(Nanowerk News) Freestanding clusters of twenty gold atoms take the shape of a pyramid, researchers discovered. This is in contrast with most elements, which organize themselves by forming shells ...

Pyramidal neurons have basal and apical dendrites, including an apical tuft. This preserved core structure suggests that they have conserved core functions, whereas structural variation in other areas ...

Clusters composed of a few atoms tend to be spherical. They are usually organized in shells of atoms around a central atom. This is the case for many elements, but not for gold! Experiments and ...
