FoBt Sensor - Faseroptischer Betauungssensor erkennt feuchte Oberflächen

29.05.2012
Anhaltende und nicht erkannte Feuchtigkeit führt zu

erheblichen Qualitätsverlusten von Produkten. Um die Qualität von Produkten zu sichern, braucht man im Zuge der Lebensdauerprüfung genaue Aussagen über deren Betauungsempfindlichkeit. Ein neuartiger Betauungssensor der Hochschule Niederrhein kombiniert die

Detektion der Wasserkondensation an Oberflächen mit einer quantitativen Bestimmung des Betauungsgrades. Möglich wird das durch die Anwendung des faseroptischen Sensorprinzips. Zugeschnitten auf die Anforderungen aus der Praxis wurde am Institut für angewandte Nano- und optische Technologien der Hochschule Niederrhein ( iNano ), Krefeld, ein neuartiger Betauungssensor entwickelt. Hierbei findet ein hochempfindliches faseroptisches Sensorprinzip Anwendung, das die Detektion der Wasserkondensation an Oberflächen mit einer quantitativen Bestimmung des Betauungsgrades kombiniert.

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Im Focus: Successful Mechanical Testing of Nanowires

With innovative experiments, researchers at the Helmholtz-Zentrums Geesthacht and the Technical University Hamburg unravel why tiny metallic structures are extremely strong

Light-weight and simultaneously strong – porous metallic nanomaterials promise interesting applications as, for instance, for future aeroplanes with enhanced...

Im Focus: Virtual Reality for Bacteria

An interdisciplinary group of researchers interfaced individual bacteria with a computer to build a hybrid bio-digital circuit - Study published in Nature Communications

Scientists at the Institute of Science and Technology Austria (IST Austria) have managed to control the behavior of individual bacteria by connecting them to a...

Im Focus: A space-time sensor for light-matter interactions

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.

The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...

Im Focus: A transistor of graphene nanoribbons

Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."

Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
