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.
Researchers have developed nanoparticles that not only bypass the body's defence system, but also find their way to the diseased cells. This procedure uses fragments from a particular type of antibody that only occurs in camels and llamas.
Using a state-of-the-art microscope and new methods in image processing, a multi-institutional team of researchers has devised an inventive way to measure the positions of single atomic sites in materials more precisely than ever before.
Researchers at the Max Planck Institute of Quantum Optics are working on ultrafast interactions of electron collectives in solid states with light, processes which take place within femtoseconds to attoseconds.
Researchers have demonstrated a technique for detecting and controlling ultrahigh frequency sound waves at the nanometer scale. This represents an advance towards next generation ultrasonic imaging with potentially 1,000 times higher resolution than today's medical ultrasounds.
