Claudio Mazzoli will present some opportunities of scientific investigation by micro-spectro-scattering in the soft X-ray regime of Resonant X-ray Scattering, as implemented and developed at CSX (the Coherent Soft X-ray scattering beamline of NSLS-II, BNL). The peculiarity of such an integrated approach in terms of space, time, energy scales, and correlations, allows revealing unique properties of materials from the microscopic point of view, and shining new light on a variety of interesting cases. Electronic orderings, inhomogeneities, self-organization, collective dynamics and interplay of degrees of freedom will be presented, together with some future ideas.
