Small-Angle Neutron Scattering Reveals how High Explosives Age Ungracefully
Neutron scattering is a non-invasive technique which can be used on very small sample sizes - allowing analysis of explosives without having to detonate them.
Researchers have found that polymer explosives age due to a process called crosslinking, which decreases material strength.
Study of this problem can aid in national defense applications, where an understanding of the aging explosives is essential.
