Interfacial polymerization of polyamide was conducted using hydrophobic and hydrophilic membrane support. The effects monomer concentration were investigated, the resulting thin-film composite membranes tested for their performance in dye removal different flow configurations. results showed that a dense layer successfully formed on support, while with very loose structure became smoother more ...

This paper proposes two different nanomolding methods to fabricate synthetic gecko foot-hair nanostructures. The first method uses Atomic Force Microscope (AFM) probe indented flat wax surface and the second one uses a nano-pore membrane as a template. These templates are molded with silicone rubber, polyamide and polyester type of polymers under vacuum and the template is peeled off or etched ...

In this report, experimental investigation of waste water treatment by reverse osmosis to enable its reuse in cooling tower is presented. A polyamide spiral wound RO membrane followed by three filters as RO pretreatment (two activated carbon and one cartridge filter) and samples of Tehran refinery treated waste water have been used. The effect of operating conditions such as pressure differ...

The objective of this work was to apply a hybrid process, including electrodialysis reversal (EDR) and reverse osmosis (RO) to the treatment of petrochemical wastewater in order to obtain process water for reuse. A water balance was carried out to defne the main water consumers and the process step that could receive the produced water. Additionally, toxicity assays wer...

The possibility of removing tetracycline (TRC) from water in an integrated advanced oxidation and membrane filtration process was investigated. Ozonation UV/H2O2 photooxidation were applied for the destruction TRC. Six products (OPs) retaining structural core TRC have been identified. One new product, not reported so far literature, identified—ethyl 4-ethoxybenzoate. All identified OPs effectiv...

High‐precision separation with increased water permeability is critical for efficient membrane‐based treatment processes. To achieve high selectivity toward different targeted species while allowing rapid transportation, the structure of membrane polyamide selective layer requires delicate regulation. Herein, an effective approach to systematically expand pore size layers by incorporating ammon...

The zinc finger protein EVI1 is causally associated with acute myeloid leukemogenesis, and inhibition of its function with a small molecule therapeutic may provide effective therapy for EVI1-expressing leukemias. In this paper we describe the development of a pyrrole-imidazole polyamide to specifically block EVI1 binding to DNA. We first identify essential domains for leukemogenesis through str...
