Neutrinos are a type of particle that pass through just about everything in their path from even the most distant regions of the universe. The giant IceCube experiment at the South Pole can detect when there is a collision between neutrinos and atoms in the ice using detectors. New research results from the Niels Bohr Institute have measured the neutrinos and calculated some of the physical properties of the otherwise exotic and poorly understood particles.
Engineers bring perfectly secure information exchanges one step to reality. They have now designed the first all-photonic quantum repeaters -- protocols that ensure data can be carried reliably and securely across longer distances when using quantum cryptography.
In a move that could improve the energy storage of everything from portable electronics to electric microgrids, researchers have developed a novel X-ray imaging technique to visualize and study the electrochemical reactions in lithium-ion rechargeable batteries containing a new type of material, iron fluoride.
A team of researchers has established a theoretical framework to understand the elastic and electronic properties of graphene. Graphene, a single-atom-thick sheet of carbon atoms arranged in a honeycomb-like lattice, is one of the simplest materials with unrivalled mechanical and electronic properties. The material has been hailed by scientists as an extremely good conductor of electrons due to its strength and its light weight.
Electric current flows without any resistance in a superconducting state thanks to a surprising redistribution of bonding electrons and the associated electronic and atomic behavior after substitution of some cobalt atoms for iron in barium iron arsenide.
