Their paper, "Stress Development and Film Formation in Multiphase Composite Latexes" concluded that it is possible to produce soft core/hard shell latex materials, in terms of their film formation and their applications in binders in paint formulations. The first author on the paper is CEMS/CPFP graduate student Kyle Price, and co-authors are Wenjun Wu and Kurt Wood from Arkena Inc., undergraduate researcher Stephanie Kong, Prof. Alon McCormick, and Prof. Lorraine Francis. The research was primarily supported by the NSF GOALI program with Kong's undergraduate research support from the NSF MRSEC REU program. The team was presented with a trophy and a check for$2,500 in prize money.
