New dynamic probes for ions interacting with biomolecules

Pairs of negatively charged phosphate groups and positive magnesium ions represent a key structural feature of DNA and RNA embedded in water. Vibrations of phosphate groups have now been established as selective probes of ...

Building better batteries by borrowing from biology

A research team at Osaka University has reported a new advance in the design of materials for use in rechargeable batteries, under high humidity conditions. Using inspiration from living cells that can block smaller particles ...

Recording the birth of a nanoplasma

An international team of researchers has successfully recorded the birth of a nanoplasma for the first time. In their paper published in the journal Physical Review Letters, the group describes how they pulled off this feat ...

Cracking the mystery of perfect superconductor efficiency

In 1911, physicist Heike Kamerlingh Onnes aimed to lower mercury's temperature to as close to absolute zero as possible. He hoped to win a disagreement with Lord Kelvin, who thought metals would stop conducting electricity ...

New electrode for ion concentration analysis

For the purpose of blood analyses and industrial tests, it is often necessary to measure the concentration of specific ions. At present, the relevant devices are large and cannot be produced at low costs. A new dry electrode ...

New technique for 'seeing' ions at work in a supercapacitor

Researchers from the University of Cambridge, together with French collaborators based in Toulouse, have developed a new method to see inside battery-like devices known as supercapacitors at the atomic level. The new method ...
