Use of porous anodic alumina membranes as a nanometre-diameter column for high performance liquid chromatography

Abstract

The possibility of using porous anodic alumina membranes as a column for normal-phase high performance liquid chromatography was evaluated using phenol and toluene with mobile phases having different solvent compositions.

Fabrication and characterization of mesoporous silica nanochannels inside the channels of anodic alumina membrane

“…Their unique uniform pores ranging from a few to tens nm in diameter and stability in organic and inorganic solution phases could shed light on a plethora of different promising applications such as size-exclusive separation (Yamaguchi et al, 2004;El-Safty et al, 2010;Mekawy, 2011), enzymatic nanoreactors (Fu et al, 2008Mekawy et al, 2011, sensors (El-Safty et al, 2008a,b) and nanofluidic devices (Yamashita et al, 2007).…”

Polyrhodanine modified anodic aluminum oxide membrane for heavy metal ions removal

“…Recently, several studies have been reported that the AAO membrane could be used as a membrane itself (without etching process) [18,19]. As a filter, the AAO membrane provides uniform channels, facile controllable pore size and large surface area.…”

Mesoporous silica hybrid membranes for precise size-exclusive separation of silver nanoparticles

“…Due to their uniform pores, ranging from a few to tens of nanometers, and their hydrothermal stability in organic and inorganic solution phases, nanoporous materials have been anticipated for size-exclusive separation [4], enzymatic nanoreactors [5], sensors [6], and nanofluidic devices [7]. Since the fabrication of the classic MS41 nanomaterials [1a], significant effort has been expended in creating new levels of hierarchical materials with controlled structural geometry, mesophase morphology, and mesopore size and shape by varying the surfactant templates and synthesis conditions [1][2][3].…”
