In order to get rid of unpleasant competitors, some bacteria use a sophisticated weapon - a nanosized speargun. Researchers have now gained new insights into the construction, mode of action and recycling of this weapon.
Scientists have developed a fully scalable method for the synthesis of atom-precise platinum clusters for potential use in catalytic applications. This method could provide a new pathway for large-scale production of atom-precise clusters.
Atoms emit electrons when a material is irradiated with light at a sufficiently high frequency. Previously, physics had assumed that the motion of these photoelectrons is determined by the properties of the material. In a new study, physicists show that it is the interplay of the electrons within the atom that is decisive.
