In quantum mechanics, the energy of a confined system can take on only certain quantized values. An atom (the nucleus and the electrons) is a quantum system that follows this rule; its energy levels are discrete due to the nature of quantum mechanics. For any given atom, there are only s...

First, at homogeneous limit the local density becomes a constant, and then DFT naturally gives rise to the EOS inHelmholtztype (Chapman et al., 1989; Lemmon andJacobsen, 2005). Second, EOS can be developed with the knowledge of local structure throughVirial equation. Specifically, for the flu...
Donald L. Sparks, in Environmental Soil Chemistry (Second Edition), 2003 Freundlich Equation The Freundlich equation, which was first used to describe gas phase adsorption and solute adsorption, is an empirical adsorption model that has been widely used in environmental soil chemistry. It can be ex...
How do you calculate lattice energy using the Born Haber cycle? To calculate lattice energy using the Born-Haber cycle, the following values are required: the heat of formation of ionic solid, heat of vaporization, the electron affinity of anion element, ionization energy of cation element, atom...
(7) is used second to evaluate the entropy, and finally Eq. (5) is used to evaluate the internal energy. In fact, this procedure is almost too robust! The interpolated values may be a horribly inaccurate but they will be thermodynamically consistent. Here then are bzip2 tarballs of six ...
While the dose deposition of charged hadrons has received much attention over the last decades starting in 1930 with the publication of the Bethe equation, there are still practical obstacles in implementing it in fields like radiotherapy and isotope production on cyclotrons. This is especially true...
First one, proton beams were used to irradiate nanosphere with diameter of 100 nm. The beams passed through the center of NP. Only 10 protons were tracked for visualization in this case. The second one was similar to the first one except protons shooting the surface. In the third one, ...

In the second approach, a sequence of calculations with improving basis sets is done on one molecule until convergence is reached. The error is estimated from the sensitivity of the result to further refinements in the basis set. The calibrated method is the more practical for routine ...
