Think of a data diode as the digital equivalent of a mechanical check valve—it forces network traffic to flow in one ...

Engineers have long known how to steer electricity in one direction, but heat has been far harder to tame. Now a new one-way thermal “diode” promises to give designers similar control over heat flow, ...

A TU Delft team has demonstrated a one-way superconductor that gives zero resistance in one direction, but blocks current completely in the other. The discovery, long thought impossible, heralds a ...
