Poly(Vinyl Alcohol) (PVA) films were prepared with AlCl3·6H2O/glycerin and AlCl3·6H2O/poly glycerin as two kinds of complex plasticizer. The micromorphology of pure PVA film and PVA films plasticized with complex plasticizer was observed by Scanning Electron Microscope (SEM). The interaction between complex plas...

In the title compound, [Cd(C4H5NO4)(H2O)2] n , the Cd(II) atom exhibits a distorted octa-hedral coordination geometry, defined by one N atom and three O atoms from two iminodi-acetate (IDA) ligands and two water molecules. The tridentate IDA ligand additionally bridges via one of its carboxylate O atoms to another Cd(II) atom, thus forming a zigzag chain along [001]. A three-dimensional network...

The title cadmium derivative of benzyl-oxyacetic acid, [Cd(C(9)H(9)O(3))(2)](n), exists as a μ(2)-carboxyl-ate-bridged layer network. Two benzyl-oxyacetate units each chelate the metal through a carboxylate as well as through the ether O atoms; the metal is also coordinated by the double-bond carbonyl O atom of two adjacent benzyl-oxyacetate units in an octa-hedral geometry. The metal atom lies...

We have examined the thermodynamics of binding of a series of oligolysines (net charge z = +2 to +10) containing one, two, or three tryptophans to several single-stranded (ss) homo-polynucleotides [poly(A), poly(C), poly(I), poly(dU), poly(dT)] and duplex (ds) DNA in order to investigate the effects of peptide charge, tryptophan content, and polynucleotide base and sugar type. Equilibrium assoc...

A highly efficient, simple and green solvent-free protocol for the preparation of poly-substituted quinolines via Friedländer hetero-annulation reaction between 2-aminoaryl ketones and carbonyl compounds in the presence of silica-supported P2O5 (P2O5 / SiO2) is described. In this method, the title compounds are obtained in high to exc...
