Chemists have determined that a fluid that behaves similarly to water in our day-to-day lives becomes as heavy as honey when trapped in a nanocage of a porous solid, offering new insights into how matter behaves in the nanoscale world.
An international team of physicists has observed spontaneous mechanical buckling in freestanding graphene using scanning tunneling microscopy, indicating it has potential to be a new electronic power source.
Die vielfaeltigen Aktivitaeten zur Nanotechnologie werden ressortuebergreifend gebuendelt und auf die zentralen gesellschaftlichen Herausforderungen wie Klimawandel, Energiewende, Digitalisierung, Gesundheit, Mobilitaet und Industrie 4.0 ausgerichtet.
Scientists have demonstrated that when a topological insulator - a material that conducts electricity on the surface but not in the interior - with magnetic properties is exposed to light, the angles of the rotation of light polarization driven by the magneto-optical effect show the universal values determined by quantum mechanics.
Engineers happen upon a way to stop the movement of the colorful eddies on the surface of soap bubbles. The results are works of art that could lead to stable engineered foams for medical treatments, personal products and food.
Engineered surfaces add value to the things we use, providing extra layers of safety, easing their operation, preserving their quality or adding utility. Materials researchers are looking to greatly improve on the concept with a method of micron-scale surface chemical patterning that can not only decrease time and money spent in their manufacture, but also add versatility to their design.
Fabrics that can generate electricity from physical movement have been in the works for a few years. Now researchers have taken the next step, developing a fabric that can simultaneously harvest energy from both sunshine and motion.
A new study has shown water can serve a previously undiscovered role to help micelles coalesce to spontaneously form long fibers. The study could help scientists to understand how light-harvesting molecules are incorporated into the micelle fiber as it assembles, which would be a key step to understanding some forms of artificial photosynthesis.
Researchers, who began exploring thin-film tunable dielectrics using sputtered material nearly two decades ago, are now trying to leverage advanced and scalable materials deposition techniques like molecular beam epitaxy (MBE) to create tunable, high-frequency integrated circuits and devices with high-quality materials that are comparable to modern semiconductor technology.
Researchers have discovered a method that paves the way for a new generation of magnetic sensors. Their procedure can be used to greatly extend the functionality of such sensors, which is limited when conventional production methods are used, so that sensors can now be individually tailored to a wide variety of new applications.
