1. 16. How to Rise from Ashes : A Comprehensive Guide to Finally Understand Canonical Quantization and Build Quantum Mechanics from Scratch

   University essay from Uppsala universitet/Materialteori; Uppsala universitet/Avdelningen för teoretisk filosofi

   Author : Karl Herlin; [2022]
   Keywords : Quantum mechanics; History of quantum mechanics; Canonical Quantization; double-slit experiment; The Photoelectric Effect; Compton Scattering; Matter Waves; Bohr’s Atomic Model; Old Quantum Theory; Heisenberg-Born-Jordan Matrix Mechanics; Schrodinger’s Quantum Wave Mechanics; equations of motion;

   Abstract : In this review essay, we account for the historical development of canonical quantization. By a detailed review of The Ultraviolet Catastrophe, The Photoelectric Effect, Compton Scattering, Matter Waves and Bohr's Atomic Model we learn about Old Quantum Theory. READ MORE

3. 17. Unspecific interactions in different batch variations of agarose based base matrices at different NaCl concentrations.

   University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Author : Kejvan Ghofranpanah; [2022]
   Keywords : Lysozyme; hydrophobicity; size exclusion chromatography; NaCl concentrations; isocratic elution; Lysozym; hydrofobicitet; size exclusion chromatography; NaCl-koncentrationer; isokratisk eluering;

   Abstract : Size exclusion chromatography (SEC) separates molecules based on their actual size rather than their molecular weight. This indicates that the smaller a molecule is, the longer it will be held in the column since it can penetrate the pores more effectively than a bigger molecule, resulting in a longer retention time, whereas the larger molecule has a shorter retention time.

4. 18. Identification of photodegradation products from commonenvironmental pollutants using gas chromatography coupled withhigh resolution mass spectrometry

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Vanessa Cajes; [2022]
   Keywords : Photodegradation; Organic contaminants; High resolution mass spectrometry; Identification; Spectral library;

   Abstract : Photodegradation is a major degradation mechanism for many environmental contaminants, both in indoor environments as well as in outdoor environments, and many of the contaminants are persistent and toxic. However, there is a lack of knowledge about the exact degradation process for many of them. READ MORE

5. 19. Design of LED setup for measuring tandem solar cell subcell J-V behaviour

   University essay from

   Author : Kristina Bergström; Mohammed Nour Kamalmaz; Erik Lindvall; [2022]
   Keywords : Tandem solar cell; LED; background light; bias; arduino; processing; subcell;

   Abstract : The need to accurately measure multi-junction (MJ) tandem solar cells' subcell current-voltage characteristics is increasing due to the vital information they provide about the efficiency, stability, and longevity of the cells. These measurements are rather difficult compared to their counterpart single-layer solar cell measurements. READ MORE

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

   University essay from KTH/Tillämpad fysik

   Author : Hongjian Wu; [2022]
   Keywords : Appled Physics; Tillämpad fysik;

   Abstract : 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.
