Researchers in the Nanofabrication and Devices group at the Argonne National Laboratory, in collaboration with the University of Pennsylvania, Advanced Diamond Technologies Inc., and Innovative Micro Technology, have discovered that defects at the grain boundary in ultrananocrystalline diamond (UNCD) hold primary responsibility for the fundamental mechanism of energy dissipation. http://www.physorg.com/news169309041.html Nanotechnology Wed, 12 Aug 2009 15:30:04 EST news169309041 (PhysOrg.com) -- Scientists at the University of Glasgow have developed the world`s smallest diamond transistor. http://www.physorg.com/news158946763.html Technology Tue, 14 Apr 2009 16:53:11 EST news158946763 Researchers at the McCormick School of Engineering and Applied Science at Northwestern University have developed, characterized, and modeled a new kind of probe used in atomic force microscopy (AFM), which images, measures, and manipulates matter at the nanoscale. http://www.physorg.com/news177073639.html Nanotechnology Tue, 10 Nov 2009 11:08:34 EST news177073639 They call diamonds "ice," and not just because they sparkle. Engineers and physicists have long studied diamond because even though the material is as hard as an ice ball to the head, diamond slips and slides with remarkably low friction, making it an ideal material or coating for seals, high performance tools and high-tech moving parts. http://www.physorg.com/news133446222.html Nanotechnology Mon, 23 Jun 2008 13:23:42 EST news133446222 (PhysOrg.com) -- No longer just an expensive ornament, diamonds are now of a sufficient size and quality to attract the eye of a team of physicists at Macquarie University, who are using them to develop a new more powerful laser. http://www.physorg.com/news148229641.html Physics Thu, 11 Dec 2008 14:54:01 EST news148229641 For centuries, human beings have been entranced by the captivating glimmer of the diamond. What accounts for the stunning beauty of this most precious gem? As mathematician Toshikazu Sunada explains in an article appearing today in the Notices of the American Mathematical Society, some secrets of the diamond's beauty can be uncovered by a mathematical analysis of its microscopic crystal structure. http://www.physorg.com/news118590481.html Other Sciences Thu, 03 Jan 2008 13:48:01 EST news118590481 A recent simulation has shown that thin layers of ice could persist on specially treated diamond coatings at temperatures well above body temperature, which could make ice-coated-diamond films an ideal coating for artificial heart valves, joint replacements, and wear-resistant prosthetics. http://www.physorg.com/news108223161.html Physics Wed, 05 Sep 2007 14:59:21 EST news108223161 (PhysOrg.com) -- Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond. The scientists also calculated that another material, lonsdaleite (also called hexagonal diamond, since it`s made of carbon and is similar to diamond), is even stronger than w-BN and 58 percent stronger than diamond, setting a new record. http://www.physorg.com/news153658987.html Physics Thu, 12 Feb 2009 11:04:13 EST news153658987 (PhysOrg.com) -- Diamond-like carbon films created at Sandia National Laboratories are helping probe the far boundaries of the solar system as part of a NASA mission to study how the sun's solar wind interacts with the interstellar medium - the matter that exists between the stars within a galaxy. http://www.physorg.com/news154022294.html Physics Mon, 16 Feb 2009 15:58:54 EST news154022294 (PhysOrg.com) -- The largest representation ever created of the atomic structure of diamond will be brought to the West End on Tuesday for public exhibition. The sculpture is one of three works of science art portraying carbon made in recent weeks by the University of Keele, and called collectively Carbon Rapture. http://www.physorg.com/news167290123.html Nanotechnology Mon, 20 Jul 2009 06:38:40 EST news167290123 In a recent special issue of Chemical Vapor Deposition devoted to nanodiamonds, editors Amanda Barnard and Oliver Williams note that "the diversity of nanocarbon structures and allotropes has led to a plethora of growth techniques and unique properties, and has opened the door to a number of exciting applications." http://www.physorg.com/news140189177.html Nanotechnology Tue, 09 Sep 2008 14:26:17 EST news140189177 HTC has created a mystery for its announcement of next generation innovations in London on May 6th. Bloggers and Internet electronic gadget web sites have entered into the fray. Is it an Android supported device? Is it mobile Manila? Is it Touch Diamond? Whatever it is, it better be good after all this hype. http://www.physorg.com/news129130539.html Electronics Sun, 04 May 2008 14:35:39 EST news129130539 (PhysOrg.com) -- A team of Brookhaven and Argonne National Laboratory researchers has demonstrated a reliable path for sculpting an intricate x-ray focusing lens out of diamond. Their technique, which was published in the January 2009 edition of the Journal of Synchrotron Radiation, could prove extremely valuable in the study of nanomaterials at future synchrotron light sources. http://www.physorg.com/news168536133.html Nanotechnology Mon, 03 Aug 2009 16:36:13 EST news168536133 (PhysOrg.com) -- Whoever thought that science was a dry subject might change their mind after learning about a new discovery in which tequila is turned into diamonds. A team of Mexican scientists found that the heated vapor from 80-proof (40% alcohol) tequila blanco, when deposited on a silicon or stainless steel substrate, can form diamond films. http://www.physorg.com/news145255770.html Chemistry Fri, 07 Nov 2008 04:49:30 EST news145255770 (PhysOrg.com) -- Tomorrow's lasers may come with a bit of bling, thanks to a new technology that uses man-made diamonds to enhance the power and capabilities of lasers. Researchers in Australia have now demonstrated the first laser built with diamonds that has comparable efficiency to lasers built with other materials. http://www.physorg.com/news172497349.html Physics Fri, 18 Sep 2009 12:56:20 EST news172497349
