Du sperme de saumon pour doper les diodes LED

Source : University of Cincinnati

"Si l'on mange volontiers les oeufs de saumon, le sperme des mâles est considéré comme un déchet, ou plutôt l'était.
En effet, un chercheur lui a trouvé un débouché inattendu, fabriquer des diodes LED biodégradables qui utiliseront son ADN comme couche isolante chargée de retenir les électrons et d'obtenir une lumière très vive tout en consommant moins d'énergie.
Il reste à connaître la durée de vie de ces LED, et le coût de leur industrialisation. Pour peu qu'ils soient acceptables et l'industrie de plus en plus gourmande de ces diodes se ruera dessus."

C'est plus un poisson d'AVRIL, c'est un cachalot d'AOUT, tellement c'est gros. huh.gif

Cela dit tout comme l'evoque la fameuse question sans reponse "Que cherchait exactement à faire l'homme quand il a decouvert que la vache donnait du lait" je me demande bien ce que cherchait a faire le gars qui a decouvert ça...

Et que cherchait exactement la vache quand elle a découvert que l'homme donne des coups ???? biggrin.gif

Salmon Garnish Points the Way to Green Electronics

A University of Cincinnati (UC) researcher has an unusual approach to developing “green” electronics — salmon sperm.

Date: 9/10/2007

Phone: (513) 556-1826
Professor Andrew Steckl, a leading expert in light-emitting diodes, is intensifying the properties of LEDs by introducing biological materials, specifically salmon DNA.

Electrons move constantly — think of tiny particles with a negative charge and attention deficit disorder. It is through the movement of these electrons that electric current flows and light is created.

Steckl is an Ohio Eminent Scholar in UC’s Department of Electrical and Computer Engineering. He believed that if the electrons’ mobility could be manipulated, then new properties could be revealed.
In considering materials to introduce to affect the movement of the electrons, Steckl evaluated the source of materials with an eye to supply, especially materials that do not harm the environment.

“Biological materials have many technologically important qualities — electronic, optical, structural, magnetic,” says Steckl. “But certain materials are hard for us to duplicate, such as DNA and proteins.” He also wanted a source that was widely available, would not have to be mined, and was not subject to any organization or country’s monopoly. His answer?

Salmon sperm.

“Salmon sperm is considered a waste product of the fishing industry. It’s thrown away by the ton,” says Steckl with a smile. “It’s natural, renewable and perfectly biodegradable.” While Steckl is currently using DNA from salmon, he thinks that other animal or plant sources might be equally useful. And he points out that for the United States, the green device approach takes advantage of something in which we continue to be a world leader — agriculture.
