In this paper, we report on the first use of an amperometric fluidic microchip array for the examination of nitric oxide in solution. The array chip is composed of 36 working platinum electrodes on a glass substrate. The electrodes have a diameter of 50 μm ...
We implemented a rotationally-invariant Hubbard U extension to density-functional theory in the Car-Parrinello molecular dynamics framework. with the goal of bringing the accuracy of the DFT + U approach to finite-temperature simulations, especially for li ...
This thesis reports on results of three different experiments of photo-induced structural dynamics in the condensed phase, investigated by time-resolved pump-probe spectroscopy with femtosecond time-resolution. In the first part, we address the ultrafast d ...
The dynamics of the ferric CN complexes of the heme proteins Myoglobin and Hb I from the clam Lucina pectinata upon Soret band excitation is monitored using IR and broad band visible pump-probe spectroscopy. The transient response in the UV-vis spectral re ...
The detection of superparamagnetic iron oxide nanoparticles (SPION) in synoviocytes is reported. Synoviocytes were incubated for 2, 12, 24 and 48 h with 1.5 mg/ml of PVA coated SPION under the influence of magnets (12 h). Particles were well tolerated by t ...
Metal-organic coordination interactions are prime candidates for the formation of self-assembled, nanometer-scale periodic networks with room-temperature structural stability. We present X-ray photoelectron spectroscopy measurements of such networks at the ...
Purified LiAlH4 reacts with fluorinated alcs. HORF to give LiAl(ORF)4 (RF = -CH(CF3)2, 2a; -CMe(CF3)2, 2b; -C(CF3)3, 2c) in 77-90% yield. The crude Li aluminates LiAl(ORF)4 react metathetically with AgF to give the silver aluminates AgAl(ORF)4 (RF = -CH(CF ...
The adsorption behaviour of Si(111)2 x 1 and Si(111)7 x 7 surfaces towards Fe(CO)5 has been investigated in the temperature range 80-300 K and in the exposure range 0.1-1000 L. For both surface reconstructions, the adsorption state is found to be molecular ...
Although cationic metal contaminants can be effectively removed from wastewaters by treatment with biopolymers, application of biopolymers for the removal of anionic contaminants (such as As, Cr(VI), and Se) has been limited. The objective of this study wa ...
