The diamond rose 700 km from Earth’s mantle to the surface.
Apparently, something is rusting at 550 km below the surface.
Yes, on some planets it rains diamonds!
Diamonds are a geologist’s best friends.
Water isn’t only skin deep.
Data is a girl’s best friend.
These set of rings/disks that are formed in the exhaust plume are known as Shock Diamonds or Mach discs (and by many more names).
To make diamonds, the industry typically resorts to subjecting graphite to immense pressure and temperature, which makes production volumes low and costly. This paradigm is about to change, since researchers at North Carolina State University found a new phase for carbon called Q-carbon, produced at ambient temperatures and pressure. This is surprisingly close to diamond in structure, with the added benefit of exhibiting a couple of unique properties.
Do you fancy diamonds? If the answer is ‘yes’, then you’ll absolutely love this rock extracted from a Russian mine. The rock is littered with over 30,000 diamonds, something which is extremely rare and may yield valuable information about how diamonds form in natural conditions. What’s unlucky for gem sellers was very fortunate for researchers – because the tiny diamonds
For the first time, scientists at Penn State University have coaxed carbon-containing molecules to form a strong tetrahedron shape, then linked each tetrahedron end to end to form a long, thin nanothread. The resulting materials is stronger than carbon nanotubes, while the thread is only a few atoms across thick, hundreds of thousands of times smaller than an optical fiber. This sort
Temperature is an important physical parameter which greatly influences a system. Monitoring and/or manipulating this state parameter with great accuracy is thus of great importance to scientists. Recently, researchers part of DARPA’s Quantum-Assisted Sensing and Readout (QuASAR) program proved a new technique that allowed them to measure and control temperatures at the nanometer scale inside living cells. Measuring temperatures at such fine spatial
Russia announced the declassification of a huge diamond deposit, twice as hard as average ones, and about 10 times bigger than the global supply available today. The sensational announcement was made by Novosibirsk scientists of the Institute of Geology and Mineralogy at the Siberian Branch of the Russian Academy of Sciences and it could detonate the entire global diamond market.
Diamonds are for a nano-second – in the glitter of a candle light, that is. In a stroke of brilliance, Professor Wuzong Zhou, Professor of Chemistry at the University of St Andrews, has found millions of diamond nano-particles in the flickering light of a simple candle. Since its invention in China thousands of years ago, people have always been fascinated
Twinkle, twinkle, little star, How I wonder what you are! Up above the world so high, Like a diamond in the sky! Well maybe the title is a bit far fetched, but I’m really stoked to find out about such a thing; the star in case, BPM 37093 is a variable white dwarf star that consists entirely of crystallized carbon,
For a lot of time man kind or at least a big part of it has been absolutely fascinated with the diamond and its fantastic glimmer. The reasons which account for its stunning beauty could be uncovered by a mathematical analysis of its microscopic crystal structure. It turns out that this structure has some very special, and especially symmetric, properties.
