Genetic Algorithm Based Optimization of Baffle Positions in a Forward Osmosis Draw Channel
<p>Forward Osmosis (FO) driven asymmetric membrane filtration is a developing technology which shows promise for seawater desalination and wastewater treatment. Due to the fact that asymmetric membranes are widely used in conjunction with this technology, internal concentration polarization (ICP), …

Synthesis and Characterization of Disulfonated Poly(Arylene Ether Sulfone) Random Copolymers as Multipurpose Membranes for Reverse Osmosis and Fuel Cell Applications
… poly(arylene ether) random copolymer membranes in fuel cell and reverse osmosis applications. Poly(arylene ether)s were prepared by direct step copolymerization using a third monomer 3,3–-disulfonated 4,4–-dichlorodiphenylsulfone. The membrane properties of a 4,4–-biphenol-based …

Consequences of Asymmetric Environment on the Mechanics of Lipid Bilayer
Lipid membranes are selective barriers that encapsulate cellular components and define the identity of organelles. A fundamental feature of membranes is an asymmetric distribution of lipids and proteins across them. While a basic level of asymmetry is maintained at all times, local and transient …

Design and fabrication of asymmetric nanopores using pulsed PECVD
… the application of pulsed PECVD to fabricate asymmetric nanopores. In contrast to ALD, pulsed PECVD does not result in perfectly conformal deposition profiles, and predicting the final nanostructure is more complicated. A two dimensional feature scale model was developed to predict film …

An Investigation of Pore Collapse in Asymmetric Polysulfone Membranes
Porous polysulfone membranes prepared by phase inversion can be tailored to suit filtration requirements by the choice of solvent and coagulant. In the current research polysulfone membranes were prepared by inverting a solution in N-methyl pyrrolidinone (NMP) in isopropanol to form uniform sized …

Design of chemically treated activated carbon fibers for mercury removal and advanced membranes for water purification
… other one is to design advanced nanofiltration membranes for water purification with specific features, i.e. solvent resistance and antifouling properties. The current technologies for mercury removal involve the use of chemically treated activated carbon powder has had limited success. These …

Structure Formation Mechanism of Isoporous Block copolymer Membranes
… induced phase separation by immersion in water, asymmetric membranes consisting of a thin top layer with closely packed pore channels with diameters below 100 nm above a much thicker macroporous supporting layer are formed. These membranes can be used for filtration purposes of, e.g., …
