The diagram shows a simple model of metallic structure. The metal ions are shown as tiny spheres, packed closely together in a regular pattern.

Using JSC's JUQUEEN supercomputer, University of Cologne researchers were able to simulate the structure of silicon dioxide at a variety of different pressures. The image shows how the the shape ...

1 The electronic structure of sodium can also be shown in a diagram. Each dot represents an electron. Since the atomic number of oxygen is 8, it will have 8 protons in the nucleus. An atom of ...

Photo: Niels Bohr's research notes for his new atomic theory Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is ...

If the substrate has been prepared with an ultrathin layer of silicon dioxide on top ... owing to its unique electronic structure, the effective mass of the conduction electron vanishes.

Why is knowing the atomic structure of molecules useful? Learn why, and how information like this about protein structure is shared through a publicly available database. Scientists use a variety ...

Heavy water is a form of water with a unique atomic structure and properties coveted for the production of nuclear power and weapons. Like ordinary water—H 2 0—each molecule of heavy water ...

FOR THE discerning timekeeper, only an atomic clock will do ... such as the fine-structure constant, which determines the strength of the electromagnetic force. These seem to have fixed values ...

Animation showing the atomic structure of a new material sporting wavy layers of atoms. Credit: Paul Neves, MIT "We essentially mix powders of material, expose them to temperatures of a few ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

Such a device would greatly surpass the capabilities of atomic clocks, which define the span of a second through controlled energy jumps in atoms’ electrons and are currently the pinnacle of ...
