Like a lot of things, bone cells grow and reproduce quicker on textured surfaces than on smooth ones. With that in mind, a team of scientists from Ohio State University are developing a new coating that could allow implants such as artificial hips to bond with bones faster. That coating is described as “a microscopic shag carpet made of tiny metal oxide wires.” Read More
Transparent electrodes are in and of themselves nothing all that new – they’re currently used in things like touchscreens and flat-screen TVs. Thanks to research being conducted at Indiana’s Purdue University, however, a new class of such electrodes may soon find use in a variety of other applications, including flexible electronic devices.

In some peoples’ opinion, electric cars won’t become truly viable until their batteries offer a lot more driving range, and can be recharged much more quickly than is currently possible. Well, those people may soon be getting their wish. Scientists at the University of Southern California have developed a new type of lithium-ion battery, that they claim holds three times as much energy as a conventional li-ion, and can be recharged in just ten minutes.

In a breakthrough that could lead to more efficient and cheaper solar cells, scientists at Sweden's Lund University claim to have identified the ideal diameter for nanowires to convert sunlight into electricity. Read More
Under its human skin, James Cameron’s Terminator was a fully-armored cyborg built out of a strong, easy-to-spot hyperalloy combat chassis – but judging from recent developments, it looks like Philip K. Dick and his hard-to-recognize replicants actually got it right. In a collaboration between Harvard, MIT and Boston Children's Hospital, researchers have figured out how to grow three-dimensional samples of artificial tissue that are very intimately embedded within nanometer-scale electronics, to such an extent that it is hard to tell where one ends and the other begins. It could lead to a breakthrough approach to studying biological tissues on the nanoscale, and may one day be used as an efficient, real-time drug delivery system – and perhaps, why not, even to build next-generation androids.

Earlier this year, a team led by North Carolina State University’s Dr. Yong Zhu reported success in creating elastic conductors made from carbon nanotubes. Such conductors could be used in stretchable electronics, which could in turn find use in things like bendable displays, smart fabrics, or even touch-sensitive robot skin. Now, he has made some more elastic conductors, but this time using silver nanowires – according to Zhu, they offer some big advantages over carbon nanotubes. Read More
Higher-density batteries, more efficient thin-film solar cells, and better catalysts may all soon be possible, thanks to a new technique that allows nanowires to be “decorated” with nanoparticles. Using the novel technology, scientists from Stanford University have been able to festoon the outside surfaces of nanowires with intricate chains of metal oxide or noble metal nanoparticles, thereby drastically boosting the effective surface area of the nanowires. Other researchers have previously tried to achieve the same end result, but apparently never with such success. Read More
Physicists at the Delft University of Technology, Netherlands, have achieved a milestone that might soon revolutionize the world of quantum computing, quantum physics, and perhaps shed new light on the mystery of the dark matter in our universe. Experimenting with nanoelectronics, a group led by Prof. Leo Kouwenhoven has succeeded in detecting the elusive Majorana fermion in the laboratory, without the need for a particle accelerator.

French researchers have produced highly conducive plastic fibers with a thickness of only a few nanometers that self-assemble when exposed to a flash of light. The tiny fibers (one nanometer equals one billionth of a meter) could become a cheaper and easier-to-handle alternative to carbon nanotubes and play a role in the development of electronic components on the nanoscale.

While hydrogen is considered a “clean” fuel because the only waste product it generates is water, the conventional way to produce it relies on electricity, which is usually produced through the burning of fossil fuels. Researchers at the University of California, San Diego (UCSD), have now developed a “3D branched nanowire array” that they claim could cheaply and cleanly deliver hydrogen fuel on a mass scale.
