Numerical and experimental investigations of mixing in T-shaped and cross-shaped micromixers
The mass transfer within the T-shaped and cross-shaped micromixers have been studied using the CFD and confocal laser scanning microscopy methods. The concentration profiles, based on flow regimes, were...
PublicationsOptical properties of metamaterials based on asymmetric double-wire structures
We performed theoretical and experimental investigations of the magnetic properties of metamaterials based on asymmetric double-wire structures. Using the multipole model for the description of metamaterials,...
PublicationsTumour cell identification by means of Raman spectroscopy in combination with optical traps and microfluidic environments
Raman spectroscopy has been recognized to be a powerful tool for label-free discrimination of cells. Sampling methods are under development to utilize the unique capabilities to identify cells in body...
PublicationsPeriodic Nanostructures: Spatial Dispersion Mimics Chirality
Polarization rotation in isotropic materials is commonly associated with chirality, i.e., structures with a handedness which are not identical with their mirror image. We observe this effect in the visible...
PublicationsDirect observation of temperature dependent excited-state equilibrium in dinuclear ruthenium terpyridine complexes bearing electron-poor bridging ligands
Dinuclear ruthenium-terpyridine complexes, bearing highly conjugated bridging ligands, have been investigated by time and temperature dependent emission spectroscopy, time-dependent density functional...
PublicationsBlue-Emitting Polymers Based on 4-Hydroxythiazoles Incorporated in a Methacrylate Backbone
The synthesis of two new monomers based on 4-hydroxythiazoles, with a non-classical chromophore structure similar to the luciferin dye of glowworms, is presented. These dyes are functionalized with methacrylates...
PublicationsA Heteroleptic Bis(tridentate) Ruthenium(II) Complex of a Click-Derived Abnormal Carbene Pincer Ligand with Potential for Photosensitzer Application
Long live the complex! A heteroleptic ruthenium(II) complex of a click-derived tridentate triazolylidene ligand (see graphic) and the parent terpyridine were prepared and investigated by experimental and...
PublicationsClassification of novel thiazole compounds for sensitizing Ru–polypyridine complexes for artificial light harvesting
A systematical study of the Förster resonance energy transfer (FRET) efficiency between thiazole dyes and a Ruthenium polypyridine complex is presented. While Ruthenium polypyridines are conventionally...
PublicationsMicrofabricated atomic vapor cell arrays for magnetic field measurements
We describe a method for charging atomic vapor cells with cesium and buffer gas. By this, it is possible to adjust the buffer gas pressure in the cells with good accuracy. Furthermore, we present a new...
PublicationsOperation and Accuracy of an Automated Cryocooler-based 10 Volt Josephson Voltage Standard System
A commercially available complete microprocessor controlled, fully automated 10 Volt Josephson voltage standard system operated with a cryocooler was developed in cooperation between IPHT and Supracon....
