Un modello del catalizzatore a base di zeolite: le sfere nere rappresentano gli atomi di silicio o di alluminio (c'è un atomo di alluminio per ogni 9 atomi di silicio circa), mentre i pezzi di collegamento trasparenti contengono ciascuno un atomo di ossigeno come ponte

Insieme, i tre formano una struttura complessa ma regolare con pori di diverse dimensioni. © Istituto Paul Scherrer PSI/Mahir Dzambegovic

Barely larger than a fingernail, the miniature Roman box lock from the 3rd or 4th century AD
Barely larger than a fingernail, the miniature Roman box lock from the 3rd or 4th century AD is skilfully crafted out of gold. The iron mechanism inside remained hidden for a long time because conventional imaging techniques were thwarted by the dense gold casing. It was only with the help of neutron tomography at PSI that the box lock could finally be deciphered non-destructively. © LWL/S. Brentführer
