Structured SiN membranes as platform for cryogenic bolometers

Cryogenic bolometers detect radiation by measuring the temperature increase in an appropriate absorber. To achieve sufficient detector sensitivity, we place the bolometer on a SiN membrane. Thermal coupling...

Spectroscopic Investigation of the Ultrafast Photoinduced Dynamics in pi-Conjugated Terpyridines

Time-resolved spectroscopy is applied to investigate the ultrafast relaxation dynamics of several p-conjugated mono-, bis-, tris- and tetrakis(terpyridine) derivatives. This particular series of structurally...

Analysis of the cytochrome distribution via linear and nonlinear Raman spectroscopy

The cytochrome distribution in hyphal tip cells of Schizophyllum commune was visualized using resonance Raman mapping and CARS microscopy. For comparison, resonance Raman mapping and CARS imaging of cytochrome...

Lambda exonuclease pre-treatment for improved DNA-chip performance depends on the relative probe-target position

The hybridisation characteristics of DNA targets to solid phase bound probes, e.g. in DNA microarrays, depend on the probe-target position and on target renaturation if a dsDNA target is used. We investigated...

Quantum behavior of a flux qubit coupled to a resonator

Dual Emission from Highly Conjugated 2,2 ‘:6 ‘:2 ”-Terpyridine Complexes – A Potential Route to White Emitters

Here, we present a new class of terpyridine complexes of the transition-metal ions, iron(II), ruthenium(II), and osmium(II), overcoming the poor emission properties typical for this class of polypyridyl...

Characterization of viscosity dependent residence time distribution in the static micromixer Statmix6

First Direct Comparison of a Cryocooler-Based Josephson Voltage Standard System at 10 V

A commercially available and fully automated 10-V Josephson voltage standard system with a liquid helium free cooling has been developed as a result of the cooperation between the Institute of Photonic...

Synthesis, Characterization, and Electro-Optical Properties of Zn-II Complexes with pi-Conjugated Terpyridine Ligands

A series of zinc(II) bis-terpyridine complexes (see picture) is investigated by means of DFT calculations combined with Bader's quantum theory of atoms in molecules. Raman spectroscopy experiments and...

Multimodal imaging to study the morphochemistry of basal cell carcinoma

Basal cell carcinoma is the most abundant malignant neoplasm in humans, the pathology of which is characterized by an abnormal proliferation of basal cells. Basal cell carcinoma can show a variety of different...
