A team of scientists have solved the longstanding problem of how electrons move together as a group inside cylindrical nanoparticles.
The new research provides an unexpected theoretical breakthrough in the field of electromagnetism, with perspectives for metamaterials research.
The team of theoretical physicists, from the University of Exeter and the University of Strasbourg, created an elegant theory explaining how electrons move collectively in tiny metal nanoparticles shaped like cylinders.
The work has led to new understanding of how light and matter interact at the nanoscale, aland has implications for the realization of future nanoscale devices exploiting nanoparticle-based metamaterials with spectacular optical properties.

Bacterial nanopores open future of data storage
Bioengineers at EPFL have developed a nanopore-based system that can read data encoded into synthetic macromolecules with higher accuracy and resolution than similar methods on the market. The system is also potentially cheaper and longer-lasting, and overcomes limitations that prevent us from moving away from conventional data storage devices that are rapidly maxing out in capacity and endurance.
