Boundary energy: defined

For the phase stability analysis we follow the method given by Kanamori and Kakehashi of geometrical inequalities and compute the antiphase boundary energy defined by... [Pg.28]

The chemical reaction corresponds to a preparation-registration type of process. With the volume periodic boundary conditions for the momentum eigenfunction, the set of stationary wavefiinctions form a Hilbert space for a system of n-electrons and m-nuclei. All states can be said to exist in the sense that, given the appropriate energy E, if they can be populated, they will be. Observe that the spectra contains all states of the supermolecule besides the colliding subsets. The initial conditions define the reactants, e.g. 1R(P) >. The problem boils down to solving eq.(19) under the boundary conditions defining the characteristics of the experiment. [Pg.35]

It is standard practice in thermodynamics to divide things up into the system and the surroundings (Frame 1). Figure 7.1 shows two examples. In defining the system we define a definitive boundary. Once this designation is made, thermodynamics then considers the transfer of energy (defined as the capacity to do work, w or transfer heat, q) and matter to and from the system. For this we need to adopt a sign convention. [Pg.24]

A necessary condition for densification to occur is that the grain boundary energy 7gb be less than twice the solid/vapor surface energy This implies that the equilibrium dihedral angle 0 shown in Fig. 10.3 and defined as... [Pg.305]

In materials with high anisotropy in the grain boundary energy and, thus, with faceted grain boundaries, the angles between boundaries may not be uniquely defined by an interfacial tension condition because of torque on facets. ... [Pg.19]

The distribution of electromagnetic (EM) energy in MAE systems is determined by Maxwell s equations with suitable boundary conditions defined by the makeup... [Pg.2028]

With kinetic energies of 0.1 eV and lower, the polarization forces deform the rectilinear ion trajectories so that Eq. (32.5) is no more valid for the cross section of resonant charge exchange. In this case, the upper cross section boundary is defined by Eq. (32.3). [Pg.180]

It is 0 (n) that accounts for the energy contribution of the nucleus-substrate and the nucleus-solution interface boundaries and has the physical meaning ofthe concept surface free energy defined in this general form by Stranski in 1936 [1.12, 1.13]. [Pg.13]

A. rather complex procedure is used to determine the Born radii a values of which. calculated for each atom in the molecule that carries a charge or a partial charge. T Born radius of an afom (more correctly considered to be an effective Born radii corresponds to the radius that would return the electrostatic energy of the system accordi to the Bom equation if all other atoms in the molecule were uncharged (i.e. if the other ato only acted to define the dielectric boundary between the solute and the solvent). In Sti force field implementation, atomic radii from the OPLS force field are assigned to ec... [Pg.615]
