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.
Printable body armor, better bulletproof glass, and tougher steel are just a few of the applications for a new materials technology developed by Israeli researchers. A team of scientists there have developed a transparent material made of self-assembling nanospheres that is the stiffest organic material ever created, surpassing the properties of stainless steel and even Kevlar.
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.
Water, water everywhere, but in the developing world or in areas ravaged by natural disasters – like the ongoing flooding in Pakistan, for instance – there's often not a clean, purified drop to be found.
You can't throw a rock in the realm of biotech right now without hitting some scheme or another for tapping the unique properties of nanoparticles to hunt tumors, target drug delivery, or monitor the body internally for specific biomarkers. But a perhaps unlikely field of scientific exploration is also tapping these nano-biotechnology applications to search for the elusive hydrocarbons that are its lifeblood: the oil industry.
Nano-thin sheets of metal can be used to build a tiny high-definition display, according to University of Michigan researchers. They built a 9-micron-high image of their logo to prove it.
The pixels in the display are an order of magnitude smaller than those on a typical computer screen. They are roughly eight times smaller than the pixels on the iPhone 4.
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.
A new nano-scale wiretap device could tell researchers about the inner workings of cells, according to a new Harvard study.
It involves a transistor that can take electrical readings, embedded inside a membrane that fits inconspicuously inside an individual living cell. The tiny probe, which is smaller than many viruses, is the first semiconductor device to take measurements of the inside of a cell.
Micro electromechanical systems–or MEMS–hold a lot of promise for the future of high tech, but they also have their drawbacks, namely that they aren’t very precise. That’s because at such small scales there are no standards by which to measure very small forces or distances. But a team of Purdue researchers has developed a way for MEMS to self-calibrate, potentially opening the door to a variety of super-precise sensors and instruments used in everything from medicine to engineering to defense.
Putting the right kind of strain on a patch of graphene can make super-strong pseudo-magnetic fields, a new study says. The finding sheds new light on the properties of electromagnetism, not to mention the odd properties of graphene, according to researchers at Lawrence Berkeley National Laboratory. When graphene is stretched to form "nanobubbles," the stress causes electrons to behave as if they were subject to huge magnetic fields, the size of which have never been seen in a lab before. The study is published today in the journal Science.
Michael Crommie, a senior scientist in the Materials Sciences Division at Berkeley Lab and a physics professor at the University of California-Berkeley, says this is a completely new effect that has no counterpart in any other condensed matter system.
