Electron Energy Loss Spectrum
http://han.ess.sunysb.edu/EELS
This program calculates the Electron Energy Loss Spectrum (EELS). To use this code, first use script " script EELS. To generate input for this code. To use in conjuction with USPEX - ONLY FOR VASP CODE. Remember to use this utility, user must specify few VASP tags in the INCAR file for the last stage of VASP calculations, such as:. LOPTICS = .TRUE. CSHIFT = 0.01 NEDOS = 2000 NOMEGA = 100 OMEGAMAX = 20 OMEGATL = 260. Should you have any question, feel free to contact Prof. Priya Johari.

Hardness calculation
http://han.ess.sunysb.edu/hardness
The webpage is to calculate hardness. Allows the calculation of the hardness. It involves the concept of hybrid global optimization, where global optimization with respect to the hardness is conducted in the space of local minima of the (free) energy. The Lyakhov-Oganov model is based on the model of Li et al. (PRL 2009). To calculate hardness. We used the formula for the Knoop hardness (in GPa):. Is the volume of the unit cell and. Is the number of bonds of the type. In the unit cell. The most defining ...

Multifingerprint
http://han.ess.sunysb.edu/multifingerprint
This program calculates average quasi-entropy, A-order and S-order for a set of structures. Also it filters unique structures by cosine distances difference ≥ 0.003, identifies the symmetry of the resulted structures and lists them in the. It is based on fingerprints code. Mg, Al, O atoms).

Fingerprints
http://han.ess.sunysb.edu/fingerprints
Fingerprint function is a crystal structure descriptor, a 1D-function related to the pair correlation function and diffraction patterns. It does not depend on absolute atomic coordinates, but only on interatomic distances. Small deviations in atomic positions will influence fingerprints only slightly. Fingerprint theory (Oganov and Valle, 2009) allows quantification of the degree of order and complexity of a crystal structure. One could also measure the similarity between structures.
