Highly charged ions melt nano gold nuggets

Normally, we have to make a choice in physics: Either we deal with big things—such as a metal plate and its material properties, or with tiny things—such as individual atoms. But there is also a world in between: The ...

Real-time imaging of chemical processes

National University of Singapore scientists observe the real-time formation of hollow structures in the galvanic replacement (GR) reaction between silver and gold with nanometre resolution, gaining insights on the mechanisms ...

Relativistic heavy ion collider begins 18th year of experiments

The first smashups of two new types of particles at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy (DOE) Office of Science user facility for nuclear physics research at Brookhaven National Laboratory—will ...

Divalent gold complex isolated for the first time in a pure form

According to textbook knowledge, the usual oxidation states of gold in compounds are +I and +III. The divalent form (+II), on the other hand, prefers to form polynuclear compounds or simply undergoes transformation into the ...

Researcher developing hand-held gold sensor

Instead of a pan and a pick ax, prospectors of the future might seek gold with a hand-held biosensor that uses a component of DNA to detect traces of the element in water.

Super environmentally friendly: the 'fool's gold battery'

High-performance lithium ion batteries face a major problem: Lithium will eventually start to run out as batteries are deployed in electric cars and stationary storage units. Researchers from Empa and ETH Zurich have now ...
