Researchers have made some of the first movies of the structural changes in tiny catalyst particles that may someday help them more efficiently build miniature electronic circuits and other nanotech devices.
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.
