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.
Ito Electronics shows off waterproof OLED displays
Details are about as light as can be on this one, but it looks like Japan's Ito Electronics has developed some sort of special "packaging technology" that can make OLED displays fully waterproof, which could be particularly used for watches, cellphones, or that fish tank home theater you've always dreamed of. Of course, there's no word on any actual products just yet, nor is there any indication of possible transparent waterproof displays -- or, at least, none that anyone has seen.[Via OLED-Info.com]
Resin replaces ITO in latest flexible OLED prototype
Make no mistake, wrapping your mind around the build of an OLED panel is mighty tough to do. Without getting you mired in technobabble, let's just say that indium tin oxide (ITO) has generally been a mainstay in every single OLED that was produced commercially. Now, a team of researchers from AGFA-Gevaert, IMEC, Holst Centre and Philips have prototyped a 12- x 12-centimeter flexible OLED lighting panel that swaps out the ITO for highly-conductive transparent resin electrodes. You see, it's been difficult for OLED builders to secure enough electrical conductivity of ITO in a low-temperature process, and this new methodology is perfectly suited for the coating method (which makes it ripe for printing). The resin itself is being dubbed Orgacon, and tests have shown it to have a 6x improvement over ITO in terms of electrical conductivity. Beyond that, the crews are keeping the secrets safe from the poachers of the world, but here's hoping this amounts to more than just jovial celebration in a far off laboratory.[Via OLED-Display]
