3D printing promises more efficient ways to make custom explosives and rocket propellants

‘Energetic’ materials are ones that readily ignite or detonate. The shapes of those materials have a big effect on how they burn or blow up.

Combining two types of molecular boron nitride could create a hybrid material used in faster, more powerful electronics

Two forms of the same boron nitride molecules couldn’t look and act more different – but combining them could lead to applications that have the best of both worlds.

Space rocks and asteroid dust are pricey, but these aren't the most expensive materials used in science

Some space rocks you can get for free – if you know how to identify them. Rarer materials cost more, and the asteroid sample NASA just brought back has a high price tag.

Room-temperature superconductors could revolutionize electronics – an electrical engineer explains the materials' potential

Superconductors make highly efficient electronics, but the ultralow temperatures and ultrahigh pressures make them costly and difficult to use. Room-temperature superconductors promise to change that.
