Inelastic X-ray scattering techniques with resolution power exceeding 104-107 are being used to study electronic and collective behavior materials under extreme conditions of heat, pressure and magnetic field. In this presentation, we will review how various inelastic x-ray scattering techniques can shed light to characteristics of materials at macro- and nano-scales. These include study of monolayers or interfaces, impurities, materials under extreme pressure, and liquids at elevated temperatures. Newly developed techniques incorporate highly monochromatic and tunable synchrotron radiation with crystal monochromators and analyzers. This talk will focus on both resonant and non-resonant momentum resolved or integrated inelastic x-ray scattering, as well as nuclear resonant inelastic x-ray scattering, and their applications for materials under high pressure. Future prospects for pushing the limits of these techniques on an Energy Recover Linac type machine will also be presented.
