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...

Developing thin-film nanocomposite (TFN) membranes by incorporating nanomaterials into the selective polyamide (PA) layer is an effective strategy to improve separation and antibacterial properties. In this study, TFN nanofiltration (NF) were fabricated interfacial polymerization of piperazine (PIP) trimesoyl chloride (TMC) with addition Zinc-Iron-Cerium (ZnFeCe) layered double hydroxide (LDH)....

Among current separation processes, nanofiltration (NF), besides its easy scalability, exhibits low energy consumption, environmental impact and footprint, being widely used for water treatment solvent recovery. The development of membranes NF involves perfecting the skin selective layer, sublayers support. In this work, a multilayer structure membrane is presented where layer polyamide (PA, th...

Hydrogen bond directed folding of a synthetic polyamide was studied in chloroform solution, and the three-dimensional structure of the foldamer determined using 1H NMR chemical shifts.

this study focuses on the preparation and modification of a thin-film composite (tfc) hollow fiber polyamide membrane fabricated by the interfacial polymerization of piperazine (pip) and trimesoyl chloride (tmc) on a porous polysulfone substrate. the effects of triethylenetetramine (teta) and silica nanoparticles (sio2) contents in the aqueous phase (as the additives) on the morphology and perf...
