Each crystal structure minimizes the energy of the system. The energy of the sodium ions is not entirely due to attractive forces between oppositely charged ions.
WebAbstract. A new crystal form of rabbit muscle aldolase shows that the molecule has 222 symmetry to at least 4-angstrom resolution, and hence that the gross conformation of the four subunits is the same. Comparison of the new form with a previously reported form establishes the number of molecules per unit cell, n, in the older form. WebWe studied the equilibrium self-assembly of an equimolar mixture of uniaxial liquid crystals (LCs) and magnetic nanoparticles (MNPs) using molecular dynamics simulations. The LCs are modeled by ellipsoids interacting via Gay–Berne potential, and MNPs are represented by dipolar soft spheres (DSS). We found that the LCs show isotropic, nematic, and …
WebIron has two different crystal structures at atmospheric pressure: the body centered cubic (bcc) and the face centered cubic (fcc). In the ground state the bcc α-phase is stable, and at the temperature T=1184 K (A 3 point), α-Fe transforms into fcc α-Fe, which is stable up to 1665 K (A 4 point).
