In this study, acicular nano-hydroxyapatite (n-HA) was used to make a new biomimetic composite with polyamide (poly hexamethylene adipamide) by a unique technique. The physical and chemical characteristics of the composites were tested. It was found that these synthesized n-HA crystals were similar to bone apatite in size, phase composition and crystal structure. The biomimetic n-HA crystals we...

The Nucleosome Core Particle (NCP) is the minimal unit in eukaryotic chromatin and a unique target for DNA-binding polyamides. The ability to modulate the stability of nucleosomes would be a useful tool for molecular biology and gene regulation. A series of polyamide clamps designed to differentiate between the NCP and B-form DNA were synthesized and analyzed using DNase I footprinting. In addi...

Since the advent of thin-film composite polyamide membranes brought forth a breakthrough in desalination and water purification nearly half century ago, recent years have only witnessed marginal improvements water-salt selectivity these membranes. The slow progression is partly attributable to limited understanding membrane synthesis–structure–performance relationships. A centralized archive re...

Thin film composite (TFC) membranes easily suffer from fouling induced by oil and other pollutants during forward osmosis (FO) due to the relatively hydrophobic chemistry rough structure of polyamide (PA). To achieve comprehensive anti-fouling properties, poly(2-methacryloyloxyethyl phosphorylcholine-co-2-aminoethyl methacrylate hydrochloride) (MPC-co-AEMA) was immobilized on top a polyketone (...

In this study, novel thin-film nanocomposite (TFN) membranes were developed by incorporating graphene oxide (GO) and Aquaporin Z (AqpZ) reconstituting nanostructure (AQN) into the polyamide (PA) active layer to improve forward osmosis (FO) performances of PA TFN membranes. First, AQN loading in was optimized, followed GO addition at various loadings until optimal FO process performance attained...
