  1. 11. Optical properties in chalcogenide glasses and their temperaturedependence. : Literary survey and experiments.

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Matilda Karlsson; Saifallah Khaled Ali; Erik Lundqvist; Ask Löthman Ybo; Kalle Sigås; Oscar Törnquist; [2023]
    Keywords : Chalcogenide materials; Chalcogenide glass; Optical properties; Temperature dependence;

    Abstract : This study aimed to investigate methods for determining the temperature dependence of the refractive index and absorption of IR-transparent materials through literary studies and experimental tests. Results from the experimental trials were hard to obtain due to the inherent difficulty of measuring optical properties and yielded only temperature trends of transmittance and reflectance.

  3. 12. Feasibility Study of X-ray Free Electron Lasers in Fourth Generation Storage Rings

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratoriet

    Author : Jordis Hansen; [2023]
    Keywords : XFEL; Storage Ring; Synchrotron Radiation; Physics and Astronomy;

    Abstract : This thesis studies the feasibility of a cavity based X-ray free electron laser in a fourth generation storage ring. The cavity design allows for modulation of the electron beam over several passes through the undulator. Simulations based on the PETRA IV facility are done to create the photon flux spectrum of a light pulse produced by an undulator. READ MORE

  4. 13. Is the Expression of Hemolysin Co-regulated Protein (Hcp) Associated with Serum Resistance in Aggregatibacter aphrophilus?

    University essay from Umeå universitet/Tandläkarutbildning

    Author : Clara Settlin; Selva Hot; [2023]
    Keywords : Aggregatibacter aphrophilus; hcp; T6SS; serum resistance;

    Abstract : Abstract  Aggregatibacter aphrophilus, a Gram negative bacterium, found in the oral cavity, causing cerebral abscesses and infective endocarditis, has been shown to be serum resistant in previous studies. Bacterial secretion systems are important for bacteria as they transfer virulence factors into other bacteria or host cells as an attack. A. READ MORE

  5. 14. 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

  6. 15. Optimizing sunlight distribution in agrivoltaic systems for the Swedish climate

    University essay from Uppsala universitet/Solcellsteknik

    Author : Amanda Daniels; [2022]
    Keywords : agrivoltaics; agri-PV; solar energy; PV; photovoltaics; agriculture; renewable energy; sketchup; solenergi; jordbruk; förnyelsebar energi;

    Abstract : Due to a rising land demand for the construction of large-scale PV-systems, there is increasing competition between energy and food production. A new emerging segment within the PV market called agrivoltaics is providing a contributing solution to this issue by co-using the land for both crop cultivation and PV energy. READ MORE
