First-order sapphire fiber Bragg gratings for high temperature sensing
Sapphire fiber Bragg gratings (SFBG) are presented as a new kind of high temperature sensor that isnot sensitive to electromagnetic fields and can be operated in air as well as inert atmosphere. Forinscription...
PublikationenLOC-SERS: A promising closed system for the identification of mycobacteria
A closed droplet based lab-on-a-chip (LOC) device has been developed for the differentiation of six species of my-cobacteria, i.e., both Mycobacterium tuberculosis complex (MTC) and nontuberculous mycobacteria...
PublikationenDiscretely tunable thulium-doped fiber-based polarization-maintaining master oscillator power amplifier using fiber Bragg grating arrays as spectral filters
Thulium- (Tm-)doped fiber lasers offer a broad emission bandwidth in the 2-µm region, providing the perfect basis to develop broadly tunable laser sources, e.g. for spectroscopic applications. Recently,...
PublikationenEuropean and International Initiatives in the Field of Artificial Photosynthesis
In a context of the rising awareness of the need for alternative renewable energy sources to achieve a low- carbon society, artificial photosynthesis, that is,i.e. the possibility to directly convert solar...
PublikationenSurface enhanced Raman scattering based reaction monitoring of in vitro decyclization of creatinine → creatine
Creatinine → Creatine decyclization is an important reaction where we obtain a beneficial compound from a toxic substance. Decyclization of creatinine at basic pH has been monitored in vitro by time...
PublikationenHigh-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...
PublikationenCellular 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...
Publikationen100 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...
PublikationenProduction 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...
PublikationenExperimental 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...
