Diamond layer makes steel rock hard
Dutch chemist Ivan Buijnsters from the University of Nijmegen has successfully produced a diamond layer on a steel substrate. This opens up the possibility of wear-resistant tools. The secret to this technique is an adhesive layer between the steel and the diamond layer. Buijnsters made diamond layers by allowing methane gas diluted in hydrogen... view more... (2003-05-16)
Diamond detectors - The Physics Congress 2002
Diamond has an extremely high resilience to radiation - three orders of magnitude higher than silicon - making it an ideal material for detectors that monitor radioactive emissions inside the hostile environments found in nuclear energy plants. But because of the high price of real diamond, synthetic diamond is needed. The latest developments in... view more... (2002-04-02)
Diamonds key to a sparkling listening experience
Music lovers could be in for the ultimate listening experience, thanks to a new range of speakers containing parts made of diamond, writes Marina Murphy in the Chemistry & Industry magazine. The unique properties of diamond make the speakers less susceptible to distortion and thus provide a clearer sound, say their manufacturers Bowers &... view more... (2005-02-18)
£350K Boost for University`s Diamond Technology
Heart operations could soon be safer - thanks to new diamond-like coating technology in development at the University of Ulster. A research team headed by Professor Jim McLaughlin, Dr Paul Maguire and Dr Stephen Morley of the School of Electrical and Mechanical Engineering at the University have been awarded a £350,000 grant for research... view more...

Smithsonian researcher probes Hope Diamond's fiery red glow
A study released in the January 2008 edition of the journal Geology proves that a blue diamond's rare appeal goes far beyond its beauty. The study was conducted by Jeffrey Post, curator of the National Gem Collection and mineralogist, at the Smithsonian's National Museum of Natural History. view more (2008-01-09)
Z machine melts diamond to puddle
Sandia's Z machine, by creating pressures more than 10 million times that of the atmosphere at sea level, has turned a diamond sheet into a pool of liquid. view more (2006-11-06)
A crystal that nature may have missed
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... view more...

Silicon And Diamond
To make super-durable and strong details it is necessary to use so-called diamond composites, i.e. materials (matrixes) with incorporated tiny diamonds. The matrix is to be durable, strong, wear-proof as well as monolithic by structure ensuring chemical interaction with diamonds. To avoid internal tension this matrix must have physical... view more... (2002-09-23)
UCLA scientists design new super-hard material
Ultra-hard materials are used for everything from drills that bore for oil and build new roads to scratch-resistant coatings for precision instruments and the face of your watch. view more (2007-04-23)
UC Santa Barbara researchers light up 'dark' spins in diamond
Researchers at UC Santa Barbara have potentially opened up a new avenue toward room temperature quantum information processing. By demonstrating the ability to image and control single isolated electron spins in diamond, they unexpectedly discovered a new channel for transferring information to other surrounding spins - an initial step towards... view more...

Diamond conference at the Goethe University
From the 10 to 15 August, the casino on the Westend Campus will become the worldwide centre for diamond researchers from industry and academia. During this time, the mineralogists from the GeoZentrum of the Goethe University will host the 9th International Kimberlite Conference, which is the most important meeting related to this unique gemstone. view more (2008-08-12)
Selenium-protein deficiency raises prostate cancer risk
Selenium, an essential dietary mineral that can act as an antioxidant when incorporated into proteins, has been shown in many studies to reduce the incidence of cancers - notably lung, colorectal and prostate. view more (2006-05-23)
Diamonds are a laser's best friend
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. view more (2009-09-21)
University of Pennsylvania Engineers Reveal What Makes Diamonds Slippery at the Nanoscale
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. view more (2008-06-24)
Tough new probe developed for nanotechnologists
Since the invention of the atomic force microscope (AFM) in 1986 by Nobel laureate Gerd Binnig, the tool has been employed to advance the science of materials in many ways, from nanopatterning (dip-pen nanolithography) to the imaging of surfaces and nano-objects such as carbon nanotubes, DNA, proteins and cells. In all these applications, the... view more... (2005-08-11)
Argonne theorist gains new insight into the nature of nanodiamond
The newest promising material for advanced technology applications is diamond nanotubes, and research at the U.S. Department of Energy's Argonne National Laboratory is giving new insight into the nature of nanodiamond. view more (2005-09-12)
Argonne researchers create new diamond-nanotube composite material
Researchers at the U.S. Department of Energy's Argonne National Laboratory have combined the world's hardest known material - diamond - with the world's strongest structural form - carbon nanotubes. view more (2005-08-31)
Hope Diamond's phosphorescence key to fingerprinting
Shine a white light on the Hope Diamond and it will dazzle you with the brilliance of an amazing blue diamond. Shine an ultraviolet light on the Hope Diamond and the gem will glow red-orange for about five minutes. view more (2008-01-08)
Heavier hydrogen on the atomic scale reduces friction
Scientists may be one step closer to understanding the atomic forces that cause friction, thanks to a recently published study by researchers from the University of Pennsylvania, the University of Houston and the U.S. Department of Energy's Argonne National Laboratory. view more (2007-11-05)
WATER HELPS TO FIND DIAMONDS
For many years geologists at the Research Institute of Geological and Geoecological Problems, Cheboksary, have been studying the River Karla region, which includes the south-western part of Chuvashia and a part of the Tatar Republic. The scientists used a new isotope-hydrogeochemical method, while searching for kimberlitic pipes. They achieved... view more... (2002-08-06)
