Speaker: Prof. Anthony Stace FRS

Clusters consisting of finite numbers (10-10000) of atoms and molecules are studied in the gas phase in order to understand the connection between the properties of a single species, for example an atom, and how that same substance behaves as a bulk material. Examples of the types of questions we might want to answer are: how many copper atoms does it take to make a piece of copper wire or how many water molecules do you need to dissolve common salt (sodium chloride)?  Modern experiments are capable of giving answers to these and many more questions on how the physical properties of substances evolve as a function their size.
