Processes on the atomic scale can only be described accurately by using the laws of quantum mechanics. Physicists have now succeeded for the first time to completely determine the state of such a quantum mechanical system in experiments.
What links legendarily sharp Damascene swords of the past with flexible electronics and high-performance electrical wiring of the future? They all owe their remarkable properties to different structural forms of carbon.
The EU NanoSafety Cluster has released the 2014 edition of its anual compendium that documents the status of important EU-funded projects on nanomaterial toxicity and exposure monitoring, integrated risk management, research infrastructure and coordination and support activities as well as regulatory-focussed research on nanosafety.
Progress in the field of nanotechnology can only be achieved, if analytical methods for the characterization of nanostructures continuously improve. Due to the structures' small size visible light cannot be utilized for nanoanalytical techniques. In point of fact, microscopic methods with electron waves or X-rays must be applied here, as the wavelengths, they work with, are small enough. Multilayer Laue lenses (MLL) offer a most promising approach to developing highest resolution X-ray optics.
What mode of action do nanomaterials ingested via food have in liver and intestine? Which factors determine their toxicity? Due to the large number of different nanomaterials, it is hardly possible to test every one for its toxic properties. For this reason, specific properties for the classification of nanomaterials are to be examined within the scope of the Franco-German research project SolNanoTox, which began on 1 March 2014.
Using a newly developed imaging method, researchers show that thin-film organic semiconductors contain regions of structural disorder that could inhibit the transport of charge and limit the efficiency of organic electronic devices.
Brightly-colored, iridescent films, made from the same wood pulp that is used to make paper, could potentially substitute traditional toxic pigments in the textile and security industries. The films use the same principle as can be seen in some of the most vivid colors in nature, resulting in colors which do not fade, even after a century.
Nanotechnology, optics and photovoltaic energy are among the fields that can benefit from advances in knowledge on semiconductor nanowire systems. Researchers have succeeded to prove, for the first time, the accumulation of high electron mobility gases in multilayer nanowires from a technique called 'remote doping'.
Lawrence Livermore National Laboratory recently received $5.6 million from the Department of Defense's Defense Advanced Research Projects Agency (DARPA) to develop an implantable neural interface with the ability to record and stimulate neurons within the brain for treating neuropsychiatric disorders.
The quantum tunnel effect manifests itself in a multitude of well-known phenomena. Experimental physicists have now directly observed quantum particles transmitting through a whole series of up to five potential barriers under conditions where a single particle could not do the move.
