  1. 1. Optical properties of water absorbing textiles for camouflage

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Eveline Örtenberg; [2023]
    Nyckelord :Camouflage; SWIR; Water; Nanocellulose; CNF; Textiles;

    Sammanfattning : Background matching, a form of camouflage, involves species developing patterns and coloration that closely resemble their environment. Humans have utilized camouflage and background matching, particularly in military applications, to reduce detectable characteristics, known as signatures. LÄS MER

  3. 2. Core-Shell Superparamagnetic Iron Oxide Nanoclusters for Bioconjugation

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Ronak Kakadiya; [2022]
    Nyckelord :Nanoparticles; Nanoclusters; SPIONs; Microwave-assisted synthesis; Solvothermal; Core-Shell; Bioconjugation; Green Chemistry.; Nanopartiklar; Nanokluster; SPIONs; Mikrovågsassisterad syntes; Solvotermisk; Core-Shell; Biokonjugation; Grön kemi.;

    Sammanfattning : Nanoparticles (NPs) have been part of our daily lives whether we are aware of it ornot and are continuously shaping our world of tomorrow. They are employed in awide range of applications such as in sunscreens, breaking down microplastics inthe ocean and scaling down beyond Moore’s law. LÄS MER

  4. 3. Easy-to-clean properties in coatings for automotive applications

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

    Författare :Weyni Ghebreamlak; [2021]
    Nyckelord :Easy-to-clean surface; sol-gel; superhydrophobicity; superoleophobicity; nanoparticles; Lätt-att-rengöra yta ”Easy-to-clean” ; sol-gel; superhydrofobicitet; superoleofobicitet; nanopartiklar;

    Sammanfattning : En ”lätt-att-rengöra” yta definieras som en yta som stöter bort vatten och smuts. I detta projekt har klarlack med olika sammansättningar studerats i syfte att introducera egenskapen ”lätt-att-rengöra”. För att uppnå denna egenskap måste beläggningen vara superhydrofob och oleofob. LÄS MER

  5. 4. Method for interfacial energy determination of gold nanoparticles on solid surfaces

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

    Författare :Mikaela Petersson; [2020]
    Nyckelord :Nanoparticles; sintering; interfacial energies; Young s equation; contact angle; Au; Si; silica; Sapphire; Al2O3; SEM; AFM; TEM; FFT; Science General;

    Sammanfattning : The high surface-to-volume ratio of nanoparticles (NPs) makes them an interesting source for scientific research. How interfacial energies interplay between such a small structure and a solid bulk surface, are important because of the versatile applications NPs regard. LÄS MER

  7. 5. The thermal insulating effects of Quartzene® on painting systems

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Arwin Zendehrokh; Luis Mariscal; Martin Hunhammar; Ismail Yussuf Hassan; Albert Pettersson; [2020]
    Nyckelord :aerogel; quartzene; insulation; nanoparticles; paint; Transient plane source; TPS; thermal conductivity;

    Sammanfattning : The European Green Deal 2020 goals for reducing emissions are enforcing rules on the energy performance of buildings. Therefore thermally insulating materials used as coatings are researched to reduce the energy emissions of buildings. An essential field of interest are nanomaterials. LÄS MER
