In SHeM, a fine beam of low-energy helium atoms is scanned across the sample surface.

Selective leaching is a process commonly used in metallurgy and mineral processing to extract specific metals or minerals from ores or concentrates. In this technique, certain components of a solid material are dissolved and removed while leaving others relatively intact. This selective dissolution is achieved by using suitable solvents or chemical agents that preferentially interact with the target material. The main features of selective leaching include: 1. **Targeted Dissolution**: The process aims to extract a specific metal (e.g.

The cation-anion radius ratio is a concept used in chemistry and materials science to understand the stability and coordination of ions in solid ionic compounds. It is defined as the ratio of the radius of a cation (positively charged ion) to the radius of an anion (negatively charged ion). This ratio plays a critical role in predicting the arrangement of ions in a crystal lattice and the type of structure that will form.

Fractional coordinates are a way of expressing the positions of points in a crystal lattice or within a unit cell of a crystal structure. Instead of using absolute coordinates (like Cartesian coordinates in a specific unit of measurement), fractional coordinates are given as a fraction of the unit cell parameters. In a crystal lattice, the unit cell is the smallest repeating unit that defines the entire structure of the crystal.

The Laue equations describe the relationship between the wave vectors of incident and scattered waves in the context of X-ray diffraction, particularly in crystallography. They are crucial for understanding how X-rays interact with crystal lattices and help in determining the structure of crystalline materials. When X-rays are directed at a crystal, they can be diffracted by the periodic lattice of atoms within the crystal. The Laue equations apply to the diffraction of X-rays when they enter a crystal at specific angles.
