  1. 1. Humidity dependent conductivity of air in HVDC applications and the role of surfaces

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Erik Svensson; [2023]
    Keywords : HVDC; humidity; air conductivity; thin films; HVDC; luftfuktighet; luftkonduktivitet; tunna filmer;

    Abstract : High Voltage Direct Current (HVDC) bushings are insulated devices designed to facilitate the safe passage of electric current across an earthed barrier. Understanding air conductivity is of utmost importance in the design of HVDC components, which is determined by ion density and ion mobility. READ MORE

  3. 2. Optical Studies of Cellulose-Based Materials for Spectral Design of Camouflage and Passive Cooling Applications

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Olivia Grönlund Falk; Felix Valentin; [2022]
    Keywords : Nanocellulose; optical properties; spectroscopy; ellipsometry; BRDF measurements; optical microscopy; reflectance; transmittance; absorptance; transflectance; spectral design; camouflage; passive radiative cooling;

    Abstract : In the past few years, studies regarding new bio-based materials have led to an increased attention in the nanoscale product of cellulose, called nanocellulose. This biodegradable and renewable material has interesting physical, optical and thermal properties. READ MORE

  4. 3. Green Coacervates for Pharma and Food

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Izabella Imets; Andreas Vallin; [2022]
    Keywords : MSc; coacervate; biosurfactant; biopolymer; SAXS; DLS; elliposometry; pharmaceutical technology; Technology and Engineering;

    Abstract : Anionic biosurfactant-cationic biopolymer systems were investigated to identify and characterize a coacervation window. The characterization of the systems was performed with dynamic light scattering, small angle x-ray scattering and in-situ ellipsometry. READ MORE

  5. 4. Adsorption of lysozyme on Silica Surfaces and Specific ion effects

    University essay from Lunds universitet/Kemiska institutionen

    Author : Guillem Onyos de Plandolit Ruiz; [2019]
    Keywords : Ellipsometry; mesoporous silica nanoparticles; surfaces; physical chemistry; fysikalisk kemi; Chemistry;

    Abstract : Biomedical application of nanoparticles is largely associated to their fate in biological media which, in fact, is related to their surface properties. Surface functionalitzation plays a key role in determining biodegradation, cytotoxicity and biodistribution through interactions which may be meditated by the macromolecules occurring in biological media.

  6. 5. Transparent conductive oxides deposited by magnetron sputtering: synthesis and characterization

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Mathias Axelsson; [2019]
    Keywords : TCO; AZO; solar cell; magnetron sputtering;

    Abstract : The thesis has dealt with transparent conducting oxide (TCO) materials, with a focus on Al:ZnO and with studies on Sn:In2O3 and ZnO. TCOs are a material group that is used for its properties of being conductive and at the same time transparent. READ MORE
