SiMoNa optimiert organische Leuchtdioden

Organische Leuchtdioden werden immer mehr Anwendungen erobern und neue Moeglichkeiten in Design und Funktion eroeffnen. Wissenschaftler am Institut fuer Nanotechnologie (INT) des KIT haben nun eine Simulationsloesung zur zeit- und kostenguenstigen Optimierung von OLEDs entwickelt. Mit "SiMoNa" lassen sich Materialeigenschaften gezielt verbessern sowie geeignete Farbstoffmolekuele designen und patentieren.

Particle trap paves way for personalized medicine

A team led by Yale University researchers has proven that isolating individual charged particles, like DNA molecules, is indeed possible using a method called "Paul trapping", which uses oscillating electric fields to confine the particles to a space only nanometers in size.

Novel man-made material could facilitate wireless power

Electrical engineers at Duke University have determined that unique man-made materials should theoretically make it possible to improve the power transfer to small devices, such as laptops or cell phones, or ultimately to larger ones, such as cars or elevators, without wires.

Reusable template for the production of nanowires

Scientists from Argonne's Center for Nanoscale Materials's Nanofabrication Group, working with users from the University of Wisconsin-Stevenson Point, discovered a fast, simple, scalable technique for solution-based, electrochemical synthesis of patterned metallic and semiconducting nanowires from a reusable, nonsacrificial, ultrananocrystalline diamond (UNCD) template.

Droplets for detecting tumoral DNA

It will perhaps be possible, in the near future, to detect cancer by a simple blood or urine test. In fact, biologists from CNRS, Inserm, Paris Descartes and Strasbourg universities have developed a technique capable of detecting minute traces of tumoral DNA present in the biological fluids of patients suffering from cancer. The method consists in carrying out ultra-sensitive molecular analyses in microscopic droplets.

Large two-dimensional molecular crystals promising for organic electronics

One of the most striking properties of graphene is arguably its two-dimensionality. The remarkable electronic behavior realized by this two-dimensionality has prompted researchers to try and form similar two-dimensional sheets from other materials. Wenping Hu and colleagues from the Beijing National Laboratory for Molecular Sciences in China have now succeeded in growing two-dimensional crystals of an organic semiconductor on large scales and on various types of substrate with a view to developing advanced organic electronic devices.
