In the title compound, [Y(2)(C(4)H(4)O(4))(2)(C(2)O(4))(H(2)O)(2)](n), the flexible succinate anion assumes a gauche conformation and bridges the eight-coordinated Y atoms, generating two-dimensional layers parallel to (010). The coordination polymer layers are linked into a three-dimensional framework by the rigid oxalate ligands. The oxalate ions are located on a center of inversion. Inter-mo...

In this work, we present a theoretical framework that unifies polymer field theory and density functional theory in order to efficiently predict ordered nanostructure formation of systems having considerable complexity in terms of molecular structures and interactions. We validate our approach by comparing its predictions with previous simulation results for model systems. We illustrate the fle...

This paper reviews recent progress in the studies on polymer surfaces/interfaces using sum frequency generation (SFG) vibrational spectroscopy. SFG theory, technique, and some experimental details have been presented. The review is focused on the SFG studies on buried interfaces involving polymer materials, such as polymer–water interfaces and polymer–polymer interfaces. Molecular interactions ...

application of supramolecular polymer blending in preparation of materialswith adjustable mechanical properties is addressed. it is anticipated that the microstructure and properties of polymer blends are drastically controlled by the inter-molecular interactions. on this basis, the effect of strongly dimerising ureidopyrimidinone end groups (upy) with the capability of quadruple hydrogen bondi...

One of the newest of viscoelastic RANS turbulence models for drag reducing channel flow with polymer additives is studied in different flow and rheological properties. In this model, finitely extensible nonlinear elastic-Peterlin (FENE-P) constitutive model is used to describe the viscoelastic effect of polymer solution and turbulence model is developed in the k-ϵ-(ν^2 ) ̅-f framework. The geome...

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...

Biocompatible nanomaterials and hydrogels have become an important tool for improving cell-based therapies by promoting cell survival and protecting cell transplants from immune rejection. Although their potential benefit has been widely evaluated, at present it is not possible to determine, in vivo, if and how long cells remain viable following their administration without the use of a reporte...

Low-cost, low power consumption gas sensors that can detect or quantify various gas analytes are of increasing interest for various applications ranging from mobile health, to environmental exposure assessment and homeland security. In particular miniature gas sensors based on nanomaterials that can be manufactured in the form of sensor arrays present great potential for the development of port...
