(Phys.org) —Metallic glasses are essentially a frozen, supercooled liquid. They are amorphous metals, often alloys, which are non-crystalline and therefore have a highly disordered atomic arrangement. They are true glasses ...
The importance of silicon for almost every element in modern-day electronic devices and computers is due largely to its crystalline atomic structure. Crystalline silicon, however, is much more expensive to produce than its ...

At their core, electron microscopes work a lot like a movie projectors. A high-powered beam passes through a material and it projects something—usually something we really want to see—onto a screen on the other side. ...
