The impressive precision with which particles can be localized, down to ±1.5 nm but more typically tens of nanometers, depends generally on localization of a tag rather than the molecule of ...

Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. This is due to the random movement of the ...

Diffusion is the movement of particles from ... and is one of the ways substances can move across the cell membrane, into or out of the cell. Products of digestion, dissolved in water, can pass ...

Materials being examined currently are the electrolyte membrane, gas diffusion layer, catalyst, and ionomer. We examine material function at glucose concentrations similar to physiological levels to ...

Many scientifically challenging problems have to be solved in order to make them cost effective and thus commercially viable. In this project, novel designs of gas diffusion layer and catalyst support ...

The fabric uses molecular diffusion, rather than micropores ... isn’t new,” admits a Polartec statement, adding that a “membrane that can layer within technical fabric and withstand ...
