Oily waste is hard to deal with as regular filters either let the oil pass through or become clogged easily, rendering them useless. Perdue researchers have developed a new oil filtration material and technique that can easily remove 98% of oil on the first pass, and the oil itself is easily collected and removed from the filter.

The membrane consists of a layer of material called polyethylene glycol, and each molecule is tipped with a Teflon-like "functional group" made with fluorine. Water molecules are attracted to the polyethylene glycol, yet pass through the Teflon-like layer, which acts as a barrier to the oil molecules. ed.z.: hope this hits the civvie market soon, this is a needed product.

Spelling?

Not to pick nits, but the University is "Purdue", while the chicken company is "Perdue".

This is why the rearranged log T-Shirt is spelled "Undue Purversity" :-)

But that aside, this is a really needed product, especially for oil spill cleanup, but also for storm sewers of parking lots, car repair operations, etc.
