Network Covalent Solids

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Nuclear Transmutation

Nuclear Transmutation

Nuclear transmutation is the conversion of one nuclide into another. It can occur by the radioactive decay of a nucleus, or the reaction of a nucleus with another particle. The first manmade nucleus was produced in Ernest Rutherford’s laboratory in 1919 by a transmutation reaction, the bombardment of one type of nuclei with other nuclei or with neutrons. Rutherford bombarded nitrogen-14 atoms with high-speed α particles from a natural radioactive isotope of radium and observed protons being...

Summary

Helium atoms move through carbon nanotubes due to van der Waals forces. Transportation efficiency depends on loading conditions, rate, and temperature, driven by nanotube kink propagation.

Area of Science:

Nanotechnology
Materials Science
Computational Physics

Background:

Single-walled carbon nanotubes (SWCNTs) offer unique properties for nanoscale transport.
Understanding atomic interactions within nanotubes is crucial for developing novel devices.

Purpose of the Study:

To investigate the mechanism and efficiency of helium atom transportation within SWCNTs.
To identify key factors influencing helium transport dynamics.

Main Methods:

Molecular dynamics simulations were employed to model helium atom behavior.
Analysis focused on the influence of loading type, loading rate, and temperature.

Main Results:

Helium atom transportation is governed by van der Waals forces between helium and the SWCNT.
