Charged domains in ferroelectric, polycrystalline yttrium manganite thin films resolved with scanning electron microscopy
We have investigated ferroelectric charged domains in polycrystalline hexagonal yttrium manganite thin films (Y1Mn1O3, Y0.95Mn1.05O3, Y1Mn0.99Ti0.01O3, and Y0.94Mn1.05Ti0.01O3) by scanning electron microscopy...
PublikationenResponse of the wood-decay fungus Schizophyllum commune to co-occurring microorganisms
Microorganisms are constantly interacting in a given environment by a constant exchange of signaling molecules. In timber, wood-decay fungi will come into contact with other fungi and bacteria. In naturally...
PublikationenAutomated and fast identification of resistant E. coli against the lead drugs of the 3MRGN group using specific Raman marker bands
A Raman-based, strain-independent, semi-automated method is presented which allows the rapid (< 3hours) determination of antibiotic susceptibility of bacterial pathogens isolated from clinical samples....
PublikationenRapid Raman spectroscopic analysis of stress induced degradation of the pharmaceutical drug tetracycline
Stress factors caused by inadequate storage can induce the unwanted degradation of active compounds in pharmaceutical formulations. Resonance Raman spectroscopy is presented as an analytical tool for rapid...
Publikationen2-LED-Spectrophotometer for Rapid On-Site Detection of Pathogens Using Noble-Metal Nanoparticle-Based Colorimetric Assays
Novel point-of-care compatible methods such as colorimetric assays have become increasingly important in the field of early pathogen detection. A simple and hand-held prototype device for carrying out...
PublikationenBeyond Beer’s law: Revisiting the Lorentz-Lorenz equation
In this contribution we show how the Lorentz-Lorenz and the Clausius-Mosotti equations are related to Beer’s law. Accordingly, the linear concentration dependence of absorbance is a consequence of neglecting...
PublikationenTheory of four-wave mixing for bound and leaky modes
We present a comprehensive theory of four-wave mixing in waveguide geometries, providing a rigorous description of the dynamics of both bound as well as leaky modes within a single theoretical framework....
PublikationenBi-metallic Pd/Au Nanoparticles prepared by UV-Excimer Laser exposure
Multi-metallic nanoparticles are useful for applications in biophotonics or catalysis. Metal compounds alter the properties of pure metallic nanoparticles and thus expand the particle performance compared...
PublikationenComparison of multiscale imaging methods for brain research
A major challenge in neuroscience is how to study structural alterations in the brain. Even small changes in synaptic composition could have severe outcomes for body functions. Many neuropathological diseases...
PublikationenFluorescence Microscopy of the HIV-1 Envelope
Human immunodeficiency virus (HIV) infection constitutes a major health and social issue worldwide. HIV infects cells by fusing its envelope with the target cell plasma membrane. This process is mediated...
