Transformation pathways of silica under high pressure.
Network-forming oxides with rigid polyhedral building blocks often possess significant capacity for densification under pressure owing to their open structures. The high-pressure behaviour of these oxides is key to the mechanical properties of engineering materials and geological processes in the Earth's interior. Concurrent molecular-dynamics simulations and first-principles calculations revea...
متن کاملBoron under Pressure: Phase Diagram and Novel High-pressure Phase
Boron has a unique chemistry, responsible for remarkable complexities even in the pure element. I review some of the history of the discovery of this element, and recent surprises found in boron under pressure. I discuss the recent discovery of a new high-pressure phase, γ-B28, consisting of icosahedral B12 clusters and B2 pairs in a NaCl-type arrangement: (B2)(B12), and displaying a significan...
متن کاملPhase transition induced strain in ZnO under high pressure
Under high pressure, the phase transition mechanism and mechanical property of material are supposed to be largely associated with the transformation induced elastic strain. However, the experimental evidences for such strain are scanty. The elastic and plastic properties of ZnO, a leading material for applications in chemical sensor, catalyst, and optical thin coatings, were determined using i...
متن کاملPhase Transition in Mixed Transition Metal Oxides under High Pressure
Mixed crystals can be categorized as the crystal in which two or more different types of atoms are present and configured. These atoms interact each other in the influence of Coulomb force of attraction and the presence of short range repulsion force. Due to this interaction they tends to be arranged in equilibrium state and forms new material. A pure crystal can be doped by impurities with pro...
متن کاملMolecular to atomic phase transition in hydrogen under high pressure.
The metallization of high-pressure hydrogen, together with the associated molecular to atomic transition, is one of the most important problems in the field of high-pressure physics. It is also currently a matter of intense debate due to the existence of conflicting experimental reports on the observation of metallic hydrogen on a diamond-anvil cell. Theoretical calculations have typically reli...
