Tracking active groundwater microbes with D2O labeling to understand their ecosystem function
Microbial activity is key in understanding the contribution of microbial communities to ecosystem functions. Tracing turnover of individual13C labeled carbon sources provides limited information about...
Publications3rd generation poly(ethylene imine)s for gene delivery
Cationic polymers play a crucial role within the field of gene delivery offering the possibility to circumvent (biological) barriers in an elegant way. However, polymers are accompanied either by a high...
PublicationsRecursive feature elimination in Raman spectra with support vector machines
The presence of irrelevant and correlated data points in a Raman spectrum can lead to a decline in classifier performance. We introduce support vector machine-based recursive feature elimination into the...
PublicationsMultiplexed holograms in phenanthrenequinone–polymethylmethacrylate composite for microscopic applications
The conditions of multiplexed hologram recording in the layers ofpolymethylmethacrylate (PMMA) with a high content of photosensitive components,phenanthrenequinone (PQ), were analyzed theoretically and...
PublicationsSub-micrometer yttrium iron garnet LPE films with low ferromagnetic resonance losses
Using a liquid phase epitaxy (LPE) technique (1 1 1) yttrium iron garnet (YIG) films with thicknesses of ≈100 nm and surface roughnesses as low as 0.3 nm have been grown on(1 1 1) gadolinium gallium...
PublicationsA characterization of the magnetically induced movement of NdFeB-particles in magnetorheological elastomers
Magnetorheological elastomers are a type of smart hybrid material where elastic properties of a soft elastomer matrix are combined with magnetic properties of magnetic micro particles. This combination...
PublicationsBroadband single-mode single-polarization passive fully-aperiodic large-pitch fibers
Two evolutions of fully-aperiodic large-pitch fiber designs employing few stress-applying parts are presented. The induced elasto-optic stress discriminates the two orthogonal polarization modes (LP01x...
Publications3D nanoSQUID based on tunnel nano-junctions with an energy sensitivity of 1.3 h at 4.2 K
We present electrical characterization including throughout noise investigations of a three-dimensional nano Superconducting QUantum Interference Device (nanoSQUIDs) fabricated with Focused Ion Beam sculpturing...
PublicationsMultiplex coherent anti-Stokes Raman scattering microspectroscopy of brain tissue with higher ranking data classification for biomedical imaging
Multiplex Coherent Anti Stokes Raman Scattering (MCARS) microscopy was carried out to map a solid tumor in mouse brain tissue. The border between normal and tumor tissue was visualized using support vector...
PublicationsExternally tunable fibers for tailored nonlinear light sources
Hybrid-material optical fibers that enable supercontinuum generation show potential for application in widely tunable broadband light sources.
