4. Composition, properties and surface structure of tribochemically deposited coatings
University essay from Tillämpad materialvetenskapAbstract : Five tribochemically deposited coatings on honed cast iron cylinder liner segments has been studied with respect to surface properties, material composition, coating thickness, hardness and friction. Methods like Light Optical Microscopy (LOM), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), 3D topography using white light interferometry (VSI) and Electron Spectroscopy for Chemical Analysis (ESCA) were used to study the surface, coating thickness and material composition.

5. Near infrared and visible optical properties in electrochromic crystalline tungsten oxide thin films on ITO
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : In this project I have studied the optical properties of electrochromic crystalline tungsten oxide, WO3. The practical application could be for a window for desalination of sea water which requires a high absorption coefficient A(λ) for near infrared radiation (NIR), while at the same time a high transmittance T(λ) in the visible spectral range.
