NC State crafts nanoflowers that boost battery and solar cell capacity, would make great prom accessories

We see a lot of sleek-looking technology pass through our doors, but it's rare that the inventions could be called beautiful by those who aren't immersed in the gadget world. We'd venture that North Carolina State University might have crossed the divide by creating an energy storage technology that's both practical and genuinely pretty. Its technology vaporizes germanium sulfide and cools it into 20-30 nanometer layers that, as they're combined, turn into nanoflowers: elegant structures that might look like the carnation on a prom dress or tuxedo, but are really energy storage cells with much more capacity than traditional cells occupying the same area. The floral patterns could lead to longer-lived supercapacitors and lithium-ion batteries, and the germanium sulfide is both cheap and clean enough that it could lead to very efficient solar cells that are more environmentally responsible. As always, there's no definite timetable for when (and if) NC State's technology might be commercialized -- so call someone's bluff if they promise you a nanoflower bouquet.

Phase change memory breakthrough could lead to gigahertz-plus data transfers, make SSDs seem pokey

Numonyx phase change memory

Often considered the eventual successor to flash, phase change memory has had a tough time getting to the point where it would truly take over; when it takes longer to write data than conventional RAM, there's clearly a roadblock. The University of Cambridge has the potential cure through a constant-power trick that primes the needed hybrid of germanium, antimony and tellurium so that it crystalizes much faster, committing data to memory at an equally speedy rate. Sending a steady, weak electric field through the substance lets a write operation go through in just 500 picoseconds; that's 10 times faster than an earlier development without the antimony or continuous power. Researchers think it could lead to permanent storage that runs at refresh rates of a gigahertz or more. In other words, the kinds of responsiveness that would make solid-state drives break out in a sweat. Any practical use is still some distance off, although avid phase change memory producers like Micron are no doubt champing at the bit for any upgrade they can get.
