Extended Data Fig. 8

a,b, The two-dimensional geometry models for a pristine control device (only covered by EVA film on the metal side; a) and a device including one coated with DMDP film on the glass-side alone (and the metal side is covered with EVA; b). c,d, The simulated spatial Pb concentrations for a pristine device (c) and a DMDP-coated device after 180 min of damage by shattering the glass side and forming cracks in the glass/DMDP (d). The labelled dimensions are in mm, and the colour-scale numbers are in ppm. Note that the colour scale ranges are different in c and d.
