Influence of the flow profile to Lorentz force velocimetry for weakly conducting fluids - an experimental validation. - In: Measurement science and technology, ISSN 1361-6501, Bd. 27 (2016), 12, S. 125306, insges. 9 S.
The Lorentz force velocimetry (LFV) is a highly feasible contactless method for measuring flow rate in a pipe or in a channel. This method has been established for liquid metal flows but also for weakly conducting electrolytes where the Lorentz force amplitudes are typically six orders smaller than the ones from liquid metal flows. Due to an increased resolution of the Lorentz force measurements which was the main focus of research in the last years, now it is possible to investigate the influence of the flow profile on the amplitude of the Lorentz force. Even if there is a semi-theoretical approach an experimental validation is still outstanding. Therefore we have tested symmetric and asymmetric flow profiles to test the LFV for weakly conducting fluids for typical industrial flows. Salt water has been used as a test electrolyte with constant values of the electrical conductivity from 0.035 to 20 S m-1 and of the flow velocity in a range of 0.5-3 m s-1. We confirmed by extensive measurements that LFV is a suitable method for flow measurements even for different flow profiles within 5% measurement uncertainty. For a wide range of applications in research and industry the LFV should be not sensitive to various flow profiles.

Mesoscopically Bi-continuous Ag-Au hybrid nanosponges with tunable plasmon resonances as bottom-up substrates for surface-enhanced Raman spectroscopy. - In: Chemistry of materials, ISSN 1520-5002, Bd. 28 (2016), 21, S. 7673-7682
Ag-Au hybrid nanosponges (NSs) with controlled porosity and composition ratio were fabricated through the cyclic electroless deposition of Ag into the porous Au NSs. In the Ag-Au hybrid NSs, both Au and Ag components with mesoscaled ligament size are bicontinuously percolated over the entire structure. The plasmonic properties of the Ag-Au hybrid NSs differ clearly from those of the Au NSs and the solid Au-Ag alloy nanoparticles, and two distinct plasmon peaks were observed which can be attributed to Au and Ag components, respectively. The plasmonic properties can be well tuned by controlling the cycles of Ag deposition. Both plasmon peaks attributed to Au and Ag components blue shift with increasing amount of Ag. The volume porosity decreases upon increasing amount of deposited Ag. The results of the theoretical calculations reveal that the deceasing porosity could play an important role in the blue shift. Moreover, the Ag-Au hybrid NSs exhibit higher sensitivity in surface-enhanced Raman spectroscopy (SERS) detection of butter yellow (BY) than the Au NSs due to the presence of Ag and of the porous structure. Also, the as-prepared structures present a built-in preference for hydrophobic analytes.
