Expandable graphite/polyamide-6 nanocomposites

Expandable graphite/polyamide-6 nanocomposites

Polyamide-6 (PA-6)/graphite nanocomposites were prepared by melt blending, using a variety of graphites, including virgin graphite, expandable graphites and expanded graphite. The resulting nanocomposites were characterized by X-ray diffraction, thermogravimetric analysis, cone calorimetry, and tensile mechanical analysis. Nanocomposite formation does occur, as denoted by the nanometre dispersi...

Expandable DNA Repeat and Human Hereditary Disorders

Background & Aims: Nearly 30 hereditary disorders in humans result from an increase in the number of copies of simple repeats in genomic DNA, including fragile X syndrome, myotonic dystrophy, Huntington’s disease, and Friedreich’s ataxia. One the most frequently occurring types of mutation is trinucleotide repeat expansion. The present study was conducted with the aim of investigating the cause...

Expandable factor analysis.

Bayesian sparse factor models have proven useful for characterizing dependence in multivariate data, but scaling computation to large numbers of samples and dimensions is problematic. We propose expandable factor analysis for scalable inference in factor models when the number of factors is unknown. The method relies on a continuous shrinkage prior for efficient maximum a posteriori estimation ...

Presenting dynamically expandable hypermedia

The Multimedia Information Presentation System (MIPS) will allow end-users to browse multimedia information presented in a user-friendly and consistent manner. In its most powerful configuration, it will allow the end-user to formulate queries which are interpreted, analysed , and despatched by the system to heterogeneous distributed external data sources, and to view a coherent and customized ...
