Fig. 4. Porosity size/size-distribution derived from PALS for neat liquids silicone oil, olive oil, and polyethylene glycol, (PEG) vs. ZIF-8/liquid dispersions in those liquids: (a) 〈τo-Ps〉> – average o-Ps lifetime, a measure of the average pore size; (b) σo-Ps – width of o-Ps lifetime distribution indicating a spread around 〈τo-Ps〉; (c) 〈vh〉 – average pore volume derived from 〈τo-Ps〉; (d) σh – spread of pore volume around 〈vh〉.
