It’s not quite the T-1000 pulling itself together after being blown apart, but it’s pretty much the same idea. For the first time in history, scientists have observed the self-assembly of nanoparticles in real-time.
Each of the particles seen in the video above measures a scant 12 nanometers across. To put that in perspective, you’d have to divide the thin side of a dime by a thousand, and then take one of those slivers and divide it by a thousand again. That’s roughly one nanometer.
That’s mighty, mighty tiny — so tiny in fact that the researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory had to use a transmission electron microscope located at the Center for Nanoscale Materials to capture the quick movement of the nanoparticles.
To get the tiny bits to re-assemble, the researchers put the gold nanoparticles into a small liquid pouch and covered it with a positively charged coating. When it was exposed to an intense beam of electrons, an effect was created where “hydrated” electrons attracted the positively charged nanoparticles — but it was an effect that was gradually reduced over time. Once freed from these forces, the nanoparticles were able to jump around and stick together in long chains.
Nelson Mandela Family Finally Gives Up Charade and Admits Mandela Dead 2013 12 12 Funeral was planned a year ago
The Nelson Mandela family has finally given up their charade and admitted that Nelson Mandela is dead by announcing today that the former leader of South Africa is no longer with us.
The charade began in June of 2013, and Guardian Express has maintained Mandela has been deceased since we were informed of his passing in ...
Scientists Identify a Piece of the Planet Mercury for the First Time in Human History 2013 12 12 Talk about a precious stone — the largest piece of the only known meteorite from the planet Mercury has found its way to Yale, where it is now on display at the Peabody Museum of Natural History.
Known as NWA 7325, the fist-size, greenish space rock is a rarity among rarities: there just aren’t many verified planetary meteorites. Scientists know ...
US general who opened Guantanamo prison says shut it down 2013 12 12
The US general who opened the notorious US-run Guantanamo prison says it was a mistake and it should be shut down because the prison complex "validates every negative perception of the United States."
"In retrospect, the entire detention and interrogation strategy was wrong," Marine Major General Michael Lehnert wrote in the Detroit Free Press on Thursday.
Lehnert was the first commander of ...
BioSuit: The Future of Space Gear 2013 12 12 New materials and designs could allow outer-space travelers to move more freely.
One day, moving around in outer space—and walking on Mars—could become a whole lot more comfortable for astronauts, thanks to the innovative techniques being developed by an aeronautics professor at MIT.
“The BioSuit—the one that gets a lot of media coverage—is a concept no one has seen before, and we ...
Cassini spies mysterious object named ’Peggy’ at edge of Saturn’s rings 2013 12 12
Nasa’s Cassini spacecraft has spotted an object located right at the edge of Saturn’s A ring that is confounding scientists. Its name? Peggy.
This strange something was spotted by accident on 15 April when Cassini’s cameras were aimed at a tiny moon named Prometheus that orbits just inside another of Saturn’s rings. A member of the mission’s imaging team, astronomer Carl ...
