In this work, amidoxime polyacrylonitrile (AOPAN) nanofibrous membrane was prepared by a reaction between PAN nanofibers and hydroxylamine hydrochloride. The AOPAN nanofibrous membranes were used for four metal ions (Fe, Cu, Ni, Cd) chelation under different conditions. Further, the competition of different metal ions coordinating with AOPAN nanofibrous membrane was also studied. The AOPAN chel...

The novel boron-chelated π-conjugated polymers named as BF2-poly and BPh2-poly were synthesized by a feasible condensation-chelation strategy. First, conjugated polymers bearing Boc group were prepared by using palladium-catalyzed Suzuki–Miyaura coupling reaction. Then, conjugated polymers (poly-1) were obtained with high efficiency by removing the Boc group from Boc-poly. Last, boron trifluori...

The Zn(II) atom in the title compound, [Zn(C(8)H(7)N(3)O(2)S)(C(10)H(8)N(2))], is N,N'-chelated by the heterocycle and N,O,S-chelated by the doubly deprotonated Schiff base ligand in a distorted square-pyramidal environment. O-H⋯O and N-H⋯N hydrogen bonds link adjacent mol-ecules into a layer structure.

The Z-selective ethenolysis activity of chelated ruthenium metathesis catalysts was investigated with experiment and theory. A five-membered chelated catalyst that was successfully employed in Z-selective cross metathesis reactions has now been found to be highly active for Z-selective ethenolysis at low ethylene pressures, while tolerating a wide variety of functional groups. This phenomenon a...

The interactions in the tertiary structure of a ribosomal RNA fragment in the GTPase Associating Center (GAC) have been experimentally studied, but the roles of the bound and diffuse cations in its folding pathway have not yet been fully elucidated. Melting experiments have shown that the temperature of the first of the two distinguishable transitions in the unfolding pathway of the GAC RNA can...

A series of new heteroleptic chelated copper(II) complexes that encompass N,N-dibezyl substituted derivative of ethylenediamine (X-diamine) and acetylacetonate (acac) were prepared.  The IR and electronic absorption spectra and the molar conductivity of the complexes are presented and discussed.  The molar conductivity values of the complexes in different solvents reveals a predominance of elec...

the presented study aimed at investigating the effect of foliar application of amino acids and nano particles and chelated iron on photosynthetic pigments and yield of potato. to this end a factorial experiment was carried out in the form of randomized complete block design with three replications in 2013, in the research field of natural resources institute in damavand, iran. the first factor ...

Nano fertilizers are new products which contain readily available nutrients in the nano scale range and are preferred largely due to their efficiency. This research was conducted to assessment the effect of nano chelated of micro nutrient on agronomic traits of Cowpea via factorial experiment based on randomized complete block design with four replications during 2016 seasonal year. The treatme...
