DISSERTATION TU DRESDEN MASCHINENWESEN

The path to the scientist title is experience- and network-oriented! It is observed in several studies, that the profile losses and hence the compressor performance of embedded stages are altered compared to isolated blade rows due to blade row interaction effects. Moreover, closely packed arrays of parallel SWCNTs are required in order to sustain the relatively large currents found in high frequency devices. Would you like to perform post-doctoral work at the Department of Mechanical Engineering? This thesis comprises detailed and systematic experimental investigations in to the fabrication of horizontally aligned SWCNTs using both post growth Dielectrophoresis and direct growth CVD methods. For these reasons the effects of the periodical unsteady flow field have to be considered during the design process of turbomachines.

The model has been further extended to consider time-dependent external electric fields in which a special emphasis is given to the profiles in which this external parameter can interact with the associated molecular complex. We honour the successful qualification of young academics and use this festive occasion to give award and prizes that document the top achievements of our faculty: The data significantly advances our understanding of horizontally aligned carbon nanotubes by both post synthesis alignment as well as directly as-synthesized routes. The blades and vanes, moving relatively to each other, aerodynamically interact because of the viscous wakes and the potential effects of the blades. Two key areas still require further development before the realization of large-scale nanoelectronics. The systematic studies allow for a detailed understanding of the growth mechanisms of catalyst and catalyst-free grown SWCNTs to be elucidated.

Doctoral and post-doctoral degrees mean more than just scientific qualification work. In addition, the wakes and potential effects superimpose with other flow patterns, for instance the tip clearance vortices and other secondary flow phenomena. TU Dresden has a broad spectrum of Humanities and Social Sciences and is in an excellent position to conduct interdisciplinary research on the big questions of our times. Critical blade dissertattion are excited if the frequency of the aerodynamic stimulation matches the natural frequencies of the blades.

The extraordinary properties of the single wall carbon nanotubes SWCNTs have stimulated an enormous amount of research towards the realization of SWCNT-based products for different applications ranging form nanocomposites to nanoelectronics. The aim of this work is to develop new strategies for alignment by self assembly of such one-dimensional nanomaterials like carbon nanotubes using combination of different conventional techniques.

Disssertation systematic studies allow for a detailed understanding of the growth mechanisms of catalyst and catalyst-free grown SWCNTs to be elucidated. Dense mats of Al5BO9 nanowires cover large areas dissertatuon the substrate that were previously relatively flat.

The process is enhanced by a high temperature and the presence of pre-existing superficial defects cracks, terraces, etc. For these reasons the effects of the periodical unsteady flow field have to be considered during the dissrtation process of turbomachines.

You can also decide for publishing in print or with a publisher. Appropriate functionality of m-QCAs involves a complex relationship between quantum mechanical effects, such as electron transfer processes within the molecular building blocks, and electrostatic interactions between cells. This includes results on the periodical unsteady flow field within the axial gaps between the blade rows as well as the flow field within the rotor blade passages.

Their high charge mobility, exceedingly good current-carrying capacities and ability to be either semiconducting or metallic render them ideal building blocks for nanoelectronics. Finally, the validation of these findings is carried out via comparison with accesible experimental results and opening the gate to plausible strategies where the paradigm can be implemented. While metallic nanoparticles nucleate and grow SWCNTs, opened and activated fullerene structures are used for all carbon catalyst-free growth of single wall and double wall carbon nanotubes.

The main emphasis is given to study the interaction between localized charge-carrier molecular states and the delocalized surface states. Skip to secondary navigation.
