Effect of shock-heated flow on morphological and structural properties of anatase TiO2 nanoparticles

Shock Wave Induced Crystallographic Structural Phase Transitions (Tri-states) of l-Threonine Crystal

“…Of late, investigations of materials under shock wave impact have set off a potential platform that has materialized to generate a new wave of upsurge in today’s advancement such that new benchmarks could be set in identifying materials of sustainable properties. , On the same footing, understanding the phase transition of crystalline and noncrystalline materials under the influence of deforming forces is very much essential for identifying new materials that are of great demand for specific applications. − According to the classical thermodynamic theories, when materials undergo high temperature and high pressure, the process of phase transition may occur such that the phase transition may fall under any one of the categories of structural, chemical, electronic, and magnetic phase transitions. − On the other hand, the crystal structures may also switch to the amorphous nature. , For industrial applications, crystalline materials are highly required as compared to amorphous materials because crystalline materials possess superior and predictable physical as well as chemical properties which are essential for the design of the cutting edge technologies. − If a material undergoes phase transformation from one phase to another, it is observed that the structural, thermal, electrical, and optical properties are significantly changed . Hence, understanding the phase transition of materials under high pressure as well as high temperature is very much essential for a variety of applications.…”

Comparative Assessment of Crystallographic Phase Stability of Anatase and Rutile TiO2 at Dynamic Shock Wave Loaded Conditions

“…According to the literature, TiO 2 crystallizes in several crystallographic phases such as anatase (I4 1 /amd), rutile (P4 2 /mnm), brookite (Pbca), TiO 2 -B (C 2 /m), TiO 2 -R (Pbnm), TiO 2 -H (14/m), pyrite (Pa-3), columbite (Pbcn) and baddelyite (P2 1 /c), cotunnite, α-PbO 2 type TiO 2 , uorite (Fm3-m), cubic and post contunnite phases [24][25][26]. Based on the analysis on the above listed crystal structures, the primary phases of anatase, rutile and brookite phases of TiO 2 NPs are being widely used in industrial applications [27].…”
