Why size matters for gold as a catalyst

Advanced microscopy study reveals insights into the catalytic activity of gold nanoparticles.

Heat transfer surprise could lead to thermal transistors

As much as 100 times more heat than predicted by the standard radiation theory can flow between two nanoscale objects, even at bigger-than-nanoscale distances.

A pill for delivering biomedical micromotors

Scientists report that they have found a way to encapsulate micromotors into pills. The pill's coating protects the devices as they traverse the digestive system prior to releasing their drug cargo.

Researchers confirm improved theory of atomic nucleus by measuring nuclear radii

Physicists have performed laser spectroscopy on cadmium isotopes to confirm an improved model of the atomic nucleus. It has been developed to describe the exceptional behaviour of the radii of calcium isotopes.

Controlling light at the nanoscale with graphene

Researchers are developing ways to use graphene efficiently in novel optical technologies with potential applications in medical imaging, biosensing, signal processing and computing.

2D atomic crystals probe: how hot it is in a plasmonic 'hotspot'

Scientists have developed a quantitative SERS technique to probe the maximum plasmonic fields before effects such as electron tunneling become dominant.
