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 ...

Abstract Strategies that enable intermolecular site-selective C–H bond functionalisation of organic molecules provide one the cornerstones modern chemical synthesis. In chloroalkane synthesis, such methods for aliphatic chlorination have, however, remained conspicuously rare. Here, we present a copper(I)-catalysed synthetic method efficient C( sp 3 )–H ketones, ( E )-enones and alkylbenzenes by...

in this work, we report synthesis of silver nanoplates by a simple reduction process of silver nitrate in the presence of polyvinyl alcohol (pva) and n,n'-dimethyl formamide (dmf). the characterization of the samples were carried out using x-ray diffraction (xrd), transmission-electron microscopy (tem) and uv-vis spectroscopy. absorption spectra of the nanoplates in comparison with that of...

in this paper, we report on the synthesis of cu nanoparticles through a single-precursor route by controlling the growth temperature. selective adsorption of oleylamine on various crystal planes may play an important role in the growth process. the understanding of this self-assembling process will help us develop reliable and reproducible methods to synthesis other three dimensional nanostruct...

Selective deprotection of functional groups using different wavelengths light is attractive for materials synthesis as well achieving independent photocontrol over substrates in biological systems. Here, we show that mixtures recently developed visible light-absorbing BODIPY-derived photoremovable protecting (PRPGs) and a coumarin-derived PRPG can undergo wavelength-selective activation, giving...

An efficient synthesis of a highly potent and selective IP (PGI(2) receptor) agonist that is not structurally analogous to PGI(2) is described. This synthesis is accomplished through the following key steps: Nucleophilic ring-opening of 3-(4-chlorophenyl)-oxazolidin-2-one prepared by a one-pot procedure with 4-piperidinol and selective O-alkylation of 1-(2-(4-chlorophenylamino)ethyl)piperidin-4...

Selective synthesis of titanium dioxide (TiO2) polymorphs including anatase, rutile, brookite and TiO2(B) by solvothermal treatment of water-soluble titanium complexes is described with a special focus on their morphological control. The utilization of watersoluble titanium complexes as a raw material allowed us to employ various additives in the synthesis of TiO2. As a result, the selective sy...

A new family of duplex-forming recognition encoded oligomers, capable sequence selective duplex formation and template directed synthesis, was developed. Monomers equipped with both amine aldehyde groups were functionalized...
