Asteroid impact made hail of carbon beads Bloomington, Ind. (UPI) May 5, 2008 
A U.S.-led team of scientists says the asteroid impact thought to have killed the dinosaurs hit with such force that carbon deep in the Earth's crust liquefied.
The researchers said they believe the liquid carbon rocketed skyward and formed tiny airborne beads that blanketed the planet. The team of U.S., U.K., Italian and New Zealand researchers said those beads, known as carbon ... read more |

Researchers Make History With All-Carbon Nanotube Radio
Baltimore MD (SPX) Feb 05, 2008Northrop Grumman and the University of Illinois at Urbana-Champaign have created the first fully-functional, all-carbon nanotube transistor radio, demonstrating that carbon nanotubes can be used as high-speed transistors, while consuming only one-thousandth the power required by current transistor technology. "Leading researchers have long theorized that carbon nanotube transistors possess ... more Buckyball Birth Observed By Sandia Nanotech Researcher 
Albuquerque NM (SPX) Nov 27, 2007Almost everyone in the scientific community has heard of buckyballs, but no one until Sandia's Jianyu Huang has seen one being born. Buckyballs - more formally known as buckminsterfullerene C-60 - are carbon-linked nanostructures named for their resemblance to the geodesic dome macrostructures favored for their strength by environmentalist Buckminster Fuller. In addition to the strength ge ... more High-Performance Transistors Produced From Carbon 60 
Atlanta GA (SPX) Nov 27, 2007Using room-temperature processing, researchers at the Georgia Institute of Technology have fabricated high-performance field effect transistors with thin films of Carbon 60, also known as fullerene. The ability to produce devices with such performance with an organic semiconductor represents another milestone toward practical applications for large area, low-cost electronic circuits on flexible ... more Bouncing Bucky Balls 
Bologna, Italy (SPX) Oct 17, 2007C60 molecules have an intriguing ball-shaped structure that suggests several interesting possibilities for motion on surfaces. Indeed, researchers have found that the passage of electrons through a bucky ball in a transistor is correlated to the spinning of the ball around its center of mass. Moreover, since bucky balls look like molecular ball bearings, it has been thought that they may be usef ... more The Original Nanoworkout - Helping Carbon Nanotubes Get Into Shape 
Troy NY (SPX) Jun 11, 2007Researchers at Rensselaer Polytechnic Institute have developed a new method of compacting carbon nanotubes into dense bundles. These tightly packed bundles are efficient conductors and could one day replace copper as the primary interconnects used on computer chips and even hasten the transition to next-generation 3-D stacked chips. Theoretical studies show that carbon nanotubes, if packed ... more |

Berlin, Germany (SPX) Feb 09, 2007Since their discovery in the early 1990s, carbon nanotubes and carbon nanofibers-tiny structures made of pure carbon-have been used in a wide variety of applications. They have become indispensable in the nanosciences and nanotechnology. However, because their production on an industrial scale remains expensive, their commercial use in such areas as catalysis has remained unthinkable. This ... more Geologists Discover Origin Of Mysterious Black Diamonds 
Upton NY (SPX) Jan 15, 2007If indeed "a diamond is forever," the most primitive origins of Earth's so-called black diamonds were in deep, universal time, geologists have discovered. Black diamonds came from none other than interstellar space. In a paper published online on December 20, 2006, in the journal Astrophysical Journal Letters, scientists Jozsef Garai and Stephen Haggerty of Florida International University, alon ... more Resilient Form Of Plant Carbon Gives New Meaning To Term 'Older Than Dirt' 
Seattle WA (SPX) Nov 27, 2006A particularly resilient type of carbon from the first plants to regrow after the last ice age - and that same type of carbon from all the plants since - appears to have been accumulating for 11,000 years in the forests of British Columbia, Canada. It's as if the carbon, which comes from the waxy material plants generate to protect their foliage from sun and weather, has been going into a bank a ... more Buckyballs Make Room For Gilded Cages 
Richland WA (SPX) May 17, 2006Scientists have uncovered a class of gold atom clusters that are the first known metallic hollow equivalents of the famous hollow carbon fullerenes known as buckyballs. The evidence for what their discoverers call "hollow golden cages" appeared today in the online early edition of the Proceedings of the National Academy of Sciences. The fullerene is made up of a sphere of 60 carbon (C) ato ... more Matchbox-Size Nano-Projector Engine For Mobile Apps 
Taunton MA (SPX) Jan 5, 2006Kopin and ExPlay have announced that they are in development of an ultra-small nano projector based on an ultra-high-efficiency version of Kopin's microdisplay, which is being specifically designed for the nano projector, and ExPlay's unique optical technology. Under the $2.2 million program partially funded by the BIRD Foundation, Kopin and ExPlay are developing a matchbox-size projection e ... more |

Woods Hole MA (SPX) Dec 13, 2005Researchers have known for some time that a long, fibrous coil grown by a single-cell protozoan is, gram for gram, more powerful than a car engine. Now, researchers at Whitehead Institute - together with colleagues at MIT, Marine Biological Laboratory in Woods Hole, MA, and University of Illinois, Chicago - have found that this coil is far stronger than previously thought. In addition, the r ... more Clear Hard Nano Based Coatings
New York (UPI) Dec 13, 2005A transparent coating loaded with particles only nanometers or billionths of a meter in diameter is far harder than other conventional organic coatings on the market, for potential use in everything from iPods and cell phones to car windows and flexible video displays, experts told UPI's Nano World. Akron, Ohio-based Ecology Coatings has developed a new coating for polycarbonate plastics. Po ... more Computer Simulation Shows Buckyballs Deform DNA 
Nashville TN (SPX) Dec 07, 2005Soccer-ball-shaped "buckyballs" are the most famous players on the nanoscale field, presenting tantalizing prospects of revolutionizing medicine and the computer industry. Since their discovery in 1985, engineers and scientists have been exploring the properties of these molecules for a wide range of applications and innovations. But could these microscopic spheres represent a potential envi ... more Nanoparticles Set To Seek Out And Destroy Bad Cells 
New York (UPI) Dec 06, 2005A new method to develop collections of nanoparticles that each seek out different cell types could help scientists to better spot tumors before they grow or to deliver medicines to precise targets, experts told UPI's Nano World. Interventional radiologist Ralph Weissleder at Harvard Medical School and his colleagues are developing nanoparticles that can emit either magnetic or optical signal ... more Titania Nanoparticles Could Lead To Improved Sensors And Solar Energy 
Los Angeles CA (SPX) Dec 06, 2005Time evolution of the thermal properties during dehydration of sol-gel titania emulsions Nanostructured titania (TiO2) has been extensively studied as a very promising material for applications in sensors, photocatalysis, solar energy conversion and optical coatings. As the properties of titania are determined by its different phases (i.e. rutile and anatase) and these phases depend upon the ... more
