How to find that the atom is in interstitial or substitution lattice from FT-IR
From Na2S and MgSO4 which can be considered as chalcogenides elements. And Sulphates like FeSO4, CaSO4,etc. (SO4-) are chalcogenides?

Hi, I am using GROMACS 5.1.4 to simulate water in contact with a surface. I am only interested to calculate some properties of water near the surface. Let's say at a distance of x nm from the...

(This statement is from wikipedia, BTW). What is so special about metallic bond that is limiting high-P low-T state of a matter (as long as individual atoms exist, not white dwarf of neutron star...

during MD simulation, the atoms are not moving as per required. The problem (as per my observation) lies in energy minimization technique. upon application of tensile strain in x or y direction,...

MAGNETISMIC GRAVITY What is magnetism? Something magnetic has a + and - charge. If 2 + or - are pushed if + and - are pulled. But what is the main reason for this? Why does magnetism have a pull...

Additional questions are: What are the encapsulating atoms? How difficult was the process and what rates were achieved? What factors most seriously affect the economics?

I am trying to simulate contact angle of water on a quartz slab using LAMMPS. I have created and equilibriated the quartz slab and the water cluster separately. Now I want to create a composite...

Hello all, as I understand there isn't any straight way to get an rdf of atoms from the center of mass or a coordinate of specific atoms in lammps. I wonder if anyone know any trick or way to get...
