High-resolution Methods for Soft Matter
Dynamic Investigation
| Learning Resources | Schedule | Registration |
Purpose
This tutorial is primarily aimed at graduate students, postdocs, and young faculty working on soft matters who are interested in the unique capabilities offered by backscattering and neutron spin-echo spectrometers to probe the dynamics of their systems at the nanoscale. The first part of the tutorial will provide theoretical foundations. The second part will offer a hands-on exercise on a case study covering experiment design, sample preparation, data reduction, and analysis. Brief scientific presentations demonstrating the use of these methods will also be presented.
Time & Venue
Sunday 06/23/2024, Crown Plaza, Knoxville TN
Free registration opens now through June 1, 2024 through ACNS 2024 Registration
FREE lunch for registered participants is sponsored by Crosscutting Science Initiative for Chemistry, Geochemistry and Environmental Chemistry at the Neutron Scattering Division, ORNL
Background
Both neutron spin-echo (NSE) and backscattering spectroscopy (BSS) are quasi-elastic neutron scattering techniques. NSE has the highest energy resolution among other neutron spectroscopic methods, allowing it access to slow dynamics, such as large domain motions of flexible proteins, rouse motions of polymer chains, and biomembrane undulation and thickness fluctuations. NSE typically probes over a time scale from 1 ps to a few hundred ns at length scales of 1 nm to 50 nm. On the other hand, BSS studies faster atomic or molecular dynamics, such as bond vibration and backbone rotation in polymers and proteins, as well as lateral diffusion and rotation of lipids. BS specializes in shorter times, from a few ps to a few ns range, at smaller lengths of a few Å to 10 nm.
