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 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.
