#Microwave diamonds':'Girl's new best friend The 2. 62 carat diamond Calvin Mills bought his fiancee in November is a stunner.
Pear-shaped and canary-yellow, the gem cost $22, 000-a bargain. Mills, the chief executive officer of CMC Technology Consulting in Baton rouge, La.
says he could have spent tens of thousands more on a comparably sized diamond mined out of the earth,
but his came from a lab ."I got more diamond for less money, "says the former Southern University football player. who proposed last year at halftime during one of his alma mater's games at the Superdome in New orleans
. While man-made gems make up just a fraction of the $80 billion global diamond market, demand is increasing as buyers look for cheaper stones that are cheaper-and free of ethical taint.
Human-rights groups, with help from Hollywood have popularized the term"blood diamonds"to call attention to the role diamond mining has played in fuelling conflicts in Africa.
Unlike imitation diamonds such as cubic zirconia, stones that are grown"(the nascent industry's preferred term) in labs have the same physical characteristics and chemical makeup as the real thing.
They're made from a carbon seed placed in a microwave chamber with methane or another carbon-containing gas and superheated into a glowing plasma ball.
That creates particles that crystallize into diamonds, a process that can take 10 weeks. The technology has progressed to the point that experts need a machine to tell synthesized gems apart from those extracted from mines or rivers.

if they get a diamond from above the ground or in the ground, do they really care?"
"asks Chaim Even-Zohar, a principal at Tacy, an industry consulting firm in Ramat Gan, Israel.
In a survey by Gemdax, an Antwerp-based consultant, only 45%of North american consumers from 18 to 35 said they prefer natural diamonds."
"Some substitution for natural diamonds is inevitable, "says Anish Aggarwal, a partner at the firm,
The companies that dominate the market for natural gems, including Russia's Alrosa and De beers,
a unit of London-based Anglo American, don't see it the upstarts as much of a threat,
says Neil Koppel, the CEO of Renaissance Diamonds. His company, in Boca raton, Fla. is supplying Helzberg stores in 10 US cities.
Last year only about 3, 60,000 carats of man-made diamonds were produced, compared with 146 million carats of natural gems mined in 2013, estimates researcher Frost & Sullivan.
The Supply of lab-grown stones will probably jump to 2 million carats in 2018 and 20 million by 2026."
"The value of a diamond is linked inextricably to the inspirational and unique narrative that lies behind each one, from its formation to its history to its emotional significance,

which GEMS can be employed for biomedical uses.""That would require, among other things, further miniaturization.
The 0. 5 to 2 m diameter GEMS in the experiments are already small enough for many in vitro and other possible non-biological applications,
One of the most significant features of GEMS is that they can be tuned"in fabrication to respond to different biochemical states
respectively So placing two different populations of GEMS at the same site makes it possible to track changes in two different variables at the same time--a capability the researchers demonstrated by placing GEMS with two different dimensions in the same location and detecting
Functionally, the GEMS in the current effort are advanced more in that they change their shape in response to stimuli;

#Umbrella-shaped diamond nanostructures make efficient photon collectors Standard umbrellas come out when the sky turns dark,
Inspired by recent work to enhance the luminescence from diamond nanopillar structures, a team of researchers in Japan has discovered that"umbrella-shaped"diamond nanostructures with metal mirrors on the bottom are more efficient photon collectors than their diamond nanostructure"cousins"of other shapes.
By tweaking the shape of the diamond nanostructures into the form of tiny umbrellas, researchers from Tokyo Institute of technology experimentally showed that the fluorescence intensity of their structures was three to five times greater than that of bulk diamond.
They report their results in the journal Applied Physics Letters, from AIP Publishing. To get started, the team formed the umbrella-shaped diamond nanostructures by using an original"bottom-up"fabrication technique that relies on selective and anisotropic growth through holes in a metal mask.
The metal mask also serves as a mirror that is self-aligned to the diamond nanostructures."
"Our umbrella-shaped nanostructure has an effect similar to a solid immersion lens, which reduces the chance of total reflection on its upper surface
and focuses the emitted light toward the'upside'of the structure, "explained Mutsuko Hatano, a professor in the Graduate school of Science and Engineering's Department of Physical Electronics at Tokyo Institute of technology.
"Umbrella-shaped diamond provides significantly better photon collection efficiency than bulk diamond or its pillar-shaped diamond counterpart,
The significance of the team's discovery is that they've shown that the brighter fluorescence intensity of umbrella-shaped diamond nanostructures can be achieved by improving the photon collection efficiency of the nitrogen vacancy centers,
which are the numerous point defects in diamonds that happen to boast the property of photoluminescence.
These properties make nitrogen vacancy centers in diamonds candidates for next-generation spin-based quantum devices such as magnetometers, quantum computers,
Due to the high refractive index (2. 4) of diamond, the photon collection efficiency from the nitrogen vacancy centers in bulk diamond is low."
"In other words, diamond works as an effective light waveguide in low-refractive-index environments,"said Hatano. In terms of applications, the team's nanostructures may find use in highly sensitive magnetic sensors for making biological observations or within the computational science realm for quantum computing and cryptographic communications.

#This new high-power diamond laser can cut steel Although lasers based on diamond have been around around for several years,
they have never been very powerful. That beginning to change now as new CVD fabrication methods provide larger,
and purer, diamonds. Researchers from the Fraunhofer Institute for Applied Optics in Germany, and the MQ Photonics Research Centre in Australia, have built just a diamond laser with 20 times more power than anything yet to date.
The ability to slice through steel has always been the benchmark for cutting power. With 380 Watts@1240nm, the new laser has enough oomph to handle the job.
Diamond optics can not only handle the heat, but can also transfer it away from the hot zone faster that just about anything else.
The new diamond lasers make use of something known as Raman conversion to shift light to wavelengths that are long enough to be absorbed efficiently by steel.
with many noting that the new diamond laser is equal to 00,000 laser pointers. In light of the ample variance in both wavelength and power of pointer devices, those kinds of comparisons should probably be taken as rough.
Diamond lasers can potentially unleash more than just new cutting or machining technologies. Since silicon doesn reflect x-rays
Diamond-based x-ray lasers, on the other hand, would be a whole new ball game. CVD diamond still has its costs,
but they are rapidly falling while output quality is rising. It would seem that these trends should soon make off-the-shelf diamond lasers fairly commonplace a
#Accidental nanoparticles could let lithium ion batteries live another day A new study from MIT could keep lithium ion battery technology on the track for another few laps,
scientists discovered that the main reason lithium ion batteries lose their capacity over many charge-discharge cycles has to do with expansion and contraction of the graphite electrodes at either end.
This expansion problem is one of the reasons graphite has been used for so long since it undergoes relatively little change throughout the battery use.
In particular, aluminum has been a frequent candidate to replace graphite, but tends to get discarded because it expands
which enabled researchers to find telltale signs of hydrated minerals on streaked-looking slopes. These dark, narrow,

The lithium-ion batteries in our phones, tablets and laptops store their energy-carrying ions inside negative electrodes made of graphite.
Lithium could store about 10 times more energy per unit weight than graphite, but it's prone to short-circuiting and catching fire;
silicon and tin could also vastly outperform graphite, but only if the battery is charged at a slow rate,
like lithium or silicon, can store much more energy per unit weight than conventional graphite.
While standard graphite can store approximately 0. 35 ampere-hours per gram (Ah/g), the new electrode can reportedly store over three times as much energy per unit mass (1. 2 Ah/g) at a normal charging rate.
