We obtain a comprehensive image of the germania film structure by combining intensity-voltage low-energy electron diffraction (I/V-LEED) and ab initio density functional theory (DFT) analysis with atomic-resolution scanning tunneling microscopy (STM) imaging. For benchmarking purposes, the bare Ru(...

The paper includes the first quantum mechanical calculation of a dissimilar metal interface with a view to obtaining the structure of a misfit dislocation and a value for the theoretical strength of the interface. It is concluded that the misfit dislocation in this case has a widely spread core ...

Knowing how crystals nucleate at the atomic scale is crucial for understanding, and in turn controlling, the structure and properties of a wide variety of materials. However, because of the scale and highly dynamic nature of nuclei, the formation and early growth of nuclei are very difficult to...

Atomic Structure refers to the fundamental components of matter, namely atoms, which consist of a nucleus and orbiting electrons. The nucleus, acting as the center of an atom, is positively charged and has a much greater mass than the negatively charged electrons. Atoms are electrically neutral ...
Democritus model of atom ~ 400 BCFig. 1. The Democritus concept of atom. If you keep cutting a metal eventually a point is reached where cutting the metal any further would not be possible. The smallest unit of metal is known as atom. The concept of atom evolved from the understanding ...
The structure of the molecule's gold core was previously detailed by the Stanford team. Building on this, Zeng and his colleagues used a computational framework dubbed "divide-and-protect" to configure potential arrangements of the remaining gold atoms and sulfur-hydrogen pairs surrounding the core...
