Diamonds Are Forever Revealing New Insights into Earth's Development
Diamonds will take center stage this month in countless wedding ceremonies and other celebrations. In addition to their usual role as symbols of enduring love and fidelity, diamonds are now also helping geologists unravel clues about how the earth's precious metal mineralization was formed and why diamonds and some of these metals are found in... 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)
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)
Tiny diamonds on Santa Rosa Island give evidence of cosmic impact
Nanosized diamonds found just a few meters below the surface of Santa Rosa Island off the coast of Santa Barbara provide strong evidence of a cosmic impact event in North America approximately 12,900 years ago. view more (2009-07-22)
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)
Diamonds are a laser's best friend

Diamond by-product of hydrogen production and storage method
There may not be a pot of gold at the end of the rainbow, but there appears to be nanocrystalline diamonds at the end of a process to produce and store hydrogen using anthracite coal. view more (2006-06-26)
X-rays use diamonds as a window to the center of the Earth
Diamonds from Brazil have provided the answers to a question that Earth scientists have been trying to understand for many years: how is oceanic crust that has been subducted deep into the Earth recycled back into volcanic rocks? view more (2008-08-13)
Liquid CO2 drives rapid thrust of diamond-bearing structures
Freeze-dried ice cream looks like the original product, and even tastes pretty good, but "drying" ice cream at room temperature would leave a sour-smelling, sloppy mess. view more (2007-05-03)
Sorting diamonds from toothbrushes: New guide to protecting personal information
Thefts of personally identifiable information (PII), such as social security and credit card account numbers, are increasing dramatically. view more (2009-01-14)
Data mining personnel
With the dark clouds of global recession now is the time for companies to make the most of their most valuable assets - their personnel. Writing in a forthcoming issue of the International Journal of Business Information Systems, researchers in India explain how data mining could help unearth the diamonds in the rough. view more (2008-04-23)
Diamonds may be the ultimate MRI probe, say Quantum physicists
Diamonds, it has long been said, are a girl's best friend. But a research team including a physicist from the National Institute of Standards and Technology (NIST) has recently found that the gems might turn out to be a patient's best friend as well. view more (2009-09-23)
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)

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)
Rensselaer researchers create tiny magnetic diamonds on the nanoscale
Diamonds have always been alluring, but now a team of scientists has made them truly magnetic - on the nanoscale. view more (2005-09-13)
Circumstellar space: Where chemistry happens for the very first time
