Photovoltaics generated $38 billion in 2009

Worldwide solar photovoltaic (PV) installations reached a record high of 6.43 gigawatt (GW) in 2009-a 6% Y/Y growth, according to the latest Marketbuzz 2010 Report from Solarbuzz, an international solar energy market research and consulting company, and a division of The NPD Group.

Wastewater sludge to be turned into 600 kW a day

Wastewater sludge to be turned into 600 kW a day

The project hasn’t reached full-scale yet, but the renewable energy research project that started out in a Nevada lab has reached demonstration stage at a water reclamation facility. The process dries sludge that is normally trucked away for disposal, converting it to solid fuel that can be gasified to produce electricity.

Nano-based RFID tags could replace bar codes

Nano-based RFID tags could replace bar codes

A carbon-nanotube-infused ink for ink-jet printers first developed in the Rice Univ. lab of James Tour has been used to make thin-film transistors in radio-frequency identification tags that can be printed on paper or plastic. The transmitter can be invisibly embedded in packaging, instantly sharing far more information than a bar code.

Unexpected finding: Light can twist ribbons of nanoparticles

Unexpected finding: Light can twist ribbons of nanoparticles

In findings that took the experimenters three years to believe, Univ. of Michigan engineers and their collaborators have demonstrated that light itself can twist ribbons of nanoparticles.

DNA nanotubes offer promising applications in medicine

A team of McGill Chemistry Department researchers led by Dr. Hanadi Sleiman has achieved a breakthrough in the development of nanotubes—tiny "magic bullets" that could one day deliver drugs to specific diseased cells.

Solving hydrogen storage issues with layered graphene sheets

Solving hydrogen storage issues with layered graphene sheets

Graphene—carbon formed into sheets a single atom thick—now appears to be a promising base material for capturing hydrogen, according to recent research at the National Institute of Standards and Technology (NIST) and the Univ. of Pennsylvania. The findings suggest stacks of graphene layers could potentially store hydrogen safely for use in fuel cells and other applications.

Turning proteins into glass

Duke Univ. researchers have devised a method to dry and preserve proteins in a glassified form that seems to retain the molecules' properties as workhorses of biology.

Testimony: Mastery of rare earth elements vital to U.S. security

Testimony: Mastery of rare earth elements vital to U.S. security

Karl A. Gschneidner Jr., a senior metallurgist at Ames Lab, spoke before a House Subcommittee this week, cautioning them that rare-earth R&D in America is “virtually zero”. He went on to say that expertise in rare-earth alloying is crucial to economic performance and that the U.S. has given up much ground to other countries in this area.

Laser makes silicon pump liquid uphill with no added energy

Researchers at the Univ. of Rochester's Institute of Optics have discovered a way to make liquid flow vertically upward along a silicon surface, overcoming the pull of gravity, without pumps or other mechanical devices.

Metallic glass yields secrets under pressure

Metallic glass yields secrets under pressure

Metallic glasses are emerging as potentially useful materials at the frontier of materials science research. They combine the advantages and avoid many of the problems of normal metals and glasses, two classes of materials with a very wide range of applications.

Lunar tires, space MRSA, and resonating microfluidics

Lunar tires, space MRSA, and resonating microfluidics

I typically attend the annual Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy each year in pursuit of specific coverage. This year, I sought out candidates for coverage in a vacuum technology article, and pulled together some instruments for a spectroscopy guide. But as busy as that kept me, it wasn’t all mass spectrometers and vacuum pumps on the show floor.  

A clean energy America…is it coming or not?

A clean energy America…is it coming or not?

Almost a year ago, the buzz during the downturn was that the economic stimulus will help boost jobs in a sort of national improvement program reminiscent of the 1930s. Our coal would be phased out. Our grids would get smart. Our cars would get hybridized.

Daytime running light has just two LEDs

The new OSTAR Compact LED from OSRAM has been developed specifically for use in vehicle headlights. Despite drawing just 5 W, the device provides 300 lumens of power and meets ECE/SAE color binning requirements for use on motor vehicles.

DuPont Performance Polymers launches new nylon for automotive industry

A new family of nylon products from DuPont Performance Polymers—DuPont Zytel PLUS nylon—delivers high performance levels and maintains those high performance levels despite exposure to hot oil, hot air, calcium chloride, and other aggressive automotive chemicals.

LithStor building provides solutions for lithium batteries

Safety Storage LithStor prefabricated storage buildings meet specialized containment needs for businesses and industry, military, homeland security, and government agencies managing the storage of new and used lithium batteries.

Airflow in subways could spread contaminants

As part of a Homeland Security study on the spread of airborne contaminants released in subway systems, Berkeley Lab researchers are measuring the flow of gas throughout tunnels and cars. Subways created significant airflow as they move through tunnels, which could raise risk in the event of a terrorist attack or spill.
