Discover how to create a simple solar energy harvester at home using basic household items and electronic components. This ...

The Arduino UNO R4 brought a modern 32-bit platform to the UNO form factor. Arduino’s Alessandro Ranellucci explained the features to Stuart Cording.

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 ...

A new mechanism steers diodes made of a single enantiomer to emit light of right- and left-handed polarizations ...

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 ...

Inorganic LEDs are light-emitting diodes (LEDs) made from a crystalline semiconductor. The optical emission wavelength can be selected by varying material composition. Example active regions include ...
