More specifically, the designs “have distinct conductances that correlate with their pore diameter, ranging from 110 picosiemens (~0.5 nanometer pore diameter) to 430 picosiemens (~1.1 nanometer ...

Rock candy, where sucrose molecules form crystals via hydrogen bonds, is a simple example. Endowing molecular crystals with porosity unlocks vast potential for gas separation, sensing, and catalysis.

Two decades ago, the "Mean Girls" movie told us all that pore size was yet another beauty standard we weren't living up to. "My pores are huge," Regina George (Rachel McAdams) complains ...
