They aim to establish...
- The National Science Foundation (NSF) Division of Chemistry awarded a $678,642 Project Grant to Professor Donghui Zhang of Louisiana State University (LSU) to study the structures of micellar assemblies of ionic polypeptoid block copolymers (BCPs). The research aims to understand how the charge pattern and chemical identity of ionic monomers in these polymers modulate their aqueous micellar assemblies across dilute to semi-dilute concentration regimes. The project has three key objectives: (1)...
This $280,000 National Science Foundation Division of Chemistry project grant supports collaborative research between Virginia Polytechnic Institute and State University and Pennsylvania State University to develop robust methods for determining the molecular weight and polydispersity of polyelectrolytes. The researchers will focus on scaling theory and experimental techniques using solution rheology, X-ray scattering, and NMR diffusometry to measure the number-average molecular weight of polyelectrolytes. A key objective is establishing well-defined strategies and parameter spaces for practical application of these measurement methods in the semi-dilute unentangled regime. The researchers also aim to quantify polydispersity for polyelectrolytes using NMR spectroscopy and explore applicability of the methods to neutral polymers. This award furthers the goals of the NSF Mathematical and Physical Sciences program to strengthen the nation's scientific enterprise through increasing fundamental knowledge and understanding of major problems in these fields.
