      abstract     = {Home-based soft X-ray time-resolved scattering experiments
                      with nanosecond time resolution (10 ns) and nanometer
                      spatial resolution were carried out at a table top soft
                      X-ray plasma source (2.2-5.2 nm). The investigated system
                      was the lyotropic liquid crystal
                      C(16)E(7)/paraffin/glycerol/formamide/IR 5. Usually, major
                      changes in physical, chemical, and/or optical properties of
                      the sample occur as a result of structural changes and
                      shrinking morphology. Here, these effects occur as a
                      consequence of the energy absorption in the sample upon
                      optical laser excitation in the IR regime. The liquid
                      crystal shows changes in the structural response within few
                      hundred nanoseconds showing a time decay of 182 ns. A
                      decrease of the Bragg peak diffracted intensity of $30\%$
                      and a coherent macroscopic movement of the Bragg reflection
                      are found as a response to the optical pump. The Bragg
                      reflection movement is established to be isotropic and
                      diffusion controlled (1 micros). Structural processes are
                      analyzed in the Patterson analysis framework of the
                      time-varying diffraction peaks revealing that the
                      inter-lamellar distance increases by 2.7 A resulting in an
                      elongation of the coherently expanding lamella crystallite.
                      The present studies emphasize the possibility of applying
                      TR-SXRD techniques for studying the mechanical dynamics of
                      nanosystems.},
