1. Hydrogen Absorption in Metal Hydrides : Transmission of light in relation to hydrogen concentration and site occupancy of ultrathin vanadium films
University essay from Uppsala universitet/Tillämpad kärnfysikAbstract : In this study the effect of hydrogenation on the optical properties in the wavelength range 400-1023 nm of an ultrathin iron-vanadium superlattice is investigated. Specifically, mea- surements of transmission are performed under different states of hydrogenation, along with measurements of absolute hydrogen concentration and hydrogen site occupancy. READ MORE

2. Correlating Photoconductivity with Photochromism in Oxygen-containing Rare-earth Metal Hydride Thin Films
University essay from Uppsala universitet/MaterialfysikAbstract : Scientists have recently discovered simultaneous photoconductivity and photochromism (i.e., optical switching upon light exposure) of oxygen-containing rare-earth metal hydrides (REMHO). A deep understanding of these extraordinary optical and electrical properties can open the door to advanced technological uses such as smart windows. READ MORE

3. Electric Transport of Rare-earth Metal Oxy-hydride Thin Films
University essay from Uppsala universitet/Materialfysik; Uppsala universitet/Tillämpad kärnfysikAbstract : In this project, I investigate the photoconductivenature of photochromic rare-earth metal oxy hydrides (REMHO). Such materials have received increasingscientific attention since they show a color-neutralphotochromic effect that can be applied, e.g., in smartwindows or chromogenic devices. READ MORE

4. Photoconductivity in rare earth metal-oxy-hydrides
University essay from Uppsala universitet/MaterialteoriAbstract : In this project the evolution of resistivity under light exposition in materials like rare earth metal-oxy-hydrides is studied. These materials observe a decrease of the resistance when exposed under the light of a 19,5 W power lamp, and slowly tend to return to their initial resistance. READ MORE

5. Preparation and characterization of a metal hydride electrode
University essay from Oorganisk kemiAbstract : Metal hydrides are used as anode material in nickel metal hydride batteries and are of particular interest because of the potential to be a part of energy systems completely involving renewable sources (e.g. solar power, wind power etc.). READ MORE
