Although the holes are too small to be seen with an electron microscope, their size has been measured experimentally ...

Concrete inevitably contains pores and microcracks with size ranging from the nanometre to millimetre scales. The pore structure controls all major properties of hardened concrete including durability ...

Membrane attack complex/perforin/cholesterol-dependent cytolysin (MACPF/CDC) proteins constitute a major superfamily of pore-forming proteins that act as bacterial ...

Shao, P. , Huang, R. Y. M. , Feng, X. , & Anderson, W. . (2004). Gas-liquid displacement method for estimating membrane pore-size distributions. AIChE journal, 50 ...

If a pore size in a membrane is comparable to the size of atoms and molecules, they can either pass through the membrane or be rejected, allowing separation of gases according to their molecular ...

This approach, which can produce pore sizes down to tens of nanometers, has found wide use in filtration. Increasingly though, researchers are looking to create ion-selective membranes by tweaking ...

The global reverse osmosis membrane market size was valued at $6.9 billion in 2017, and is estimated to reach $13.5 billion by 2025, registering a CAGR of 8.7% from 2018 to 2025. In 2017, the ...

Membrane pores, channels, and transporters are critical components in cellular physiology, playing essential roles in the regulation of ion and molecule passage across biological membranes. Despite ...

Nearly all commercial membranes are polydisperse, which means that their pore sizes are not consistent. For these membranes, it's nearly impossible to do a sharp separation of materials as ...
