Vibrational dynamics of solid poly ( ethylene oxide )

Molecular dynamics (MD) simulations of crystalline poly(ethylene oxide) (PEO) have been carried out in order to study its vibrational properties. The vibrational density of states has been calculated using a normal mode analysis (NMA) and also through the velocity autocorrelation function of the atoms. Results agree well with experimental spectroscopic data. System size effects in the crystalli...

High-pressure vibrational properties of polyethylene.

The pressure evolution of the vibrational spectrum of polyethylene was investigated up to 50 GPa along different isotherms by Fourier-transform infrared and Raman spectroscopy and at 0 K by density-functional theory calculations. The infrared data allow for the detection of the orthorhombic Pnam to monoclinic P2(1)∕m phase transition which is characterized by a strong hysteresis both on compres...

Chemical Dynamics of Monodispersed Iron Oxide Nanoparticles

This study is comprised of the synthesis and characterization of uniform fine particles of iron oxide in different shapes and sizes. Varying amounts of iron (III) chloride and sodium dihydrogen phosphate was heated at 98 oC for various periods, following the forced hydrolysis method. Scanning electron microscopic analysis showed that the shape and size of the precipitated particl...

The Use of Binary Polymeric Networks in Stabilizing Polyethylene Oxide Solid Dispersions.

The objective of this study was to determine if a high Tg polymer (Eudragit(®) S100) could be used to stabilize amorphous domains of polyethylene oxide (PEO) and hence improve the stability of binary polymer systems containing celecoxib (CX). We propose a novel method of stabilizing the amorphous PEO solid dispersion through inclusion of a miscible, high Tg polymer, namely, that can form strong...
