In the study, the scientists examined collisions that occur between the molecules. Collisions of atoms have been studied in the past, but atoms - according to classical physics - are spherical, while molecules have an elongated structure. The structure of a colliding body affects the way it will move after the collision. Will elongated molecules behave differently from spherical atoms? And is knowing their shape enough to predict the outcome of the collision? Illustration: pixabay.com.

Computer simulation of the atomistic model of the particle. It can be seen that the material moved by the diamond needle accumulates at the edge of the particle and creates unique steps, which are later used as "guide rails" that return to the footprint, by diffusion, the material moved to the side. After a time the particle returns to its original shape. Source: Courtesy of the Technion.

Detection of chemical activity on the surface of nanometer-sized platinum particles, which are used as catalysts in the chemical industry, was made possible by focusing infrared light onto a nanometer-sized needle. These measurements showed for the first time how and where chemical activity occurs on the surface of the particles
