Long-term sinonasal carriage of Staphylococcus aureus and anti-staphylococcal humoral immune response in patients with chronic rhinosinusitis

The Optofluidic Light Cage – On-Chip Integrated Spectroscopy Using an Antiresonance Hollow Core Waveguide

Emerging applications in spectroscopy-related bioanalytics demand for integrated devices with small geometric footprints and fast response times. While hollow core waveguides principally provide such conditions,...

Material-specific imaging of nanolayers using extreme ultraviolet coherence tomography

Scientific and technological progress depend substantially on the ability to image on the nanoscale. In order to investigate complex, functional, nanoscopic structures like, e.g., semiconductor devices,...

Photophysics of Ruthenium(II) Complexes with thiazole π-extended Dipyridophenazine Ligands

Transition-metal-based donor−acceptor systems can produce long-lived excited charge-transfer states by visible-light irradiation. The novel ruthenium(II) polypyridyl type complexes Ru1 and Ru2 based...

Extruded suspended core fibers from lanthanum-aluminum-silicate glass

We report the use of the extrusion technique at highest temperatures to date (975 °C -1000 °C) for the fabrication of suspended core fibers (SCFs) from glass with molar composition 65 SiO2-20 Al2O3-15...

Observation of direction instability in a fiber ring laser

We report on the observation of a new phenomenon occurring in a fiber ring laser. This phenomenon is about the transition from an initially bidirectional emission of a reciprocal fiber ring laser to a...

Spatially Resolving the Enhancement Effect in Surface-Enhanced Coherent Anti-Stokes Raman Scattering by Plasmonic Doppler Gratings

Well-designed plasmonic nanostructures cana mediate far and near optical fields and thereby enhance light−matter interactions. To obtain the best overall enhancement, structural parameters need to be...

It Takes Three to Tango – the length of the oligothiophene determines the nature of the long-lived excited state and the resulting photocytotoxicity of a Ru(II) photodrug

TLD1433 is the first Ru(II) complex to be tested as a photodynamic therapy agent in a clinical trial. In this contribution we study TLD1433 in the context of structurally-related Ru(II)- imidozo[4,5-f][1,10]phenanthroline...

Taming Ultrafast Laser Filaments for Optimized Semiconductor–Metal Welding

Ultrafast laser welding is a fast, clean, and contactless technique for joining a broad range of materials. Nevertheless, this technique cannot be applied for bonding semiconductors and metals. By investigating...

Silicon sub-oxides as driving force for efficient light-enhanced hydrogen generation on silicon nanowires

We report efficient light-stimulated hydrogen generation from top-down produced highly doped n-type silicon nanowires (SiNWs) with silver nanoparticles (AgNPs) in water-containing medium under white light...
