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.
Scientists are using this special gas as a model system to more easily study the largely unknown mechanism of the superfluid phase transition in 2D structures. The researchers hope to gain new insight into the so-called room-temperature superconductor, a hypothetical material that does not require cooling to achieve lossless conduction of electricity.
Researchers have for the first time visualized the growth of nanoscale chemical complexes in real time, demonstrating that processes in liquids at the scale of one-billionth of a meter can be documented as they happen.
