1. A study of optical and structural properties of spin-coated V2O3 thin films on sapphire substrates
University essay from Linköpings universitet/Institutionen för fysik, kemi och biologiAbstract : Many transition metal oxides exhibit a Metal-Insulator Transition (MIT). This is an interesting phenomenon where the material undergoes a structural phase transition, and the electronic charge is redistributed in the crystal lattice. READ MORE

4. Impingement Cooling: Heat Transfer Measurement by Liquid Crystal Thermography
University essay from Mekanisk värmeteori och strömningsläraAbstract : In modern gas turbines parts of combustion chamber and turbine section are under heavy heat load, for example, the rotor inlet temperature is far higher than the melting point of the rotor blade material. These high temperatures causes thermal stresses in the material, therefore it is very important to cool the components for safe operation and to achieve desired component life. READ MORE

5. VO2 films as active infrared shutters
University essay from Institutionen för fysik, kemi och biologiAbstract : An active optical shutter for infrared light (3-5 μm) has been designed, exploiting the phase transition in thermochromic vanadium dioxide (VO2). A spin coating processing route for VO2 films has been adapted to manufacture reproducible depositions onto sapphire (Al2O3) substrates. READ MORE
