Researchers designed a novel metamaterial that buckles on demand. Small structural variations in the material single out regions that buckle selectively under external stress, whereas other regions remain unchanged.
Tyndall National Institute in Ireland, CEA-Leti in France and imec in Belgium, leading European nanoelectronics institutes, have entered into a collaborative open-access project called ASCENT (Access to European Nanoelectronics Network), to mobilise European research capabilities like never before.
Chemists have developed a new class of organic luminescent materials through the targeted introduction of boron atoms into the molecular structures. The compounds feature an intensive blue fluorescence and are therefore of interest for use in organic light-emitting diodes.
Experimental physicists have successfully cooled molecules in a gas of sodium potassium to a temperature of 500 nanokelvins - just a hair above absolute zero. They found that the ultracold molecules were relatively long-lived and stable, resisting reactive collisions with other molecules. The molecules also exhibited very strong dipole moments.
A new reveals that designers of metallic-glass-based nanodevices must account for tiny flaws in alloy frameworks to avoid unpredictable catastrophic failure. Understanding how nanoscale metallic glass fractures and fails when subjected to external stress is critical to improving its reliability in devices and composites.
Scientists have developed a fast, simple process for making platinum 'nano-raspberries' - microscopic clusters of nanoscale particles of the precious metal. The berry-like shape is significant because it has a high surface area, which is helpful in the design of catalysts.
It can analyze the chemical composition of substances and detect biological objects, such as viral disease markers, which appear when the immune system responds to incurable or hard-to-cure diseases, including HIV, hepatitis, herpes, and many others.
Engineers built a synchronous computer that operates using the unique physics of moving water droplets.The work combines expertise in manipulating droplet fluid dynamics with a fundamental element of computer science - an operating clock.
Systems allowing label-free molecular-level detection are expected to have enormous impact on biochemical sciences. Research focuses on materials and technologies based on exploiting the coupling of light with electronic charge oscillations, the so-called localized surface plasmon resonances, in metallic nanostructured antennas.
