An orbital structure is the space in an atom that’s occupied by an electron. But when describing these super-microscopic properties of matter, scientists have had to rely on wave functions — a ...

The high power electron microscopes are used primarily for probing atomic structure of strong, solid materials, such as graphene -- a lattice of carbon only one atom thick.

An image of the graphene structure can be created with these electrons." Researchers have been aware of the principle of "energy-filtered transmission electron microscopy" (EFTEM) for some time.

Figure 1d shows three characteristic carbon K-edge fine structures extracted using sequential electron energy-loss spectroscopy (EELS) with probe-scanning (known as the spectrum-image mode) 11.

Two laboratories recently used cryo-electron microscopy to directly image atoms in a protein molecule with a resolution of about 1.2 x 10-7 millimeters or 1.2 ångströms. The previous record was ...

Chemistry textbooks typically include illustrations of atoms, but with caveats. The drawings depict atomic nuclei surrounded by electron orbitals—fuzzy spheres, barbells, tripods, and so on ...

Electron ptychography reveals sub-angstrom features in 2D molybdenum disulphide (Nature 559 343–349) A new electron microscopy technique that achieves far better resolution than ever before, while ...

After measuring pair-wise couplings within the cluster at high accuracy and high resolution, the team used algorithms to build up 3D images of the structure to a precision of better than 0.1 nm. This ...

As electron microscopy technologies have improved and scientists have a greater knowledge of how to manipulate specific atom types, the complexity of the measurements, imaging and manipulation with ...

For example, an electron energy of 100 keV is needed to transfer approximately 20 eV to a carbon atom; this is the threshold for displacing the atom permanently in a graphitic structure.

Scientists have set up and observed a single electron bond between two carbon molecules. A traditional “single bond” is ...
