Equations of circuit theory led to a prediction of the memristor almost 40 years before the device was discovered. The equations state relations among four variables: charge (q), current (i), voltage ...

Three-dimensional steady-state heat transfer simulation. (a) Temperature map for an x–y slice taken through the middle of a 2 nm high and 100 nm wide cylindrical uniform heat source located directly ...

After nearly 40 years, researchers have discovered a new type of building block for electronic circuits. And there's at least a chance it will spare you from recharging your phone every other day.
