How many crystal forms of HCl have been identified - where to find the unit cells/lattice constants?
What material properties are unpredictable (not reproducible) but can be measured consistently and at a low cost?
Given a CIF (crystallographic interchange format) file (and thus cartesian atomic coordinates), how can you find the bonds between atoms?
Why does Samarium have such a large c-axis lattice constant? (>26 Å) Are there significantly larger lattice constants of the elements?
Do we really have technology with the resolution to distinguish between layers of single atoms of materials?
