but basic science challenges frustrate widespread deployment of polymer membranes for water purification in applications important for energy. For example, current membranes lack selectivity for some contaminants, and membrane performance is always reduced by fouling, or clogging, of the membrane surface or...

Chemical analysis, chemistry, determination of the physical properties or chemical composition of samples of matter. A large body of systematic procedures intended for these purposes has been continuously evolving in close association with the developmen
Some other alternative methods—low-temperature drying for water determination; Bradford, Lowry, and biuret methods for protein; the Folch and the Bligh and Dyer methods for fat; and enzymatic and reducing sugar methods for total sugar—appear likely to produce substantial error in marine mammal ...
