1. Elements of modeling nanoparticle growth: Surface thermodynamics and dispersive interactions
Sammanfattning : Metal nanoparticles have in recent decades been the subject of intense research owing to their wide range of size and shape-dependent properties, which makes them interesting candidates for a variety of applications. Gold nanorods represent a particularly intriguing type of particle due to their tunable plasmonic properties. LÄS MER
2. Adsorption of surface active elements on the iron (100) surface : A study based on ab initio calculations
Sammanfattning : In the present work, the structural, electronic properties, thermodynamic stability and adatom surface movements of oxygen and sulfur adsorption on the Fe surface were studied based on the ab initio method. Firstly, the oxygen adsorbed on the iron (100) surface is investigated at the three adsorption sites top, bridge and hollow sites, respectively. LÄS MER
3. Hydrogen Storage Materials : Design, Catalysis, Thermodynamics, Structure and Optics
Sammanfattning : Hydrogen is abundant, uniformly distributed throughout the Earth's surface and its oxidation product (water) is environmentally benign. Owing to these features, it is considered as an ideal synthetic fuel for a new world energetic matrix (renewable, secure and environmentally friendly) that could allow a sustainable future development.
