In situ TEM diffraction of Pd hydrogen adsorption

In-situ TEM diffraction pattern at 0.8 bar hydrogen gas pressure monitors Pd-H phase transition upon temperature change due to hydrogen absorption into the Pd-H lattice. Note that different diffraction spots coming from different Pd-H particles (200 nm size) change at different moments.
