Apr. 23, 2013 ? There's big news in the world of tiny things. New research led by University of Cincinnati physics professors Howard Jackson and Leigh Smith could contribute to better ways of harnessing solar energy, more effective air quality sensors or even stronger security measures against biological weapons such as anthrax. And it all starts with something that's 1,000 times thinner than the typical human hair -- a semiconductor nanowire.
UC's Jackson, Smith, recently graduated PhD student Melodie Fickenscher and physics doctoral student Teng Shi, as well as several colleagues from across the US and around the world recently have published the research paper "Optical, Structural and Numerical Investigations of GaAs/AlGaAs Core-Multishell Nanowire Quantum Well Tubes" in Nano Letters, a journal on nanoscience and nanotechnology published by the American Chemical Society. In the paper, the team reports that they've discovered a new structure in a semiconductor nanowire with unique properties.
"This kind of structure in the gallium arsenide/aluminum gallium arsenide system had not been achieved before," Jackson says. "It's new in terms of where you find the electrons and holes, and spatially it's a new structure."
EYES ON SIZE AND CORNERING ELECTRONS
These little structures could have a big effect on a variety of technologies. Semiconductors are at the center of modern electronics. Computers, TVs and cellphones have them. They're made from the crystalline form of elements that have scientifically beneficial electrical conductivity properties. Many semiconductors are made of silicon, but in this case they are made of gallium arsenide. And while widespread use of these thin nanowires in new devices might still be around the corner, the key to making that outcome a reality in the coming years is what's in the corner.
By using a thin shell called a quantum well tube and growing it -- to about 4 nanometers thick -- around the nanowire core, the researchers found electrons within the nanowire were distributed in an unusual way in relation to the facets of the hexagonal tube. A close look at the corners of the tube's facets revealed something unexpected -- a high concentration of ground state electrons and holes.
"Having the faceting really matters. It changes the ballgame," Jackson says. "Adjusting the quantum well tube width allows you to control the energy -- which would have been expected -- but in addition we have found that there's a highly localized ground state at the corners which then can give rise to true quantum nanowires."
The nanowires the team uses for its research are grown at the Australian National University in Canberra, Australia -- one partner in this project that extends to disparate parts of the globe.
AFFECTING THE SCIENCE OF SMALL IN A BIG WAY
The team's discovery opens a new door to further study of the fundamental physics of semiconductor nanowires. As for leading to advances in technology such as photovoltaic cells, Jackson says it's too soon to tell because quantum nanowires are just now being explored. But in a world where hundreds of dollars' worth of technology is packed into a 5-by-2.5 inch iPhone, it's not hard to see how small but powerful science comes at a premium.
The team at UC is one of only about a half dozen in the US conducting competitive research in the field. It's a relatively young discipline, too, Jackson says, and one that's moving fast. For such innovative science, he says it's important to have a collaborative effort. The team includes scientists from research centers in the Midwest, the West Coast and all the way Down Under: UC, Miami University of Ohio and Sandia National Laboratories in California here in the US; and Monash University and the Australian National University in Australia.
The team's efforts are another example of how UC not only stands out as a leader in top-notch science, but also in shaping the future of the discipline by providing its students with high-quality educational and research opportunities.
"We're training students in state-of-the-art techniques on state-of-the-art materials doing state-of-the-art physics," Jackson says. "Upon completing their education here, they're positioned to go out and make contributions of their own."
Additional contributors to the paper are Jan Yarrison-Rice of Miami University, Oxford, Ohio; Bryan Wong of Sandia National Laboratories, Livermore, Calif.; Changlin Zheng, Peter Miller and Joanne Etheridge of Monash University, Victoria, Australia; and Qiang Gao, Shriniwas Deshpande, Hark Hoe Tan and Chennupati Jagadish of the Australian National University, Canberra, Australia.

Stephen Colbert hosts a South Carolina primary rally with former Republican presidential candidate Herman Cain at the College of Charleston, S.C., on Jan. 20, 2012.Photo by Jason Reed/Reuters
As the faux-conservative Colbert Report host, Stephen Colbert has lampooned campaign finance laws and the U.S. electoral system by starting his own super PAC and announcing bids for the presidency and ?the president of the United States of South Carolina.? But another Colbert?this one with a hard t at the end?is also vying for the political spotlight: Elizabeth Colbert Busch, Stephen?s older sister, who?s facing off against avid Appalachian Trail hiker and former South Carolina Gov. Mark Sanford in a May 7 special election for South Carolina?s 1st Congressional District. Colbert has twice devoted show segments to his sister?s campaign, including one endorsing her candidacy, and has mocked Sanford on countless occasions. With the show?s nightly viewership of 1.5 million and the documented ?Colbert bump? in a politician?s support after an appearance, is Colbert violating election laws by blending his hosting role with his sister?s campaign?
Probably not. The central law in play is the Federal Communications Commission?s equal-time rule. Beginning with the Radio Act of 1927, which Congress enacted in response to fears of broadcasters? ability to sway elections by limiting a candidate?s access to the airwaves, radio and television networks have been required to offer equal airtime (or opportunities to purchase advertising at a reduced price) to all candidates if they request it. Exemptions were later added for documentaries, newscasts, news interviews, and on-the-spot news events.
Since it covers news stories and political issues, The Colbert Report would likely fall under the newscast or news interviews exceptions. This exemption would permit Colbert to interview his sister on his show without giving Sanford equal time. However, Sanford would have seven days after Colbert Busch?s first appearance to file an equal-time request; if turned down, Sanford could file a complaint to the FCC.
Mentions or endorsements of Colbert Busch?s campaign or jokes at Sanford?s expense would not be considered in-kind campaign gifts. Though the Federal Election Commission has previously tried to argue these mentions could count as campaign contributions, free-speech issues and FCC rulings have trumped any attempts by the FEC to regulate this speech. Viacom, the parent company of The Colbert Report, may exercise more caution in this case?or at least do extra vetting with its lawyers. Since corporations are barred from making campaign contributions to federal candidates, Colbert could potentially raise legal issues for Viacom if he?s coordinating his message with his sister?s campaign, though again Colbert?s endorsements or mentions likely are covered by the newscast exception to the equal-time rule.
Outside his show, Colbert has hosted several fundraisers for his sister, including two $500-to-$10,000-per-ticket events in Washington, D.C., and New York. These donations would be filed to the FEC with names and amounts listed and would go toward Colbert Busch?s campaign. This contrasts with the campaign finance laws Colbert mocked through his now-defunct Americans for a Better Tomorrow, Tomorrow super PAC, which allowed him to collect unlimited donations from his fans before he shut down the super PAC in December and split the remaining funds among several charities. If Colbert decided to revive his super PAC for his sister?s campaign, he should not also fundraise directly for his sister?s campaign, since super PACs are barred from coordinating with candidates.
Colbert Busch is currently favored by likely voters 50 percent to Sanford?s 41 percent, according to Public Policy Polling. Her campaign may be getting a boost from the Colbert bump (and from Sanford?s stumbles), but Colbert is in the clear to keep preaching his brand of truthiness for his sister?s campaign. And the rest of us are eager for a sibling showdown on The Colbert Report?s ?Better Know a District.?

HAMBURG, Pa. (AP) ? Five days into spring, warm weather and budding flowers were just a rumor Monday as the East Coast endured another blast of winter.
A wide-ranging storm that buried parts of the Midwest weakened as it moved east but still managed to carpet lawns and fields in a fresh layer of white. Many schools opened late or closed early, and hundreds of flights were canceled.
The cold temperatures and miserable mixture of snow and rain had people longing for more agreeable weather.
"I'm ready for flip flops," said Jessica Cunitz, 24 of Westchester County, N.Y., who stopped at a gas station along Interstate 78 in Pennsylvania to fill her overheating car with antifreeze. "It's supposed to be spring."
In Maryland, Michael Pugh donned a wool coat, knit cap, waterproof pants and heavy boots to trudge more than a mile through four inches of wet snow to his bank in downtown Hagerstown, about 70 miles west of Baltimore. He pronounced the weather "dreadful."
By this time of year, "I was hoping it'd be sunny and the weather breaking," said Pugh, a warehouse worker who turned 38 Monday. "Every day I think I can pack up the winter coat, and break out the spring clothes, and I can't."
Earlier, the storm walloped the Midwest, dumping a record 17 inches in Springfield, Ill., and a foot or more elsewhere in the state. Travel remained treacherous Monday afternoon, with Interstate 55 and 57 still covered in snow and ice, according to the Illinois Department of Transportation. Numerous vehicles were reported to be off roads, according to Illinois state police.
In downtown Springfield, coffee-shop manager Mike Zengilani said food-delivery trucks were hours late. But he didn't think about closing.
"Everyone else closes, so it's good for us to be open," Zengilani said. "It's Monday, it's definitely slower, but we all made the effort to come in."
The system was little more than a nuisance by the time it reached the East Coast. Air travel saw the biggest impact, with nearly 600 flights canceled as of Monday afternoon, according to the FlightAware tracking service. Hardest-hit airports included those in New York, Philadelphia and Washington.
Roadways, meanwhile, were mostly wet.
In Hamburg, Pa. ? which has seen three here-and-gone snowfalls in little more than a week ? carpet installer Seth Hanna drank coffee and surveyed the slush from a covered front porch.
"We got these warm days a few weeks ago, and everybody got their hopes up. March is supposed to be out like a lamb but it's not doing it," said Hanna, 30. "I love the snow, but I'm ready for some warm spring weather."
Robert Fink, 25, of Magnolia, N.J. said the worst part about yet another snow storm was having to shovel. Fink ? shovel in hand outside a truck stop in Bordentown ? said he longed for Florida, where he used to live.
"I'm a wimp when it comes to the cold," he said.
At the U.S. Supreme Court in Washington, people waiting in line for tickets to this week's arguments on gay marriage held umbrellas or put tarps over their belongings as the snow fell. Darienn Powers wore a trash bag from the waist down to keep dry, but said the snow still made everything "a little wet and uncomfortable."
The spring snow was not expected to affect Washington's famous cherry blossoms. National Park Service spokeswoman Carol Johnson said the flowering trees are still expected to reach peak bloom between April 3 and April 6.
Mitchell Gaines, a meteorologist with the National Weather Service in Mount Holly, N.J., said colder-than-normal temperatures the past few weeks had created conditions ripe for snow.
"It's fairly late in March to see a system like this," he said.

Along with a complete restructuring to remove contracts with its 'Simple Choice' plans, T-Mobile is also consolidating its prepaid plans to fall into line. Previously a distinctly separate business for T-Mobile under the "Monthly 4G" branding, the magenta carrier's prepaid plans are now available at each of the same tiers as the Simple Choice plans. $50, $60 or $70 monthly will get you unlimited talk and text along with 500MB, 2.5GB or unlimited unthrottled data, respectively. Previously, the $60 plan offered 2GB of data and the $50 plan an awkwardly low 100MB of data.
One thing that hasn't changed in its prepaid offerings are the lower level of plans, of which there are still several options. T-Mobile still offers the somewhat-famous $30 prepaid plan with 100 minutes and 5GB of full-speed data, as well as the other $30 plan at 1500 minutes and 30MB of data. There are still "pay as you go" plans with rates between $10 and $100 for minute-only plans, as well as "pay by the day" plans at $3/day for unlimited talk, text and web or $2/day for the same restricted to 2G speeds.
It's actually unclear at this point what distinction -- if any -- will be made between its primary and prepaid plans going forward, and we wouldn't at all be surprised to see stand-alone prepaid plans go away for all but the lowest tiers. There's little to no reason for the current duplication of $50, $60 and $70 plans, and they're likely to slowly fade away as the two sets of plans integrate.

Fan of channels such as CMT, VH1 Classic and Teen Nick? Cablevision is assuming that's a negatory. Today, the cable provider filed a federal antitrust suit against Viacom over the content distributor's programming bundling practices, which are alleged as anti-competitive. The lawsuit revolves around Viacom's insistence that ancillary networks be included in programming agreements in order to gain distribution rights to more popular networks such as Nickelodeon, MTV and Comedy Central. While the complaint itself remains under seal, Cablevision is arguing abuse of power in the lawsuit, which if successful, could have rippling effects throughout the pay-TV industry.
Cablevision is seeking declaratory relief that would void the two companies' programming contract (inked just this past December), along with a permanent injunction against Viacom's practice and the ability to carry Viacom programming until a new contract can be negotiated. Meanwhile, Viacom has asserted that it'll vigorously defend the lawsuit, and maintains that its practice is "win-win and pro-consumer" in the sense that its niche networks are offered at discounts. It seems that we can look forward to both companies butting heads for a while to come.
