High-Temperature Strain Sensing using Sapphire Fibers with inscribed first-order Bragg gratings
Strain sensor designs and strain measurements based on single crystal sapphire fibers with inscribed first order fiber Bragg gratings for applications up to 600°C are presented. We report on all the details...
PublicationsCellular uptake of PLA nanoparticles studied by light and electron microscopy: synthesis, characterization and biocompatibility studies using an iridium(III) complex as correlative label
We present the synthesis of polylactide by ring-opening polymerization using a luminescent iridium(III) complex acting as initiator. The polymer was formulated into nanoparticles, which were taken up by...
Publications100 W Average Power Femtosecond UV Laser for Ultra-High Photon Flux XUV Sources
We present a femtosecond laser system delivering up to 100 W of average power at 343 nm with nearly diffraction-limited beam quality. This laser source is expected to generate XUV radiation with ultra-high...
PublicationsProduction of monodispersed magnetic polymeric microspheres in a microfluidic chip and 3D simulation
The principles of droplet generation due to hydrodynamic instability in a microfluidic flow-focusing system were used to design and optimize a microfluidic chip that can be used for the direct production...
PublicationsExperimental system design for the integration of trapped-ion and superconducting qubit systems
We present a design for the experimental integration of ion trapping and superconducting qubit systems as a step towards the realization of a quantum hybrid system. The scheme addresses two key difficulties...
PublicationsEvaluation of a SQUID-based receiver for transient electromagnetics in Bad Frankenhausen, Germany
Within the framework of the multidisciplinary research project called INFLUINS, INte- grated FLUid dynamics IN Sedimentary basins, we use a highly sensitive magnetic field receiver based on Superconducting...
PublicationsMicron-sized gold-nickel alloy wire integrated silica optical fibers
Hybrid fibers are an emerging class of optical devices which allow integration of increasingly sophisticated functionality into fibers. Fibers containing metallic micro- and nanowires are particularly...
PublicationsElectronic structure of silicon nanowires formed by MAWCE method
Essential differences in electronic structure and phase composition of silicon nanowires were demonstrated by X-ray spectroscopy technique. Silicon wires massives have been produced by metal assisted wet...
PublicationsStudies of Silicon Nanoparticles Uptake and Biodegradation in Cancer Cells by Raman Spectroscopy
In-vitro Raman micro-spectroscopy was used for diagnostics of the processes of uptake and biodegradation of porous silicon nanoparticles (SiNPs) in breast cancer cells (MCF-7 cell line). Two types of nanoparticles,...
PublicationsNew airborne methods and procedures for the exploration of mineral resources – An overview of BGR activities
Airborne geophysics is well established in the field of exploration of mineral deposits. Most of the methods applied in this respect are mandatory in order to define an exploration target in the subsurface...
