  Quantum dots have made it possible to substantially increase color quality in LCD displays. However, these cadmium-based nanocrystals have proven to be harmful to the environment. Fraunhofer researchers are working together with an industry partner to develop a promising alternative: quantum dots based on indium phosphide.

Nano-supercapacitors for electric cars
Press Release 2014-07-01
Development of nano-material based supercapacitors © Fraunhofer IPA   Innovative nano-material based supercapacitors are set to bring mass market appeal a good step closer to the lukewarm public interest in Germany. This movement is currently being motivated by the advancements in the state-of-the-art of this device. Electric cars are very much welcomed in Norway and they are a common sight on the roads of the Scandinavian country, in contrast to the situation in Germany.

Testing smart plastics in real time
Press Release 2013-11-04
Sensor system to test the composition of plastics enriched with nanoparticles © Fraunhofer ICT   Nano additives can make plastics scratch and flame proof, or give them antibacterial properties. For this to work, the particle distribution within the plastic compound must be absolutely correct. A new device is now able to test the distribution in real time. "onBOX" uses a sensor system to test the composition of plastics enriched with nanoparticles. The unit is mounted directly onto the mixing plant, and is able to monitor particle distribution.

Touchscreens Made of Carbon
Press Release 2011-01-27
Touchscreens Made of Carbon   Touchscreens are in – although the technology still has its price. The little screens contain rare and expensive elements. This is the reason why researchers at Fraunhofer are coming up with an alternative display made of low-priced renewable raw materials available all over the world. The researchers are presenting touchscreens that contain carbon nanotubes at the nano tech 2011 fair in Tokyo from February 16-18.

Fast sepsis test can save lives
Research News December 2010
Fast sepsis test can save lives   Blood poisoning can be fatal. If you suffer from sepsis, you used to have to wait as much as 48 hours for laboratory findings. A new diagnostic platform as big as a credit card will now supply the analysis after as little as an hour. This system is based on nanoparticles that are automatically guided by magnetic forces.

Plastics and nanoparticles – the perfect combination
Research News October 2010
Plastics and nanoparticles – the perfect combination   These days, plastic components are vital to many fields of industry – lightweight construction, automobile manufacturing and electrical engineering, to name but a few. Now researchers have found ingenious ways to combine plastics with nanoparticles and endow them with new properties. Thanks to these innovative materials, aircraft could in future be better protected against lightning strikes.

Paving slabs that clean the air
Research News August 2010
Paving slabs that clean the air   The concentrations of toxic nitrogen oxide that are present in German cities regularly exceed the maximum permitted levels. That’s now about to change, as innovative paving slabs that will help protect the environment are being introduced. Coated in titanium dioxide nanoparticles, they reduce the amount of nitrogen oxide in the air.

Nanotechnology - midgets with big potential
Research Topics 2010
Nanotechnology - midgets with big potential   Nanotechnology is a cross-section technology concerned with research and construction in very small structures. A nanometer corresponds to a millionth of a millimeter. It is a discipline which offers more potential for innovative applications than any other, as special physical laws apply on the nano-level. The optical, electrical or chemical properties of established materials can be altered completely by manipulation of the nanostructure.

Nanopores make sterile filtration more reliable
Research News July 2010
Nanopores make sterile filtration more reliable   Irregular pores, low flow rates: The plastic membrane filters used in sterile filtration do not always ensure that conditions are really sterile. Filter membranes of aluminum oxide are more reliable – the size of the nanopores can be determined with precision. Even the smallest viruses cannot pass through the membrane.

Perfectly non-reflecting
Research News May 2010
Perfectly non-reflecting   A new nanocoating ensures a perfectly non-reflecting view on displays and through eyeglasses. The necessary surface structure is applied to the polymeric parts during manufacture, obviating the need for a separate process step. The hybrid coating has further advantages: the components are scratch-proof and easy to clean.

Penetration of thin C60 films by metal nanoparticles
Press relase of TU Dortmund, University of Freiburg and Fraunhofer IWM, April 2010
Penetration of thin C60 films by metal nanoparticles   Nanoparticles are recognized as promising building blocks for future applications, however their fixation on surfaces or in a matrix is everything else than a simple task. Now physicists observed that a double layer of spherical C60 carbon-molecules, called fullerenes, is an ideal substrate for these microscopic particles. Their results, recently published in ‘Nature Nanotechnology’, are an important step towards the application of tailor-made nanosystems.
The properties of nanoparticles often differ from those of a large piece made of the same material. By tuning the size and composition of the nanoparticles, one can ‘tailor’ their chemical, optical or magnetic properties, and obtain features different from any bulk material. But for an application of this potential in the fields of catalysis, magnetic storage technology or optoelectronics, one has to fix the nanoparticles on surfaces or in matrixes.

  Kohlenstoff-Nanoröhren (Carbon Nanotubes, kurz CNT) gehören zu den neuen Nanomaterialien mit einem breiten Anwendungspotenzial. Ihre außergewöhnlichen Eigenschaften – extreme Zugfestigkeit, hohe elektrische Leitfähigkeit und das geringe Gewicht – machen diese winzigen Röhrchen aus Graphit für verschiedenste Produkte interessant. Einige Untersuchungen weisen jedoch darauf hin, dass bestimmte Nanotubes mit speziellen Eigenschaften ähnlich krebsauslösend sein könnten wie Asbestfasern. Um potenzielle Risiken für den Menschen auszuschließen, fördert das Bundesministerium für Bildung und Forschung (BMBF) nun den Forschungsverbund CarboTox für drei Jahre mit rund 1,25 Millionen Euro.

Production of large quantities of single wall carbon nanotubes
Innovation cluster "nano for production" with participation of IWS Dresden
Transmission electron micrograph of single wall carbon nanotubes
  Carbon nanotubes show a number of interesting properties such as high strength, very good thermal and electrical conductivity, and interesting optical properties. Only small quantities of carbon nanotubes added to composite materials can open completely new functionalities for the matrix material while simultaneously maintaining the conventional matrix properties and keeping established production lines unchanged.
