A humble spice found in nearly every kitchen could yield a safer, simpler way to produce gold nanoparticles, according to a new study. Researchers say the cinnamon-infused particles can even be used to fight cancer.
Peeing on your phone seems like an all-around pretty bad idea, but British researchers have managed to find an upside. They claim that by urinating on a computer chip and plugging it into a phone or computer, people will soon be able to easily self-diagnose sexually transmitted diseases.
A new fuel-free propulsion system for nanodevices works like a disappearing act, dissolving an object at one end and re-generating it at the other end.
The method requires an electrical current to work, so it’s not completely energy-free, but it could be an effective way to propel nanoscale materials inside nano- or micro-devices. It could even lead to disappearing magical motors that vanish once their task is complete.
New DARPA-funded research could revolutionize portable power supplies, leading to lithium-ion batteries that are smaller than a grain of salt.
Jane Chang, an engineer at the University of California-Los Angeles, is designing a tiny solid electrolyte that allows charge to flow between two nanoscale electrodes. Eventually, the wee batteries could be used to power a host of micro and nanodevices.
Space technology is about to make your visit to the dentist a little more comfortable. The same production technology that made the world’s tiniest rocket motor will be used to shrink those unwieldy plastic squares the dentist sticks in your mouth during an X-ray.
Israeli researchers have created the tiniest-ever optical gyroscopes, as small as a grain of sand, but still maintaining the keen accuracy of their counterparts hundreds of times larger. Optical gyroscopes are generally used for navigation in airplanes, ships and satellites, in which they track movement without reference to external navigation points, by measuring the vehicle's rotation rate and linear acceleration. This is called inertial navigation.
Human skin is primed for touch — even minuscule pressure from a fly is enough to make you flinch. This ability does not yet extend to artificial limbs, however, and robots are a long way from having sensitive tactile abilities.
Now two California research teams have announced pressure-sensitive artificial skin made of tiny circuits, both of which could lead to better artificial limbs and helper robots.
A dash of this, a pinch of that, and it seems researchers at Northwestern have cooked up a new class of nanostructures that aren't just ideal for such applications as gas storage or medical technologies, but also edible. The team, which began their research with a completely different outcome in mind, found that their recipe produced natural and edible metal-organic frameworks (MOFs), porous crystalline structures with unique properties that are usually difficult to make and composed of toxic petroleum products.
Almost exactly one year ago, two Chinese women earned the distinction of becoming the first humans to be killed by nanotechnology, after nanoparticles in a paint used in their poorly ventilated factory took residence in their lungs, causing respiratory failure. Now a team of researchers at North Carolina State have developed a method of modeling the way nanoparticles interact with biological systems, giving medical and nanotech researchers their first means to predict how a given particle will move through a human body.
