Various experimental techniques show that atoms adsorbed onto a crystal surface form two‐dimensional arrays with a structure that depends on their density, the temperature and the substrate.
If we wish to understand the properties of a solid surface, we must begin with some picture of the geometrical arrangement of atoms in the outermost layers of the solid. Such a structural model represents an essential ingredient in any microscopic description of a material.

Amid growing investment in planetary-scale climate intervention strategies that alter sunlight reflection, global communities deserve inclusive and accountable oversight of research.
Although motivated by the fundamental exploration of the weirdness of the quantum world, the prizewinning experiments have led to a promising branch of quantum computing technology.
As conventional lithium-ion battery technology approaches its theoretical limits, researchers are studying alternative architectures with solid electrolytes.
