Progress has been halted in a number of critical fields because it is challenging to make quantitative in-situ measurements at the nanoscale. Recent advances in synchrotron based nano scale X-ray imaging have made it possible to map in-situ structure and chemistry of fluid based reactions. This work will present methodologies to combine nano computed tomography and fluorescence mapping to produce 5D data sets at a ~50 nm resolution. The results give quantitative measurements of 3D structure, chemistry and mass density of the changes that occur over time. Next, data from a specialized flow through cell will be presented that allows time resolved, in-situ chemical mapping of changes in the material surface and the surrounding solution. A case study will be presented for calcium silicate reactions in different solutions; however, these methods can be applied to many different materials to allow improved understanding of nanoscale phenomenon.
