A density functional study of the high-pressure chemistry of MSiN(2)(M = Be, Mg, Ca): prediction of high-pressure phases and examination of pressure-induced decomposition.
Modification normal pressure and high pressure phase of nitridosilicates tentative new engine (2) with M = Be, Mg, Ca or have been thoroughly studied by the density functional method. At ambient pressure, besin (2) and MgSiN (2) shows an ordered hexagonal variant derived from β-cristobalite ideal filled by C1-type distortion.
At ambient pressure, Casin structure (2) can also be derived from β-cristobalite ideal filled by various types of distortion (D1-type). energy calculations reveal the volume for the third compound transition into the superstructure NaCl under pressure, affording sixfold coordination for Si. At 76 GPa besin (2) forming LiFeO (2) -type structure, according to the ambient-pressure stable modification LiFeO (2), while MgSiN (2) and Casin (2) adopt LiFeO (2) -type structure, in accordance with modifications metastable (24 and 60 GPa, respectively).
For both besin (2) and Casin (2) intermediate phases appear (for besin (2) chalcopyrite-type structure and for Casin (2) -type structure CaGeN (2)). Both medium-tetragonal structure closely related, differing mainly in their c / a ratio. As a result, the structure of chalcopyrite-type shows tetrahedral coordination for the second cation (M and Si), whereas in CaGeN (2) -type structure of the cation is tetrahedrally (Si) and one bisdisphenoidally (M) coordinated. Both types of structures, chalcopyrite and CaGeN (2), can also be derived from β-cristobalite ideal filled through the B1-type distortion.
Group-subgroup relations besin (2) / MgSiN (2), Casin (2), chalcopyrite, the CaGeN (2) and β-cristobalite structure ideal filling is discussed and illustrated displacive phase transformation path. Zero-pressure bulk modulus is calculated for all phases and have been found to be comparable with compounds such as α- Si (3) N (4), Cairo (3) and Al (4) C (3). In addition, the thermodynamic stability of gasoline (2), MgSiN (2) and Casin (2) of the nitride phase binary blob M (3) N (2) and Si (3) N (4) under pressure checked.

A first-principles analysis on phase stability, chemical bonding and the band gap of the hexagonal structure of A (x) Zn (1-x) O alloy (A = Ca, Cd, Mg).
The phase stability and structural properties and electronic three alloy systems of the zinc oxide-based (Ca (x) Zn (1-x) O, Cd (x) Zn (1-x) O and Mg (x) Zn (1-x) O) was studied by first-principles methods. We checked all the configuration of the alloy in three (structure 1 × 1 × 2 B1 phase, the structure of 2 × 2 × 1 and 2 × 1 × 2 stages B4) 16-atom supercells and take advantage of the symmetry of the bulk material to reduce the number of calculations.
Taking into account the contribution of the statistics alloys, we have drawn the phase stability region for Ca (x) Zn (1-x) O (0.25 <x <0.375), Mg (x) Zn (1-x) O (0.375 <x <0.5) and Cd (x) Zn (1-x) O (0.75 <x <0.875). We also have analyzed the lattice constants (a and c), the structural parameters u and the bond length in the hexagonal phase.

Description: This gene encodes an enzyme involved in catalyzing the conversion of angiotensin I into a physiologically active peptide angiotensin II. Angiotensin II is a potent vasopressor and aldosterone-stimulating peptide that controls blood pressure and fluid-electrolyte balance. This enzyme plays a key role in the renin-angiotensin system. Many studies have associated the presence or absence of a 287 bp Alu repeat element in this gene with the levels of circulating enzyme or cardiovascular pathophysiologies. Multiple alternatively spliced transcript variants encoding different isoforms have been identified, and two most abundant spliced variants encode the somatic form and the testicular form, respectively, that are equally active.
