We are about to submit a detailed pair distribution function study of a new lead-free ferroelectric material based on RMC analysis. This method will be applied in VT studies of the local structure of the new fuel cell cathode and lead-free ferroelectric materials discussed above. Here variable temperature data is necessary in order to try and separate dynamic from static features of the disorder present in these complex materials as well as to obtain information closer to operating conditions for fuel cell cathodes and around the ferroelectric transition in the lead-free materials.
