ORMOCER coated Fiber-Optic Bragg Grating Sensors at Cryogenic Temperatures
ORMOCER coated Fiber-Bragg-Gratings (FBG) were investigated at cryogenic temperatures. Below T = 40 K the Bragg wavelength of uncoated FBG is nearly independent on temperature. ORMOCER coated FBG are temperature...
PublikationenExcited-state annihilation in a homodinuclear ruthenium complex
Ultrafast excited-state annihilation in a homodinuclear ruthenium complex is observed. This coordination compound constitutes a model system for approaches towards artificial photosynthetic systems. The...
PublikationenSimultaneous topographic and amperometric membrane mapping using an AFM probe integrated biosensor
The investigation of the plasma membrane with intercorrelated multiparameter techniques is a prerequisite for understanding its function. Presented here, is a simultaneous electrochemical and topographic...
PublikationenAu/Ag/Au double shell nanoparticles with narrow size distribution obtained by continuous micro segmented flow synthesis
In this paper we present a two-step micro continuous flow-through method for synthesizing colloidal dispersions of noble metal core/shell and multishell nanoparticles in aqueous solutions in the presence...
PublikationenPlasmonic Nanofabrication by Long-Range Excitation Transfer via DNA Nanowire
Driven by the demand for ongoing integration and increased complexity of today’s microelectronic circuits, smaller and smaller structures need to be fabricated with a high throughput. In contrast to...
PublikationenFiber Bragg grating based spatially resolved characterization of flux-pinning induced strain of rectangular-shaped bulk YBCO samples
We report on measurements of the spatially resolved characterization of flux-pinning induced strain of rectangular shaped bulk YBCO samples. The spatially resolved strain measurements are accomplished...
PublikationenNonlinear microscopy, infrared, and Raman microspectroscopy for brain tumor analysis
Contemporary brain tumor research focuses on two challenges: First, tumor typing and grading by analyzing excised tissue is of utmost importance for choosing a therapy. Secondly for prognostication the...
PublikationenSpectrally shaped light from supercontinuum fiber light sources
Supercontinuumfiber light sources with their extremely wide wavelength spectrumcan provide new options for achieving specific wavelength distributions in a very flexible way. Two concepts for the combination...
PublikationenFluorescence-based fixative and vital staining of lipid droplets in Caenorhabditis elegans reveal fat stores using microscopy and flow cytometry approaches
The proportions of body fat and fat-free mass are determining factors of adiposity-associated diseases. Work in Caenorhabditis elegans has revealed evolutionarily conserved pathways of fat metabolism....
PublikationenTunable optical setup with high flexibility for spectrally resolved CARS microscopy
A simplified setup for coherent anti-Stokes Raman scattering (CARS) microscopy is introduced which allows for recording CARS images with 30 cm-1 excitation bandwidth for probing Raman bands between 500...
