Separation Efficiency of Epoxified-Polyethersulfone Blend Membrane for Chromium Removal

A microporous bisphenol A diglycidyl ether (DGEBA) epoxified-polyethersulfone (PES) blend membrane (EPES membrane) was prepared through dry-wet phase inversion. This study attempts to correlate the changes in membrane physical and chemical properties when the EPES membranes were exposed to different durations of dry-phase inversion, towards the separation efficiency of carcinogen chromium (VI)....

Development of Palladium-Alloy Membranes for Hydrogen Separation and Purification

This paper summarizes R&D activities and progress at NORAM Engineering and the University of British Columbia (UBC) on preparation and testing of thin palladium-based membranes and their applications. Most of these activities were carried out internally at NORAM, some jointly with UBC and their spin-off company, Membrane Reactor Technology (MRT) through a wide range of projects. Key results out...

High-throughput, Continuous-flow Separation of Biomolecules in a High- aspect-ratio Nanofilter Array

We have developed a novel fabrication ap proach to generate massively-parallel, highaspect-ratio vertical nanofluidic channels with smooth, vertical sidewalls and precise control of uniform gap sizes (lateral trench width) down to 50 nm (Figure 1) [1]. The aspect ratio can be as high as 400 and the channel depths are more than 20 μm. This technique enables us to fabricate a large area of solid ...

Nanofluidic Molecular Filters for Size-Separation of Biomolecules

Micro/nanofluidic molecular sieving structures[1] have great potential for faster molecular separation. However, their use has been largely limited to big molecules such as DNA, since it is rather challenging to fabricate structures with near-molecular dimensions. We present a novel separation method using nanofluidic filters, which is based on the steric hindrance effect of molecules[2-4]. Whe...
