Chemistry puts new sparkle in diamonds

11.02.2004


Diamonds are getting bigger, more colorful and cheaper, thanks to chemistry. A favorite gem at Valentine’s Day is getting a makeover with synthetic diamond making processes, according to the Feb. 2 issue of Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, the world’s largest scientific society.


The diamond-making business has been around for years and although synthetic diamonds had many important uses, including saw blades, drill bits and exfoliants, they were tiny and not gem quality. Only recently has chemistry been able to grow large, gem quality stones at approximately one-third the price of mined diamonds, says C&EN.

Companies such as Gemesis in Florida and Apollo Diamond in Boston are now creating lab-grown diamonds that can be produced to more than a carat in size and are virtually indistinguishable from their mined counterparts, says the newsmagazine. They are chemically and physically true diamonds.

Synthetic diamond-makers start with a tiny diamond "seed" around which the new diamond grows. But that’s not chemistry’s only role in the diamond market. Even natural diamonds can be changed with chemistry, says the newsmagazine.



Colored diamonds, which are valuable and very rare, can be created by introducing carefully controlled elemental "impurities" into the stone, says C&EN. For instance, nitrogen produces a yellow stone. Infusing boron into the growing diamond produces a blue gem.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
