Do Specific Ion Effects on Collective Relaxation Arise from Perturbation of Hydrogen-Bonding Network Structure?

June 24, 2024

Author(s)

Jennifer Clark, Jack F. Douglas

The change in the transport properties (i.e., water diffusivity, shear viscosity, etc.) when adding salts to water has been used to classify ions as either being chaotropic or kosmotropic, a terminology based on the presumption that this phenomenon arises

Dielectric Characterization of H2O and CO2 Uptake by Polyethylenimine Films

April 10, 2024

Author(s)

Jan Obrzut, Jennifer Clark, Avery Baumann, Jack F. Douglas

This study investigates the dielectric properties of branched polyethylenimine (PEI) films in relation to their interaction with moisture and CO2. The dielectric measurements were carried out using a non-contact resonant microwave cavity testing method

Molecular Dynamics Simulation of the Influence of Temperature and Salt on the Dynamic Hydration Layer in a Model Polyzwitterionic Polymer PAEDAPS

September 5, 2023

Author(s)

Jennifer Clark, Vivek Prabhu, Jack F. Douglas

We investigate the hydration of poly(3-[2-(acrylamido)ethyldimethy-lammonio]propanesulfonate) over a range of temperatures in pure water and with the inclusion of 0.1 mol / L NaCl using atomistic molecular dynamics simulation. Drawing on concepts drawn
