| How graphene's electrical properties can be tuned Posted: 26 Sep 2011 11:46 AM PDT Graphene is ideally suited for creating components for semiconductor circuits and computers. Now, an accidental discovery in a physicist's laboratory, provides a unique route for tuning the electrical properties of graphene. The researchers found that stacking up three layers of graphene, like pancakes, significantly modifies the material's electrical properties. This simple and convenient "tuning knob" holds great promise for replacing silicon with graphene in the microchip industry.  |
| Catalyst discovery potential has to revolutionize chemical industry Posted: 26 Sep 2011 10:20 AM PDT Researchers have discovered a remarkably active catalyst that has the potential to revolutionize the chemical industry.  |
| Researchers develop optimal algorithm for determining focus error in eyes and cameras Posted: 26 Sep 2011 10:18 AM PDT Researchers have discovered how to extract and use information in an individual image to determine how far objects are from the focus distance, a feat only accomplished by human and animal visual systems until now.  |
| Cheap and efficient solar cell made possible by linked nanoparticles Posted: 26 Sep 2011 10:14 AM PDT Researchers have demonstrated that electrons can move freely in layers of linked semiconductor nanoparticles under the influence of light. This new knowledge will be very useful for the development of cheap and efficient quantum dot solar cells.  |
| E-textiles get fashion upgrade with memory-storing fiber Posted: 26 Sep 2011 07:46 AM PDT In the future when you upgrade your computer, you may also be upgrading your wardrobe as researchers create novel new textiles that pull double-duty as fabrics and electronics.  |
| Sneaking up on the glassy transition of water Posted: 26 Sep 2011 07:46 AM PDT Researchers claim to have settled a long-standing debate over the exact temperature at which water transforms into an exotic glass-like substance believed to be present in comets and other icy objects in the outer solar system, as well as in the coldest regions of the Earth's atmosphere.  |
| Handling nanoscale particles: 'Next-generation' optical tweezers trap tightly without overheating Posted: 26 Sep 2011 07:41 AM PDT Engineers have created a device that may make it easier to isolate and study tiny particles such as viruses. Their plasmonic nanotweezers use light from a laser to trap nanoscale particles. The new device creates strong forces more efficiently than traditional optical tweezers and eliminates a problem that caused earlier setups to overheat.  |
