Researchers Create ‘Nanoflowers’ for Energy Storage, Solar Cells

Researchers from North Carolina State University have created flower-like structures out of germanium sulfide (GeS) – a semiconductor material – that have extremely thin petals with an enormous surface area. The GeS flower holds promise for next-generation energy storage devices and solar cells.

“Creating these GeS nanoflowers is exciting because it gives us a huge surface area in a small amount of space,” says Dr. Linyou Cao, an assistant professor of materials science and engineering at NC State and co-author of a paper on the research. “This could significantly increase the capacity of lithium-ion batteries, for instance, since the thinner structure with larger surface area can hold more lithium ions. By the same token, this GeS flower structure could lead to increased capacity for supercapacitors, which are also used for energy storage.” (more…)

Commentary: Sergei Khrushchev – The Cuban Missile Crisis, 50 years later

October marks the 50th anniversary of of the 13-day Cuban Missile Crisis, when President John F. Kennedy discovered that the Soviet Union was building secret missile bases in Cuba. Forgoing the option of a Cuban invasion or air strikes, Kennedy asked Russian Premier Nikita S. Khrushchev to remove all weapons from the island, and on Oct. 28, 1962, Khrushchev conceded, halting the standoff. Here, Khrushchev’s son, Sergei Khrushchev, visiting professor of Slavic languages at Brown, reflects on the diplomatic lessons.

The perspective of the crisis has changed over time and today the history of the crisis is more focused not on the confrontation, but on cooperation.

The Cuban Missile Crisis showed that two leaders decided not to shoot first, but to think and negotiate with each other. And today that is very unusual, because we think we can only negotiate with friends. Today, we impose unconditional surrender and nobody surrenders unconditionally until fully defeated. (more…)

Beyond Bieber: Twitter Improves Student Learning

EAST LANSING, Mich. — Twitter, best known as the 140-character social-networking site where Justin Bieber and Lady Gaga chit-chat with fans, has become a new literary format that is improving student learning, a new study argues.

Christine Greenhow, assistant professor of education at Michigan State University, found that college students who tweet as part of their instruction are more engaged with the course content and with the teacher and other students, and have higher grades.

“Tweeting can be thought of as a new literary practice,” said Greenhow, who also studies the growing use of social media among high-schoolers. “It’s changing the way we experience what we read and what we write.” (more…)

Shark Social Networking

Shark migrations studied with underwater robot along Delmarva Peninsula

University of Delaware researchers are using an underwater robot to find and follow sand tiger sharks that they previously tagged with transmitters. The innovative project is part of a multi-year partnership with Delaware State University to better understand the behavior and migration patterns of the sharks in real time.

“In the past week our new, specially equipped glider OTIS – which stands for Oceanographic Telemetry Identification Sensor – detected multiple sand tiger sharks off the coast of Maryland that were tagged over the past several years,” said Matthew Oliver, assistant professor of oceanography in UD’s College of Earth, Ocean, and Environment. “This is the first time that a glider has found tagged sharks and reported their location in real time.” (more…)

Tablets Reinvent Americans’ Relationship with Print

Nearly 2 in 5 Tablet Owners Read Newspapers and Magazines on Their Device in August

Kindle Fire Owners Most Likely to Consume News According to comScore TabLens

RESTON, VA, October 17, 2012 – comScore, Inc., a leader in measuring the digital world, today released a study of tablet newspaper and magazine readership based on data from its comScore TabLens service. The study found that nearly 2 in 5 U.S. tablet owners read newspapers and/or magazines on their device in August, with 1 in 10 reading publications almost daily. Analysis of readership activities across platforms revealed that Kindle Fire users displayed the strongest propensity for reading newspapers and magazines on their device.

“Tablets are fundamentally redefining how people consume news and information, with the format more conducive to reading longer form content than PCs or smartphones,” said Mark Donovan, comScore SVP of Mobile. “In the case of online newspapers, tablets are now driving 7 percent of total page views, an impressive figure considering the relative infancy of the tablet space. Publishers that understand how these devices are shifting consumption dynamics will be best positioned to leverage this platform to not only drive incremental engagement among current subscribers but also attract new readers.” (more…)
