Molecular Simulation in Polymer Science: Understanding Experiments Better

New techniques and applications of atomistic molecular simulation methods are reported. Their aim is to provide a better understanding of the molecular basis of experimental results. To this end, calculations are performed of experimentally measurable observables. These are then compared to experimental results, thus validating the computational models and procedures. Finally, the simulations a...

A Scientific Multimedia Database System for Polymer Science Experiments

| This paper describes SciMMDB, a scientiic multimedia database system designed for Polymer Science experiment data applications. SciMMDB maintains multi-media data of type video, text and picture (as well as other standard data types), and allows users to (1) form multi-media presentation streams about experiments, (2) deene a presentation which organizes a number of presentation streams for p...

Molecular physics of a polymer engineering instability: experiments and computation.

Entangled polymer melts exhibit a variety of flow instabilities that limit production rates in industrial applications. We present both experimental and computational findings, using flow of monodisperse linear polystyrenes in a contraction-expansion geometry, which illustrate the formation and development of one such flow instability. This viscoelastic disturbance is observed at the slit outle...

Understanding "understanding" in Public Understanding of Science.

This study examines the conflation of terms such as "knowledge" and "understanding" in peer-reviewed literature, and tests the hypothesis that little current research clearly distinguishes between importantly distinct epistemic states. Two sets of data are presented from papers published in the journal Public Understanding of Science. In the first set, the digital text analysis tool, Voyant, is...
