1. 1. Photo-physical properties of up-converting NaYF4:Yb-Er,Yb-Mn nanocrystals

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Hongjian Wu; [2022]
   Nyckelord :Appled Physics; Tillämpad fysik;

   Sammanfattning : Rare earth-doped upconversion nanoparticles can emit light with various wavelength from ultraviolet to infrared when excited by near-infrared light. The superior properties including long luminescence lifetime, narrow emission spectra, low toxicity and high chemical stability makes it a promising optical material in bioimaging and other applications.

4. 3. Structural integrity of highly ionized peptides

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Molekyl- och kondenserade materiens fysik

   Författare :Ibrahim Eliah Dawod; [2019]
   Nyckelord :X-ray free-electron laser; X-ray imaging; XFEL; Computer simulations; Radiation damage; Ab-initio molecular dynamics; DFT; TDDFT; Excited states; Femtosecond; Bioimaging;

   Sammanfattning : In order to understand the behaviour and function of proteins, their three dimensional structure needs to be known. Determination of macro-molecules’ structures is done using X-ray diffraction or electron microscopy, where the resulting diffraction pattern is used for molecular reconstruction. LÄS MER
