Two graphene layers may be better than one

April 28, 2011 5:02 am | News | Comments

Researchers at NIST have shown that the electronic properties of two layers of graphene vary on the nanometer scale. The surprising new results reveal that not only does the difference in the strength of the electric charges between the two layers vary across the layers, but they also actually reverse in sign to create randomly distributed puddles of alternating positive and negative charges. The new measurements bring graphene a step closer to being used in practical electronic devices.


Study: China's energy consumption will stabilize

April 28, 2011 4:42 am | News | Comments

Well before 2050, according to a new study by Berkeley Lab's China Energy Group, China's energy use will level off, even as its population edges past 1.4 billion. There will come a time—within the next two decades—when the number of people in China acquiring cars, larger homes, and other accouterments of industrialized societies will peak. Between 2030 and 2035, the steeply rising curve of energy demand in China will begin to moderate and flatten thereafter.


New technique could lead to superconducting transistors for power-saving electronics

April 28, 2011 4:25 am | News | Comments

Like atomic-level bricklayers, researchers from Brookhaven National Laboratory are using a precise atom-by-atom layering technique to fabricate an ultrathin transistor-like field effect device to study the conditions that turn insulating materials into high-temperature superconductors.


Artificial nose can diagnose bacterial infections

April 28, 2011 4:04 am | News | Comments

Bacterial infections really stink. And that could be the key to a fast diagnosis. Researchers have demonstrated a quick, simple method to identify infectious bacteria by smell using a low-cost array of printed pigments as a chemical sensor.


Flow through heaters

April 28, 2011 3:41 am | Product Releases | Comments

Omega Engineering’s FTH series of flow through heaters are designed primarily for providing heat that regulates liquid temperature from 32 to 88°C (90 to 190°F).

Polystat laboratory baths and circulators

April 28, 2011 3:37 am | Product Releases | Comments

Cole-Parmer Polystat circulating baths and immersion circulators offer temperature stability for a range of laboratory applications.

New submersible capable of return to deepest ocean depths

April 27, 2011 7:03 am | News | Comments

Triton Submarines this week announced the impending release of their Triton 36,000 full ocean depth submersible. Featuring passenger cockpit approximately six feet in diameter and made entirely of borosilicate glass developed using a new process from Rayotek Scientific, the sub will offer the possibility of a return to the deepest part of the ocean in more than 50 years.


Shrinking funds pull plug on alien search devices

April 27, 2011 6:48 am | by Marcus Wohlsen, Associated Press | News | Comments

A steep drop in both state and federal funds has forced the shutdown of the Allen Telescope Array in California. The $50 million array was built by SETI and UC Berkeley with the help of Microsoft Corp. co-founder Paul Allen, but it costs more than a million dollars a year to operate. SETI will continue its work at other telescopes.


How plants deal with stress

April 27, 2011 6:03 am | News | Comments

Like people, plants experience stress. And also, like people, the response to that stress can determine success. People can exercise, or rest, or talk about the problem. For plants, ways to deal with stress are internal. And ISU researchers are trying to understand how they do it.


Caterpillars inspire new movements in soft robots

April 27, 2011 5:52 am | News | Comments

Researchers have been examining the diverse behaviours of caterpillars to find solutions for the new generation of search and rescue soft robots.


Report: Storage for spent nuclear fuel more crucial than ever

April 27, 2011 5:26 am | by David L. Chandler, MIT News Office | News | Comments

The United States and other countries around the world looking to nuclear power for their energy needs must consider how spent fuel will be handled as they construct new plants and examine existing ones, especially in light of the recent crisis in Japan, according to a comprehensive study from MIT.


NIST prototypes framework for evaluating sustainability standards

April 27, 2011 5:05 am | News | Comments

As manufacturers and other businesses step up efforts to cut waste, reduce energy use, and improve the overall sustainability of their products and processes, the number of planet-friendly standards and regulations also is increasing at a rapid clip, creating a sometimes-confusing array of options for "going green." NIST researchers have prototyped a framework to help organizations of all types sort through the welter of choices and evaluate and implement sustainability standards most appropriate for their operations and interests.


NIST nanomagnets offer food for thought about computer memories

April 27, 2011 4:53 am | News | Comments

Magnetics researchers at the National Institute of Standards and Technology (NIST) colored lots of eggs recently. Bunnies and children might find the eggs a bit small—in fact, too small to see without a microscope. But these "eggcentric" nanomagnets have another practical use, suggesting strategies for making future low-power computer memories.


'Nanobead' approach could revolutionize sensor technology

April 27, 2011 4:26 am | News | Comments

Researchers at Oregon State Univ. have found a way to use magnetic "nanobeads" to help detect chemical and biological agents, with possible applications in everything from bioterrorism to medical diagnostics, environmental monitoring, or even water and food safety.
