Assessment of data mined from the literature. (a) Map of processing conditions. Data points are color coded by the ligament diameter, ranging from red for 2.6 ± 1.3 nm to light blue for 1630 ± 770 nm. The dashed lines are approximate isocontours of the ligament diameter. (b) Calculated ligament diameters plotted against reported ligament diameters. The plot excludes six data points – with reported ligament diameters of 100, 140, 200, 480, 589, and 940 nm – to clearly compare data in the 2–70 nm range.
