A single molecule bridging a "broken" single-walled carbon nanotube (CNT) is barely visible through a powerful scanning electron microscope, but the precisely assembled system can act as a functional solid-state electronics device. These CNT-molecule-CNT junctions have been developed only in the past few years, and measuring their optical characteristics has been a difficult task. In a new study, scientists have observed for the first time that the molecule between the nanotubes can emit light due to an electric current passing through it, a phenomenon called electroluminescence.
The supermassive black hole is 40 million times as massive as the sun and powers a quasar that existed 700 million years after the Big Bang.
Vision Pro is here and it’s a surprisingly capable device. Apple has also loaded the headset with a ton of options and features that aren’t obvious at first glance.
Engineers expect to lose contact with the private US moon lander Odysseus on Tuesday, cutting short the mission after its sideways touchdown last week.
