We concentrate on the elucidation of the influence of target length and recognition sequence position on the sensorial performance. The impedimetric measurements are performed in the presence of the redox system ferri-/ferrocyanide and show an increase in charge transfer resistance upon hybridization of ssDNA to the sensor surface. Investigations on the impedimetric signal stability demonstrate a clear influence of the buffers used during the sensor preparation and the choice of the passivating mercaptoalcanol compound. A stable sensor system has been developed, enabling a reproducible detection of 25mer target DNA in the low nanomolar range. After hybridization, a sensor regeneration can be reached with deionized water by adjustment of effective convection conditions, ensuring a sensor reusability. By investigations of longer targets with overhangs exposed to the solution, we can demonstrate applicability of the impedimetric detection for longer ssDNA. However, a decreasing charge transfer resistance change (ΔRct) is found by extending the overhang. As a strategy to increase the impedance change for longer target strands, the position of the recognition sequence can be designed in a way that a small overhang is exposed to the electrode surface. This is found to result in an increase in the relative Rct change. These results suggest that DNA and consequently negative charge near the electrode possess a larger impact on the impedimetric signal than DNA further away.}, language = {en} } @masterthesis{Riederer2023, type = {Bachelor Thesis}, author = {Riederer, Estella Charlotte}, title = {ITFS : Redesign des Erscheinungsbildes des Internationalen Trickfilm-Festival Stuttgart}, publisher = {FH Aachen}, address = {Aachen}, pages = {111 Seiten}, year = {2023}, abstract = {Film ab!

One of the main problems is the fluctuating supply of wind and solar energy. Here biogas plants provide a solution, because a demand-driven supply is possible. Before running such a plant, it is necessary to simulate and optimize the process. This paper provides a new model of a biogas plant, which is as accurate as the standard ADM1 model. The advantage compared to ADM1 is that it is based on only four parameters compared to 28. Applying this model, an optimization was installed, which allows a demand-driven supply by biogas plants. Finally the results are confirmed by several experiments and measurements with a real test plant.}, language = {en} } @article{RiemerSchrothSchuetzetal.2000, author = {Riemer, A. and Schroth, P. and Sch{\"u}tz, S. and Hummel, Hans E. and L{\"u}th, H. and Kohl, C.-D. and Sch{\"o}ning, Michael Josef}, title = {The future of fire detection: Biological sensors? - Die Zukunft der Brandgassensorik: Biologische Sensoren?}, series = {Gassensorik in der Brandmeldetechnik : [VdS-Fachtagung, am 15. und 16.
