Cryogenic bolometers for astronomical observations in the sub-mm range
Cryogenic bolometers are adequate sensing devices for sub-millimeter observations. They are used for instrumentation in radio telescopes like the Atacama Pathfinder Experiment (APEX), which is a 12-m radio...
PublikationenVinculin binding angle in podosomes revealed by high resolution microscopy
Podosomes are highly dynamic actin-rich adhesive structures formed predominantly by cells of the monocytic lineage, which degrade the extracellular matrix. Normal podosome formation and dissociation accompanies...
PublikationenErzeugung breitbandiger und kohärenter Superkontinuumstrahlung in normaldispersiven optischen Fasern
Supercontinua (SC) für zeitlich sensitive Anwendungen wie z.B. in der Pump-Probe-Spektroskopie werden heutzutage mit Energien von einigen 10 µJ in nichtlinearen optischen Kristallen mit kurzer transversaler...
PublikationenHigh-Pressure Synthesized Nanostructural MgB2 Materials With High Performance of Superconductivity, Suitable for Fault Current Limitation and Other Applications
A variety of samples made via different routes were investigated. Samples are nanostructured (average grain sizes are about 20 nm). The advantage of high-pressure (HP)-manufactured (2 GPa, 800–1050 C,...
PublikationenStructured illumination microscopy of autofluorescent aggregations in human tissue
Sections from human eye tissue were analyzed with Structured Illumination Microscopy (SIM) using a specially designed microscope setup. In this microscope the structured illumination was generated with...
PublikationenLow temperature SQUID magnetometer systems for geophysical exploration with transient electromagnetics
Geophysical exploration is getting more and more difficult – many of the easily explorable ore-bodies have been discovered and are being exploited. Finding new mines requires new technologies and tools....
PublikationenTowards a monolithic fiber laser with deep UV femtosecond-induced fiber Bragg gratings
Fiber Bragg grating inscription with a deep ultraviolet (DUV) femtosecond laser and two beam interferometry allows grating inscription in germanium-free fibers without classical UV photosensitivity. Therefore...
PublikationenOptical Fiber Tips for Nanoscopic Applications
Silica-based, metal-coated fiber tips (tapers) are used in a variety of spectroscopic and micro-/ nanoscopic applications (e.g. AFM, SNOM, TERS). The optical resolution of such measurement systems is dependent...
PublikationenTowards multiple readout application of plasmonic arrays
In order to combine the advantages of fluorescence and surface enhanced Raman spectroscopy (SERS) using the same chip platform a nanostructured gold surface with a unique design allowing both the sensitive...
PublikationenPelagic boundary conditions affect the biological formation of iron-rich particles (iron snow) and their microbial communities
We studied the formation of iron-rich particles at steeply opposing gradients of oxygen and Fe(II) within the redoxcline of an acidic lignite mine lake (pH 2.9). Particles formed had a diameter of up to...
