"MOFs have shown a lot of promise because of their porosity and their structural versatility."

“You can see there's a lot of porosity.”

She then paired these historic specimens with modern samples from the same sites and conducted a series of comparisons including the thickness of the shells, their surface area and volume, and density and porosity.

Finally, each device is coated in zinc oxide nanowires which give the emitter a level of porosity that enables it to effectively filter and transport liquids.

They also noted that the porosity of the aggregate likely contributes to the paraffin remaining a liquid below its usual freezing temperature of 42 degrees Fahrenheit.
