Engineering 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...
PublicationsAtomic 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...
PublicationsMicrowave-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...
PublicationsSynthesis 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...
PublicationsOptical 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...
PublicationsUltrafast Circular Dichroism Study of the Ring Opening of 7-Dehydrocholesterol
UV-femtosecond time-resolved circular dichroism (TRCD) spectroscopy has been used to study the ultrafast changes of chirality in a small molecular biological paradigm sample, 7-dehydrocholeserol (7-DHC)....
PublicationsOrigin of salt mixtures and mixed salts in atmospheric particulate matter
The atmospheric particulate matter contains components of natural and anthropogenic origin, some of them are sulphates and nitrates. Considering the usual occurrence of many ions in the atmosphere and...
PublicationsAssessment of two isolation techniques for bacteria in milk towards their compatibility with Raman spectroscopy
The identification of single microorganism in food samples by conventional plating techniques or molecular genetic methods requires a time consuming enrichment step. Raman spectroscopy in combination with...
PublicationsRuthenium(II) photosensitizers of tridentate click-derived cyclometalating ligands: A joint experimental and computational study
A systematic series of heteroleptic bis-tridentate ruthenium(II) complexes of click-derived 1,3-bis(1,2,3- triazol-4-yl)benzene N^C^N-coordinating ligands was synthesized, analyzed by single crystal X-ray...
PublicationsSynthesis and photophysics of a novel photocatalyst for hydrogen production based on a tetrapyridoacridine bridging ligand
Molecular photocatalysts allow for selectively tuning their function on a molecular levelbased on a detailed understanding of their chemical and photophysical properties. This contribution reports the...
