German scientists claim to have produced a long-sought material
By: Devin Powell
For 76 years scientists have been trying to create a material that would be a prefect conductor for wires in spaceships because of its low electricity loss, this material is called metallic hydrogen. Two German scientists claim to have created this metallic hydrogen by squeezing a room temperature sample of hydrogen between two diamonds at a stunning 2.3 millions times the pressure of earths atmosphere to create an opaque and reflective metal. Other scientists are skeptical though because scientists before have thought to have created this material. In 1996 William Nellis and a few of his colleagues used shock waves to create hydrogen that conducted electricity though it only lasted a fraction of a second. Erments plans to silence critics be recreating the experiment and recreating this metal. “Hydrogen attracts so much attention in our field,” says Eremets. “Of course there will be a lot of emotion, of course there will be a lot of demands.”
I chose this article because I thought it would relate well to what we were doing in class since we were learning about elements and chemical reactions/changes. I also thought that the method they used to achieve this change was very interesting since they pretty much crushed the hydrogen between two diamonds. I thought this was a very cool article and I think that if they actually did make this that it could be a great innovation for mankind.

When I think of Hydrogen, I do not think of a metal, but a gas. It's interesting isn't it that they can crush hydrogen between two diamonds, that much have been in a very cold place for it to be a solid.
