U.S. Naval Research Laboratory The Department of Defense needs materials for armor windows that provide essential protection for both personnel and equipment while still having a high degree of transparency. To meet that need, scientists at the U.S. Naval Research Laboratory (NRL) have developed a method to fabricate nanocrystalline spinel that is 50% harder than the current spinel armor materials used in military vehicles. With the highest reported hardness for spinel, NRL's...

Chicago -- Scientists at the American Museum of Natural History and the University of Chicago have explained how a globe-encircling residue formed in the aftermath of the asteroid impact that triggered the extinction of the dinosaurs. The study, which will be published in the April issue of the journal Geology, draws the most detailed picture yet of the complicated chemistry of the fireball produced in the impact. The residue consists of sand-sized droplets of hot liquid that condensed from...
