Preparation and characterization of poly(methyl methacrylate)–clay nanocomposites via melt intercalation: The effect of organoclay on the structure and thermal properties
TL;DR: In this paper, a wide-angle X-ray diffraction, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC) was performed on PMMA-montmorillonite hybrid, which showed the existence of a glass transition temperature (Tg) for all the hybrids and also showed that the Tg of the hybrids were lower (by ∼10%) compared to that of PMMA.
Journal ArticleDOI
Synthesis and characterization of novel organo-montmorillonites
TL;DR: In this paper, a wide angle X-ray diffraction (WAXD) and thermogravimetric analysis (TGA) technique was used to characterize the structure and thermal stability of organo-montmorillonites (OMMT) clays.
Journal ArticleDOI
Ultrafine Metal Particle Formation in Reverse Micellar Systems: Effects of Intermicellar Exchange on the Formation of Particles
TL;DR: In this paper, a modeling approach is developed to account for the important effects of intermicellar exchange on the ultrafine particle formation in reverse micelles, and a set of fusion−fission schemes are specifically proposed and used for modeling inter-miceLLar metal exchange.
Journal ArticleDOI
Origin of the Difference in Structural Behavior of Poly(acrylic acid) and Poly(methacrylic acid) in Aqueous Solution Discerned by Explicit-Solvent Explicit-Ion MD Simulations
TL;DR: In this article, the conformational and hydration behavior of poly(acrylic acid) and poly(methacrylic acids) in dilute aqueous solution, as a function of charge density, is studied using two different sets of force field parameters: FF-1 and FF-2.
Journal ArticleDOI
Molecular View into the Cyclodextrin Cavity: Structure and Hydration.
TL;DR: This is the first computational study that maps the conformational change to the preferential hydrogen bond donating capacity of one of the secondary hydroxyl groups of CD, in consensus with an NMR experiment, and develops a simple and novel geometry-based technique to identify water molecules occupying the nonspherical CD cavity.
