Unusual electron sharing found in cool crystal Date: July 31, 2020 Source: Nagoya University Summary: Tungsten atoms are seen to come together in a way that is similar to an outer space ion.

The latest models of tabletop SEMs (TT-SEMs) feature a range of electron sources. Although a tungsten filament is used in a majority of TT-SEMs, certain models come with a Cerium Hexaboride (CeB 6) ...

Nucleophilic Attack: A fundamental reaction mechanism where an electron-rich species targets an electron-deficient centre to form a new chemical bond. Acetylene Hydratase and Tungsten Complexes ...

The shortest electron pulses ever made in the lab have been claimed by researchers in Germany. By firing ultrashort laser pulses at a tungsten nanotip, the team created electron pulses just 53 ...

A new technology has been developed to fabricate lanthanum hexaboride (LaB6) single-crystal nanowires with clean surface, a promising cold field-emission electron source for electron microscopes ...

Tungsten has the highest melting point of all metals, 3,422 degrees Celsius. This makes the material ideal for use at high temperatures in e.g. space rocket nozzles, heating elements of high ...

Proceedings of the American Academy of Arts and Sciences Vol. 60, No. 6, Oct., 1925 Certain Physical Properties of Single Crystals of Tungsten, Antimony, Bismuth, Tellurium, Cadmium, Zinc, and Tin ...
