Pressure is a fundamental thermodynamic variable that can be used to control the properties
of materials, because it reduces interatomic distances and profoundly modifies electronic …

Hardness can be defined microscopically as the combined resistance of chemical bonds in
a material to indentation. The current review presents three most popular microscopic …

In recent days, study of topological Weyl semimetals have become an active branch of
physics and materials science because they led to realization of the Weyl fermions and …

Although diamond is the hardest material for cutting tools, poor thermal stability has limited
its applications, especially at high temperatures. Simultaneous improvement of the hardness …

Hardness and fracture toughness are some of the most important mechanical properties.
Here, we propose a simple model that uses only the elastic properties to calculate the …

Though extensively studied, hardness, defined as the resistance of a material to
deformation, still remains a challenging issue for a formal theoretical description due to its …

Cubic boron nitride (cBN) is a well known superhard material that has a wide range of
industrial applications. Nanostructuring of cBN is an effective way to improve its hardness by …

In general, inorganic non‐metallic materials exhibit brittleness, and achieving plasticity in
wide‐gap semiconductors or dielectrics poses an even greater challenge. Historically, silver …

A structurally stable crystalline carbon allotrope is predicted by means of the first-principles
calculations. This allotrope can be derived by substituting each atom in diamond with a …

Fracture toughness KIC plays an important role in materials design. Along with numerous
experimental methods to measure the fracture toughness of materials, its understanding and …
