Highly flexible organic semiconductors: Research paves way for thin-sheet plastic displays or wearable electronics

Feb. 15, 2013 ? Organic semiconductors hold promise for making low-cost flexible electronics -- conceivably video displays that bend like book pages or roll and unroll like posters, or wearable circuitry sewn into uniforms or athletic wear. Researchers have demonstrated the ability to "print" transistors made of organic crystals on flexible plastic sheets, using technology that resembles inkjet or gravure printing.

However, for the technology's potential to be realized, scientists have to show that these organic semiconductors will withstand the rugged handling they invite -- they will need to perform reliably in spite of frequent flexing and sharp bending.

In an article published Dec. 11, 2012 in Nature Communications, scientists led by Rutgers University physicist Vitaly Podzorov report they have demonstrated extremely flexible organic semiconductors that withstood multiple bending cycles in which the devices were rolled to a radius as small as 200 micrometers. The scientists worked with numerous crystalline devices they made and found no degradation in their performance.

Podzorov claims his is the first rigorous study of solution-crystallized organic semiconductors under various types of strain -- sharp bending and repeated flexing along with compression and stretching. He acknowledges some earlier encouraging studies of mechanical robustness, but felt those lacked rigorous tests of flexibility involving different types of organic semiconductors, especially those that show the most promise for development of low-cost printed electronics. The scientists at Rutgers focused on two soluble small molecules (developed in the group of Prof. John Anthony at the University of Kentucky), depositing and crystallizing them on thin plastic sheets from solution, and claim the results should apply to numerous other organic formulations that researchers are investigating.

Turtle Beach?s New Seven Series Headphones Are A Gamer?s Audio Dream

Screen Shot 2013-02-18 at 11.44.08 AMIf you're a hard-core gamer, the name Turtle Beach most certainly means something to you. We met with the tournament-grade headset maker to discuss their new Seven series of headsets, originally debuted at CES. There are three different models in the line, the XP Seven (meant for all consoles, PC, and mobile), the Z Seven (meant for PC and mobile) and the M Seven (mobile only). Both the XP Seven and the Z Seven come with a special Audio Control Unit (or ACU) that lets you adjust even the most minute details of the audio.

Rome Courtyard by Marriott project awaits design revisions

by Doug Walker, Associate Editor Rn T.Com

The Marriott Corp. wants some changes to the design of the proposed Courtyard by Marriott on West Third Street in Rome before giving final approval to the project.

Rome City Manager John Bennett said that he had gotten a notice from Marriott officials Monday afternoon.

?What they are doing in Rome is a custom facility,? Ben-nett said.

The fact that the Rome hotel is being built on top of a parking deck means that the local project deviates significantly from the Courtyard by Marriott prototype.

?As of last Thursday they had to go back to the drawing board and make a few changes, plus changes relative to the swimming pool,? Bennett said. The restaurant and lobby sections of the hotel also differ from the typical Courtyard by Marriott design.

?We are very supportive of the project and in a collaborative effort we are working with Duke Hospitality in making a few design revisions that will improve the project, including the requirement for a swimming pool,? the letter from Marriott officials reads. ?I am confident that we will have their project finalized within a couple of weeks.?

The City Manager said the letter came out of the Marriott regional office in Orlando.

Duke Hospitality officials are in the process of building a new Fairfield Inn & Suites by Marriott in Duluth.

(AP) ? A leading Republican senator said Sunday he would hold up Senate confirmation of President Barack Obama's nominees to head the Defense Department and the CIA until the White House provided more answers about the deadly Sept. 11 attack against a U.S. installation in Benghazi, Libya.

The White House took aim at Sen. Lindsey Graham, a persistent critic of Obama's response to the terrorist assault, by urging quick approval of the president's second-term national security team and scolding any lawmakers trying to "play politics" with critical nominations.

Graham accused the White House of "stonewalling" requests to release more information about the attack that killed four Americans, including the U.S. ambassador to Libya. "We're going to get to the bottom of Benghazi," he told CBS.

A Democratic colleague branded Graham's threat to stall the nominations of former Sen. Chuck Hagel to be defense secretary and John Brennan, Obama's top counterterrorism adviser, to be CIA director as "unprecedented and unwarranted." Senators should have the chance to vote on the fate of those nominees, said Sen. Jack Reed.

The White House did not address Graham's demand for more information, but did note that Defense Secretary Leon Panetta and Army Gen. Martin Dempsey, the chairman of the Joint Chiefs of Staff, testified Thursday before Congress about the chaotic day of the Sept. 11 attack.

Republicans have accused the Obama administration of an election-year cover-up of the attack, and at the hearing several suggested the commander in chief was disengaged as Americans died.

"We know nothing about what the president did on the night of September 11th during a time of national crisis, and the American people need to know what their commander in chief did, if anything, during this eight-hour attack," Graham said on CBS.

Graham contended that a six-person rescue team was delayed from leaving the Benghazi airport because of problems "with the militias releasing them and a lot of bureaucratic snafus," and he said he wants to know whether Obama called any Libyan officials to expedite their mission.

"I don't think we should allow Brennan to go forward for the CIA directorship, Hagel to be confirmed to secretary of defense until the White House gives us an accounting," Graham said, adding, "What did he do that night? That's not unfair. The families need to know, the American people need to know."

Tommy Vietor, a spokesman for the White House's National Security Council, said, "We believe the Senate should act swiftly to confirm John Brennan and Sen. Hagel. These are critical national security positions and individual members shouldn't play politics with their nominations."

Reed said that "to dwell on a tragic incident and use that to block people is not appropriate. To try to find information, to ask legitimate questions, as Senator Graham is doing is completely appropriate. But then to turn around and say, 'I'm going to disrupt, essentially, the nomination of two key members of the President's Cabinet,' I don't think that's appropriate, I don't think it's warranted, I think it is an overreaction that is not going to serve the best interest going forward of the national security of the United States."

Graham would have none of it.

"In a constitutional democracy, we need to know what our commander in chief was doing at a time of great crisis, and this White House has been stonewalling the Congress, and I'm going to do everything I can to get to the bottom of this so we'll learn from our mistakes and hold this president accountable for what I think is tremendous disengagement at a time of national security crisis," he said.

At the Senate hearing, Panetta testified that he and Dempsey were meeting with Obama when they first learned of the Libya assault. He said the president told them to deploy forces as quickly as possible. Graham asked whether Panetta spoke again to Obama after that first meeting. Panetta said no, but that the White House was in touch with military officials and aware of what was happening. At one point, Graham asked Panetta if he knew what time Obama went to sleep that night. The Pentagon chief said he did not.
