Diamonds from outer space — Geologists discover origin of Earth's mysterious black diamonds
If indeed "a diamond is forever," the most primitive origins of Earth's so-called black diamonds were in deep, universal time, geologists have discovered. Black diamonds came from none other than interstellar space.   view more (2007-01-10)

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)

Durham diamond expert reports to the White House
The US Government has called in a University of Durham geologist for advice on diamonds in an effort to crack down on the illegal gems-for-arms trade. Dr Graham Pearson is one of a group of international experts and government representatives invited tot he White House Diamond Conference, convened... view more (2001-01-16)

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... view more (2008-06-13)

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... 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... view more (2008-08-12)

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)

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)

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... view more (2008-04-23)

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,... view more (2008-06-24)

Scientists levitate diamond, lead and platinum
Scientists at The University of Nottingham have successfully levitated diamond and some of the heaviest elements, including lead and platinum.   view more (2005-05-11)

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... 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
Picture a cool place, teeming with a multitude of hot bodies twirling about in rapidly changing formations of singles and couples, partners and groups, constantly dissolving and reforming.   view more (2007-08-01)

Putting the squeeze on nitrogen for high energy materials
Nitrogen atoms like to travel in pairs, hooked together by one of the strongest chemical bonds in nature. By subjecting nitrogen molecules to extreme temperatures and pressures scientists are getting a new understanding of not only nitrogen but other similar molecules, including hydrogen.   view more (2008-09-04)

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)

Nanoengineers mine tiny diamonds for drug delivery
Northwestern University researchers have shown that nanodiamonds -- much like the carbon structure as that of a sparkling 14 karat diamond but on a much smaller scale -- are very effective at delivering chemotherapy drugs to cells without the negative effects associated with current drug delivery... view more (2007-10-15)

Laser-induced shocks in diamond anvil can achieve pressures inside supergiant planets
Combining diamond anvils and powerful lasers, laboratory researchers have developed a technique that should be able to squeeze materials to pressures 100 to 1,000 times greater than possible today, reproducing conditions expected in the cores of supergiant planets.   view more (2007-05-03)

Researchers locate mantle's spin transition zone, leading to clues about Earth's structure
Researchers have located the spin transition zone of iron in Earth's lower mantle, a discovery which has profound geophysical implications.   view more (2007-09-24)

UCSB researchers show how to make polymeric micro- and nanoparticles
Researchers in the College of Engineering at UC Santa Barbara have discovered how to make polymeric micro- and nanoparticles in a wide variety of different shapes and sizes using commonly-available lab chemicals and equipment.   view more (2007-07-10)

No Core In Volcanoes
A hot debate in the Earth Sciences is finally resolved in this week's issue of Nature. Researchers from the Department of Earth Sciences at Bristol University show that large volcanoes do not contain material from the Earth's core. This overturns previous theories that conflicted with models of how... view more (2004-01-12)

Alloy of hydrogen and oxygen made from water
Water, the only indispensable ingredient of life, is just about the most versatile stuff on Earth. Depending on its temperature we can heat our homes with it, bathe in it, and even strap on skates and glide across it, to name only the most common of its many forms. When subjected to high pressures,... view more (2006-10-27)

Minerals go 'dark' near Earth's core
Minerals crunched by intense pressure near the Earth's core lose much of their ability to conduct infrared light, according to a new study from the Carnegie Institution's Geophysical Laboratory.   view more (2006-05-26)
