Record-breaking, ultrafast devices step to protecting the grid from EMPs

Scientists have announced a tiny, electronic device that can shunt excess electricity within a few billionths of a second while operating at a record-breaking 6,400 volts -- a significant step towards protecting the nation's electric grid from an electromagnetic pulse.

Physicists show how frequencies can easily be multiplied without special circuitry

A new discovery by physicists could make certain components in computers and smartphones obsolete. The team has succeeded in directly converting frequencies to higher ranges in a common magnetic material without the need for additional components. Frequency multiplication is a fundamental process in modern electronics.

A 'zigzag' blueprint for topological electronics

A collaborative study confirms a potential new switching mechanism for a proposed generation of ultra-low energy topological electronics. Based on novel, quantum nanoribbons terminating on 'zigzag' edges, such devices would switch from non-conducting to conducting state, whereby electrical current could flow along topological edge states without wasted dissipation of energy.
