Variational Approaches to Free Energy Calculations
(2021-01-21)Gradients in free energy are the driving forces of thermodynamic systems. Knowledge thereof thus enables a first-principles understanding of condensed-phase many-body systems such as macromolecular assemblies, colloids or ... -
Vektorfeldkonzepte in der Studieneingangsphase Physik
(2024-04-16)The visualization of vector fields as vector field diagrams finds its application in various physics areas and also provides a valuable learning opportunity for physics students. By visualizing concepts and properties of ... -
Ein Verfahren zur Herstellung zweidimensionaler Röntgenwellenleiter
(2013-07-15)As X-ray beams only weakly interact with matter, conventional refracting optics are not suitable for the use in this energy range. Instead, different approaches replace conventional optics in the X-ray regime, one of them ... -
Verformungsinduzierte Strukturänderungen bei amorphem Ni0.5Zr0.5 in Molekulardynamik-Simulationen
(2006-11-27)The present work investigates the plastic deformation of metallic glasses by the aid of molecular-dynamic simulations. The parameters for the model system are adapted to those for a NiZr-alloy. ... -
Verformungsverhalten nanoskaliger Dünnschichten bei AFM-Indentierung
(2023-02-20)Nanoscaled materials differ in their mechanical properties from their bulk counterparts. Reasons therefore are e. g. the different ratio of surface and volume, which leads to different deformation mechanisms. In the case ... -
Vesicle Adhesion, Fusion, and Neurotransmitter Uptake Studied by Small-Angle X-ray Scattering
(2022-02-15)Synaptic neurotransmission is a highly complex and crucial process in the communication between neuronal cells, and is thus directly related to the complex functions of the neural system, including information processing ... -
Vokaltraktmodellbasierte Schätzung von Steuerparametern eines Moduls zur Sprechernormalisierung
(2000-10-26)Diese Arbeit beschäftigt sich mit der Extraktion von specherspezifischen Parametern des Stimmkanals, die als Steuerparameter eines Moduls zur Sprechernormalisierung dienen sollen. Dazu wurde ... -
Wachstum amorpher Schichten: Vergleich von Experiment und Simulation im Bereich Oberflächenrauhigkeit und mechanische Spannungen
(2001-07-04)Structure formation and mechanical stresses of amorphous and polycrystal films, prepared by evaporation, sputtering and PLD, are investigated, and modelled with the help of Monte-Carlo ... -
Wachstum metallischer Nanoclustern auf Polymeroberflächen
(2005-04-22)Growth and properties of metallic nanoclusters on polymer surfaces lead to interesting physical questions. At the same time clusters on polymers have a high potential with regard to technical ... -
Wachstum und Grenzflächenbeschaffenheit oxidischer Ausscheidungen in Silber
(2003-12-02)The chemical composition of metal/oxide (M/O)- interfaces was studied for an internally oxidized Ag1at.%Mg- and Ag1at.%Mn- alloy with MgO- and Mn3O4- nanoprecipitates in a dilute Ag matrix, ... -
Wachstumsanalyse amorpher dicker Schichten und Schichtsysteme
(2004-07-14)Based on a stochastic partial differential equation, surface morphology evolution of growing amorphous thin films can be described. For enhancement and verification of the applicability to ... -
Wasserstoffabsorption in epitaktischen Niobschichten: eine STM-Studie
(2007-02-19)In this work the phase transition of the system Niobium Hydrogen in thin films was investigated. The epitaxial Niobium films were fabricated using ion sputtering on sapphire substrates. The ... -
Wave optical simulations for x-ray nano-focusing optics
(2012-02-22)Curved x-ray multilayer mirrors focus synchrotron beams down to tens of nano metres. A wave-optical theory describing propagation of two waves in an elliptically curved focusing multilayer ... -
Wechselwirkungen von Gold und Versetzungen in Silizium
(2009-06-04)The knowledge about interactions of different defects in crystalline sillicon are of major importance for the optimisation of the performance of solar cells based on multicrystalline silicon. ... -
Wetting dynamics on soft surfaces
(2023-03-01)Dynamic wetting of a liquid deposited on a soft solid is very common in many biological, medical, and industrial processes. Thus, understanding the interaction between a moving liquid drop and a soft surface remains crucial, ... -
White-Light Mass Determination and Geometrical Modelling of Coronal Mass Ejections
(2019-01-21)Coronal Mass Ejections (CMEs) are explosive large-scale outbursts of the Sun’s coronal plasma and magnetic field. They can induce strong geomagnetic storms at Earth, which pose serious threats to space systems, communications ... -
