Scientists melt in Gold & # 39; room temperature

Scientists looked at how to melt gold & # 39; room temperature.

An international team & # 39; researchers went on this revelation almost by accident.

Ludvig de Knoop, a postdoc at the University & # 39; Technology & # 39; Chalmers, was just interested to see how the top level & # 39; & # 39 magnification; electronic microscope influence the gold atoms.

"I'm really surprised at the discovery bill," he said, having found that the surface layers were fused – f & # 39; room temperature.

"This is an extraordinary phenomenon, and gives us new knowledge and gold fundattiv," said Knoop.

Using & # 39; computational modeling, the team announce that the thawed surface phase has not been an increase in temperature, but rather flaws in & # 39; high electric fields.

Simply put, the gold atoms become excited.

Think in the field of electricity as the love interest: When very close, the atoms become the language bound, sweaty palmed, and generally flustered losing their orderly structure and release almost all each other links .

"The discovery of & # 39; as the gold atoms can lose their structure with & # 39; this way is not only spectacular, but also scientifically innovative," according to Chalmers.

Along with theoretical Mikael Juhani Kuisma Finnish University & # 39; Jyväskylä, de Knoop & Co. "Opened new avenues in materials science", said the University.

The researchers also found that it is possible to switch between solid and melt structure, you can & # 39; lead to new types of & # 39; sensors, catalysts, transistors and components without contact.

"Because we can master and change of surface atom layers properties, opens doors for different types of & # 39; applications," said co-author Eva Olsson, professor in the Department of Chalmers Physics f & # 39; statement.

Do not expect to initiate criminal enterprise melting gold blocks by increasing the electric field, though.

"I would say that this is not possible," said Knoop said Digital Trends.

The surface melting & # 39; any object larger than a couple nanometers wide & # 39; (Like its golden cone) "requires a voltage not available," he said.

Full details & # 39; the study were published in the journal Materials & # 39; Physical Review.
