Rice Univerity nanodragster rolls on carbon buckeyball wheels, lives life .0005 inch at a time

Drag racing and nanotech seemingly go together like peanut butter and… very small rocks, but that hasn’t stopped a team of researchers at Rice University from creating a microscopic car dubbed a “nanodragster.” Its wheels are buckeyballs, the rear composed of 60 carbon atoms each, while its front wheels are made of p-carborane. This gives the car more grip at the back, meaning it’ll pop wheelies just like a real dragster — though only when running on a road paved with gold. Even then it doesn’t go very fast, just .0005 inches per hour, meaning for those 1,327,000 days it takes to cover a quarter-mile its driver is free.

Nanosys and LG Innotek agree deal for newfangled LED-backlit displays

For the nitty gritty of how Nanosys’ proprietary LED backlighting technology works, check out our earlier coverage here — what you really need to know is that the company promises a significantly wider color gamut from its displays, while reducing power consumption by up to 50 percent. Quantum dot LEDs have shown their faces before, but now there’s the big hulking heft of LG Innotek — LG’s component manufacturing arm — behind what Nanosys is offering, which indicates we might actually see the release of nanotech-infused displays within the first half of this year as promised. The early focus appears to be on mobile phones, which gives us yet another next-gen feature to add to our list of requirements for our next phone. Check out the full PR after the break.

Self-assembling solar cells built using ancient wisdom, modern technology

Alright, so self-assembling electronics are hardly new in and of themselves, and nanoscale tech tends to always come with bombastic promises, but you don’t wanna miss how this latest innovation is built. Two professors from the University of Minnesota have successfully demonstrated a self-assembly technique that arranges microscopic electronic elements in their proper order thanks to the absolute enmity that exists between water and oil. By coating elements with a hydrophilic layer on one side and some hypdrophobic goo on the other, they’ve achieved the proper element orientation, and the final step in their work was the insertion of a pre-drilled, pre-soldered sheet, which picks up each element while being slowly drawn out of the liquid non-mixture. The achievement here is in finding the perfect densities of water and oil to make the magic happen, and a working device of 64,000 elements has been shown off — taking only three minutes to put together. If the method’s future proves successful, we’ll all be using electronics built on flexible, plastic, metal, or otherwise unconventional substrates sometime soon.

Nanosys offers better saturation of LED-backlit displays with nanoscale coating

While we all wait around for larger-sized OLED displays to become feasible for the consumer market, Nanosys has stolen in and demonstrated a new LED coating technique that proposes to radically improve color saturation in LED-backlit screens. Based on standard blue LEDs — the most efficient kind — this works by applying nanoparticles to the light and thereby endowing it with the desired hue. While the nano-coating can make standalone LED lights far richer in color, the real potential is in its deployment in LED-backlit displays, such as those becoming dominant on laptops today. By employing a coated array of blue LEDs instead of the standard white stuff, this can deliver greater color saturation while fitting within the same energy profile of current LED tech. Products boasting Nanosys’ new hotness are said to be coming out later this year, with some appropriate premium slapped on the price for the fancier output.

Quantum batteries are theoretically awesome, practically non-existent

Today’s dose of overly ambitious tech research comes from the physics lab over at the University of Illinois at Urbana-Champaign, in a proposal titled “Digital quantum batteries: Energy and information storage in nano vacuum tube arrays.” It’s like a who’s who of undelivered promises got together and united to form one giant and impossible dream, but it’s one we’d prefer to believe in regardless. Aiming to improve battery performance by “orders of magnitude,” the project’s fundamental premise is that when capacitors — and we’re talking billions of them — are taken to a small enough scale and packed to within 10nm of one another, quantum effects act to prevent energy loss. The projected result is a wonderful world of rapid recharges and storage of up to ten times the energy current lithium-ion packs can hold, as well as the potential for data retention. The only problem? It would take a year just to build a prototype, meaning we can expect market availability somewhere between a score from now and just prior to the underworld morphing into an ice rink.

UCLA nanowire discovery could lead to faster, stronger, smaller electronics

Advancements in silicon-germanium have been going on for years now, but a team at UCLA is convinced that their discovery really is “the next big thing.” For scores now, microchip makers have struggled with miniaturizing transistors as the public at large demands that things get smaller and smaller. Thanks to researchers at the aforesaid university, it’s looking like silicon-germanium nanowires could be the key to making the process a whole lot easier. According to study co-author Suneel Kodambaka, the new nanowires could “help speed the development of smaller, faster and more powerful electronics,” also noting that they’re so small that they can be “placed in virtually anything.” Which is great, because the Adamo XPS is just entirely too pudgy.

Researchers craft all-electric spintronics, vie for guest spot on Mindfreak

Unfortunately for us, we’ve no certified rocket scientist on staff. That said, we’re absolutely convinced that the whiz-kids over at the University of Cincinnati are more than up to the task of improving a science that may or may not actually be useful in real things before 3028. As we continue to hear more about spintronics (described as “transistors that function by controlling an electron’s spin instead of its charge”), a team of UC researchers have stumbled upon a novel way to control an electron’s spin orientation using purely electrical means. In fact, one member calls this discovery the “holy grail of semiconductor spintronics,” though we’re guessing it’ll still be a few years centuries before our hard drives are fetching data 100,000x faster and our batteries last longer than our desire to use them.

Planet’s smallest model train set revealed to macro lenses, microscopes (video)

New Jersey’s own David Smith is enjoying his 15 minutes right about now, as the world is finally talking about his model train set. You see, this model train set isn’t just any model train set. No — it’s probably the world’s smallest, most ridiculous and most awesome all at once (all at once). The so-called James River Branch community has been in the works for months on end, and the $11 working locomotive is 35,200 times smaller than a real one. Of course, the moving trains are really just attached to the top of a rotating tube, but you can certainly pretend you never heard that spoiler if you’d like. Check the video after the break — the kid in you will thank us.

Nanotech Gloves: Use Your iPhone With or Without Your Hand

It’s getting cold outside, and soon your nimble fingers will be covered in warm, snuggly gloves that keep your digits warm but make it virtually impossible to navigate your iPhone. In fact, any capacitive touch-screen is pretty much beyond your reach (resistive works fine, thank you very much).

So you take off a glove and live with the cold, so you can touch your iPhone and virtually any one of the other 400 million capacitive touch screen devices you encounter–ATMs, gas stations, checkout counters, and the like.

On the other hand, you could simply use TouchTec’s new nano-technology-impregnated gloves and never remove them for a touch screen again (unless you want to). Check out my “hands-in” report in the video; more details after the jump.

Bring On the Replicator Already

A gadget site Taste Test week wouldn’t be complete without a hat tip to that fictional food-creating staple of the Star Trek universe, the replicator.

A replicator was a device that used transporter technology to dematerialize quantities of matter and then rematerialize that matter in another form. It was also capable of inverting its function, thus disposing of leftovers and dishes and storing the bulk material again. [Memory Alpha]

Yes, I know it’s not real. We got that bit out of the way right up there in the lead. Now we can have some fun hypothesizing and waxing all futuristic like about how these fantastical infinite buffets could (stress could) be possible some day.

In fact, in the most primitive sense, there’s a form of replication happening in manufacturing shops around the world right now. Called 3D printing, the technique isn’t even that new, with roots extending back to the 1990s. They were really expensive then, of course, but today they’re relatively ubiquitous in companies large and small. The technique is pretty simple. In layman’s terms, a user creates or downloads a 3D model of real world object on their workstation, and then a special printer works to recreate that object using resin or plaster or plastic or whatever the material may be. Voila. Instant prototype, and you can have all the tchotchke trinkets your heart desires, on demand, beamed to you from anywhere in the world.

But you can’t eat a resin hamburger. And you can’t drive the mockup that just got spit out of your rapid prototyping rig. The replicator could do both these things.

What we need is something that physically assembles atoms and molecules into tasty shapes so we can tell some uber supercomputer with a soothing female voice to get us some Tea. Earl Grey. Hot. Oh, and it has to create a little glass cup for us to drink it in too (Quick trivia: What did Picard do with all those dirty dishes? Answer above!).

This is where things get a bit sticky (food!), exciting (recent discoveries!) and depressing (its a LONG way off!) all at once. Theoretically, people are debating and thinking about “molecular assemblers” right this instant. In fact, these hypothetical machines would implement some form of nanotechnology, which is already used in everyday items like batteries, fuel technologies and even bikinis. Hell, there’s a Wikipedia page for molecular assemblers up right this instant—our replicator must be right around the corner, right?

Unfortunately, current nanotech implementations are almost what I’d call “dumb” deployments of the technology. We’re just coating a material with some nano bits to repel liquid; or we’re placing nanorods in a battery to improve efficiency… nothing, in other words, that would have Geordi doing a double take. Certainly not that Wesley Crusher kid either, for that matter (More asides: Wes, my man. Your replicators could produce anything you wanted—what the hell was up with that rainbow jumper?!).

But there is some hope. As recently as November, scientists had silver nanoparticles self-assembling into specific structures. Now, Guinan can’t serve us up a plate of silver, so that doesn’t really count as a replicator just yet, but it does drive our research in the right direction. The same direction that saw IBM scientists imaging molecular bonds for the first time ever on Thursday:

By “seeing” these bonds scientists think they can better understand how to manipulate them. For IBM scientists that means quantum processors and such in the far future. For guys and gals like you and me, it might mean snacks on demand as we start to understand why snacks look and feel the way they do on the molecular level.

While we’re down at the molecular level, I’d be remiss not to mention the nano pinhole camera some enterprising Russian scientists created in June:

In their atom pinhole camera, the atoms act like photons in an optical pinhole camera, but instead of light traveling through a lens, it travels through a pinhole on a mask and creates a high-res inverted image on a silicon substrate. This camera is capable of resizing nanostructures down to 30 nm-10,000 times smaller than the original. So, a camera with say 10 million pinholes could produce large numbers of identical (or diverse) nanostructures simultaneously.

It’s the most promising “replicator related” discovery in recent memory, but even so we joked that the Giz crew would probably be slurping pureed baby food and soiling our adult undergarments by the time it came to fruition. Then there’s the matter of energy and resource consumption, both of which add an exponential level of complexity onto any replicator roadmap. That IBM discovery above, just as a quick example to wrap things up, took a solid 20 hours of unmoving observation with a specialized microscope just to get that one black and white image.

Still, the research is there, and every month IBM or the CERN folks or someone else who’s much smarter than I am is firing off a new research paper about manipulating the world of the very, very small.

The replicator, in short, would be a paradigm shift the likes of which the world has never seen. It’d be worth the effort; the expense. Famine? Potentially gone forever. Shortages? See ya. Alinea? First place to get one. You and I? Optimistically speaking, we’ll probably need some Depends by the time one comes along. Silver lining is we can crap to our hearts content and dispose of the mess in our replicator. Then it’s lunch time!

Taste Test is our weeklong tribute to the leaps that occur when technology meets cuisine, spanning everything from the historic breakthroughs that made food tastier and safer to the Earl-Grey-friendly replicators we impatiently await in the future.
