Nanoparticles have the potential to revolutionize the medical industry, but they must possess a few critical properties. First, they need to target a specific region, so that they do not scatter throughout the body. They also require some sort of sensing method, so that doctors and researchers can track the particles. Finally, they need to perform their function at the right moment, ideally in response to a stimulus. Scientists are trying to develop new particles with unprecedented properties that still meet these requirements.
Nanoparticles can emit light into ultra-thin glass fibres. Physicists have now managed to select the direction of the light using an unusual kind of coupling between spin and the direction of propagation.
Physicists have developed a novel microscope that allows them to record slow-motion movies of tiny nanostructures with groundbreaking time resolution - faster even than a single oscillation cycle of light. With their new microscope they have directly imaged the super-fast motion of electrons.
Researchers have demonstrated a novel automated fabrication process consisting of a three-step sol-gel extrusion, structure freezing and drying, and mechanical drawing process which results in production of highly aligned polymer films.
Fullerenes seemed to many an excellent candidate for nano-bearings. Unfortunately, the results so far have been conflicting, calling for further studies. Through a series of computer simulations, scientists uncovered the reason for the experimental discrepancies and shed light on the true potential of this material.
NIOSH and CNSE will work together to advance research and guidance for occupational safety and health in the nanoelectronics industry and other settings where workers are potentially exposed to engineered nanomaterials.
Researchers have discovered a new way to simultaneously image both the ferromagnetic and the ferroelectric domain structures of multilayer devices in which a ferromagnetic film is grown on a ferroelectric substrate. These structures have attracted significant recent interest due to their ability to efficiently use voltage to change the magnetization in low-energy magnetic devices.
Nanostructures of virtually any possible shape can now be made using a combination of techniques. Especially the unique properties of so-called perovskites can be exploited further: their crystal structure is not influenced by the process.
