The MASCOT Radiometer MARA for the Hayabusa 2 Mission
The MASCOT radiometer MARA is a multi-spectral instrument which measures net radiative flux in six wavelength bands. MARA uses thermopile sensors as sensing elements, and the net flux between the instrument...
PublicationsRaman Spectroscopic Characterization of Packaged L. pneumophila Strains Expelled by T. thermophila
The intracellular lifestyle of L. pneumophila within protozoa is considered to be a fundamental process that supportsits survival in nature. However, after ingesting the cells of L. pneumophila some protozoa...
PublicationsCore-shell diodes for particle detectors
High performance particle detectors are needed for the fundamental research in the high energy physics in exploring for Higgs-boson, dark matter, anti-matter, gravitational wave, and proof of the standard...
PublicationsMultigas Leakage Correction in Static Environmental Chambers Using Sulfur Hexafluoride and Raman Spectroscopy
In static environmental chamber experiments, the precision of gas flux measurements can be significantly improved by a thorough gas leakage correction to avoid underor overestimation of biological activity...
PublicationsWhy bother about gradients? – SQUID based full tensor magnetic gradiometer for mineral exploration
Superconducting Quantum Interference Devices (SQUIDs) are still known to be the most sensitive detectors of magnetic flux. The recent sensor techno-logies reached a mature state and thus enabled to build...
PublicationsGiant Magnetoresistance-Stack Optimization for Current Sensor Application With Low Hysteresis and a Temperature-Independent Sensitivity at Low Current
We report on a galvanic isolated current sensor that operates on the principle of the GMR-effect (giant magneto resistive effect). Due to an optimized combination of uniaxial ...
PublicationsAnwendung SERS-aktiver Nanostrukturen in der Medikamentenüberwachung und Lebensmittelanalytik
Die oberflächenverstärkte Raman-Spektroskopie (SERS), die auf der Verwendung von funktionalen Metallnanostrukturen beruht, zeigt ein großes Potential als analytische Methode. Dies wird auf ihre molekulare...
PublicationsPotential of Ypt1 and ITS gene regions for the detection of Phytophthora species in a lab-on-a-chip DNA hybridization array
A novel DNA-chip hybridization assay that uses the ras-related GTP-binding protein 1 gene (Ypt1) was developed for the identification of several devastating Phytophthora species. The hybridization was...
PublicationsHigh precision attachment of silver nanoparticles on AFM tips by dielectrophoresis
AFM tips are modified with silver nanoparticles using an AC electrical field. The used technique works with sub-micron precision and also does not require a chemical modification of the tip. Based on the...
PublicationsRecent Progresses in Integrated Nanoplasmonic Devices Based on Propagating Surface Plasmon Polaritons
The propagating surface plasmons on Ag nanowires (NW) have been investigated for over 10 years and which were interpreted with basic modes combining and hybridisation. Since the high confinement of the...
