1. 16. Characterization of core-shell oxide nanoparticles

   University essay from SLU/Department of Molecular Sciences

   Author : Eline Goossens; [2018]
   Keywords : magnetic core-shell nanoparticles; characterization; iron oxide; silica;

   Abstract : The growing amount of applications of nanoparticles (NP) have led to concern for their possible harmful effect on human health and the leakage in the environment. Characterization and quantification of the content of NPs are of prime importance, especially methods to relate size, composition and morphology of the particles with the possibility of their detection and quantification.

3. 17. Investigation of Bismuth Iodine as Light Absorbing Materials for Solar Cell Applications: From Synthesis to XPS Characterisation

   University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

   Author : Jonatan Fast; [2017]
   Keywords : Bismuth; Iodine; Light absorbing; Light absorbing materials; Solar; solar cell; Synthesis; XPS; Characterisation; synchrotron; energy; x-ray photoelectron spectroscopy; perovskite;

   Abstract : During the last years perovskite materials have taken the photovoltaic community by storm, bringing promises of solar cells with efficiencies comparable to conventional silicon devices but at a lower price. However perovskite solar cells so far are facing two main obstacles, they are unstable in the presence of air, moisture and heat and they are usually toxic due to being based on lead-halide materials.

4. 18. Fluid-Structure Interaction; Numerical Modelling andExperimental Comparison

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Johan Lindgren; Hannes Karlsson; [2017]
   Keywords : Fluid-Structure Interaction FSI LS-DYNA mat_acoustic model; Technology and Engineering;

   Abstract : The purpose of this thesis is to investigate the effects of fluid-structure interaction on a submerged oscillating structure. It is to be determined whether it is possible to model such effects with acoustic fluid elements in LS-DYNA using Mat\_Acoustic. READ MORE

5. 19. Development and simulation of an active target detector with GEM foil readout

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

   Author : Elisabeth Rickert; [2017]
   Keywords : Physics and Astronomy;

   Abstract : At CERN, radioactive ion beams with energies of up to 10 MeV/u can be pro- duced by a newly commissioned post-accelerator, HIE-ISOLDE, which expands the possibilities for nuclear reaction studies. To investigate the collision properties of the ion beam with a target, an active gas–target detector is under development by the Reactions Group at the Nuclear Physics Division in Lund. READ MORE

6. 20. Interfaces in complex InAs-GaSb heterostructured nanowires - A transmission electron microscopy study

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Louise Uhrgård Gren; [2017]
   Keywords : transmission electron microscope; TEM; aberration corrected S TEM; nanowires; core-shell nanowires; InAs-GaSb; advanced characterization; Technology and Engineering;

   Abstract : In this project epitaxially grown InAs-GaSb complex heterostructured nanowires have been characterized by means of aberration corrected TEM techniques and energy dispersive X-ray spectroscopy (EDX). The InAs-GaSb material is of interest due to its high charge carrier mobility, which has possible applications in electronic devices such as FETs. READ MORE
