Question: Strontium titanate (SrTiO3) is a rare oxide mineral found naturally in tausonite crystals in Siberia. Because it has an index of refraction value similar to that of diamond (n=2.41), it is often used as a diamond substitute. Were it not for its greater physical density and greater softness, a jeweler would have difficulty distinguishing between diamond and

Question: The crystal structure of SrTiO3 is cubic, with a unit cell edge a = 3.90 Å. Calculate the expected 2θ positions of the first three peaks in the diffraction pattern which correspond to the planes (100), (110), (111) if the radiation is Cu Kα (λ= 1.54 Å).

SrTiO3 The structure factor represents the scattering of x -rays from the periodic arrangement of atoms within a particular crystal structure. Using the atomic positions for the atoms within the unit cell, you can calculate the (hkl) planes will result in constructive interference conditions from the lattice and their relative intensities.

Question: Critical Thinking III) Identify whether the arguments below are deductive/inductive, valid/invalid or strong/weak. Simple explanation for each question is preferred. 1. All employees having same salary is a good idea because this should keep their minds focused on the job rather than on what the colleague sitting next to them is earning. * deductive,
