Preparation of Novel Thin-Film Composite Nanofiltration Membranes for Separation of Amoxicillin
Several novel composite membranes were prepared to separate and recycle amoxicillin from pharmaceutical wastewater via nanofiltration process. The synthesis of these membranes included three stages: 1- preparation of polysulfone ultrafiltration membranes as a support via phase separation process, 2- modification of its surface by interfacial polymerization as a selective layer (polyamide), and ...
متن کاملRecA polymerization on double-stranded DNA by using single-molecule manipulation: the role of ATP hydrolysis.
The polymerization of RecA on individual double-stranded DNA molecules is studied. A linear DNA (lambda DNA, 48.5 Kb), anchored at one end to a cover glass and at the other end to an optically trapped 3-micrometers diameter polystyrene bead, serves as a template. The elongation caused by RecA assembly is measured in the presence of ATP and ATP[gammaS]. By using force extension and hydrodynamic ...
متن کاملMicrotubule Assembly Dynamics at the Nanoscale
BACKGROUND The labile nature of microtubules is critical for establishing cellular morphology and motility, yet the molecular basis of assembly remains unclear. Here we use optical tweezers to track microtubule polymerization against microfabricated barriers, permitting unprecedented spatial resolution. RESULTS We find that microtubules exhibit extensive nanometer-scale variability in growth ...
متن کاملPolymerization-induced thermal self-assembly (PITSA)† †Electronic supplementary information (ESI) available: Experimental details, characterization data, and additional figures. See DOI: 10.1039/c4sc03334e Click here for additional data file.
Polymerization-induced self-assembly (PISA) is a versatile technique to achieve a wide range of polymeric nanoparticle morphologies. Most previous examples of self-assembled soft nanoparticle synthesis by PISA rely on a growing solvophobic polymer block that leads to changes in nanoparticle architecture during polymerization in a selective solvent. However, synthesis of block copolymers with a ...
متن کاملColloidal polymerization of polymer-coated ferromagnetic nanoparticles into cobalt oxide nanowires.
The preparation of polystyrene-coated cobalt oxide nanowires is reported via the colloidal polymerization of polymer-coated ferromagnetic cobalt nanoparticles (PS-CoNPs). Using a combination of dipolar nanoparticle assembly and a solution oxidation of preorganized metallic colloids, interconnected nanoparticles of cobalt oxide spanning micrometers in length were prepared. The colloidal polymeri...
