Innover dans les services publics locaux de l’eau et des déchets

Innover dans les services publics locaux de l’eau et des déchets | ecodesign and chemical regulation | Scoop.it

Le Congrès 2014 de l’ASTEE s’est tenu à Orléans du 3 au 6 juin sur le thème « Innover dans les services publics locaux de l’environnement ». Les incitations et les freins à l’innovation sont aussi divers que les objets et modalités de cette innovation (technologies, procédés, méthodes, organisations, institutions…). Les processus en jeu relèvent à la fois de la création, de la méthode.

This Is Your Brain On Aspartame

This Is Your Brain On Aspartame | ecodesign and chemical regulation | Scoop.it

“ The FDA claims aspartame is safe. Researchers claim it causes memory loss, mood changes, and depression. Who are you going to believe?” Controversy continues to rage over the artificial sweetener aspartame. Since it was first approved by the Food and Drug Administration (FDA) in 1981, aspartame has made its way into more than 6,000 food items. The FDA claims aspartame is safe but has set an acceptable daily intake of no more than 50 mg per kilogram of body weight. In other words, an adult weighing 165 pounds should consume no more than 3,750 mg of aspartame a day. A can of diet soda typically contains about 180 mg of the chemical. That means the FDA's "safe" limit equates to about 21 cans of diet soda per day. But is any level of aspartame really safe?

Researchers may have solved graphene’s production problems, cleared way for mass production

Researchers may have solved graphene’s production problems, cleared way for mass production | ecodesign and chemical regulation | Scoop.it
A new method of producing graphene could be the major breakthrough scientists are looking for. If the new method of producing the material on a thin polymer works at commercial scale, it could clear the way for mass production.

 

The potential for reproducing and adopting these graphene-like carbon nanosheets for other markets is what makes this story interesting. The team didn’t say what percent of the graphene was defect-free, but they do claim that this new manufacturing method is far simpler and less prone to failure than previous types of graphene production.


If this technique can be adapted to semiconductors or other types of solar cells, it could be far more useful than any marginal gain in organic solar cell efficiency.


According to Dr. Han Ik Joh at the Korean Institute for Science and Technology, graphene can be produced in a similar manner to carbon fiber — and while that’s hardly cheap, it’s still better than our current methods.

NASA’s tiny 460GHz vacuum transistor that could one day replace silicon FETs | Nano Technology

NASA’s tiny 460GHz vacuum transistor that could one day replace silicon FETs | Nano Technology | ecodesign and chemical regulation | Scoop.it
Way back in the salad days of digital computing (the 1940s and '50s), computers were made of vacuum tubes -- big, hot, clunky devices that, when you got right down to it, were essentially glorified light bulbs. This is why early computers like the ENIAC weighed more than 27 tons and consumed more power than a small town. Later, obviously, vacuum tubes would be replaced by probably the greatest invention of all time -- the solid-state transistor -- which would allow for the creation of smaller, faster, cheaper, and more reliable computers. Fast forward to 2014, though, and the humble CMOS field-effect transistor (FET) is starting to show its age. We've pretty much hit the limit on shrinking silicon transistors any further, and they can't operate at speeds much faster than a few gigahertz. Which is why NASA's Ames Research Center is going back to the future with its new vacuum transistor -- a nanometer-scale vacuum tube that, in early testing, has reached speeds of up to 460GHz.
