  1. 1. Frontier materials at the air-liquid interface: Self-assembly of green ionic liquids

    Kandidat-uppsats, KTH/Yt- och korrosionsvetenskap

    Författare :Ulrika Karlson; Morgan Ölander; Fernando Zevallos; [2021]
    Nyckelord :Ionic liquids; Green chemistry; X-ray reflectivity; AIR-liquid interface; Self assembly; Jonvätskor; Grön kemi; Självorganisation;

    Sammanfattning : The interfacial structuring of three non-halogenated ionic liquids was examined at the air-liquid interface for both dry and humid condition by analysis of X-ray reflectometry data using a slab model approach. The aim was to investigate the effect of humidity on the air-liquid interface. LÄS MER

  3. 2. Air Liquid Interface System

    Magister-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Max Attergren; Martin Lindwall; [2021]
    Nyckelord :ALI-System; Design; Production; ALI-System; Design; Produktion;

    Sammanfattning : The ALI-System is used to determine the toxicity of airborne nanoparticles to the human lungs. The following report seeks to describe the process of preparing an ALI-system built in a laboratory, for use outdoor. The project also involves preparing the existing ALI-system for manufacturing.

  4. 3. Exposure of zinc oxide nanoparticles on lung epithelium: A comparison between submerged and air-liquid interface cultures

    Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologi

    Författare :Julia Dobric; [2019]
    Nyckelord :lung toxicology; nanotoxicology; aerosol; air-liquid interface; ALI; NACIVT; nanoparticles; zinc oxide; Biology and Life Sciences;

    Sammanfattning : Zinc oxide nanoparticles (ZnO NPs) are often used in sunscreen and other cosmetic products with sun protection. They are also candidate to be used for various biological applications such as drug delivery, or in material science in for example solar cells. LÄS MER

  5. 4. Rheological changes at the air-liquid interface and examining different kind of magnetic needles

    Master-uppsats, Karlstads universitet/Avdelningen för kemiteknik

    Författare :Fredrik Anderson; [2015]
    Nyckelord :Interfacial Shear Rheometer; rheometry; magentic needles; oscillation; surface chemistry; modulus; elastic; viscous; viscoelasticity; Reologi; elasticitetsmodul; oscillering; magnetiska nålar; viskositet; viskoelasticitet;

    Sammanfattning : The main objective in this work was to learn how the instrument, the Interfacial Shear Rheometer (ISR400), worked and to investigate how the rheological properties, storage modulus (elasticity), G' and loss modulus (viscous), G'', changes when the surface pressure at the air-liquid interphase changes. The second objective were to examine the different kind of magnetic needles used in the experiments and to conclude which type of needle is best for its specific field of analysis. LÄS MER
