16. Beyond Perturbation: Modeling Anharmonicity in Materials
Sammanfattning : The vibrational motion of atoms is essential for understanding condensed matter systems. It directly influences numerous thermodynamic properties with significant technological implications. LÄS MER
17. Thermodynamic and kinetic properties of Fe-Cr and TiC-ZrC alloys from Density Functional Theory
Sammanfattning : The complete and accurate thermodynamic and kinetic description of any systemis crucialfor understanding and predicting its properties. A particular interest is in systemsthat are used for some practical applications and have to be constantly improved usingmodification of their composition and structure. LÄS MER
18. Thermal Radiation from Co-evaporated Cu(In,Ga)Se2 : End point detection and process control
Sammanfattning : The use of solar cells for energy production has indeed a bright future. Reduction of cost for fabrication along with increased efficiency are key features for a market boom, both achieved as a result of increased knowledge of the technology. LÄS MER
19. Local variability in chemical and physical properties of spruce wood fibers
Sammanfattning : Wood is well known to be a heterogeneous native materialwith large variations in its composite properties, includingvariations whose origins have not yet been completelyidentified. Traditionally, the macroscopic variations in woodhave received the most attention; for example, the variation indensity from the pith to the bark in trees. LÄS MER
20. Energy Relevant Materials: Investigations Based on First Principles
Sammanfattning : Energy production, storage and efficient usage are all crucial factors for environmentally sound and sustainable future technologies. One important question concerns the refrigeration industry, where the energy efficiency of the presently used technologies is at best 40% of the theoretical Carnot limit. LÄS MER
