Your car only starts reliably because two electrical workhorses share the load. The battery delivers instant power on demand, while the alternator keeps that energy flowing once the engine runs.

A diode is a tiny component that controls the flow of electricity by allowing current to pass in only one direction. This video explains how diodes work, what makes them unique, and why they’re used ...

A process developed at ETH Zurich enables the massive miniaturisation of organic light-emitting diodes (OLEDs) in only one single step. The light sources are now smaller than the wavelength of the ...

Organic LEDs are light emitting diodes (LEDs) that use polymers or small organic molecules as their optically active element. Development of organic LEDs is driven in particular by its potential as a ...
