'Problem wells' source of greenhouse gas

16-04-2014

High levels of the greenhouse gas methane were found above shale gas wells at a production point not thought to be an important emissions source, according to a study jointly led by Purdue and Cornell universities. The findings could have implications for the evaluation of the environmental ...

Glasses strong as steel

15-04-2014

Scientists at Yale University have devised a dramatically faster way of identifying and characterizing complex alloys known as bulk metallic glasses (BMGs), a versatile type of pliable glass that's stronger than steel. Using traditional methods, it usually takes a full day to identify a single ...

Sunlight generates hydrogen in new porous silicon

14-04-2014

Porous silicon manufactured in a bottom up procedure using solar energy can be used to generate hydrogen from water, according to a team of Penn State mechanical engineers, who also see applications for batteries, biosensors and optical electronics as outlets for this new material. The surface ...

Recycling astronaut urine for energy and drinking water

10-04-2014

On the less glamorous side of space exploration, there's the more practical problem of waste — in particular, what to do with astronaut pee. But rather than ejecting it into space, scientists are developing a new technique that can turn this waste burden into a boon by converting it into fuel and ...

Is the power grid too big?

Right-sizing the grid could reduce blackout risk, according to new analysis in the journal 'Chaos'

10-04-2014

Some 90 years ago, British polymath J.B.S. Haldane proposed that for every animal there is an optimal size -- one which allows it to make best use of its environment and the physical laws that govern its activities, whether hiding, hunting, hoofing or hibernating. Today, three researchers are ...

Trees go high-tech

Process turns cellulose into energy storage devices

09-04-2014

Based on a fundamental chemical discovery by scientists at Oregon State University, it appears that trees may soon play a major role in making high-tech energy storage devices. OSU chemists have found that cellulose – the most abundant organic polymer on Earth and a key component of trees – can ...

Rebar technique strengthens case for graphene

Rice University lab makes hybrid nanotube-graphene material that promises to simplify manufacturing

09-04-2014

Carbon nanotubes are reinforcing bars that make two-dimensional graphene much easier to handle in a new hybrid material grown by researchers at Rice University. The Rice lab of chemist James Tour set nanotubes into graphene in a way that not only mimics how steel rebar is used in concrete but ...

Organic solar cells more efficient with molecules face-to-face

09-04-2014

New research from North Carolina State University and UNC-Chapel Hill reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor molecules align face-on, rather than edge-on, relative to the acceptor. This finding may aid in the ...
