Under an atomic force microscope, the tiny structures look like fragments of nanoscopic pearl necklaces. In reality, the `pearls` are fullerene molecules that are linked together by means of a special fullerene-binding molecule. Spanish researchers describe their method for `threading` these nanopearls in the latest issue of the journal Angewandte Chemie. http://www.physorg.com/news115630716.html Nanotechnology Fri, 30 Nov 2007 07:38:36 EST news115630716 (PhysOrg.com) -- A team led by Manfred Scheer at the University of Regensburg has now synthesized the first example of an inorganic, carbon-free C80 analogue. http://www.physorg.com/news160311135.html Chemistry Thu, 30 Apr 2009 11:54:09 EST news160311135 Virginia Tech chemistry Professor Harry Dorn has developed a new area of fullerene chemistry that may be the backbone for development of molecular semiconductors and quantum computing applications. http://www.physorg.com/news140112239.html Chemistry Mon, 08 Sep 2008 17:03:59 EST news140112239 Virginia Tech chemistry Professor Harry C. Dorn, Emory and Henry College chemistry Professor James Duchamp, and Panos Fatouros, professor and chair of the Division of Radiation Physics and Biology at the Virginia Commonwealth University School of Medicine have co-invented a hands-off process for filling fullerenes with radio-active material. http://www.physorg.com/news166200939.html Nanotechnology Tue, 07 Jul 2009 15:56:45 EST news166200939 Fullerenes, the soccer ball-shaped spheres of carbon that helped usher in the nanotechnology era, have been touted as versatile containers for delivering drugs and other clinically useful molecules to tumors. Turning promise into reality, investigators from the National Cancer Institute`s Cancer Nanotechnology Platform Partnership at Virginia Commonwealth University have developed a new imaging agent that is 40 times more potent at boosting magnetic resonance imaging (MRI) signals than agents currently approved for human clinical use. http://www.physorg.com/news72977097.html Nanotechnology Mon, 24 Jul 2006 16:24:57 EST news72977097 The birth secret of buckyballs -- hollow spheres of carbon no wider than a strand of DNA -- has been caught on tape by researchers at Sandia National Laboratory and Rice University. An electron microscope video and computer simulations show that "shrink-wrapping" is the key; buckyballs start life as distorted, unstable sheets of graphite, shedding loosely connected threads and chains until only the perfectly spherical buckyballs remain. http://www.physorg.com/news112637658.html Nanotechnology Fri, 26 Oct 2007 17:14:18 EST news112637658 An international group of scientists has developed a polymer-based solar cell with an ability not yet seen in similar cells: almost every single photon it absorbs is converted into a pair of electric-charge carriers, and every one of those pairs is collected at the cell's electrodes. http://www.physorg.com/news164458857.html Physics Wed, 17 Jun 2009 12:01:52 EST news164458857 Rice University's Andrew Barron and his group, working with labs in Italy, Germany and Greece, have identified specific molecules that could block the means by which the deadly virus spreads by taking away its ability to bind with other proteins. http://www.physorg.com/news161958048.html Chemistry Tue, 19 May 2009 13:24:04 EST news161958048 Researchers have created a hybrid carbon nanomaterial that merges single-walled carbon nanotubes and spherical carbon-atom cages called fullerenes. The new structures, dubbed NanoBuds because they resemble buds sprouting on branches, may possess properties that are superior to fullerenes and nanotubes alone. They are described in the March 2007 edition of Nature Nanotechnology. http://www.physorg.com/news94478341.html Nanotechnology Fri, 30 Mar 2007 12:59:01 EST news94478341 (PhysOrg.com) -- A new class of economically viable solar power cells--cheap, flexible and easy to make--has come a step closer to reality as a result of recent work at the National Institute of Standards and Technology, where scientists have deepened their understanding of the complex organic films at the heart of the devices. http://www.physorg.com/news168018281.html Physics Tue, 28 Jul 2009 16:45:35 EST news168018281 A world-renowned U.S. scientist says he is plotting a revolution -- a revolution in the way children around the world are taught science. http://www.physorg.com/news88879264.html Other Sciences Wed, 24 Jan 2007 16:41:04 EST news88879264 The energy from sunlight falling on only 9 percent of California`s Mojave Desert could power all of the United States` electricity needs if the energy could be efficiently harvested, according to some estimates. Unfortunately, current-generation solar cell technologies are too expensive and inefficient for wide-scale commercial applications. http://www.physorg.com/news122908304.html Chemistry Fri, 22 Feb 2008 13:11:44 EST news122908304 Fullerenes, also fondly known as buckyballs, are showing an ugly side. Since being discovered in 1985, the hollow carbon atoms have been adapted for nanotechnology and biomedical applications ranging from electronics to carriers of imaging materials. http://www.physorg.com/news126874283.html Nanotechnology Tue, 08 Apr 2008 11:51:23 EST news126874283 `It`s not that there aren`t spin measurement techniques already,` Christoph Boehme tells PhysOrg.com. `The problem is that many of those methods used to date have limited sensitivity.` http://www.physorg.com/news100340059.html Physics Wed, 06 Jun 2007 09:14:19 EST news100340059 Using transparent zebrafish embryos, researchers at Jefferson Medical College have shown that a microscopic nanoparticle can help fend off damage to normal tissue from radiation. The nanoparticle, a soccer ball-shaped, hollow, carbon-based structure known as a fullerene, acts like an "oxygen sink," binding to dangerous oxygen radicals produced by radiation. http://www.physorg.com/news8186.html Nanotechnology Tue, 15 Nov 2005 13:16:14 EST news8186
