Light triggers gold in unexpected way Mechanism to control output of a nanoscale antenna Date: November 30, 2018 Source: Rice University Summary: Researchers have discovered a fundamentally ...

On June 26, an interdisciplinary team of experts led by Professor Justin Chalker at Flinders University in Australia announced a new approach to recovering high-purity gold from various sources.

Gold owes its dazzling lustre to the way it reflects light. But ultra-thin gold flakes can also generate and emit their own light in a process called photoluminescence.

During the past couple weeks, gold has had the Midas Touch. But we are finally seeing some signs of weakness. After reaching an all-time high of $1,814.95, the precious metal is now at $1,739.00.

Electrons reveal light. To image the motion of wavefronts, a team of researchers set up a very clever experiment. First, the surface plasmons were generated in gold using an extremely short pulse ...
