Nanostructure development in multicomponent polymer systems and Its characteriz...
Denchev, Z.; Dencheva, Nadya Vasileva; Stribeck, A.; Roth, S.Modern synchrotron beamlines equipped with 2D detection and microfocus offer interesting possibilities for polymer characterization. This work presents several synchrotron X-ray studies performed in multicomponent polymer systems, i.e., nanostructure development under controlled strain, quantification of transcrystallinity phenomena in differently compatibilized blends and determination of structural and concen...
Parallel use of shake flask and microtiter plate online measuring devices (RAMO...
Wewetzer, S. J.; Kunze, M.; Ladner, T.; Luchterhand, B.; Roth, S.; Rahmen, N.; Kloß, R.; Silva, Andrea Costa e; Regestein, L.; Büchs, J.Background Conventional experiments in small scale are often performed in a Black Box fashion, analyzing only the product concentration in the final sample. Online monitoring of relevant process characteristics and parameters such as substrate limitation, product inhibition and oxygen supply is lacking. Therefore, fully equipped laboratory-scale stirred tank bioreactors are hitherto required for detailed studie...
Results on low mass WIMPs using an upgraded CRESST-II detector
Angloher, G.; Bento, A.; Bucci, C.; Canonica, L.; Erb, A.; von Feilitzsch, F.; Iachellini, N. Ferreiro; Gorla, P.; Gütlein, A.; Hauff, D.; Huff, P.The CRESST-II cryogenic dark matter search aims for the detection of WIMPs via elastic scattering off nuclei in CaWO4 crystals. We present results from a lowthreshold analysis of a single upgraded detector module. This module efficiently vetoes low energy backgrounds induced by α-decays on inner surfaces of the detector. With an exposure of 29.35 kg live days collected in 2013 we set a limit on spin-independent...
Energy-dependent light quenching in CaWO4 crystals at mK temperatures
Strauß, R.; Angloher, G.; Bento, A.; Bucci, C.; Canonica, L.; Carli, W.; Erb, A.; von Feilitzsch, F.; Gorla, P.; Gütlein, A.; Hauff, D.; Hellgartner, D.ScintillatingCaWO4 single crystals are a promising multi-element target for rare-event searches and are currently used in the direct dark matter experiment CRESST (Cryogenic Rare Event Search with Superconducting Thermometers). The relative light output of different particle interactions in CaWO4 is quantified by quenching factors (QFs). These are essential for an active background discrimination and the identi...
