Copper Film Could Lower Touch Screen, LED And Solar Cell Costs
2011-09-27 04:03:32

Copper nanowires may be coming to a little screen near you. These new nanostructures have the potential to drive down the costs of displaying information on cell phones, e-readers and iPads, and they could also help engineers build foldable electronics and improved solar cells, according to new research. Duke chemist Ben Wiley and his graduate student have developed a technique to organize copper atoms in water to form long, thin, non-clumped nanowires. The nanowires are then...

Accidental Sea Turtle Deaths Down, But Still Too High
2011-09-15 04:48:28

  Some 4,600 sea turtles are accidentally caught and killed in U.S. fisheries every year, a 94 percent reduction since 1990, according to a new study published this month in the journal Biological Conservation. However, the progress may not be enough to sustain turtle populations, according to researchers at Duke University's Project Global and Conservation International, who conducted the study. The use of turtle-excluder devices (TEDs), or large holes that allow the sea...

While roofs across the world sport photovoltaic solar panels to convert sunlight into electricity, a Duke University engineer believes a novel hybrid system can wring even more useful energy out of the sun's rays. Instead of systems based on standard solar panels, Duke engineer Nico Hotz proposes a hybrid option in which sunlight heats a combination of water and methanol in a maze of glass tubes on a rooftop. After two catalytic reactions, the system produces hydrogen much more efficiently...

Discovery may have implications for many diseases Cells are the building blocks of the human body. They are a focus of scientific study, because when things go wrong at the cellular and molecular level the consequences for human health are often significant. A new finding based on multiple collaborations between UNC and Duke scientists over several years points to new avenues for investigation of cell metabolism that may provide insights into diseases ranging from neurodegenerative disorders...

Electrical engineers at Duke University have developed a material that allows them to manipulate light in much the same way that electronics manipulate flowing electrons. The researchers say the results of their latest proof-of-concept experiments could lead to the replacement of electrical components with those based on optical technologies. Light-based devices would enable faster and more efficient transmission of information, much in the same way that replacing wires with optical fibers...

Researchers from UC Riverside and Duke University propose a new and less expensive approach to treating depression. Practicing positive activities may serve as an effective, low-cost treatment for people suffering from depression, according to researchers at the University of California, Riverside and Duke University Medical Center. In "Delivering Happiness: Translating Positive Psychology Intervention Research for Treating Major and Minor Depressive Disorders," a paper that appears in the...

By altering the genetic makeup of normally "unexcitable" cells, Duke University bioengineers have turned them into cells capable of generating and passing electrical current. This proof-of-concept advance could have broad implications in treating diseases of the nervous system or the heart, since these tissues rely on cells with the ability to communicate with adjacent cells in order to function properly. This communication is achieved through the passage of electrical impulses, known as...

Anoles show they can solve novel problem, remember solutions Tropical lizards may be slow. But they aren't dumb. They can do problem-solving tasks just as well as birds and mammals, a new study shows. A Duke University experiment tested Puerto Rican anoles on several cognitive tasks and found they can learn and remember to solve a problem they've never faced before. The results challenge the scientific stereotype that reptiles have limited cognitive abilities and methods for finding food. The...


Word of the Day
caparison
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
