The inherently uniform nanoporous architecture of self-organized anodic alumina makes it a promising platform for ceramic membranes with extremely narrow pore size distribution tunable in the 1 to 300 nm range. The alumina ceramic is chemically inert and resistant to high temperatures. These features provide multiple opportunities for developing a portfolio of membrane products for applications from gas separation, catalytic membrane-reactors and membrane standards to membranes for ultra- and nanofiltration, bioseparation and bioanalysis.
