Instrumentation for time-resolved small-angle neutron scattering measurements with sub-millisecond time resolution, based on Gähler's TISANE (time-involved small-angle neutron experiments) concept, is in operation at NIST's Center for Neutron Resear

We examine quantitatively the instrumental factors that affect the theoretical performance and practical application of conventional pinhole collimation and focusing optics for small-angle neutron scattering (SANS) measurements. We calculate the rela

In a neutron diffraction measurement, including small-angle scattering, there is generally a featureless (i.e.Q-independent) component due to incoherent scattering. This scattering contains no information about the atomic structure or structure on an

Changes in the nanoscale structure of semicrystalline polyethylene (PE) resulting from the sorption/diffusion of hexane-d14 vapor have been observed and quantified by in situ vapor sorption small-angle neutron scattering (iVSANS). We find a linear co

Several poly(perfluorosulfonic acid) membranes (NAFION, EW = 1100) with the same sulfonic acid content were systematically investigated with SANS under in-situ water vapor sorption and/or with bulk water to quantify the effects of relative humidity (

Ultra small angle neutron scattering (USANS) and SANS measurements, covering length scales from nanometers to micrometers, were made to investigate the structure of monolithic porous Vycor. 1 USANS from dry Vycor showed strong very low angle scatteri

Fulvic acids (FA) and humic acids (HA) constitute 30–50% of dissolved organic matter in natural aquatic systems. In aqueous solutions, a commonly accepted view is that FA and HA exist as soluble macroligands at low concentration and as supramolecul

SANS has not been successfully applied to study the structure of semicrystalline polyolefins without deuterated polymers because of the fundamental limitation of negligible contrast between the crystalline and amorphous phases in spite of the mass de

The aim of this study is to determine the effects of oil solutes and alcohol cosolvents on the structure of oil-in-water microemulsions stabilized by poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) triblock copolymers. T

We have investigated the dispersion of single-walled carbon nanotubes (SWNTs) in heavy water with the surfactant octyl-phenol-ethoxylate (Triton X-100) using small angle neutron scattering. The results indicate an optimal surfactant concentration for
