Dick Research Group develops a deployable, cost-effective sensor to detect contaminants in drinking water

The Dick Research Group is focused on creating new sensor technology for the detection of PFAS, a group of synthetic “forever” chemicals. Doctoral student Rebecca Clark is conducting research on the effectiveness of the sensor’s ability to detect PFOS, a pollutant in the PFAS group.

A Generalized Potentiostat Adaptor for Multiplexed Electroanalysis

We present a versatile strategy for the development of flexible printed circuit (FPC) electrode arrays with accompanying multiplexing hardware to interface with single-channel potentiostats.

Atmospheric Deposition and Annual Flux of Legacy Perfluoroalkyl Substances and Replacement Perfluoroalkyl Ether Carboxylic Acids in Wilmington, NC, USA

This study shows the first direct evidence of PFECAs in wet and dry deposition. The data suggest that the particle-bound and gas-phase PFAS that may have undergone long-range transport can be incorporated into raindrops and removed rapidly.

Stretch-Induced Cavitation: How Critical Cavity Radius and Barrier Energy, Radius, and Energy of a Stable Cavity Depend on the Stretching Factor

In this work, we study how the characteristics of the cavitation mentioned above scale with the amount of applied tension.

PFOS dominates PFAS composition in ambient fine particulate matter (PM2.5) collected across North Carolina nearly 20 years after the end of its US production

Thirty-four PFASs, including perfluoroalkyl carboxylic, perfluoroalkane sulfonic, perfluoroalkyl ether carboxylic and sulfonic acids were analyzed by UHPLC/ESI-MS/MS.
