Removing image artefacts in wire array metamaterials
Hyperlenses and hyperbolic media endoscopes can overcome the diffraction limit by supporting propagating high spatial frequency extraordinary waves. While hyperlenses can resolve subwavelength details...
PublikationenTip-Enhanced Raman Spectroscopy
Tip-enhanced Raman spectroscopy (TERS), a combination of Raman spectroscopy and apertureless near-field scanning optical microscopy using a metallic tip which resonates with the local mode of the surface...
PublikationenAuto-calibration of a Lens-free Holographic Microscope With Microfluidic Chip for Medical Application
The lens-free inline holographic microscopy will be extended by the use of microfluidic chips with a total thickness up to 5.5 mm. The microfluidic chip contains an integrated pinhole mask and additional...
PublikationenThe waterfront of Karlburg and Salz in the Early and High Middle Ages – interdisciplinary (geo)archaeological and geophysical studies
For a deeper understanding of the relationship between a riverine settlement und a nearby river in the Early and High Middle Ages, some basic characteristics of inland navigation at this time have to be...
PublikationenFossata Magna – a canal contribution to harbour construction in the 1st millennium AD
Navigable canals are an exception in the 1st millennium AD in central Europe – but not as rare as often thought. Although they form key elements of the European harbour network, only a few prominent...
PublikationenInterpretation of the optical transfer function: Significance for image scanning microscopy
The optical transfer function (OTF) is widely used to compare the performance of different optical systems. Conventionally, the OTF is normalized to unity for zero spatial frequency, but in some cases...
PublikationenHäfen verbinden. Neue Befunde zu Verlauf, wasserbaulichem Konzept und Verlandung des Karlsgrabens, in: Häfen im 1. Millennium AD
Naturräumlich bedingt ist das binnenländische Hafennetzwerk in zahlreiche schifffahrtstechnisch eigenständige Bestandteile gegliedert. Ihre Grenzen bilden Wasserscheiden, die epochenübergreifend stabile...
PublikationenHafen oder Landeplatz? – Untersuchungen zu Einrichtungen der früh- und hochmittelalterlichen Binnenschifffahrt ausgehend von den Fallbeispielen Karlburg und Salz in Unterfranken, in: Häfen im 1. Millennium AD, Hrsg. Th. Schmidts, M.M. Vučetić
Die archäologische Erforschung früh- und hochmittelalterlicher Binnenhäfen in Mitteleuropa ist ein Desiderat und eine Herausforderung. Das bauliche Spektrum, das unter dem Begriff Binnenhafen subsumiert...
PublikationenEffect of annealing on the sub-bandgap, defects and trapping states of ZnO nanostructures
Annealing treatment was applied to different mesoporous ZnO nanostructures prepared by wet chemical synthesis, i.e. nanoflowers(NFs), spherical aggregates (SPs), and nanorods (NRs). The sub-bandgap,defect...
PublikationenApplicability of an economic diode laser emitting at 980 nm for preparation of polycrystalline silicon thin film solar cells on glass
Recently, polycrystalline silicon thin film solar cells on glass are fabricated by a laser induced liquid phase crystallization (LPC) process. This study compares a new economic diode laser emitting a...
