UD graduate creates headpieces and hats used in hit movie ‘The Hunger Games’
Gina Scarnati and her assistants were blaring Queen from their iPod and enjoying a rare, brief moment of down time when Woody Harrelson walked in to their massive room of hats. (more…)
Electrochemical capacitors (ECs), also known as supercapacitors or ultracapacitors, differ from regular capacitors that you would find in your TV or computer in that they store substantially higher amounts of charges. They have garnered attention as energy storage devices as they charge and discharge faster than batteries, yet they are still limited by low energy densities, only a fraction of the energy density of batteries. An EC that combines the power performance of capacitors with the high energy density of batteries would represent a significant advance in energy storage technology. This requires new electrodes that not only maintain high conductivity but also provide higher and more accessible surface area than conventional ECs that use activated carbon electrodes.
Now researchers at UCLA have used a standard LightScribe DVD optical drive to produce such electrodes. The electrodes are composed of an expanded network of graphene — a one-atom-thick layer of graphitic carbon — that shows excellent mechanical and electrical properties as well as exceptionally high surface area.

AUSTIN, Texas — A new study examining nearly 40 years of satellite imagery has revealed that the floating ice shelves of a critical portion of West Antarctica are steadily losing their grip on adjacent bay walls, potentially amplifying an already accelerating loss of ice to the sea.
The most extensive record yet of the evolution of the floating ice shelves in the eastern Amundsen Sea Embayment in West Antarctica shows that their margins, where they grip onto rocky bay walls or slower ice masses, are fracturing and retreating inland. As that grip continues to loosen, these already-thinning ice shelves will be even less able to hold back grounded ice upstream, according to glaciologists at The University of Texas at Austin’s Institute for Geophysics (UTIG).

A new assessment of wind energy in India by Lawrence Berkeley National Laboratory has found that the potential for on-shore wind energy deployment is far higher than the official estimates— about 20 times and up to 30 times greater than the current government estimate of 102 gigawatts. This landmark finding may have significant impact on India’s renewable energy strategy as it attempts to cope with a massive and chronic shortage of electricity.
“The main importance of this study, why it’s groundbreaking, is that wind is one of the most cost-effective and mature renewable energy sources commercially available in India, with an installed capacity of 15 GW and rising rapidly,” says Berkeley Lab scientist Amol Phadke, the lead author of the report. “The cost of wind power is now comparable to that from imported coal and natural gas-based plants, and wind can play a significant role in cost effectively addressing energy security and environmental concerns.” (more…)
Researchers have devised a nanoscale sensor to electronically read the sequence of a single DNA molecule, a technique that is fast and inexpensive and could make DNA sequencing widely available.
The technique could lead to affordable personalized medicine, potentially revealing predispositions for afflictions such as cancer, diabetes or addiction. (more…)
UD anthropology course examines ‘Muslim Delaware’
When Patricia Sloane-White speaks of Muslim Delaware, she’s often met with a look of disbelief from students, from members of the community, from colleagues who all ask the same question: Well, where is it? (more…)
Chemistry team discovers new catalyst
A chemistry team at the University of Toronto has discovered environmentally-friendly iron-based nanoparticle catalysts that work as well as the expensive, toxic, metal-based catalysts that are currently in wide use by the drug, fragrance and food industry. (more…)
*Study Conducted with EXPO Shows Persuasive Elements of User-Generated Product Videos Lift Brand Affinity When Used in Tandem with Professionally-Produced Content*
NEW YORK, NY and RESTON, VA, March 28, 2012 – comScore, Inc., a leader in measuring the digital world, and EXPO, the 
first consumer network focused on creating and distributing high impact product videos to drive engagement and conversion, today released the results of a study on the synergy of professionally-produced video content and user-generated product videos in marketing campaigns. The study evaluated an actual campaign that included a combination of a professionally-produced “how to” video and a user-generated product video that was created and submitted by an actual product user. The results of the study indicate that professionally-produced video content and user-generated product videos are highly synergistic, driving higher levels of sales effectiveness when used in tandem.
