For sodium chloride, the solid is more stable than the gaseous ions by 787 kJ mol-1, and that is a measure of the strength of the attractions between the ions in the solid. Remember that energy (in this case heat energy) is given out when bonds are made, and is needed to break bon...

Visit“What is Bragg’s Law and Why Is It Important?”for more details on the Bragg equation and a simulator that allows you to explore the effect of each variable on the intensity of the diffracted wave. An X-ray diffractometer, such as the one illustrated in Figure 20, may be used...
One of the most accurate approaches for calculating lattice thermal conductivity, $$\kappa _\ell$$ DMPSID=1 , is solving the Boltzmann transport equation starting from third-order anharmonic force constants. In addition to the underlying approximations o

A method for gleaning information about Nn is to contemplate the Poisson equation with a crystal charge source, modeled after NaCl (salt) in the sense of alternating lattice charges: ∇2φn(r) = − (−1)1·mδ(m − r). m ∈ Zn (9) Accordingly—based on the Poisson equation...
