With a pair of 9-0 wins over Denison and Georgetown at the Navy Squash Veterans Weekend Round Robin on Sunday, the Midshipmen pushed their unbeaten streak to 13 after the first two weeks of the season. Navy began the weekend with a 7-0 record, adding a pair of wins in each of the last three days.
(Nanowerk News) Cell phones as thin and flexible as a sheet of paper. Energy-storing house paint. Roll-up touch screen displays. These are the sorts of devices that the engineering industry is preparing for and expecting. But if any of them is to work, said Northeastern University mechanical and industrial engineering professor Yung Joon Jung, experts also need to create a thin and flexible energy-storage system. His lab has developed such a system.
Using their novel carbon nanocup material, Yung Joon Jung and Hyunyoung Jung have developed a supercapacitor that is both flexible and transparent.
In a recently published article in the journal Scientific Reports ("Transparent, flexible supercapacitors from nano-engineered carbon films"; open access), Jung and colleagues from Northeastern and Rice University presented their design of a flexible and transparent supercapacitor, a device that stores energy as an electrical field instead of a chemical reaction, as batteries do. As such, it is a prime energy-storage candidate for the thin, flexible devices of the future.
The technology is based on a nanomaterial developed in Jung?s lab two years ago, which they call a nanocup. One of the perceived advantages of nanotubes, Jung explained, is the potential to fill them with other materials, such as electrolyte in the case of a supercapacitor. The inner capacity of nanotubes has turned out to be too small to achieve this capability, ?but if you have a cup,? Jung said, pointing to his own coffee mug, ?you can put anything in it you want.?
The first step to making a nanocup is etching nanoscopic divots into an aluminum film through oxidation. By tweaking the voltage and time of this process, researchers can tailor the size of the cups. The second step is to layer carbon atoms onto the aluminum mold using standard carbon nanotube technology.
Hyunyoung Jung, the first author on the paper and a postdoctoral researcher in Professor Jung?s lab, has a background in polymer chemistry. He emphasized that the new supercapacitor?s novelty derives from the large surface area and the open textured surface of the nanocups. This morphology allows them to come into greater contact with the electrolyte, which drives the formation of an electrical field and thus the energy storage functionality.
The supercapacitor, which has not yet been optimized, is able to store energy and provide power at levels comparable to other devices. The difference, however, is its ability to be incorporated into thin film devices. ?If we give up transparency and mechanical flexibility,? Jung said, ?we can easily go to that level of commercially available devices. But my goal is not to lose these two qualities and simultaneously develop high-performance energy devices.?
The research team has already used a flexible and transparent prototype to power a light. The group plans to make continued improvements in power generation and energy storage.

World stock markets struggled Friday despite encouraging Chinese economic figures as fears persisted over the so-called U.S. "fiscal cliff" that's seen as a big threat to the economic recovery.
In early European trading, the FTSE 100 index of leading British companies was down 0.3 percent at 5,757.69 while Germany's DAX was 0.7 percent lower at 7,152.63. The CAC-40 in France slipped 0.1 percent to 3,404.89.
U.S. stocks were also poised to edge down on the open. Dow futures were down 0.1 percent to 12,759 while the broader S&P 500 futures were down the same rate at 1,373.80. Asian markets closed lower.
Markets have slumped worldwide as investors have refocused on challenges to the world economy following President Barack Obama's re-election. Many worry that gridlock in Washington will prevent the president and Congress from reaching a deal before $800 billion of tax increases and government spending cuts kicks in on Jan. 1.
Investors also have renewed fears about Europe's lingering debt crisis. European Central Bank President Mario Draghi warned that the economy of the 17 nation grouping that uses the euro remains weak and will struggle to grow even with "visibly improved" confidence among the currency union's financial markets.
Those fears offset somewhat upbeat indicators in China that provided signs of a possible recovery in the world's second-largest economy. The latest data showed that Chinese factory output rose, investment growth strengthened and inflation eased in October.
Looking ahead, investors will focus on consumer sentiment survey out of the U.S. Analysts say the University of Michigan consumer sentiment index will likely dip because of the impact of Superstorm Sandy, but remain at relatively strong levels.
Japan's Nikkei 225 index fell 0.9 percent to close at 8,757.60 and Hong Kong's Hang Seng shed 0.9 percent to end at 21,384.38. South Korea's Kospi retreated 0.5 percent to 1,904.41.
The Shanghai Composite Index closed down 0.1 percent to 2,069.07 and the Shenzhen Composite Index edged 0.4 percent lower to 828.46.
Australia's S&P ASX 200 dropped 0.5 percent to 4,462.00 after the central bank released a downbeat assessment of the country's economy.
Australian stocks fell after the country's central bank said in a quarterly report it was trimming growth forecasts as mining companies scale back investment plans because of declining iron ore and coal prices and the strong currency.
In currencies, the euro weakened to $1.2723 from to $1.2750 late Thursday. The dollar was roughly unchanged against the Japanese yen at 79.22 yen.
Crude oil for December delivery was down 48 cents to $84.61 in electronic trading on the New York Mercantile Exchange. The contract rose 65 cents to close at $85.09 on Thursday.
