The premier event in the
field of chemical sensing.
Our research in the DFG priority programme Ferroic Cooling provided the cover art for the April 2018 issue of the MRS Bulletin with a focus on Caloric Effects in Ferroic Materials.
In the issue, our research was covered in the article "High-performance elastocaloric materials for the engineering of bulk- and micro-cooling devices" co-authored by Jan Frenzel, Gunther Eggeler (both Bochum), Eckhard Quandt (Kiel), Stefan Seelecke (Saarbrücken) and Manfred Kohl (Karlsruhe).
The cover art shows an image from Marvin Schmidt´s PhD thesis entitled: "Elastokalorisches Kühlen mit Ni-Ti-basierten Formgedächtnislegierungen: Thermodynamische Analyse, experimentelle Untersuchungen, Prozessoptimierung" with our elasto-caloric cooling demonstrator: a NiTi ribbon is used to transport heat from the heat source (blue) to the heat sink (red) to achieve a significant temperature difference after only a few cooling cycles.

Low-cost sensor technologies are gaining increasing interest for monitoring of air quality, both in the outside air and indoors. Sensor technologies can provide comprehensive information concerning a wide range of pollutants with high spatial and temporal resolution. They thereby offer the basis for novel environmental information services, i.e. green routes through cities for bikers and joggers. However, the data quality and reliability of these sensors as well as systematic integration with fixed monitoring stations and modeling approaches remain challenging.
The Special Issue will cover a range of topics addressing modern sensor technologies, test, validation and calibration as well as practical applications including multisensor integration, uses for model validation, data fusion and data assimilation, but also for supporting environmental information services and citizen science goals. We target high quality papers on the latest technological developments as well as examples of field studies using low-cost air pollution sensors of various types and for numerous applications in ambient as well as indoor environments.

Our recent paper "Highly Sensitive and Selective VOC Sensor Systems Based on Semiconductor Gas Sensors: How to?" was selected as cover story for the March 2017 issue of the journal ENVIRONMENTS. The paper provides an overview over our work on low-cost VOC sensors for einvironmental monitoring and is available open access.
Smart microsensor systems for VOCs, including critical low-threshold pollutants such as benzene, can allow monitoring with high spatiotemporal resolution. A systematic approach for low-cost sensor systems is presented by combining dynamic operation for increased selectivity and sensitivity with a novel pre-concentrator concept. Advanced gas test systems allow testing and evaluation in realistic complex matrices, while a strategy is proposed for cost-efficient factory and on-site calibration.
The cover art shows the model for temperature cycled operation (TCO) of metal oxide gas sensors, our novel approach for integrating pre-concentration and sensors in a miniaturized package and the results obtained for benzene quantification using PLSR with an uncertainty of less than 1 ppb.

Das von der Deutschen Bundesstiftung Umwelt (DBU) geförderte Projekt SUSmobil "Befähigung und Begleitung von Schülern zur Durchführung von Umweltstudien mit Smartphone und mobiler Messtechnik – Bewertung von Luftqualität und Abgasen durch Erfassung umwelt- und gesundheitsrelevanter Schadstoffe" ist am 01. Juli 2017 gestartet, die Projektlaufzeit beträgt drei Jahre.
Gemeinsam mit unseren Projektpartnern TU Kaiserslautern, Fachbereich Physik, AG Didaktik der Physik, Prof. Dr. Kuhn und Schülerforschungszentrum Saarlouis, Benjamin Brück wollen wir Schülerinnen und Schülern moderne Methoden der Umweltmesstechnik – insbesondere auf Basis von Smartphones/Tablets verknüpft mit aktuellen Sensorlösungen – nahebringen. Anschließend werden diese zur Entwicklung eigener Fragestellungen und Durchführung von Studien im Bereich der Umweltmesstechnik angeregt. Die Methoden werden in Schülerlaboren in enger Zusammenarbeit zwischen Fachwissenschaftlern, Fachdidaktikern und Lehrkräften entwickelt und erprobt sowie schließlich über Schülerforschungszentren und Einbettung in den Schulunterricht einem größeren Kreis zugänglich gemacht.
