R&D – OLEDs (organic light emitting diodes) are the latest and greatest in television technology, allowing screens to be extremely thin and even curved, with little blurring of moving objects and a wider range of viewing angles. In these “RGB” displays, each pixel contains red, green and blue modules that shine at different relative brightness to produce any color desired.
But not all OLEDs are created equal.
Phosphorescent OLEDs, also known as PHOLEDs, produce light through a mechanism that is four times more efficient than fluorescent OLEDs. Green and red PHOLEDs are already used in these new TVs—as well as in Samsung and LG smartphones—but the blues are fluorescent. more> http://tinyurl.com/ng4l8uk

By Dan D’Ambrosio – “It’s hard to buy a smartphone that doesn’t have IBM content in it today,” senior technical staff member Mark Jaffe said.
“I have a Samsung Galaxy S4. I think this has nine chips that we make in it.”
If somebody cracked open Jaffe’s smartphone, there would be no chips bearing the IBM logo. That’s by design.
IBM sells to suppliers who sell to manufacturers including Apple Inc. and Samsung Group. IBM has no plans to launch its equivalent of the “Intel Inside” campaign. more> http://tinyurl.com/mtm2mvq

Honey, I Shrunk the World: How Materials Scientists Made the Globe Smaller
GE – Composites are made from alternating layers of fiber and sheets of carbon, plastic or ceramics, kind of like industrial-grade baklava.
When joined together, composites can be tougher and lighter than steel or titanium. “This was a huge, expensive and risky project,” says Shridhar Nath, who leads the composites lab at GE Global Research. “We planned to replace titanium with what is essentially plastic. We were starting from scratch and we did not know how carbon fiber blades would respond to rain, hail, snow and sand, and the large forces inside the engine.”
The bet paid off and GE has, over time, invested billions more in materials science. The composites research delivered a new line of large, fuel efficient jet engines like the GE90 and GEnx, that changed the economics of aviation forever. “The engines essentially opened the globe up to incredibly efficient, twin-powered, wide-body planes,” says David Joyce, president and CEO of GE Aviation.
The latest engine in that family, the GE9X, will power Boeing’s next-generation 777X long-haul jets. Light-weight carbon composites allowed engineers to design an 11-foot fan that can suck a maelstrom of 8,000 pounds of air per second inside the engine. The air will flows into the combustor, where it meets parts made from ceramic matrix composites (CMCs), another breakthrough material developed by GE scientists.
Carbon fiber composites work with cold air at the front of the engine. But CMCs operate in the engine’s hot section, at temperatures where even metals grow soft. The extra heat gained by the ceramics gives the engine more energy to work with and makes it more efficient.
CMCs also have twice the strength and just a third of the weight of their metal counterparts. This allows designers to make parts from them thinner and much lighter, further reducing the weight of the engine. more> http://tinyurl.com/lt5wlnn

Das Instant Auto: Say Hallo to a Hot Rod Powered by Water
GE – The intriguingly named Quant e-Sportlimousine has been making a splash in Europe, where it was just approved for road use. The electric vehicle can go from 0 to 62 miles per hour in a ridiculous 2.8 seconds, reach a projected top speed of 217 mph, and has a range of 370 miles for one charge, according to its manufacturer, Liechtenstein-based NanoFlowCell AG. Oh, and it’s powered by a saltwater-filled battery.
Unlike traditional batteries, which use solid materials to store and release electricity, flow batteries use charged liquids kept in separate tanks. The charged liquids come into close proximity only during power generation, greatly reducing the possibility of fire. “The safety is much higher and the electrode materials degrade much less during service,” Dr. Grigorii Soloveichik says. “You can re-use them many, many times.”
Soloveichik says flow batteries could hold “tens of kilowatt-hours and up” of energy, since it is the size of the tanks that determines how much power the batteries can store. Besides cars, flow batteries could be used as backup power for commercial and residential systems, store electricity from renewable sources of energy, and also support the power grid. “They can store energy from wind, for example, so power companies can use it when they need it,” Soloveichik says. more> http://tinyurl.com/l5cuos2
