#Discovery of water-containing gem points to vast oceans beneath the Earth The Earth transition zone is the part of the Earth that exists between the upper and lower mantle.
A group of geologists from the University of Alberta uncovered a water-containing gem that finally confirms this theory:
The tiny gem was an accidental find while the geologists were searching for a completely different mineral.
In fact, they very nearly discarded what appeared as a useless brown diamond (because that how geologists think of diamonds).
This diamond, though, turned out to hold ringwoodite, a mineral we have seen only previously in meteorites,
and not On earth. Fortunately, as with many scientific discoveries, this accident was a happy find.
The mineral, which isn visible to the naked eye, exists deep within the Earth, at least 300 miles beneath its surface, in the transition zone.
Geologists believe that volcanic activity pushed this particular rock up to Earth surface. Having a piece of the Earth transition zone available,
geologists spent several years testing it. Their final results showed that the gem contained 1. 5 percent of its weight in water.
This discovery proves the theory that the Earth transition zone not only contains water but might also contain more water than every surface ocean combined.

#Nanomaterial rivals hardness of diamond An article by Scientific American. It s only a matter of time before a movie villain pulling off the crime of the century needs a cutting tool that is harder than anything else On earth.
Perhaps it s a burglary that involves cutting into a case made of diamond#which,
a material that in many ways resembles diamond. Boron nitride can be compressed into a superhard, transparent form#but unlike diamond and many other materials known for their extreme hardness,
it is based not on carbon but on a latticework of boron and nitrogen atoms. Computer simulations have indicated that a rare crystalline form of boron nitride would resist indentation even better than diamond
if it could be synthesized into large samples, and laboratory experiments have shown that more attainable forms of the stuff already approach the hardness of diamond.
Now a new set of experiments on a nanostructured form of boron nitride have yielded even greater measures of hardness than before.
The new material exceeds that of some forms of diamond, according to the authors of a study reporting the findings in the January 17 issue of Nature.
so that they look like glass and diamond in appearance, Tian says. He and his colleagues determined that those samples had measured a hardness of up to 108 gigapascals#slightly harder than synthetic diamond

gauges how a material responds to pressure from the point of a pyramid-shaped piece of diamond called an indenter.
As increasing force (as measured in newtons) is applied to the diamond pyramid, the material s ability to resist indentation levels off at its so-called asymptotic value (as measured in gigapascals).
But the test is predicated on the idea that the diamond will do the indenting, and not the other way around."
In some respects, such as stability at high temperatures, boron nitride is superior to diamond. More from Scientific American. As such, she notes,

#Glowing diamonds make great thermometers Diamonds are known for many things: hardness, luster, and their reputation for being a irl best friend.
But the gems have important scientific uses, too. New research suggests that a certain type of artificial diamond can be used as a nanoscale temperature probe with unmatched precision over time
and space. think this work is a real advance, says materials scientist Daniel Jaque at the Autonomous University of Madrid,
who was involved not in the study. t a good paper on a hot topic. he tiny diamond probes can measure temperatures ranging from 120 K to 900 K (53°C to 627°C) s cold
Scientists discovered the properties of the probeseported in the current issue of Applied Physics Lettershen they set out to investigate a unique defect in diamonds grown using nickel precursors.
The technique incorporates some nickel atoms into the diamond crystal structure, forming what is called an 3 defect center.
Like many other diamond defects, the S3 center emits a glow when struck by a pulse of laser light.
As the temperature drops, the diamond glows for longer periods of time. Luminescent temperature probes aren a totally new idea,
here are many kinds of impurities in diamond, and this particular defect was the most interesting.
This difference makes the nickel-doped diamond luminescence extremely sensitive to fluctuations in temperature. Researchers say the diamond probes could be used for a wide range of applications
but Jaque suspects theyl be most useful for observing the nanoscopic world, in particular the minute temperature fluctuations in living cells.
since the visible light emitted by the diamond probes faint green glowoes not penetrate whole human tissue very well. nly infrared light can penetrate into your body.
Current techniques rely on growing diamonds with a nickel precursor and hoping the defects show up. e do not know how to prepare it.
We just collect it from many diamonds, and some of them have this effect. It a long path
but a more refined approach might allow researchers to standardize the size of diamond particles

Chemical modelling suggests pressure deep inside the planets would crush it into a rain of diamond chips

Our experiment provides the first actual data of diamonds under such high pressure says Ray Smith at the Lawrence Livermore National Laboratory in California.
Using the National Ignition Facility (NIF) at Livermore Smith's team bombarded tiny targets with 176 laser beams to put the squeeze on diamond.
The team fixed a diamond inside a hole cut in a small gold cylinder and then precisely timed laser pulses to strike the cylinder's interior walls.
During that short time the team was able to squeeze diamond to pressures of up to 5 terapascals about 50 million times the atmospheric pressure On earth's surface.
The team's data can now be used to improve models of gas giants and the suspected diamond in their depths.
Nikku Madhusudhan at the University of Cambridge says the results can also aid our understanding of the insides of diamond planets.

Already, perovskite-based photovoltaic cells have achieved power-conversion efficiency of more than 19 percent, which is close to that of many commercial silicon-based solar cells.
