2. 1. Hydrogen Storage Materials : Design, Catalysis, Thermodynamics, Structure and Optics

   Author : Carlos Moysés Graça Araújo; Rajeev Ahuja; Ole Martin Løvvik; Uppsala universitet; []
   Keywords : Materials science; Hydrogen-storage materials; Density functional theory; Molecular dynamics; Catalysis; Thermodynamics; Optics; Materialvetenskap;

   Abstract : 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.

4. 2. First Principle Studies of Functional Materials : Spintronics, Hydrogen Storage and Cutting Tools

   Author : Fredrik Silvearv; Ahuja Rajeev; Ali Zaoui; Uppsala universitet; []
   Keywords : spintronics; hydrogen storage; coating materials; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : The properties of functional materials have been studied with density functional theory. The first type of materials that have been investigated is the so called diluted magnetic semiconductors. It is a new class of materials that could offer enhanced functionality by making use of spin in addition to the charge of the electron. READ MORE

5. 3. Graphite oxides for preparation of graphene related materials : structure, chemical modification and hydrogen storage properties

   Author : Alexey Klechikov; Alexandr Talyzin; Tamás Szabó; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphite oxide; graphene oxide; hydrogen storage; nanomaterials; adsorption; surface area; pore volume; Materials Science; materialvetenskap;

   Abstract : Carbon materials have been studied for hydrogen storage for decades, but they showed too low capacity at ambient temperature compared to target values for practical applications. This thesis includes two parts. First one is fundamental study of graphite oxides (GO) structure and properties. READ MORE

6. 4. Atomistic Modelling of Materials for Clean Energy Applications : hydrogen generation, hydrogen storage, and Li-ion battery

   Author : Zhao Qian; Rajeev Ahuja; Börje Johansson; Antonio Ferreira da Silva; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Renewable energy; Materials science; Hydrogen production; Hydrogen storage; Li-ion battery; Density functional theory; SRA - Energy; SRA - Energi; SRA - E-Science SeRC ; SRA - E-vetenskap SeRC ;

   Abstract : In this thesis, a number of clean-energy materials for hydrogen generation, hydrogen storage, and Li-ion battery energy storage applications have been investigated through state-of-the-art density functional theory.As an alternative fuel, hydrogen has been regarded as one of the promising clean energies with the advantage of abundance (generated through water splitting) and pollution-free emission if used in fuel cell systems.
