Noble Gases

Noble Gases

The elements in group 18 are noble gases (helium, neon, argon, krypton, xenon, and radon). They earned the name “noble” because they were assumed to be nonreactive since they have filled valence shells. In 1962, Dr. Neil Bartlett at the University of British Columbia proved this assumption to be false.

$X-ray Diffraction of Biological Samples$ 01:10

X-ray Diffraction of Biological Samples

X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, polycrystalline materials, proteins, carbohydrates, and drugs.
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal...

X-ray Crystallography

X-ray Crystallography

The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

Crystal Growth: Principles of Crystallization

Crystal Growth: Principles of Crystallization

Crystallization is a phase transformation process in which crystals are precipitated from a supersaturated solution or formed from other sources. During crystallization, atoms or molecules arrange themselves into a well-defined, rigid crystal lattice to minimize energy.
Initiating crystallization involves manipulating the concentration of the solute and the temperature of the solution. Since crystal growth occurs when the ratio of concentration and solubility of the solute in the solvent...

Background:

Xenon (Xe) and krypton (Kr) gas separation is crucial but difficult due to similar molecular properties.
Hydrate-based gas separation offers a promising method for separating these noble gases.

Purpose of the Study:

To investigate the efficacy of hydrate-based gas separation for xenon/krypton mixtures.
To analyze the influence of temperature and pressure on guest molecule occupancy within hydrate cages using molecular dynamics simulations.

Main Methods:

Utilized molecular dynamics (MD) simulations to model hydrate formation and guest molecule encapsulation.
Examined the occupancy of xenon and krypton in different hydrate cage structures (5¹², 5¹²6⁴) under varying temperature and pressure conditions.

Main Results:

Increased temperature and pressure enhanced xenon occupancy in both 5¹² and 5¹²6⁴ cages.
Elevated pressure improved krypton occupancy in 5¹²6⁴ cages, with minimal impact on 5¹² cage occupancy.
Higher temperatures and pressures reduced the number of empty hydrate cages, indicating more efficient guest molecule filling.

Conclusions:

Hydrate-based separation is a viable strategy for xenon/krypton mixtures.
Xenon preferentially occupies larger 5¹²6⁴ cages, while krypton favors smaller 5¹² cages.
Optimizing temperature and pressure conditions can enhance separation efficiency by influencing guest molecule distribution within hydrate cages.
