Gamma Spectroscopy for Asteroid Mining

Asteroids are constantly awash in a bath of cosmic rays which produce neutron showers when they collide with atoms in the material of the asteroids. The neutrons in turn collide with other particles, giving off gamma rays in the process. Spectrum analysis of the gamma radiation can determine which elements were involved in the collisions […]

Ultra Light Absorber

Researchers at the Huygens Laboratory in Leiden University in the Netherlands have demonstrated that at a very thin level of thickness, NbN (niobiumnitride) can absorb nearly 100% of light. The ideal substance for photovoltaic solar energy conversion is something that absorbs almost all radiation and is thin enough to collect electrical energy efficiently. Most recent […]
