Diffusion and Filtration Properties of Self-Assembled

We report the first measurements of molecular transport through such ultrathin sheets, self-assembled from dodecanethiol-ligated gold nanocrystals. For aqueous solutions we find filtration coefficients 2 orders of magnitude larger than those observed in polymer-based filters, sieving of large solutes, and for smaller solutes a pronounced dependence of rejection on being charged.

Gold parting - Wikipedia

Gold parting is the separating of gold from silver. Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum. With the advent of coinage, methods had to be invented to remove impurities from

Novel antibody/gold nanoparticle/magnetic nanoparticle ...

During the filtration, the cells bound to the antibody/AuNP/MNPs remained on the surface of the membrane filter while unbound nanoparticles passed through the uniform pores of the membrane. After the gold enhancement, the cells-particles complex resting on the membrane surface rendered a visible color, and the signal intensity became higher as the target cell concentration increased.

Filtration Definition and Processes (Chemistry)

29-01-2020  Cold Filtration: Cold filtration is used to quickly cool a solution, prompting the formation of small crystals. This is a method used when the solid is initially dissolved . A common method is to place the container with the solution in an ice bath prior to filtration.

Gel Filtration Column Bio-Rad

Gel Filtration Columns Enable Separations Not Achievable by Other Methods. A gel filtration column separates molecules and complexes by size. The separation is not strictly by molecular mass, since the shape of the molecule or complex can affect migration through the column.
