The process by which a crystal nucleates and grows within a glass during heat treatments remains a conceptually ill-understood phenomenon. Researchers in Brazil developed a nuclear magnetic resonance strategy combined with atomistic computer simulations that allowed them to shed unprecedented light on the structural changes that take place in a glass during relaxation and crystal nucleation.

Researchers are taking advantage of a nitrogen vacancy in flawed diamonds to view how atoms spin and connect to form molecules. Their discovery could eventually lead to smaller MRI machines that are less invasive and use considerably less energy.
