New ultra-thin glass is just two atoms thick, earns Guinness World Record

A new record for the world’s thinnest sheet of glass has been set, and it comes in at just two atoms thick. The ultra-thin glass, now recognized by the Guinness Book of World Records, was an accidental discovery by scientists at Cornell University and Germany’s University of Ulm. As they were working to produce pure graphene, the researchers noticed a formation of “muck,” but closer analysis revealed a glass layer composed of silicon and oxygen. In other words, this major discovery was something of a stroke of luck. Scientists suspect that an air leak prompted a reaction between copper foils being used for the graphene work and a quartz furnace.

And despite the glass pane’s barely-there size, it’s providing scientists with a wealth of…

Oh Cool, IBM Also Made Some Star Trek Art With Atoms

star-trek-atom-art-1.jpg

Bear in mind the other day’s stop movement video that IBM made using individual atoms as pixels!.?. !? Well it ends up they also made some Star Trip art while they went to it. Why? Not sure, presumably since there’s a brand-new movie coming out. That or they simply really like Star Trip. Or maybe a crazed Trekkie with among those horrifying looking Klingon struggle swords was threatening them bodily damage if they didn’t. THE POSSIBILITIES ARE ENDLESS. For lunch today? The possibilities are extremely limited. It’s looking like a Carnation Instant Morning meal or run the risk of attempting the cottage cheese that ended a week back. I’m kind of afraid to look at it however due to the fact that I enjoy cottage cheese and if it’s musty I’ll have a tough time getting the image from my head the next time I go to the grocery store wishing to purchase more. Now pay attention: you may not such as home cheese, but do not act like you have no idea what I’m discussing. Shared experiences like this– that’s exactly what makes us all human.

Arrived the jump for a Vulcan salute and a profile of the USS business that’s just a nanometer tall. You’re not gonna fit a lot of staff on a ship that size.

Teensy: Stop Motion Made Using Single Atoms As Pixels

ibm-single-atom-stop-motion.jpg

This is a short stop motion video from IBM that they produced using SINGLE ATOMS as individual pixels. Do you understand how small an atom is? No? Well think of a bouncy ball. Now think of a SUPER F \*\*\* ING TEENY bouncy ball. That’s how small an atom is provided you imagined a bouncy ball small enough. The atoms in the video have actually been multiplied 100-million times. The pubic hair I plucked and looked at under a microscope in 10th grade biology course? I think that was 50x. My laboratory partner informed on me too which is exactly why she got SHOCK DISSECTED FROG COMPONENTS in her knapsack the following semester. Do not tinker science, Stephanie!

Arrived the jump for the short in addition to a making-of video if you’re really into science and not simply fabricating it due to the fact that science is supposed to be so cool right now. You know who you are.

Dances with atoms: IBM researchers create a short film using only microscopic particles

Boyatom_large

A group of IBM researchers took a break from studying atomic data storage to work on something a bit more lighthearted: a stop motion movie made entirely out of atoms. The film, aptly named A Boy and His Atom, was created by arranging atoms with a scanning tunneling microscope and then capturing the arrangement as an image, magnified to over 100 million times its actual size. The final result is a brief 242 frames that show a charming story of a boy dancing and playing with an atom. Before its debut today, IBM even had the Guinness World Records verify the short as the “world’s smallest movie.”

IBM is accompanying the film with a series of short videos explaining the technology that was involved in creating it. In the videos, the team…

Extreme closeup! IBM makes ‘world’s smallest movie’ using atoms (video)

DNP IBM

After taking a few shadowy pictures for the scientific world’s paparazzi, the atom is now ready for its closeup. Today, a team of IBM scientists are bypassing the big screen to unveil what they call the “world’s smallest movie.” This atomic motion picture was created with the help of a two-ton IBM-made microscope that operates at a bone-chilling negative 268 degrees Celsius. This hardware was used to control a probe that pulled and arranged atoms for stop-motion shots used in the 242-frame film. A playful spin on microcomputing, the short was made by the same team of IBM eggheads who recently developed the world’s smallest magnetic bit. Now that the atom’s gone Hollywood, what’s next, a molecular entourage?

Researchers capture a single atom’s shadow, has implications for quantum computers

Researchers capture a single atom's shadow, has implications for quantum computers

A very small atom can cast a very large shadow. Well, not literally, but figuratively. Researchers at Griffith University have managed to snap the first image of a single atom’s shadow and, while the dark spot may be physically small, the implications for the field of quantum computing are huge. The team of scientists blasted a Ytterbium atom suspended in air with a laser beam. Using a Fresnel lens, they were able to snap a photograph of the dark spot left in the atom’s wake as the laser passed over it. The practical applications could improve the efficiency of quantum computers, where light is often used to transfer information. Since atoms have well understood light absorption properties, predictions can be made about the depth of a shadow cast, improving communication between the individual atoms performing calculations. The research could even be applied to seemingly mundane and established fields like X-Ray imaging, by enabling us to find the proper intensity levels to produce a quality image while minimizing damage to cells. For more info, check out the current issue of Nature.

Sensitive scales can weigh individual atoms, ensure perfect recipes

Those of you who have navigated beyond using an Easy-Bake Oven will know that weighing out ingredients is a chore. Then again, it’s nothing compared to the sort of balancing that takes place at the Catalan Institute of Nanotechnology, where a team has developed a method of weighing individual protons. Using heated, shortened carbon nanotubes in a vacuum, the scale vibrates at different frequencies depending on what molecules are balanced on top. The Yoctogram-scale will enable scientists to diagnose health conditions by finding differences in mass, identifying elements in chemical samples that only differ at the atomic level and ensuring you never over-flour your batter mix again.

Researchers capture first-ever images of atoms moving inside a molecule

The headline sums it up nicely but really, those photographic acrobatics account for only part of the story. Starting from the beginning, a research team led by Louis DiMauro of Ohio State University used an “ultrafast” laser to knock an electron out of its orbit, which scattered off the molecule as it fell back toward its natural path. That ripple effect you see in that photo up there represents any changes the molecule went through during the quadrillionth of a second that transpired between laser pulses. Yes, that’s the kind of rare, psychedelic shot that’s sure to earn DiMauro and team bragging rights, but the scientists also say this technique could have practical implications for observing — and ultimately manipulating — chemical reactions at an atomic level. Of course, it could be a long time yet before scientists analyze complex proteins in such detail: for the purposes of this experiment, the researchers stuck with simple nitrogen and oxygen molecules, with which chemistry scholars are already quite familiar. In fact, the researchers don’t elaborate at all on specific studies where this technique might be useful, but you might want to hit up the source link nonetheless for some of the more technical details of how they pulled off this experiment in the first place.

IBM stores bits on arrays of atoms, shrinks magnetic storage to the scientific limit

IBM’s Almaden Research Center is filled with some of the best and brightest minds in the world, and its researchers just released new findings that detail how just how far IBM has come in the realm of magnetic storage. Andreas Heinrich is leading the team at Big Blue that figured out how to create atomic storage based on the fact that atoms of ferromagnetic material align their spins in one direction — so the ability to control the spin direction is what’s needed to make such minature memory possible. Heinrich and his crew were able to accomplish the trick by supercooling 12 atoms to four degrees kelvin (-452 fahrenheit), and arranging them using an electron microscope in such a away that nonvolatile storage became possible. As this is only a proof of concept, we won’t be seeing atomic memory at, say, CES any time soon, but you can dig into the deep science behind the breakthrough at the source link below.

This electric wire is four atoms thick, and you thought speaker cable was fiddly (video)

This should come as a great relief to anyone planning a quantum computer self-build: wires still conduct electricity and obey key laws of classical physics even when they’re built at the nanoscale. Researchers at Purdue and Melbourne universities used chains of phosphorus atoms inside a silicon crystal to create a wire that’s just four atoms wide and a single atom high — 20 times smaller than the previous record-holder and infinitely narrower than anything you’d find at Newegg. The video after the break almost explains how they did it.
