2,000-year-old statue of an athlete sheds light on corrosion and other modern challenges

Crystal Growth & Design

The restoration of a 2,000-year-old bronze sculpture of the famed ancient Greek athlete Apoxyomenos may help modern scientists understand how to prevent metal corrosion, discover the safest ways to permanently store nuclear waste, and understand other perplexing problems.

That's the conclusion of a new study on the so-called "biomineralization" of Apoxyomenos appearing in the current issue of ACS' Crystal Growth & Design, a bi-monthly journal. Best known as "The Scraper," the statue depicts an athlete scraping sweat and dust from his body with a small curved instrument.

In the report, Davorin Medakovic and colleagues point out that Apoxyomenos was discovered in 1998 on floor of the Adriatic Sea. While the discovery was a bonanza for archaeologists and art historians, it also proved to be an unexpected boon to scientists trying to understand biomineralization. That's the process in which animals and plants use minerals from their surroundings and form shells and bone. Apoxyomenos was encrusted with such deposits.

"As studies of long-term biofouled manmade structures are limited, the finding of an ancient sculpture immersed for two millennia in the sea provided a unique opportunity to probe the long-term impact of a specific artificial substrate on biomineralizng organisms and the effects of biocorrosion," the report said. By evaluating the mineral layers and fossilized organisms on the statue, the researchers were able to evaluate how underwater fouling organisms and communities interacted with the statue as well as how certain mineral deposits on the bronze sculpture slowed its deterioration.

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
