The spirit of Alfred Nobel has prevailed this year as the committee of the Swedish Royal Academy awards the Nobel Prize for Physics to three scientists whose investigations will be of great benefit to mankind: they have invented “efficient blue light-emitting diodes which have enabled
October 2013 saw the 50th anniversary of the invention of the LED (light-emitting diode), attributed to the General Electric engineer Nick Holonyak. However, in order to tell the complete story of this lighting system, which now forms an integral part of our daily lives, it seems we a
The Russian-born scientists Andre Geim and Konstantin Novoselov were working at Manchester University (United Kingdom) when they received the news that they had won the Nobel Prize for Physics for their research on graphene. Six years earlier, in 2004, they had discovered the material
Thanks to Rudolf Diesel’s invention we are able to produce Inmesol generators: the diesel internal combustion engine generates the mechanical energy necessary for the alternator (another essential component) to produce the electric power supplied by the generator.
Thanks to Tesla, our homes and any other building have electricity at the flick of a switch. He invented the AC induction motor, the Tesla coil for the alternating-current generator, spark plugs, the alternator, radio, remote control, fluorescent and neon light among the more than sev
Alessandro Volta invented what is known as the Volta pile, the forerunner of the electric battery. His work constitutes a crucial milestone in the history of science since he was the first inventor who managed to produce a stable flow of electricity. His battery was made out of altern
