Plastic electronics hold the promise of cheap, mass-produced devices. But plastic semiconductors have an important flaw: the electronic current is influenced by "charge traps" in the material. These traps, which have a negative impact on plastic light-emitting diodes and solar cells, are poorly understood.
Wie macht sich Quantenphysik im täglichen Leben bemerkbar? Dadurch, dass Materialeigenschaften eng mit den quantenphysikalischen Wechselwirkungen zwischen Atomkernen und Elektronen verknüpft sind, was auch als 'chemische' Bindung bezeichnet wird.
Researchers from the University of Toronto and King Abdullah University of Science & Technology have made a breakthrough in the development of colloidal quantum dot (CQD) films, leading to the most efficient CQD solar cell ever.
The idea to launch Nanotechitaly was based on the awareness that even if activity and interest for nanotechnology in Italy is quite strong and involves considerable resources both in the public research and industry, there wasn't an high level Conference on nanotechnology dealing with application and technology transfer.
A tiny vibrating cantilever sensor could soon help doctors and field clinicians quickly detect harmful toxins, bacteria and even indicators of certain types of cancer from small samples of blood or urine.
Although scientists do not have all the information necessary for detailed risk assessment, several factors demonstrate the need to pursue the necessary research and, in the meantime, to take prudent steps to control exposures.
Just as radio antennas amplify the signals of our mobile phones and televisions, the same principle can apply to light. For the first time, researchers from CNRS and Aix Marseille Universite have succeeded in producing a nanoantenna from short strands of DNA, two gold nanoparticles and a small fluorescent molecule that captures and emits light.
A novel X-ray microscope at DESY offers the world's sharpest X-ray vision: Thanks to the extraordinary brilliance of DESY's X-ray source PETRA III, this microscope is able to resolve details as small as ten nanometers.
