2 MW peak power generation in fluorine co-doped Yb fiber prepared by powder-sinter technology
We report on the first implementation of a fluorine co-doped large-mode-area REPUSIL fiber for high peak power amplification in an ultrashort-pulse master oscillator power amplifier. The core material...
PublicationsBeyond 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...
PublicationsMolecular investigations on a chimeric strain of Staphylococcus aureus sequence type 80
An Eritrean patient was admitted with suspected tuberculous cervical lymphadenitis. While no mycobacteria were detected in pus from this process, culture yielded PVL-positive, methicillin-susceptible Staphylococcus...
Publications2-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...
PublicationsRapid 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...
PublicationsNew approaches in component design for dye-sensitized solar cells
The present perspective presents a number of issues related to the current direction of DSSC research, with emphasis on the transition from iodide-containing electrolyte to charge-transport media (CTMs),...
PublicationsAutomated 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....
PublicationsAn epidemic CC1-MRSA-IV clone yields false negative test results in molecular MRSA identification assays: a note of caution
We investigated why a clinical meticillin-resistant Staphylococcus aureus (MRSA) isolate yielded false-negative results with some commercial PCR tests for MRSA detection. We found that an epidemic European...
PublicationsResponse 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...
PublicationsOptical microresonator arrays of fluorescence-switchable diarylethenes with unreplicable spectral fingerprints
High-security identification requires authentication that is hard to counterfeit and replicate. For anti-counterfeiting data storage and rewritable memory devices, chromic materials are adoptable, where...
