Ballistic electron transport in graphene nanodevices and billiards
(2019-10-17)Nanodevices are objects with broad relevance for today's society, which bases its economy, operation, and communication onto digital resources. In ballistic nanodevices, disorder has either negligible or minor impact on ... -
Bayesian structure reconstruction from single molecule X-ray scattering data
(2015-02-11)X-ray free electron lasers (XFEL) offer new possibilities for molecular structure determination in single molecule experiments. In this thesis, I propose and assess two alternative Bayesian approaches, namely Orientational ... -
Beeinflussung des laminar-turbulenten Grenzschichtumschlags durch kontrollierte Anregung stationärer Querströmungsinstabilitäten
(2021-07-09)The delay of laminar-turbulent transition, e.g. on aircraft wings, is of special interest because of the possible drag reduction. To study a nonlinear method for delaying crossflow-dominated transition called Upstream ... -
Beeinflussung des Wachstums von Metall auf Polymer durch die gepulste Laserdeposition
(2014-03-24)Nowadays, fabrication of embedded metal particles in dielectric matrices plays an important role for technical devices, e.g. data storage, sensors or enhancement of efficiency of solar cells. In this work, metal nanoparticles ... -
Bestimmung von Platzbesetzung und Bindungsenergien mittels Atomsondentomographie
(2010-07-22)The site occupation of ternary elements in an intermetallic phase is an important area in materials science. Up to now X-Ray based methods and a TEM based method called Atom Location by ... -
Bewertungskompetenz im Physikunterricht: Entwicklung eines Messinstruments zum Themenfeld Energiegewinnung, -speicherung und -nutzung
(2014-10-27)The aim of this study was the development of a questionnaire, able to assess students’ decision-making competencies related to physics education at upper secondary schools. The chosen contexts deal with the generation, ... -
Beziehung zwischen Struktur und Bruchzähigkeit von Holzzellwänden
(2020-08-12)Wood has very good specific mechanical properties. This is mainly caused by its hierarchical structure, since wood is a composite of polymers that have much worse specific mechanical properties than wood. The relation ... -
Binary Mixtures and Fluids in the presence of Quenched Disorder
(2012-02-21)In the bulk, the critical point of a liquid-gas phase transition or a demxing transition of a binary mixture with short-ranged particle interactions belong to the universality class of the ... -
Biological Matter in Microfluidic Environment - from Single Molecules to Self-Assembly
(2006-08-02)The interior as well as the exterior of cells is governed by networks composed of fibrous proteins. The mesh size of these networks is on the order of micrometers and therefore distinguishes ... -
Biomembranen an Grenzflächen und in synaptischer Geometrie
(2001-02-22)Inhomogeneous distributions of ion channels are ubiquitous in biological membranes and important for many biological functions. Therefore many theoretical models have been set up, which try ... -
Biomolecular space exploration - Phase space and parameter space sampling in realistic protein-lipid environments
(2023-12-11)Lipid composition affects membrane properties and specifically adapted compositions allow biomembranes to fulfill their functions. By altering membrane properties lipids regulate biological processes. Specifically, membrane ... -
Biophysics of Blood Platelet Contraction
(2013-05-21)This work is part of a project on blood platelet contraction using an innovative double approach to experiments. First, we adapted the experimental technique, traction force microscopy (TFM), to our cellular system, and ... -
Boundary layers and wind in turbulent thermal convection
(2014-07-24)This cumulative thesis is based on seven publications and is devoted to the investigation of turbulent thermal convection by means of Direct Numerical Simulations (DNSs). Special focus is placed on the boundary layers and ... -
Braided Actions of DHR Categories and Reconstruction of Chiral Conformal Field Theories
(2016-10-18)Quantum Field Theory (QFT) is our modern understanding of particles and matter at small scales, where quantum behaviour replaces macroscopical phenomena, which are much closer to intuition, and dynamics is rather driven ... -
Branched Flow and Caustics in Two-Dimensional Random Potentials and Magnetic Fields
(2010-09-14)Branched flow is a universal phenomenon of two-dimensional wave or particle flows which propagate through a weak random potential. Its origin is the formation of caustics, which are locations ... -
Branching Fraction Measurement of B± → χc1π+π−K± and Search for a Narrow Resonance with the Belle Experiment
(2014-12-09)The effective QCD colour potential can be derived by studying quarkonia through spectroscopy to determine their masses. In the charmonium spectrum, which is well understood and precisely measured below the DDbar production ... -
