Abstract: An overview of nanoscale x-ray imaging is presented with applications to broad areas of science, based onresults at several laboratories worldwide. Areas of application include the life sciences, materials science, environmental sciences, archeology, and industrial tomography. Present studies at synchrotron radiation facilities achieve 10 nm spatial resolution, with both soft and hard x-rays, but are relatively static, with exposure times measured in seconds. However, free electron lasers (FELs) are just becoming available that will allow dynamical x-ray studies to 10's femtoseconds, a path already pursued at longer EUV wavelengths with laboratory scale high harmonic techniques.
