Temperature and light intensity effects on the photodegradation of high-density polyethylene

May 11, 2019
Author(s)
Andrew W. Fairbrother, Hsiang C. Hsueh, Jae Hyun Kim, Deborah S. Jacobs, Lakesha N. Perry, David G. Goodwin, Christopher C. White, Stephanie S. Watson, Li Piin Sung
The photodegradation of polymers poses a serious challenge to their outdoor application, and results in significant financial loss due to early or unexpected system failure. A better understanding of their degradation kinetics aids the improvement of

Effects of Consumer Use Practices on Nanosilver Release from Commercially Available Food Contact Materials

October 23, 2018
Author(s)
Susana Addo Ntim, Samuel R. Norris, David Goodwin, Jens Breffke, Keana Scott, Li Piin Sung, Treye Thomas, Gregory O. Noonan
Migration evaluation involving nano-enabled food contact materials (FCMs) mostly focus on potential nanoparticle release from new unused products. This may not represent consumer use practices encountered by the FCMs in their lifecycle. In order to

Detection and Quantification of Graphene Family Nanomaterials in the Environment

March 5, 2018
Author(s)
David Goodwin, Adeyemi Adeyele, Li Piin Sung, Kay Ho, Robert Burgess, Elijah Petersen
An increase in production of commercial products containing graphene-family nanomaterials (GFNs) has led to concern over their release into the environment. The fate and potential ecotoxicological effects of GFNs in the environment are currently unclear

Performance and Aging of Graphene Oxide/Polyurethane Nanocomposites

May 14, 2017
Author(s)
David G. Goodwin
Polymer nanocomposites (PNCs) containing graphene oxide (GO) can be used to enhance the mechanical strength, thermal properties, and barrier properties of a polymer. Although the properties of graphene are generally superior to GO, GO nanofillers are more
