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

The outer membrane of mitochondria and chloroplasts has pores that allow small molecules to pass easily. The inner membrane is loaded with the proteins that make up the electron transport chain ...

The investigators studied the membrane-targeting sequence (MTS) of bactofilin A (BacA) in Caulobacter crescentus to explore its role in membrane binding and polymerization. They used various ...

Nanoporous membranes with atomic ... The concentration of the pores and even their sizes can be determined in advance. The team was able to tune the size of the pore from 4 nanometers to smaller ...

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 ...

Their general measurement speed and easy operation make these capillary flow porometers the ideal choice for through-pore size distribution measurements of filtration media. Based on the pore size ...

"Those slower solutes appear to be rejected by the membrane. Counter-intuitively, objects even half the size of the pore will end up being rejected about half the time." Overcoming rejection ...

Researchers at Imperial College London, supported by colleagues at a range of other institutions, have published a study in ...

Despite what you might have heard, pores are virtually impossible to eradicate. However, if you’d like to minimize the size of pores, there are certain ways you can achieve it. Need some more ...

Space-based telescopes are remarkable. Their view isn't obscured by the weather in our atmosphere, and so they can capture ...
