Oscillatory behavior of rare-gas atoms in SWCNT

Article Abstract:

The process of rare-gas atoms (He, Ne, Ar, Kr, Xe) injected into single-walled carbon nanotube (SWNT) and the mechanical oscillatory behavior of rare-gas atoms sliding in a SWCNT by using molecular dynamics simulations is investigated. It is found that the oscillatory frequencies are insensitive to the initial kinetic energy but they are sensitive to the lengths and the radius of the tube and they decrease as the length and the radius of the tube increases.

Defect-mediated melting in superheated noble gas crystals

Article Abstract:

Molecular dynamics simulations were used to investigate the mechanisms governing the homogeneous melting of pure noble gases at the limit of superheating. To determine the limit to superheating, calculations were carried out on a perfect crystalline bulk and their relative number and spatial correlation appeared to play a fundamental role in destabilizing the crystalline lattice bulk and triggering the homogenous melting.

Kr extended X-ray absorption fine structure study of endohedral Kr@C(sub 60)

Article Abstract:

An extended X-ray absorption fine structure (EXAFAS) investigation is conducted at the K-edge of Kr atoms in C(sub 60) cages. EXAFAS provides vital details about the structure as well as the dynamics of the system.
