Copper-nickel nanowires from Duke University could make ubiquitous printable circuits
Nanowires, although they're building steam, still have to overcome the not-so-small problem of cost -- they often have to use indium tin oxide that's not just expensive, but fragile. Duke University has developed copper-nanowire films that could remedy this in style. The choice of material is both a hundred times less expensive to make than indium and is much more durable. It's flexible, too: if layered on as a coating, the nanowires would make for considerably more viable wearable electronics that won't snap under heavy stress. The catch, as you might suspect, stems from the copper itself, which doesn't conduct as much electricity as indium. The nickel will keep your copper electronics from oxidizing faster than the Statue of Liberty, however. Any practical use could be years away, but further successes from Duke could quickly see printable electronics hit the mainstream power and power our dreams of flexible displays.
Fuel cells get stronger, potentially cheaper with graphene, ITO
As the sustainable Juggernaut of fuel cell vehicles (FCV) powers ever forward, a group of scientists are cooking up ways to make the alternative energy source more durable and even cheaper. By combining graphene -- think pencil lead -- and indium tin oxide (ITO) nanoparticles, the team produced a catalytic material that is both stronger and more chemically active than the usual catalytic combo. Fuel cells typically use a chemical catalyst like platinum, sitting atop a base of black carbon or metal oxides, to break down oxygen and hydrogen gases, creating water in the process -- thing is, carbon is easily eroded by the resulting water, and metal oxides, while more stable, are less conductive. Using graphene -- which because of its porousness erodes less quickly -- in combination with the stable ITO and platinum nanoparticles, researchers have created what could be referred to as a super fuel cell -- a stronger, longer lasting, and potentially cheaper version of the alternative energy source. Unfortunately, without enough hydrogen filling stations, these super fuel cells won't come to anyone's rescue anytime soon.
Samsung's MEMS shutter could massively improve high megapixel cameraphones
We won't go so far as to say that SE and LG are waiting for this here technology to go commercial -- after all, we're still years (at best) away from that -- but considering that the ninth iteration of your favorite smartphone is likely destined to boast a 453 megapixel camera, we're thrilled to see someone working to make those captures worth looking at. Over in Japan, Sammy is teasing a new MEMS shutter that measures just 2.2 millimeters in diameter and would essentially allow cameraphones to grab blur-free images even with ultra-high megapixel sensors. Feel free to dive into the read link if you're into technobabble; otherwise, just be sure to pay attention in around a decade when this stuff actually has a bearing on your life.
