Rice University 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.

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.

Philips to unveil saliva-based roadside drug test later this year

In the vein of the breathalyzer, Philips has developed an on-the-go drug test, that can be used by the side of the road to test suspected imbibers for cocaine, heroin, cannabis, amphetamines and methaphetamine. Unlike the standard alcohol testing equipment, this one is used by having the suspect spit into a small receptacle, which is then inserted into the measurement chamber which contains magnetic nanoparticles coated with ligands that bind to one of five different drug groups, delivering color coded test results in about 90 seconds. Philips, which has been developing the device since 2001, built it as an optical device that would be easy to mass produce for law enforcement. The company expects to ship them by the end of the year, though there’s no word on exactly which markets will employ them as of yet.

Tiny, printable batteries promise to change the face of obnoxious greeting cards forever

Researchers at the Fraunhofer Research Institution for Electronic Nano Systems ENAS in Chemnitz led by Prof. Dr. Reinhard Baumann have unveiled tiny, printable batteries that they hope to put into production for pennies apiece. The new battery prototype is primarily composed of a zinc anode and a manganese cathode that can be screen printed and covered with a non-printed template cover. Each mercury-free battery weighs less than one gram, and can individually produce about 1.5 volts of electricity. By placing several batteries side by side, however, up to 6 volts can be generated. The institute has already produced these little power houses in the lab, and hopes to see them into production by the end of the year. The batteries have a relatively short lifespan, making them suitable for applications such as powering greeting cards. All we can say is that this battery would have made the card we got two years ago that sang “Word Up” much, much awesomer.
