Home / Methodology
The goal is to answer the scientific question — not merely to fit peaks
Many materials contain disorder, nanoscale effects and local distortions that stay hidden in an average crystallographic model. We combine reciprocal-space and real-space methods to investigate materials across length scales, and we report what the data can and cannot support.
Four steps
How an analysis is approached
Define the question
What structural information do you need — and what decision will it inform?
Choose the method
PXRD, total scattering, PDF or advanced modelling, depending on the length scale of interest.
Analyse & model
Reproducible processing, refinement and interpretation.
Deliver insight
Results, figures and a clear scientific explanation, including limitations.
Quality
Validation, uncertainty and reproducibility
Validation
Data are checked before they are modelled — normalisation, corrections and instrument resolution — and fits are judged by residuals and physical plausibility, not by a single agreement factor.
Uncertainty
Refined values are reported with their uncertainties, and we state which parameters are well determined by the data and which are not.
Competing models
Where more than one structural picture is possible, alternatives are compared against the same data rather than a single model being assumed.
Reproducibility
Processing steps, models and key parameters are documented so that the analysis can be repeated, checked and extended — by you or by us.
Experience
Instruments and facilities
We work with data from synchrotron and neutron facilities and from laboratory diffractometers, in the formats common to these instruments. If your data come from a specific beamline or instrument, tell us in your enquiry and we will confirm that we can handle them.
Discuss your dataset
Tell us about your material, data and scientific question. We will assess the project and propose an appropriate analysis strategy. No commitment is required at this stage.
