Out now @MacroJrnls_ACS! We present an analysis to model non-Gaussian polymer conformations from scattering & simulation. Link here, & follow along below for a tweetorial on using non-Gaussian descriptors to understand polymer structures & properties!🧵 /1 doi.org/10.1021/acs.macromol…

A Gram–Charlier Analysis of Scattering to Describe Nonideal Polymer Conformations

Theories of interpreting polymer physics and rheology at the molecular level from experiments, including small-angle scattering, typically rely on the assumption that polymer chains possess a...

This work was led by @anuktaDT, and stemmed from a @doescience collaboration with Patrick Underhill & his student Tina Wang @RPIEng. Thanks to Rachel Segalman, Shawn Mengel and Audra DeStefano @UCSBengineering for contributing the experiments on polypeptoids. Cheers! /15 /🧵

p.s. If you’d rather see the work in person, @professor_meh will present a talk on GCAPS at the @SORheology Annual Meeting on Thursday at 10:55am. Or - if you aren't a the conference that long, come find him to get a preview of the talk #EverythingFlows #NotEverythingIsGaussian
