The role of goop: Research shows pollution doesn't change the rate of droplet formation
20-02-2013
When it comes to forming the droplets that make up clouds, a little oily and viscous organic material apparently doesn't matter that much. And that's good news for reducing the uncertainty of climate model predictions. Understanding cloud formation is essential for accurate climate modeling, ...
Pyroelectric nanogenerator charges Li-ion battery with harvested energy
26-11-2012
The idea of harvesting ambient energy from the environment that would otherwise not be purposefully used is, in theory, a great way to produce green, renewable energy. But the biggest problem in this fairly new area of research is that scientists have yet to find a method that can harvest ...
Low-resistance connections facilitate multi-walled carbon nanotubes for interconnects
02-11-2012
Using a new method for precisely controlling the deposition of carbon, researchers have demonstrated a technique for connecting multi-walled carbon nanotubes to the metallic pads of integrated circuits without the high interface resistance produced by traditional fabrication techniques.Based ...
Study shows availability of hydrogen controls chemical structure of graphene oxide
Metastable material
24-05-2012
A new study shows that the availability of hydrogen plays a significant role in determining the chemical and structural makeup of graphene oxide, a material that has potential uses in nano-electronics, nano-electromechanical systems, sensing, composites, optics, catalysis and energy ...
New graphene fabrication method uses silicon carbide templates to create desired growth
Smoothing the edges
14-10-2010
Researchers at the Georgia Institute of Technology have developed a new "templated growth" technique for fabricating nanometer-scale graphene devices. The method addresses what had been a significant obstacle to the use of this promising material in future generations of high-performance ...
ARPA-E funding supports research on carbon dioxide removal from flue gases
24-08-2010
Researchers at the Georgia Institute of Technology are using funding from the Advanced Research Projects Agency - Energy – also known as ARPA-E – to pursue two different, but related, approaches for removing carbon dioxide from the flue gases of coal-burning power plants. Power plants ...
LSU researcher receives NSF rapid response grant to study health of marshes impacted by oil
Brings together three universities to develop detailed analysis and insight into molecular-level affects
12-08-2010
LSU Associate Professor of Chemistry Robert Cook has recently received a rapid response grant from the National Science Foundation, or NSF, to investigate the impact of oil from the Deepwater Horizon disaster on Louisiana's highly fertile, productive and delicate marshlands by studying ...
Push-Button Logic on the Nanoscale
09-08-2010
Circuits that can perform logic operations at the push of a button are a dime-a-dozen these days, but a breakthrough by researchers in the USA has meant they can be smaller and simpler than ever before. Using a single material as both the button and the circuit for the first time, scientists ...
Scientists strive to replace silicon with graphene on nanocircuitry
15-06-2010
Scientists have made a breakthrough toward creating nanocircuitry on graphene, widely regarded as the most promising candidate to replace silicon as the building block of transistors. They have devised a simple and quick one-step process based on thermochemical nanolithography (TCNL) for ...
Seeing moire in graphene
03-05-2010
Researchers at the National Institute of Standards and Technology (NIST) and the Georgia Institute of Technology have demonstrated that atomic scale moiré patterns, an interference pattern that appears when two or more grids are overlaid slightly askew, can be used to measure how sheets of ...
