Efficiency of water electrolysis doubled

Researchers have boosted the efficiency of water electrolysis. They applied a layer of copper atoms in a conventional platinum electrode. Thus, reaction intermediates could desorb a bit more easily from the catalyst surface. ...

Copper clusters capture and convert carbon dioxide to make fuel

Capture and convert—this is the motto of carbon dioxide reduction, a process that stops the greenhouse gas before it escapes from chimneys and power plants into the atmosphere and instead turns it into a useful product.

Engineers find a simple yet clever way to boost chip speeds

A typical computer chip includes millions of transistors connected with an extensive network of copper wires. Although chip wires are unimaginably short and thin compared to household wires both have one thing in common: ...

Copper atoms bring a potential new battery material to life

Lithium-ion batteries are an important component of modern technology, powering phones, laptops, tablets and other portable devices when they are not plugged in. They even power electric vehicles. But to make batteries that ...

Finding the 'heart' of an obstacle to superconductivity

A team at Cornell and Brookhaven National Laboratory has discovered that previously observed density waves that seem to suppress superconductivity are linked to an electronic "broken symmetry," offering an important clue ...

Forest of carbon nanotubes (w/ Video)

This image shows a 'forest' of carbon nanotubes – thousands upon thousands of tiny rolls of carbon atoms, grown on a scrap of copper foil. James Dolan explains how easy it is to run across beautiful scenery such as this ...

Two-proton bit controlled by a single copper atom

Just a single foreign atom located in the vicinity of a molecule can change spatial arrangement of its atoms. In a spectacular experiment, an international team of researchers was able to change positions of the nuclei of ...

Copper shock: An atomic-scale stress test

(Phys.org) —Scientists used the powerful X-ray laser at the U.S. Department of Energy's SLAC National Accelerator Laboratory to create movies detailing trillionths-of-a-second changes in the arrangement of copper atoms ...

Elastic to plastic: High-energy lasers warp copper—permanently

The exact pressure that permanently changes copper crystals has been pinpointed, according to a study released today. The findings, published in the journal Science, show that when copper is compressed the microscopic building ...

Building bridges between nanowires

Place a layer of gold only a few atoms high on a surface bed of germanium, apply heat to it, and wires will form of themselves. Gold-induced wires is what Mocking prefers to call them. Not 'gold wires', as the wires are not ...
