The cosmic optical background (COB) is the visible light emitted by all sources outside of the Milky Way. This faint glow of light, which can only be observed using very precise and sophisticated telescopes, could help astrophysics ...
Gamma rays can cause serious damage to the human body. Therefore, it is very important to develop gamma-ray shielding materials with excellent radiation shielding properties. To reach this goal, scientists in China invented ...
