A molecular imprinted polymer (MIP) was computationally designed and synthesized for the selective extraction of metaproterenol (MTP), from human plasma. In this regards semi empirical MP3 and mechanical quantum (DFT) calculations were used to find a suitable functional monomers. On the basis of computational and experimental results, acrylic acid (AA) and DMSO:MeOH (90:10 %V/V) were found to b...

This paper addresses the issue of selective disclosure of verifiable content. It extends previous work relating to Content Extraction Signatures [21] to implement a more complex structure that encodes a richer, more flexible fragment extraction policy, which includes fragment grouping. The new extraction policy enables the signer to specify both optional and mandatory fragment associations (or ...

Structural control of Schiff base ligands for selective extraction of copper(II) was investigated by changing pendant arms and the distance between two imine-N donor atoms in ligands. Di-Schiff base ligands, N,N'-bis(2-quinolylmethylidene)-1,2-diiminoethane (BQIE), N,N'-bis(2-pyridylmethylidene)-1,3-diimino-2,2-dimethylpropane (BPMP) and N,N'-bis(2-quinolylmethylidene)-1,3-diimino-2,2-dimethylp...

Highly rapid and selective vortex-assisted liquid-liquid microextraction based on solidification of organic drop has been used for determination of cobalt ion. 2-Nitroso-1-naphthol (2N1N) was used as a selective complexing agent to form stable cobalt-2N1N complex which can be extracted with 1-undecanol at a short time by the assistance of vortex agitator system followed by its determination usi...

Molecular imprinting technique offers a means of producing practical materials that are able to recognize a certain molecule in terms of shape, size and chemical functionality. In order to obtain a highly selective recognition of organophosphorus pesticides (OPPs), we synthesized molecularly imprinted polymers (MIPs) using pirimiphos-methyl as the template, methacrylic acid as the monomer and e...

The selective recognition/extraction of semiconducting (sem)- and metallic (met)-single-walled carbon nanotubes (SWNTs) is still a great challenge in the science and technology of carbon nanotubes because their selective synthesis is still difficult. Poly(9,9-dioctyl-fluorene-2,7-diyl) (2C8-PF) and its derivatives are widely used polymers in carbon nanotube science and technology since they onl...

A new simple and reliable method for rapid and selective extraction and determination of trace levels of Zn(II) ion is developed. Zn(II) ions are adsorbed quantitatively during passage of aqueous samples through PET-AA/AAm nano fiber modified. Almost all matrix elements were found to pass through the nano fiber to drain. Modified Poly (ethylene terephthalate)-grafted-Acrylic acid/Acryl amide Na...

a novel and selective method for the fast determination of trace amounts of zn(ii)ions in water samples has been developed.  the first additional carbonyl and carboxyl functionalized-nano graphene (spfnano graphene). the presence of additional carbonyl and carboxyl groups located at the edge of the sheets makes go sheets strongly hydrophilic, allowing them to readily swell and disperse in water...
