Explain the process of twinning with respect to crystal structures.

Why do so many metals adopt the same structure type, while there is a much larger variety for ionic compounds and even more for molecular crystal structures?

Metal structures commonly adopt one of three common structure types, ccp, hcp and bcc. What are the differences and similarities between these structure types?

Which diffraction method(s) would you use to investigate a positive electrode material for a Li-ion battery?

What alternatives are there to Li-ion batteries and what are their advantages and disadvantages?

What is the reaction equation for the reaction of Sr0.75Ti0.5Nb0.5O3 with n-butyllithium in hexane? Consider oxidation states.

What are the differences between cubic stabilised zirconia (CSZ) and partially stabilised zirconia (PSZ)? Compare and contrast.

What is the difference between intrinsic and extrinsic defects? Which are likely to lead to higher ionic conductivity and Why?

Which structure types are particularly suitable for superionic conduction?

150g of a gas at 10.0°C and 1.0 atm pressure occupies 913L volume. The volume of the gas increases to 988L and its temperature increases to 41.5°C while the pressure remains constant. Calculate ΔE, q and w for the gas. (Specific heat of the gas = 5.2J/g°C and 1L.atm = 101.3J). [4 marks]
