Author(s)
Jonathan E. Seppala, Anthony P. Kotula, Chad R. Snyder

Tunable Mechanical Anisotropy, Crack Guiding, and Toughness Enhancement in Two-Stage Reactive Polymer Networks

June 13, 2019
Author(s)
Lewis M. Cox, Adrienne K. Blevins, Jasper A. Drisko, Yifu Ding, Callie I. Higgins, Rong Long, Christopher N. Bowman, Jason P. Killgore
Photopolymers are a versatile group of materials that enable intricate geometric control over printed part geometries in advanced manufacturing processes. However, manufacturing methods attempting to spatially control material heterogeneity within printed

Creating Training Data for Scientific Named Entity Recognition with Minimal Human Effort

June 8, 2019
Author(s)
Roselyne B. Tchoua, Aswathy Ajith, Zhi Hong, Logan T. Ward, Kyle Chard, Debra Audus, Shrayesh N. Patel, Juan J. de Pablo, Ian Foster
Scientific Named Entity Referent Extraction is often more complicated than traditional Named Entity Recognition (NER). For example, in polymer science, chemical structure may be encoded in a variety of nonstandard naming conventions, and authors may refer

Controlled Growth of Polyamide Films atop Homogeneous and Heterogeneous Hydrogels using Gel- Liquid Interfacial Polymerization

May 22, 2019
Author(s)
Mengyuan Wang, Christopher Stafford, Lewis M. Cox, Adrienne K. Blevins, Masoud Aghajani, Jason Killgore, Yifu Ding
Interfacially polymerized polyamide (PA) layers dictate the permselective performance of thin film composite (TFC) membranes. Extensive effort has been focused on understanding and ultimately controlling the structure and morphology of the PA layers on

Mechanisms of spontaneous chain formation and subsequent microstructural evolution in shear- driven strongly confined drop monolayers

May 18, 2019
Author(s)
Sagnik Singha, Abhilash R. Malipeddi, Mauricio Zurita-Gotor, Kausik Sarkar, Kevin Shen, Michael Loewenberg, Kalman D. Migler, Jerzy Blawzdziewicz
It was experimentally demonstrated by Migler and his collaborators [Phys. Rev. Lett. 2001, 86, 1023; Langmuir 2003, 19, 8667] that a strongly confined drop monolayer sheared between two parallel plates can spontaneously develop a flow-oriented drop-chain

Stable Postfullerene Solar Cells via Direct C-H Arylation Polymerization. Morphology-Performance Relationships

May 16, 2019
Author(s)
Subhrangsu Mukherjee, Thomas Aldrich, Weigang Zhu, Lee J. Richter, Eliot Gann, Dean DeLongchamp, Antonio Facchetti, Ferdinand Melkonyan, Tobin Marks
The scope of the environmentally benign direct C-H arylation polymerization (DARP) process is validated and significantly extended in the synthesis of a high-performance benzodithiophene- based copolymer series, PBDT(Ar)-FTTE, with previously untested and

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

Environmental Friendly Flame Resistant Coatings for Soft Furnishing

May 1, 2019
Author(s)
Yeon S. Kim, Yu-Chin Li, John R. Shields, Rick D. Davis
Pending flammability regulations and scrutinizing of the environment and health consequences of fire retardants is creating opportunities for novel and “greener” technologies to reduce the flammability of residential furniture. This presentation will

Corona Treatment for High-Throughput, Layer-by-Layer Nano-Transfer Molding

April 2, 2019
Author(s)
Michael Deagan, Edwin Chan, Linda S. Schadler, Chaitanya Ullal
Corona discharge treatment offers a facile, robust, and scalable technique for adhesion promotion in nano-transfer molding. In contrast to conventional plasma treatment, which requires vacuum operation, corona treatment at ambient pressure enabled

Influence of Knot Complexity on Glass-Formation in Ring Polymer Melts

March 13, 2019
Author(s)
Luis F. Vargas Lara, Beatriz Pazmino, Jack F. Douglas
We perform molecular dynamic simulations on a coarse-grained polymer melt to study the dynamics of glass-formation in ring polymer melts of variable knot complexity. After generating melts of non-concatenated polymeric rings having a range of minimum

Raman Imaging of Surface and Sub-Surface Graphene Oxide in Fiber Reinforced Polymer Nanocomposites

March 1, 2019
Author(s)
Amber D. McCreary, Qi An, Aaron M. Forster, Kunwei Liu, Siyao He, Chris Macosko, Andreas Stein, Angela R. Hight Walker
The incorporation of nanofillers, such as graphene oxide (GO) into fiber reinforced polymer composites to improve their mechanical properties is a significant research area for a variety of industrial applications. However, to date there is no reliable

Targeting hMSC Response via Surface Carbonyl Groups, Contact Angle, and Protein Interactions

March 1, 2019
Author(s)
Max J. Lerman, Shinichiro Muramoto, Navein Arumugasaamy, Michael Van Order, Josephine Lembong, Anushka Gerald, John G. Gillen, John P. Fisher
Traditional 2D culture systems made of polystyrene (PS) require the addition of surface chemistry beyond the nominal phenyl groups present to facilitate and encourage cell adhesion. Determining the surface properties which enhance protein adhesion from

Lower critical solution temperature in polyelectrolyte coacervates

February 26, 2019
Author(s)
Samim Ali, Markus Bleuel, Vivek Prabhu
Model linear oppositely-charged polyelectrolyte complexes exhibit a lower critical solution temperature. The coexist-ence curves narrow with increasing monovalent salt concentration (Cs) that lowers the polymer concentration (Cp) in the polymer-rich phase
