(PhysOrg.com) -- First, it was the soccer-ball-shaped molecules dubbed buckyballs. Then it was the cylindrically shaped nanotubes. Now, the hottest new material in physics and nanotechnology is graphene: a remarkably flat molecule made of carbon atoms arranged in hexagonal rings much like molecular chicken wire. http://www.physorg.com/news177689867.html Nanotechnology Tue, 17 Nov 2009 14:22:12 EST news177689867 (PhysOrg.com) -- Physicists have investigated the purest graphene to date, and have found that the material possesses unprecedented high electronic quality. The discovery has raised the bar for this relatively new material, and challenges scientists to find out just how perfect graphene can be. http://www.physorg.com/news174654627.html Nanotechnology Tue, 13 Oct 2009 12:11:02 EST news174654627 Carbon nanoparticles are widely used in medicine, electronics, optics, materials science and architecture, but their health and environmental impact is not fully understood. http://www.physorg.com/news168689442.html Nanotechnology Wed, 05 Aug 2009 11:11:10 EST news168689442 (PhysOrg.com) -- John Spence, a physicist at Arizona State University, is a longtime user of the Advanced Light Source at Lawrence Berkeley National Laboratory, where he has contributed to major advances in lensless imaging. It`s a particularly apt propensity for someone who works with x-rays, since they can`t be focused with ordinary lenses. http://www.physorg.com/news168620492.html Physics Tue, 04 Aug 2009 16:20:01 EST news168620492 In his neatly ordered lab at DuPont, chemist Ming Zheng slides open a glass cabinet and removes a flask of soot that could have been swept from someone's fireplace. http://www.physorg.com/news168613815.html Nanotechnology Tue, 04 Aug 2009 14:11:31 EST news168613815 John Spence, a physicist at Arizona State University, is a longtime user of the Advanced Light Source at Lawrence Berkeley National Laboratory, where he has contributed to major advances in lensless imaging. It's a particularly apt propensity for someone who works with x-rays, since they can't be focused with ordinary lenses. http://www.physorg.com/news168092880.html Physics Wed, 29 Jul 2009 13:28:29 EST news168092880 Scientists at Penn State University, in collaboration with institutes in the US, Finland, Germany and the UK, have figured out the long-sought structure of a layer of C60 - carbon buckyballs - on a silver surface. The results, which could help in the design of carbon nanostructure-based electronics are reported in Physical Review Letters and highlighted in the July 27th issue of APS's on-line journal Physics. http://www.physorg.com/news167912764.html Nanotechnology Mon, 27 Jul 2009 12:30:02 EST news167912764 (PhysOrg.com) -- Graphene is nature's thinnest elastic material and displays exceptional mechanical and electronic properties. Its one-atom thickness, planar geometry, high current-carrying capacity and thermal conductivity make it ideally suited for further miniaturizing electronics through ultra-small devices and components for semiconductor circuits and computers. http://www.physorg.com/news167835039.html Nanotechnology Sun, 26 Jul 2009 14:20:01 EST news167835039 If you're of a certain age, you'll remember Buckminster Fuller's distinctive "geodesic domes" - soccer-ball-shaped structures that the late futurist envisioned as ideal human domiciles. Tel Aviv University chemists remember them too - and are now putting them to use in the treatment of multiple sclerosis (MS). http://www.physorg.com/news156706234.html Nanotechnology Thu, 19 Mar 2009 18:31:13 EST news156706234 (PhysOrg.com) -- New research findings at MIT could lead to microchips that operate at much higher speeds than is possible with today's standard silicon chips, leading to cell phones and other communications systems that can transmit data much faster. http://www.physorg.com/news156698836.html Physics Thu, 19 Mar 2009 16:27:54 EST news156698836 Microscopic particles of carbon known as buckyballs may be able to keep the nation's water pipes clear in the same way clot-busting drugs prevent arteries from clogging up. http://www.physorg.com/news155457592.html Nanotechnology Thu, 05 Mar 2009 06:40:16 EST news155457592 This year's model isn't your father's nanocar.
