		The discovery of the buckyball is an inspiring story of perseverance and dogged determination, reminiscent of the "golden age" of discovery, fraught with dead ends and false leads.
		Either that, or the buckyballs could be compressed and held, which could take the place of industrial diamonds, as a compressed buckyball is at least twice as rigid as diamond.
		The buckytube is an elongated fullerene, hollow in the center as the buckyball.

	Type of buckyball shown to cause brain damage in fish
		Buckyballs are pure carbon structures shaped like soccer balls that differ from other forms of pure carbon, like diamond and graphite, in the way their atoms are bonded.
		Buckyballs show promise as components of fuel cells, drug delivery systems and cosmetics that delay aging.
		A few animal studies have shown that nano-sized particles are capable of moving into the brain after being inhaled, but the current study is believed to be the first to show that the particles can actually cause damage to the brain, Oberdörster says.

	Dynamic Jahn–Teller Effect in Buckyball Cations
		Buckyballs joined diamond and graphite in the 1980s as the third known form of pure carbon.
		) familiarly known as buckyballs a particular example of a distortion with the jargon name "dynamic Jahn–Teller effect." Buckyball ions are of interest to scientists partly because it appears that properties such as superconductivity (resistanceless flow of electricity) in solids comprising loosely bound collections of buckyballs are closely related to the structure of isolated ions.
		The Jahn–Teller effect in buckyball cations is associated with the breakdown of the widely used Born–Oppenheimer approximation that allows theorists to calculate the electronic and vibrational states separately with any interaction between the two systems treatable as a small perturbation.

		The findings came as something of a surprise, despite earlier studies that have shown buckyballs to be toxic to cells unless coated and to be able to find their way into the brains of fish.
		Before these cautionary discoveries, researchers thought that the combination of buckyballs’ dislike of water and their affinity for each other would cause them to clump together and sink to the bottom of a pool, lake, stream or other aqueous environment.
		The researchers found that buckyballs docked on the minor groove of “A” DNA, bending the molecule and deforming the stacking angles of the base pairs in contact with it.

	Transistors Made From Single Carbon-60 Buckyballs
		The first transistors to be fashioned from a single "buckyball" -- a molecule of carbon-60 -- have been reported by scientists with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley.
		Taking advantage of a phenomenon that is largely viewed as a problem by the electronics industry, the team of Berkeley Lab and UC Berkeley researchers created a separation between two gold electrodes that was about one nanometer (one billionth of a meter) across.
		Buckyballs are so tiny that, as transistors, they only permit one electron at a time to move through them.

	Doping Buckyballs With Atoms, One at a Time
		By adding potassium atoms to familiar soccer-ball-shaped "buckyballs," Crommie and his coworkers can increase the electric charge on each C60 molecule; individual potassium atoms are either attached or removed from a C60 molecule using the tip of an STM.
		As a buckyball acquires potassium-atom dopants the energy state of its molecular orbitals shifts, causing the doped molecule to "light up" in the STM image.
		By then moving the buckyball over an impurity in the silver surface (most likely an oxygen atom), the potassium atoms could be "pulled off" one at a time.

	Buckyball
		Buckyball is a member of a class of carbon structures called fullerenes.
		Fullerenes can be hollow spheres like buckyball, ellipsoid, or tubes (buckytubes).
		Fullerenes are similar in structure to graphite, which is composed of a sheet of linked hexagonal rings, but they contain pentagonal (or sometimes heptagonal) rings that prevent the sheet from being planar.

		Within a year or two of the discovery of buckyballs by Smalley and his associates, there were hundreds of people working on them in labs all over the world.
		But before they started working on buckyballs, all of these people were working on something else, something that they believed was important (or at least, something that they told the funding agencies was important).
		It's also happening in universities, which, despite their mandate to preserve traditional areas of investigation whenever these have value, are rushing to throw their own resources at genomics-based initiatives, to the serious neglect of 'older' subjects that are less fashionable.

	Rice finds 'on-off switch' for buckyball toxicity
		Buckyballs, whose chemical notation is C60, are hollow, soccerball-shaped molecules containing 60 carbon atoms.
		While buckyballs show great promise in applications as diverse as fuel cells, batteries, pharmaceuticals and coatings, some scientists and activists have raised concerns about their potential toxicity to humans and animals.
		For example, the undecorated buckyballs showed the highest toxicity -- about 20 parts per billion-- while the least toxic proved to be buckyballs decorated with the largest number of hydroxyl side-groups.

	Nifty 50: BUCKY BALLS
		Buckyballs, developed by NSF-funded researchers in 1985, are a form of carbon-composed clusters of 60 carbon atoms, bonded together in apolyhedral, or many-sided structure composed of pentagons and hexagons, like the surface of a soccer ball.
		The molecule, also called "buckministerfullerene," is named after U.S. architect Richard Buckminster Fuller (1895-1983) because of the resemblance of the structure to the geodesic dome, which Fuller invented.
		Potential applications of buckyballs or "buckytubes" are as circuit elements in nanoelectronic devices and/or molecular electronics.

	What is a Buckyball?
		The smallest buckyball consists of 20 carbon atoms, and one of the largest has 540, though even larger variants are likely to be discovered or manufactured.
		Although there have been questions about the safety of the buckyball to marine animals, it is known that fullerenes are largely inert and the evidence against their reactivity is much higher than that in favor of it.
		The most common production method for buckyballs is to situate a block of graphite between two electrodes and send a charge through the block.

		To learn more about buckyballs and how they are formed, researchers began to look for naturally occurring fullerenes, particularly on the earth.
		The shungite fullerenes are notable not only for their earthly origin, but also because they may have been formed as solids--most laboratory-created fullerenes are grown in the gas phase.
