6. Light-Metal Hydrides for Hydrogen Storage
Sammanfattning : Demands for zero greenhouse-gas emission vehicles have sharpened with today’s increased focus on global warming. Hydrogen storage is a key technology for the implementation of hydrogen powered vehicles. LÄS MER
7. Kinetic Energy Storage and Magnetic Bearings : for Vehicular Applications
Sammanfattning : One of the main challenges in order to make electric cars competitive with gas-powered cars is in the improvement of the electric power system. Although many of the energy sources currently used in electric vehicles have sufficientlyhigh specific energy, their applicability is limited due to low specific power. LÄS MER
8. First Principle Studies of Functional Materials : Spintronics, Hydrogen Storage and Cutting Tools
Sammanfattning : 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. LÄS MER
9. Oxygen Storage Chemistry of Nanoceria
Sammanfattning : The versatile redox chemistry of ceria (CeO2) originates from its Ce4f electron, which plays the key role in changing the oxidation state of Ce between +IV and +III. Ceria is, among other things, a material that can act as a powerful oxygen buffer with a high oxygen storage capacity (OSC). LÄS MER
10. Efficient Processing and Storage for Massive MIMO Digital Baseband
Sammanfattning : Driven by the increasing demands on data rate from applications, the wireless communication standard has for decades been evolving approximately at a pace of one generation per ten years. Following this trend, the ambitious plan to replace the current cellular mobile network standard (4G) with the next generation standard (5G) is going through the standardization phase and is getting close to its actual deployment.
