Journal ArticleDOI
A new dynamic hydrogen reference electrode for applications in thin-film sensor systems
Thomas Nann,Gerald Urban +1 more
TL;DR: In this paper, the realization and applicability of a new dynamic hydrogen reference electrode (DHRE) within an electrochemical microcell for sensor applications is reported, which is fabricated in thin-film technology and fixed within a flow-through device.
Journal ArticleDOI
A lab-on-a-chip for free-flow electrophoretic preconcentration of viruses and gel electrophoretic DNA extraction
TL;DR: This work demonstrates the complete microfluidic preparation of amplifiable virus DNA from dilute specimens and demonstrates a detection limit of ∼1 PFU ml-1 (∼0.02 DNA copies per μl) for the detection of bacteriophage PhiX174 by PCR.
Journal ArticleDOI
Simulation and fabrication of a 2D-flow sensor for simultaneous fluid characterization
A.S. Cubukcu,Gerald Urban +1 more
TL;DR: In this article, an enhanced flow sensor is developed at IMTEK to enable simultaneous fluid characterization and flow velocity measurement, which is necessary to measure flow rates accurately by thermal means in cases where fluid properties fluctuate in time.
Journal ArticleDOI
Ceria-zirconia Mixed Oxide Prepared through a Microwave-assisted Synthesis for CO2 Sensing in Low Power Work Function Sensors
TL;DR: In this article, the sensitivity towards CO2 of pure ceria, zirconia and a Ce-Zr mixed oxide were tested in a Kelvin Probe setup and a high work function response in humid air was observed for all compositions, the mixed oxide exhibiting the best sensing characteristics.
Journal ArticleDOI
In Situ Mapping of H2, O2, and H2O2 in Microreactors: A Parallel, Selective Multianalyte Detection Method.
Sebastian Urban,Benedikt J. Deschner,Laura L. Trinkies,Jochen Kieninger,Manfred Kraut,Roland Dittmeyer,Gerald Urban,Andreas Weltin +7 more
TL;DR: In this article, the authors propose a parallel monitoring of a microreactors to determine local concentrations of the analytes in state-of-the-art micro-reactors, which is essential for the development of optimized and safe processes.
