In vivo imaging of hepatic excretory function in the rat by fluorescence microscopy
Applying intravital fluorescence microscopy, we assessed sinusoidal delivery and biliary clearance of two different polymethine dyes. DY635, a benzopyrylium-based hemocyanine dye with shorter excitation...
PublikationenInfluence of Surface Treatment and Passivation on Photoluminescence of Wet Chemically Etched Silicon
Wet Chemical Etching (WCE) of Silicon is an adaptable method to create either films of freestanding nanowires on a silicon substrate or to produce spongy porous silicon structures. Especially the first...
PublikationenSimulation of Symmetrically Doped Silicon Nanowire Solar Cells
Silicon nanowire solar cells were simulated using the Silvaco TCAD software kit. For optimization of speed the simulations were performed in cylinder coordinates with cylindrical symmetry. Symmetric doping...
PublikationenIncreased flux pinning in YBa2Cu3O7−delta thin-film devices through embedding of Au nano crystals
We prepared direct-current superconducting quantum interference device (dc-SQUID) gradiometers consisting of a single YBa2Cu3O7− (YBCO) layer on SrTiO3 (STO) bicrystal substrates. The superconducting...
PublikationenInfluence of multiple protonation on the initial excitation in a black dye
Solvent pH influences electronic and optical properties of photoactive systems by protonation/deprotonation of basic/acidic positions. In this study a joint experimental and theoretical approach is presented...
PublikationenEngineering of YBa2Cu3O7–δ grain boundary Josephson junctions by Au nanocrystals
We prepared and investigated grain boundary Josephson junctions based on 3 SrTiO bicrystal substrates. During the deposition of 2 3 7 YBa Cu O -δ (YBCO) gold nanocrystals forming from an intermediate...
PublikationenAtomic layer deposited ZnO:Al for nanostructured silicon heterojunction solar cells
For transparent front contacts of nanostructured silicon solar cells aluminum doped zinc oxide (ZnO:Al), deposited by atomic layer deposition (ALD), is investigated. For this purpose it is crucial that...
PublikationenMicrowave-assisted phase separation of alkali-borosilicates in the production of nanoporous glasses
The influence of a hybrid thermal processing on the spinodal decomposition of sodium borosilicate glasses was investigated. The pore diameter of the resulting porous glasses is a function of the parameters...
PublikationenSynthesis and characterization of superparamagnetic nanoparticles coated with fluorescent gold nanoclusters
Multifunctional nanoparticles (NPs) combining the superparamagnetism of Mn-Zn-ferrite and the fluorescence property of gold nanoclusters have been prepared by wet chemistry. Magnetic NPs synthesized by...
PublikationenOptical single-particle detection in nanoholes towards simple parallel detection of molecular binding events
A novel scheme for the optical detection of a few or even single gold nanoparticle labels is introduced. It utilizes sub-wavelength holes in a chromium layer on a glass substrate, where a bioaffinity reaction...
