Precompensation of the thermal-induced refractive index changes into a fully aperiodic LPF for heat load resilience
In this paper, a strategy consisting in pre-compensating the thermal-induced transverse refractive index changes is undertaken to push further the appearance threshold of a multimode regime. First, a standard...
PublikationenMobility investigations of magnetic nanoparticles in biocomposites
Biocompatible composites, consisting of magnetite nanoparticles embedded into a matrix of meltable dextran ester are presented, which can be softened under an induced alternating magnetic field and may...
PublikationenMeltable magnetic biocomposites for controlled release
New biocompatible composites with adjustable melting point in the range of 30−140 °C, consisting of magnetite nanoparticles embedded into a matrix of meltable dextran fatty acid ester are presented...
PublikationenConcentric dot-ring metal nanostructures prepared by colloidal lithography
A large scale production of well-defined metallic nanostructures represents an important step for a real application of plasmonic technology. Here, we report about a novel development in colloidal lithography...
PublikationenTailored loss discrimination in indefinite metamaterial-clad hollow-core fibers
We analyze the modal attenuation properties of silica hollow-core fibers with a gold-wire based indefinite metamaterial cladding at 10.6 µm. We find that by varying the metamaterial feature sizes and...
PublikationenNanocapillary Electrokinetic Tracking for Monitoring Charge Fluctuations on a Single Nanoparticle
We introduce nanoCapillary Electrokinetic Tracking (nanoCET), an optofluidic platform for continuously measuring the electrophoretic mobility of a single colloidal nanoparticle or macromolecule in vitro...
PublikationenInvestigation of vacuum deposited hybrid coatings of protic organic UV absorbers embedded in a silica matrix used for the UV protection of Polycarbonate glazing
A study of vacuum-deposited organic–inorganic hybrid coatings for UV protection of polycarbonate is presented. UV-absorbing compounds which are commonly used for PC were embedded in a silica matrix by...
PublikationenZnO Nanostructures-based Dye-sensitized Solar Cells using TEMPO+/TEMPO Redox Mediator and Ruthenium(II) Complexes with 1,2,3-Triazole-derived Ligands
A series of thiocyanate-free bis(tridentate) ruthenium(II) complexes incorporating 1,2,3-triazole-derived NNN-, NCN-, and CNC-coordinating ligands has been employed for sensitizing ZnO photoanodes for...
PublikationenRecognition of Tumor Cells by Immune-SERS-Markers in a Microfluidic Chip at Continuous Flow R
SERS labels conjugated with anti-EpCAM antibodies are used to distinguish breast cancer cells and leukocytes in a microfluidic chip. Raman spectra of leukocytes, SERS-labelled MCF-7 cancer cells and polystyrene...
PublikationenIron incorporation in biosilica of the marine diatom Stephanopyxis turris: dispersed or clustered?
Iron incorporation into diatom biosilica was investigated for the species Stephanopyxis turris. It is known that several “foreign” elements (e.g., germanium, titanium, aluminum, zinc, iron) can be...
