Researchers observe Floquet states in colloidal nanoplatelets driven by visible pulses

Posted by in category: quantum physics

Solution-processed semiconductor nanocrystals are also called colloidal quantum dots (QDs). While the concept of size-dependent quantum effects had long been known to physicists, a sculpture of the theory into real nanodimensional objects remained impossible till the discovery of QDs. The size-dependent colors of QDs are essentially naked-eye, ambient-condition visualizations of the quantum size effect.

“Both TOI-1408 b and TOI-1408 c are incredibly close to their parent star compared to the planets in our solar system,” research lead author Judith Korth of Lund University told Space.com. “Imagine our solar system, but instead, Jupiter is orbiting very close to the sun nearly every four days, one-twentieth of the period of Mercury.

This is already very close to the star, and still, we detected another planet even closer to the star that interacts strongly with its big neighbor, causing their orbits to wobble in ways we’ve never seen before.

This engine has travelled 200 years in time: It runs on a fuel that Edison predicted and Musk wants to develop

Posted by in category: energy

This engine was predicted by Edison 200 years ago, and now has been created: It’s neither electric nor hydrogen, but something miles ahead.

Houston now has its first grid-scale battery storage facility

Posted by in categories: energy, space

Jupiter Power, an Austin-based energy developer, owns and operates the project at Hiram Clarke Road and U.S. 90 at the site of the former H.O. Clarke gas-fired power plant. It’s a 200-megawatt facility, enough to power 50,000 Texas homes during the hottest summer days, with the ability to discharge power at maximum capacity for two hours.

On any given day, the Houston area must import about 60% of its needed electricity from other parts of the state where power plants are more plentiful. This often results in a phenomenon known as congestion: Low-cost electrons are clogged on power lines into Houston much like commuters on the highway during rush hour, which raises the wholesale cost of electricity in the region. These wholesale price spikes are initially paid by retail electric providers and can eventually be passed onto consumers.

Spacecraft zooms by the moon, captures sci-fi footage

Posted by in category: space

A spacecraft just sped between Earth and the moon, en route to the deep solar system.

And as it zipped by the cratered lunar orb on Aug. 19, the European Space Agency’s Juice mission snapped views of the 21st-century space scene.

“Sometimes the journey is just as worthy as the destination,” ESA director Josef Aschbacher posted online. “As humankind embarked on the monumental first lunar-Earth flyby, @ESA’s Jupiter Icy Moons Explorer (Juice) mission captured a breathtaking glimpse of our natural satellite.”
