1. Life strategies for substrate assimilation by freshwater bacterioplankton
Abstract : The availability of substrates is one of the most important environmental constraints on the diversity and functioning of microorganisms. Substrate quantity and quality as well as the metabolic features of heterotrophic microorganisms determine the efficiency, speed and type of transformation that can occur in nature. READ MORE

2. Reduction of Substrate Noise in Mixed-Signal Circuits
Abstract : In many consumer products, e.g., cellular phones and handheld computers, both digital and analog circuits are required. Nowadays, it is possible to implement a large subsystem or even a complete system, that earlier required several chips, on a single chip. READ MORE

4. Substrate specificity of protein kinases studied with synthetic peptides
Abstract : This thesis concentrates on the substrate specificities of protein kinases A and C (PKA, PKC). Synthetic peptides are used for that purpose, both in soluble and cellulose membrane-bound form. The, stereospecificity of both protein kinases was studied with D-amino acid containing synthetic peptides. READ MORE

5. Effect of Substrate on Bottom-Up Fabrication and Electronic Properties of Graphene Nanoribbons
Abstract : Taking into account the technological demand for the controlled preparation of atomically precise graphene nanoribbons (GNRs) with well-defined properties, the present thesis is focused on the investigation of the role of the underlying metal substrate in the process of building GNRs using bottom-up strategy and on the changes in the electronic structure of GNRs induced by the GNR-metal interaction. The combination of surface sensitive synchrotron-radiation-based spectroscopic techniques and scanning tunneling microscopy with in situ sample preparation allowed to trace evolution of the structural and electronic properties of the investigated systems.
