This short paper describes several ex~ perimentai approaches for dealing with chemical reactions or decomposition which can occur when making thermo physical property measurements at high temperature and high pressure. The as sociated equipment w

A constant stress Couette cell rheometer has been modified to measure simultaneously the viscometric properties and neutron scattering intensities from the NIST Center for Neutron Research (NCNR) small angle neutron scattering (SANS) spectrometers. T

The structure of cylindrical aqueous micellar solutions was studied by small angle neutron scattering and light scattering in equilibrium and under shear. In equilibrium, the micelles behave as randomly oriented, rigid cylinders with an exponential d

Small-angle neutron scattering (SANS) studies have been carried out on a binary mixture of polystyrene-h{sub 8} particles (A, radius 168 A) and polystyrene-d{sub 8} particles (B, radius 510A). Two dispersions were prepared at a total volume fraction

Computer simulations of a two-dimensional Lennard-Jones fluid undergoing spinodal decomposition are reported for the system subjected to planar Couetic flow. Key results are the images of the atomic structure and plots of the corresponding pair corre

The structure of a cationic worm-like cylindrical micelle was investigated by SANS (small-angle neutron scattering). Intensities from 0.1% by weight solutions in D2O, at rest and under shear, were measured on the NIST Cold Neutron Research facility 3

There is need to understand the structure of hard-sphere dispersions under flow in order to develop models for colloid rheology since changes in structure are related to non-Newtonian behaviour. Small-angle neutron scattering (SANS) data for polymer

Small-angle neutron scattering profiles from a concentrated (65 wt%) polystyrene-polyisoprene block copolymer solution in dioctyl phthalate under shear were obtained both above and below the quiescent order--disorder transition (ODT). The ordered sol
