TL;DR: In this article, a femtosecond powder X-ray diffraction was employed to measure the lattice deformation in the phase transition as a function of time, and the early intra-cell distortion around the light absorbing metal dimer and the long range deformations governed by acoustic waves propagating from the laser-exposed Ti3O5 surface.

TL;DR: It is shown how strain waves, launched by electronic and structural precursor phenomena, determine a coherent macroscopic transformation pathway for the semiconducting-to-metal transition in bistable Ti3O5 nanocrystals.
Light-Induced Spin State Switching in Copper(II)-Nitroxide-Based Molecular Magnet at Room Temperature
TL;DR: An ultrafast SS → WS photoswitching was for the first time demonstrated at room temperature, constituting an important milestone in the development of copper(II)-nitroxide molecular magnets for practical purposes.

TL;DR: These studies show that LIESST in [Fe(L222 N5 )(CN)2 ] occurs on the 100 fs timescale under different types of photoexcitation, and coherent oscillations were observed, resulting from the structural dynamics accompanying LIES ST, which were recently evidenced in more conventional octahedral FeII N6 systems.
