While this "nanoflower" looks like a carnation, it is actually the result of a new technique in creating many-layered nanostructures that greatly amp up the amount of surface area one can work with in a small space and could lead to more efficient and safer batteries and solar cells.
The science of holography has taken a big leap forward thanks to tiny carbon nanotubes. Scientists at Cambridge University have used carbon nanotubes to generate the smallest hologram pixels ever created. The small size is key, because the smaller the pixel, the higher the resolution of the hologram and the wider the field of view.
Until now, stitches and surgical sutures have acted matter-of-factly as medical tools — they close your wound until the incision or cut heals. Now, there's a new kind of suture on the horizon, one that comes fitted with micro-thin sensors to monitor the health of the wound, as well as deliver healing heat to the site on the fly.
Researchers have devised a method for printing full-color images at an unprecedented resolution. This ultra-high-definition printing method uses tiny rods (measured in the tens of nanometers) to manipulate light at the smallest scales, resulting in the highest resolution images allowed...
If you didn't get a chance to open your latest issue of the American Chemical Society's journal Nano Letters, it details new research into microscopic "factories" running on "DNA and other biological machinery." These can be implanted in the body, where they will assemble and release drugs locally into specific disease sites.
A team at MIT has identified how the formation of droplets of water when condensation occurs could significantly increase the efficiency of all kinds of power and desalination plants. According to the team, the secret is in the size of the droplets.
From yarn to batteries to space elevators, it seems like there's nothing that carbon nanotubes can't do. And for their latest trick, they can make things completely disappear.
Piezoelectric generators take motion and turn it into electricity. They've been used to convert muscle movement into energy to run medical implants, but it's been hard to get them to scale up enough to power stuff that's bigger and more fun. Researchers at Georgia Tech have been able to create a tiny piezoelectric nanogenerator that's capable of powering an LED and a liquid crystal display, and your iPod is going to be next.
Imagine a building that had windows that opened and closed without your help — and without motors — to keep a room at its optimal temperature. Or paper with ink that carried an electric charge. Both concepts sound crazy, but they're made possible with "NanoINK," a substance currently in development.
Ever have someone bitterly play the world's smallest violin at you? Well, two fingers rubbing together isn't going to cut it anymore: Johan Engelen and his fellow students really have created the world's smallest violin and it even produces music...
