abstract = {Nanoparticles, exhibiting functionally relevant structural
heterogeneity, are at the forefront of cutting-edge
research. Now, high-throughput single-particle imaging (SPI)
with x-ray free-electron lasers (XFELs) creates
unprecedented opportunities for recovering the shape
distributions of millions of particles that exhibit
functionally relevant structural heterogeneity. To realize
this potential, three challenges have to be overcome: (1)
simultaneous parametrization of structural variability in
real and reciprocal spaces; (2) efficiently inferring the
latent parameters of each SPI measurement; (3) scaling up
comparisons between $10^5$ structural models and $10^6$
XFEL-SPI measurements. Here, we describe how we overcame
these three challenges to resolve the non-equilibrium shape
distributions within millions of gold nanoparticles imaged
at the European XFEL. These shape distributions allowed us
to quantify the degree of asymmetry in these particles,
discover a relatively stable `shape envelope' amongst
nanoparticles, discern finite-size effects related to
shape-controlling surfactants, and extrapolate
nanoparticles' shapes to their idealized thermodynamic
limit. Ultimately, these demonstrations show that XFEL SPI
can help transform nanoparticle shape characterization from
anecdotally interesting to statistically meaningful.},
