalysts of zinc oxide nanorods (ZnO NRs) and platinum nanoparticles deposited on zincoxide nanorods (Pt NPs-ZnO NRs) under visible light irradiation.

  7. 5. Biofunctionalization of a Fiber Optics-Based LSPR Sensor

    Master-uppsats, Linköpings universitet/Molekylär fysik

    Författare :Karl Schenström; [2016]
    Nyckelord :Localized surface plasmon resonance; LSPR; nanoparticles; AuNP; AuNR; biosensor; refractive index; spectrophotometry; IgG; insulin; avidin;

    Sammanfattning : When exposed to light, metal nanoparticles exhibit a phenomenon known as LSPR, Localized Surface Plasmon Resonance. The wavelengths at which LSPR occurs is very dependent on the refractive index of the surrounding medium. LÄS MER
