Ultrafast 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)....
PublikationenOrigin 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...
PublikationenAssessment 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...
PublikationenRuthenium(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...
PublikationenSynthesis 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...
PublikationenThe impact of bromine substitution on the photophysical properties of a homodinuclear Ru–tpphz–Ru complex
Ruthenium–polypyridine complexes play an important role as as photosensitizers in supramolecular photocatalysis. Using multiple Ru-centers within a single supramolecular catalyst might be a promising...
PublikationenPhotophysical Dynamics of a Ruthenium Polypyridine Dye Controlled by Solvent pH
The photophysics of the novel ruthenium dye [Ru(tmBiBzIm)(dppz)(tbbpy)]2+ (tmBiBzIm = 5,5′,6,6′-tetramethyl-2,2′-bibenzimidazole, dppz = dipyrido[3,2-a:2′,3,3′-c]phenazine, tbbpy = 4,4′-di-tert-butyl-2,2′-bipyridine)...
PublikationenSilicon nanowire based heterojunction solar cells
Silicon nanowire solar cells with heterojunctions were prepared on single crystalline silicon wafers. The nanowire arrays were generated by silver catalyzed etching of n-type wafers. After careful removal...
PublikationenThin film solar cells based on diode Laser crystallized polycristalline silicon
Polycrystalline silicon thin film solar cell layer systems on glass were prepared in a two-step process based on first generating a seed layer by diode laser crystallization followed by epitaxial thickening....
PublikationenSilicon nanowire solar cells with a-Si hetero-junction showing 7.3% efficiency
Core-shell silicon nanowire (SiNW) solar cells with an a-Si heterojunction were prepared on SiNW arrays, which were etched into n-type silicon wafers or into n-doped multicrystalline silicon thin films...
