In vitro monitoring of ring opening of leflunomide: A Surface Enhanced Raman Scattering and DFT based approach
The in vitro mechanism of ring opening of leflunomide resulting in formation of a metabolite A771726 has been studied by time series surface enhanced Raman spectra using NaOH buffer at pH ~10. The decomposition...
PublicationsSurface enhanced Raman scattering investigation of two novel piperazine carbodithioic acids adsorbed on Ag and ZnO nanoparticles
In this work piperazine-1-carbodithioic acid (PZCDT) and piperazine-1,4-dicarbodithioic acid (PZbCDT) were synthesized. These analytes PZCDT and PZbCDT have chair conformations, which is expected to give...
PublicationsPlasmon-driven sequential chemical reactions in an aqueous environment
Plasmon-driven sequential chemical reactions were successfully realized in an aqueous environment. In an electrochemical environment, sequential chemical reactions were driven by an applied potential and...
PublicationsIsothermal DNA origami folding: avoiding denaturing conditions for one-pot, hybrid-component annealing
The DNA origami technique offers great potential for nanotechnology. Using biomolecular self-assembly, defined 2D and 3D nanoscale DNA structures can be realized. DNA origami allows the positioning of...
PublicationsAbstimmbare Faserlaser basierend auf Faser-Bragg-Gitter Arrays als spektrale Filter
Faserlaser haben basierend auf einer hervorragenden Strahlqualität im Einmodenbetrieb und dem robusten sowie hocheffizienten Aufbau viele Anwendungsgebiete in der Industrie, Forschung sowie Medizintechnik...
PublicationsEin faserintegriertes Konzept zur Abstimmung der Emissionswellenlänge gepulster Faserlaser
In dieser Arbeit wird ein neues Abstimmprinzip für die Emissionswellenlänge gepulster Faserlaser vorgestellt, dass auf einem Faser-Bragg-Gitter (FBG) Array als spektraler Filter basiert. Die experimentelle...
PublicationsAn Electron Beam Profile Instrument Based on FBGs
Along with the dose rate and the total irradiation dose measurements, the knowledge of the beam localization and the beam profile/ energy distribution in the beam are parameters of interest for charged...
PublicationsSimple structured illumination microscope setup with high acquisition speed by using a spatial light modulator
We describe a two-beam interference structured illumination fluorescence microscope. The novelty of the presented system lies in its simplicity. A programmable spatial light modulator (ferroelectric LCoS)...
PublicationsFree charge carrier absorption in silicon at 800 nm
The transmission of a Ti:sapphire laser beam (c. w. and fs pulsed operation at 800 nm) through a 10 µm thin oxidized silicon membrane at 45° angle of incidence at first increases with the incident laser...
PublicationsModified bibenzimidazole ligands as spectator ligands in photoactive molecular functional Ru-polypyridine units? Implications from spectroscopy
The photophysical properties of Ruthenium-bipyridine complexes bearing a bibenzimidazole ligand were investigated. The nitrogens on the bibenzimidazole-ligand were protected, by adding either a phenylene...
