1. Photoelectron Spectroscopy on Atoms, Molecules and Clusters : The Geometric and Electronic Structure Studied by Synchrotron Radiation and Lasers
Abstract : Atoms, molecules and clusters all constitute building blocks of macroscopic matter. Therefore, understanding the electronic and geometrical properties of such systems is the key to understanding the properties of solid state objects. READ MORE

2. Optical properties of novel semiconductor nanostructures
Abstract : Semiconductor nanostructures, such as one-dimensional nanowires (NWs) and zerodimensional quantum dots (QDs), have recently gained increasing interest due to their unique physical properties that are found attractive for a wide variety of applications ranging from gas sensing and spintronics to optoelectronics and photonics. Here, especially promising are nanostructures based on compound semiconductors, including ZnO, GaNP and GaAs/InAs. READ MORE

3. Thermodynamic and kinetic properties of Fe-Cr and TiC-ZrC alloys from Density Functional Theory
Abstract : 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. READ MORE

4. On error controlled atomistic-to-continuum modeling with application to graphene monolayers
Abstract : In order to consider virtual materials, i.e. materials that are not manufactured yet, it can be advantageous to model physical phenomena on a lower length scale than the macroscopic one. In such a case, homogenization (or coarse-graining) can be a useful tool. READ MORE

5. Control of Alloy Composition and Evaluation of Macro Inclusions during Alloy Making
Abstract : In order to obtain a good performance and predict the properties of alloys, it is necessary to control the contents of alloying elements and to evaluate a largest inclusion in the product. Thus, improved techniques for both control of alloy elements and evaluation of the large inclusion in products will enable us to provide better qualities of the final products. READ MORE
