This image of Jezero Crater on Mars shows a layer of mineral data measured from orbit. The green color represents carbonates – minerals that form in aqueous environments under conditions that may be favorable for preserving signs of ancient life. NASA's Perseverance rover is currently studying the green area above the Jezero alluvial fan (center). Credit: NASA/JPL-Caltech/MSSS/JHU-APL

In the picture: an illustration of the arrangement of water molecules at temperatures around the freezing point, arranged around a single reference molecule. The white area shows the orderly and directional organization of the water density in the form of an "oyster", which results from the properties of the bonds between the hydrogen molecules. The orange color shows a "volume increase area", which a water molecule cannot penetrate, due to its structural characteristics. Source: IBM.

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.

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.
