‘Electron Liquid’ Created at Room Temperature

In conventional electronic devices, electricity requires the movement of electrons (blue spheres) and their positive counterparts, called holes (red spheres), which behave much like the gas molecules in our atmosphere. Although they move rapidly and collide infrequently in the gas phase, electrons and holes can condense into liquid droplets akin to liquid water in devices composed of ultrathin materials.

A team of physicists at the University of California, Riverside, has produced the first ‘electron-hole liquid’ at room temperature. In conventional electronic devices, electricity requires the movement of electrons (blue spheres) and their positive counterparts, called holes (red spheres), which behave much like the gas molecules in our atmosphere. Although they move rapidly and collide infrequently in the gas phase, electrons and holes can condense...

From a great distance, our Milky Way Galaxy would look like a thin disk of stars that orbits once every few hundred million years around its central region, where hundreds of billions of stars provide the gravitational ‘glue’ to hold it all together. But this pull of gravity is much weaker in the Galaxy’s far outer disk. There, the hydrogen atoms making up most of the Milky Way’s gas disk are no longer confined to a thin plane, instead they give the disk an S-like, or warped, appearance. Image credit: Xiaodian Chen.

The two Moon-exploring crew men of the Apollo 14 lunar landing mission photographed and collected the large rock pictured just above the exact center of this picture. The rock, casting a shadow off to the left, is the lunar breccia 14321. It lies between the wheel tracks made by the modular equipment transporter (MET) or rickshaw-type portable workbench. A few prints of the lunar overshoes of the crew members are at the left. This photo was made near the boulder field near the rim of Cone Crater. Image credit: NASA.

A 30,000 light-year region from the Renaissance Simulation centered on a cluster of young galaxies that generate radiation (white) and metals (green) while heating the surrounding gas. A dark matter halo just outside this heated region forms three supermassive stars (inset) each over 1,000 times the mass of our Sun that will quickly collapse into massive black holes and eventually supermassive black holes over billions of years.
