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

Everything is Bigger in Texas, but These New Gas Turbines Up the Ante
GE – Harriet, whose real name is the 9HA, is the largest and most efficient gas turbine in the world.
GE spent more than $1 billion to develop the turbines. The company built a special testing center in Greenville, where engineers are currently putting the first Harriet through tests.
The turbine, which was manufactured at a GE plant in Belfort, France, is equipped with more than 3,000 sensors. They collect mechanical, temperature and exhaust data, and feed it to a brand new data-crunching center next door.
Under the hood, Harriet combines designs and materials originally developed by GE scientists for supersonic jet engines and other advanced technology. They include aerodynamic blades made from single-crystal alloys, thermal barrier coatings and ceramic matrix composites. Later generations of the turbine will also include 3D-printed parts. more> http://tinyurl.com/m2np8km

The Century-Old Panama Canal is Opening Up to a Busy Future
GE – The Panama Canal is a full century old, but that doesn’t mean it still can’t grow. The 48-mile-long landmark that cuts across “the backbone of the Western Hemisphere” is going through the final year of a massive expansion. When work is completed in 2015, new locks will allow giant “New Panamax” class of container ships and supertankers through and boost the canal’s capacity by half.
In 1914, the canal used 500 GE motors to operate the locks, with 500 more installed elsewhere in the system. GE also built the power plants that provided the canal with electricity and designed the centralized control equipment for the locks.
One historian noted that GE “produced about half the electrical equipment needed during construction and virtually all of the permanent motors, relays, switches, wiring and generating equipment. They also built the original locks towing locomotives and all of the lighting.”
Those 40 electric towing locomotives were made in Schenectady, NY. Since ships were not permitted to pass through the locks under their own power, these “lock mules” rode on rails next to the canal and pulled them through the locks. Custom gears and electrical design allowed them to run as slow as 1 mph, the speed required for gently tugging large vessels. more> http://tinyurl.com/kuvm694

This Deconstructed Locomotive Will Power Nigeria’s Economy
GE – Nigeria has fast become Africa’s largest economy, but its infrastructure is still lagging.
The electrical grid is so unpredictable that many businesses use natural gas to produce their own power. That’s why GE engineers recently converted a powerful diesel engine from a locomotive into an efficient stationary power plant that can produce enough electricity to supply a factory, or 6,600 Nigerian homes.
The project was also an exercise in FastWorks, a set of tools and principles currently transforming GE culture into a leaner and faster company working close to customers. more> http://tinyurl.com/l9zvfj9

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
