ac TEM images of early valve SDVs with associated ~ 20 nm sized spherical nanoparticles. Scale bars: 200 nm. d Scanning transmission electron microscopy (STEM) EDX analysis of several nanoparticles within a single valve SDV. The yellow circles in the STEM image highlight the nanoparticles from which the EDX spectrum was obtained. The elemental maps are depicted with the corresponding chemical symbol. Scale bars: 100 nm
