Giant coercivity and spin clusters in high pressure polymorphs of Mn₂LiReO₆.

High-pressure polymorphs of anatase TiO2

Theoretical compressibilities of high-pressure ZnTe polymorphs

We report the results of a theoretical study of structural, electronic, and pressure-induced phase transition properties in ZnTe. Total energies of several high-pressure polymorphs are calculated using the density functional theory ~DFT! formalism under the nonlocal approximation. Thermal effects are included by means of a nonempirical Debye-like model. In agreement with optical absorption data...

the relationship between academic self-concept and academic achievement in english and general subjects of the students of high school

according to research, academic self-concept and academic achievement are mutually interdependent. in the present study, the aim was to determine the relationship between the academic self-concept and the academic achievement of students in english as a foreign language and general subjects. the participants were 320 students studying in 4th grade of high school in three cities of noor, nowshah...

consequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir

there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...

Structural morphologies of high-pressure polymorphs of strontium hydrides.

It is now known that the structure and properties of a material can be significantly altered under extreme compression. In this work, a structural search was performed to investigate the phase stabilities and structures of SrH2n (n = 1-5) in the pressure range of 50-300 GPa. The high-pressure polymorphs reveal a variety of hydrogen structural units ranging from monatomic hydride to linear and b...
