Nanocrystals and nickel catalyst substantially improve light-based hydrogen production

November 15, 2012

rochester_nanocrystals

Hydrogen is an attractive fuel source because it can easily be converted into electric energy and gives off no greenhouse emissions. A group of chemists at the University of Rochester is now adding to its appeal by increasing the output of current light-driven hydrogen-production systems while lowering the cost.

The chemists say their work advances what is sometimes considered the “holy grail” of… read more

Can cloud computing boost GDP?

November 15, 2012

Cloud_Computing

Gross domestic product (GDP) can be boosted by cloud computing, the system in which remote computers on the Internet are used to store, manage and process data rather than the users’ local machines, according to a report to be published in the International Journal of Technology, Policy and Management. 

The report suggests that governments should collaborate to boost the adoption… read more

New metamaterial lens focuses radio waves

Device could improve satellite and molecular imaging
November 15, 2012

The orientation of 4,000 S-shaped units forms a metamaterial lens that focuses radio waves with extreme precision, and very little energy lost (credit: Dylan Erb/MIT)

MIT researchers have fabricated a three-dimensional, lightweight metamaterial lens that focuses radio waves with extreme precision.

The concave lens exhibits a property called negative refraction, bending electromagnetic waves — in this case, radio waves — in exactly the opposite sense from which a normal concave lens would work.

Concave lenses typically radiate radio waves… read more

Hovering moon base may be on NASA’s horizon

November 16, 2012

orion-earth-moon-telerobotics-astronauts

NASA is considering plans for a hovering moon base parked in orbit about 60,000 kilometers from the moon’s far side, at Lagrange point 2 (EML-2), New Scientist reports.

There, the combined gravity of Earth and the moon would tug on a spacecraft with exactly the force needed for it to hover near the moon without spending fuel. This might assist human missions to an asteroid or to Mars… read more

Lost in space: rogue planet spotted?

November 16, 2012

rogue_planet_eso

Astronomers have identified an object that could be a planet wandering through space without a parent star at a distance of about 100 light-years. Its closeness and the absence of a nearby bright star have allowed the team to study its atmosphere in great detail.

Free-floating planets are planetary-mass objects that roam through space without any ties to a star. Possible… read more

Carbon nanotubes may protect DNA from oxidation

November 16, 2012

Scanning electron microscope image of a typical sample of the NIST single-wall carbon nanotube soot standard reference material. Recent NIST research suggests that, at least in the laboratory, carbon nanotubes may help protect DNA molecules from damage by oxidation. The image shows an area just over a micrometer wide.

Single-wall carbon nanotubes (SWCNTs) may help protect DNA molecules from damage by oxidation, researchers at the National Institute of Standards and Technology (NIST) have found.

In nature, oxidation is a common chemical process in which a reactive chemical removes electrons from DNA and may increase the chance for mutations in cells.

More studies are needed to see if the in vitro protective effect of… read more

‘Cloning’ could make structurally pure nanotubes for nanoelectronics

May be key to separating electrical conductors and semiconductors
November 16, 2012

Cloning nanotubes: In this computer model, small, pre-selected nanotube "seeds" (yellow) are grown to long nanotubes of the same twist or "chirality" in a high-temperature gas of small carbon compounds (Credit: Jia Liu et al./USC)

A technique for growing virtually pure samples of single-wall carbon nanotubes (SWCNTs) with identical structures has been demonstrated by researchers from the University of Southern California (USC) and the National Institute of Standards and Technology (NIST).

They liken this process to “cloning” the nanotubes. If it can be suitably scaled up, their approach could solve an important materials problem in nanoelectronics: producing carbon nanotubes… read more

Nanotech yarn behaves like super-strong muscle

Could one day power robots, micromotors, intelligent textiles
November 16, 2012

ut_nanotube_muscles

New artificial muscles made from nanotech yarns and infused with paraffin wax can lift more than 100,000 times their own weight and generate 85 times more mechanical power than the same size natural muscle, according to scientists at The University of Texas at Dallas and their international team from Australia, China, South Korea, Canada and Brazil.

New injectable gels toughen up after entering the body

November 16, 2012

mit_injectable_gel

MIT chemical engineers have designed an injectable gel that responds to the body’s high temperature by forming a reinforcing network that makes the gel much more durable, allowing it to function over a longer period of time.

Gels that can be injected into the body, carrying drugs or cells that regenerate damaged tissue, hold promise for treating… read more
